Gas stoves have become one of the most popular cooking appliances in Centurion homes and commercial kitchens — and with good reason. They deliver precise heat control, immediate response, and continue to work through load shedding when electric stoves cannot. But when a gas stove develops a fault, it must be repaired correctly. Gas appliances involve combustible fuel, pressurised gas supply circuits, and safety devices that exist to prevent serious incidents. Repairs should only be carried out by technicians with the correct training and certification to work on gas appliances safely and compliantly.
Centurion Appliance Repairs provides professional gas stove repairs in Centurion for residential and commercial clients. Our certified technicians are qualified to work on LPG gas stoves, freestanding gas ranges, built-in gas hobs, and combination gas stoves with electric ovens. We carry the most commonly needed gas stove components in our service vehicles — thermocouples, ignition electrodes, spark modules, burner parts, and gas valves — and resolve the majority of gas stove faults on the first visit.
We also carry out gas leak detection and gas stove servicing for clients across all Centurion suburbs.
If you can smell gas: Do not attempt to light the stove or any other appliance. Do not switch any electrical switches on or off. Open windows and doors to ventilate the space. Turn off the gas supply at the cylinder or at the isolating valve. Leave the building and call us immediately on 079 976 2941.
For all other gas stove faults, call 079 976 2941 or WhatsApp for same-day repair in Centurion.
Gas stove repairs are categorically different from most other appliance repairs. Incorrect work on a gas appliance — a poorly fitted connection, a bypass of a safety device, or a component replaced with an incorrect specification — can result in a gas leak, a carbon monoxide accumulation, or an uncontrolled ignition event. These are not theoretical risks. They are the reason gas appliance repairs in South Africa must be carried out by technicians who are trained and competent to work on gas appliances in compliance with SANS 10087 — the South African standard for the handling, storage, distribution, and use of liquefied petroleum gas.
Our technicians hold the relevant gas appliance competency and carry out all gas stove repairs in compliance with SANS 10087 requirements. Every repair is completed with a safety check before the appliance is returned to service — confirming that there are no leaks at any connection worked on, that all safety devices are functioning correctly, and that the flame characteristics of each burner are within the normal range.
Do not use operators who are not qualified to work on gas appliances. The cost of a correct, compliant repair is always less than the cost of the consequences of an incorrect one.
A gas burner that produces no spark when the knob is turned, or that sparks but does not produce a flame, is the most common gas stove complaint we attend to across Centurion.
The ignition system on most modern gas stoves uses a piezoelectric or electronic spark igniter to ignite the gas as the knob is turned and the gas flow opens. When this system fails, the burner cannot be lit in the normal way.
A blocked burner port is the most common cause and is not a component fault at all — it is a maintenance issue. Food spillovers, grease, and cleaning product residue can block the gas jets or burner ports that allow gas to reach the ignition point. If the igniter is sparking visibly but no flame develops, blocked ports are the most likely cause. Our technicians clean and clear burner ports as part of a service visit and demonstrate the correct cleaning technique to clients to prevent recurrence.
A misaligned burner cap is another common cause of ignition failure that is not a component fault. The burner cap must sit correctly on the burner head for the gas outlet holes to align with the ignition point. After cleaning, burner caps are often replaced slightly off-centre, preventing correct ignition. Repositioning the cap correctly resolves this immediately.
A failed ignition electrode is the component responsible for producing the spark. The electrode is a ceramic-insulated rod mounted adjacent to the burner. Over time, the ceramic body of the electrode can crack — most often from thermal cycling or from cleaning liquid entering the ceramic — allowing the high-voltage spark to track to earth through the ceramic crack rather than jumping across to the burner. A cracked electrode produces a visible spark at the base of the ceramic rather than at the tip. Electrode replacement is a straightforward repair.
A failed spark module — the electronic board that generates and distributes the high-voltage pulse to the electrodes — can cause a single burner to fail to spark or all burners to fail simultaneously, depending on how the module is wired. We test the spark module output and replace it where the module is confirmed to be at fault.
Moisture in the burner assembly — particularly common after the stove has been cleaned with wet cloths or after a significant boilover — can prevent sparking and ignition temporarily. In most cases, allowing the stove to dry thoroughly resolves this. Our technicians check for moisture as part of the diagnostic process, particularly on units that have recently been cleaned or used heavily.
This is one of the most distinctive gas stove faults and it almost always points to one specific component — the thermocouple.
The thermocouple is a safety device fitted to most gas stoves and all gas hobs with flame failure protection. It is a small probe positioned in the path of the flame. When the flame heats the thermocouple, it generates a small electrical voltage that holds the gas valve open. When you hold the knob in after ignition, you are manually holding the gas valve open while the thermocouple heats up sufficiently to generate the voltage required to keep the valve open independently. Once the thermocouple is hot enough, you can release the knob and the valve remains open because the thermocouple is keeping it so.
If the flame goes out for any reason — a draught, a boilover, someone turning the knob inadvertently — the thermocouple cools rapidly, the voltage drops, and the gas valve closes automatically, preventing unburned gas from flowing into the kitchen.
When the thermocouple fails — through wear, heat damage, contamination with food residue, or age-related degradation — it no longer generates sufficient voltage to hold the valve open. The consequence is that the burner lights when you hold the knob in, but goes out the moment you release it. The safety device is doing its job, but the thermocouple is no longer able to generate the signal required to permit continued gas flow.
Thermocouple replacement is one of our most common gas stove repairs in Centurion. It is a straightforward repair in most cases and resolves the fault immediately. We carry thermocouples in our service vehicles for the most common gas stove brands sold in South Africa.
A correctly functioning gas burner produces a blue, stable flame that sits evenly around the burner crown. Deviations from this pattern are diagnostically meaningful.
A weak flame that is significantly smaller than normal indicates insufficient gas flow to the burner. The most common causes are a partially blocked gas jet, a partially closed or malfunctioning gas control valve, or low gas pressure at the appliance — which may indicate a nearly empty cylinder, a regulator that is under-performing, or a regulator that has not been set correctly for the cylinder pressure.
A yellow or orange flame indicates incomplete combustion — the gas is burning, but not cleanly. The most common causes are a blocked or dirty burner that is not allowing the correct air-to-gas mixture, or a primary air adjustment that is incorrect. A persistently yellow flame also produces soot and increases the carbon monoxide output of the stove, which is a health and safety concern. Yellow flames should be investigated and resolved promptly rather than accepted as normal operation.
A lifting or detached flame — where the flame lifts away from the burner crown and appears to hover above it — typically indicates excess gas pressure or too much primary air entering the burner. This can cause the flame to blow out at higher settings and is a fault condition that requires adjustment.
An uneven flame — where some ports of the burner crown are producing flame and others are not — indicates partially blocked ports on the affected sections. Burner cleaning resolves this in most cases.
Gas stoves with electronic auto-ignition systems — where turning any knob triggers clicking from all burners simultaneously — will sometimes enter a state where the clicking continues after the knob is released and does not stop. This is almost always caused by moisture in the ignition system or a wet spark module following a significant liquid spillover onto the hob surface.
When liquid enters the burner assemblies or reaches the spark module through the hob surface, it provides a conductive path that keeps the ignition circuit active. As the moisture dries, the clicking typically stops on its own. The stove should not be used while clicking continuously — if the moisture has reached the spark module it may need inspection and drying, and in some cases replacement if the board has been damaged.
Our technicians assess continuous clicking faults, dry and clean the ignition system, and replace the spark module where damage has occurred.
A persistent gas smell from the stove — not the brief smell of unburned gas that is normal in the moment before a burner lights — indicates a gas leak somewhere in the system. This is a safety issue that must be treated with urgency and should not be normalised or tolerated.
The smell of LPG (liquefied petroleum gas) is distinctive — the strong characteristic odour is deliberately added to the gas by suppliers as a safety warning since LPG is naturally odourless. If you can smell gas from the stove when it is not in use, or when it has been switched off, there is a leak in the gas circuit.
Leak points include the regulator connection to the cylinder, the hose between the regulator and the appliance, the hose-to-appliance connection fitting, and the internal gas valves and pipework within the stove. We carry out gas leak detection using a soap solution check and gas leak detection fluid on all connections, combined with an assessment of the regulator and hose condition.
Gas hose deterioration is one of the most common leak causes in Centurion homes. LPG hoses have a recommended replacement interval — typically five years for certified high-pressure hose — after which the hose becomes susceptible to cracking and perishing. Many homes have hoses that are significantly older than this. Hose replacement is an inexpensive repair that eliminates a significant safety risk.
Freestanding gas ranges and gas combination stoves have an oven section that operates on gas with its own burner, thermostat, and — on models with flame failure protection — its own thermocouple. Faults in the oven section are diagnosed and repaired separately from hob faults.
A gas oven that will not heat at all may indicate a failed oven igniter, a failed thermocouple in the oven burner circuit, a gas valve fault, or an oven thermostat that is stuck in the closed position. We diagnose each component systematically to identify the specific fault before recommending any repair.
A gas oven that heats but is inaccurate — burning food at settings where it should not, or failing to reach temperature for baking — most commonly indicates a failed oven thermostat. The oven thermostat on a gas range controls the gas valve and therefore the burner rate based on the oven temperature. A thermostat that has drifted out of calibration or failed causes the oven to run hotter or cooler than the dial setting indicates. Thermostat replacement or calibration is the standard repair for this fault.
An oven fan that is not functioning on a gas fan-assisted oven prevents even heat distribution — the area nearest the burner runs hot while the extremities of the oven remain cooler. Fan motor replacement restores even temperature distribution.
Gas stove control knobs must turn smoothly, engage the gas valve correctly at each setting, and return to the off position reliably. A knob that is stiff, does not engage correctly, or does not close off the gas flow when turned to off is a safety fault — not merely a cosmetic or convenience issue.
A knob that does not fully close off gas flow when turned to off will produce a persistent gas smell and a slow leak at the burner. This requires inspection of the control valve to determine whether the fault is in the knob assembly, the valve spindle, or the valve body itself. We repair and replace control knobs and valves for all major gas stove brands.
We also carry out repairs to the physical components of gas hobs and stove tops — replacing cracked or damaged pan supports, replacing lost or damaged burner caps, repairing or replacing damaged hob surfaces where these are causing operational problems, and servicing the door hinges, door seals, and glass panels on oven sections. A gas oven door that does not seal correctly wastes heat, causes uneven baking temperatures, and can cause the oven to take significantly longer to reach temperature.
Freestanding gas ranges Full gas stoves with both hob and oven sections operating on gas. These are the most common type in Centurion homes that have converted to gas cooking. We repair all faults on freestanding gas ranges from all major brands.
Gas hobs (built-in) Built-in gas hobs installed in kitchen counters, typically used in combination with a separate electric or gas oven. We repair burner faults, ignition faults, thermocouple faults, and gas valve faults on built-in gas hobs for all major brands.
Combination gas hob and electric oven ranges Very common in Centurion homes — the hob runs on gas while the oven is electric. We repair both the gas hob section and the electric oven section in a single visit.
Table-top gas stoves Single and two-burner table-top gas stoves used as primary cookers in apartments and as supplementary cooking appliances. We repair table-top units for all brands including Cadac, Totai, and other popular South African brands.
Commercial gas stoves and ranges Commercial gas ranges for restaurant kitchens, catering operations, hotels, and commercial food preparation facilities in Centurion. Commercial gas stoves operate under significantly higher gas pressures and with heavier-duty components than residential units. We repair commercial gas ranges and carry the thermocouple, valve, and burner components commonly used in commercial kitchen equipment.
We repair gas stoves from all major brands sold in South Africa, including:
Defy | Smeg | La Germania | Bosch | Siemens | AEG | Miele | Elba | Whirlpool | Samsung | LG | Hisense | Totai | Cadac | Thermocool | Univa | KIC | Kelvinator | Zanussi | Electrolux | Beko | Hotpoint | Bertazzoni | Falcon | Viking | Sub-Zero

In addition to fault repairs, we carry out annual gas stove servicing — a comprehensive inspection and cleaning service that keeps the appliance operating safely and efficiently and identifies developing faults before they become failures.
A full gas stove service from Centurion Appliance Repairs includes:
Full inspection of the gas supply circuit — cylinder, regulator, hose, and appliance connection — for condition and leaks. Soap solution and gas leak detector check on all connection points. Burner removal, cleaning, and port clearing on all hob burners. Ignition electrode condition inspection on all burners. Thermocouple condition assessment on all protected burners. Control valve inspection for correct operation and full gas shutoff at the off position. Oven burner inspection and cleaning. Oven thermocouple condition check. Oven door seal inspection. Flame appearance assessment on all burners after reassembly — confirming correct blue flame characteristics and no yellow or lifting flames. Full operational test on all settings before completion of the visit.
We recommend annual servicing for all gas stoves used regularly in Centurion homes. For commercial gas stoves in restaurant and catering environments, servicing every six months is advisable given the higher operating hours and greater fouling rate.
Gas stove adoption in Centurion has accelerated significantly since 2019 as load shedding made electric cooking unreliable. A large proportion of homes in Centurion’s estates and suburbs — Midstream Estate, Irene, Eldoraigne, Wierda Park, and Highveld among them — have converted to gas cooking either as a primary solution or as a backup alongside electric appliances.
This growing installed base means that gas stove repairs are now one of the most commonly requested appliance repair services in Centurion. The fault patterns we see most frequently reflect the age profile of the installed base — thermocouples and ignition electrodes wearing out on units that were installed four to six years ago, and gas hoses approaching or exceeding their replacement intervals on units converted during the early load shedding years.
If your gas stove was installed between 2018 and 2022 and has not been serviced since installation, an annual service visit is worthwhile — both to address any developing faults and to inspect the hose condition.

My gas burner lights but goes out when I release the knob — what is wrong? This is almost certainly a failed thermocouple. The thermocouple is the safety device that senses the flame and keeps the gas valve open once the flame is established. When it fails, it can no longer generate the voltage required to hold the valve open. The burner will light while you hold the knob in — because you are holding the valve open manually — but goes out the moment you release it. Thermocouple replacement is a straightforward repair that we carry out frequently in Centurion. Call us on 079 976 2941 to arrange a same-day visit.
My gas stove burner clicks continuously and will not stop — what should I do? Continuous clicking almost always indicates moisture in the ignition system — typically from a liquid spillover onto the hob surface. Turn the stove off at the gas supply and allow it to dry thoroughly. In most cases, the clicking stops on its own as the moisture evaporates. If it persists after 24 hours of drying, or if the stove was submerged in significant liquid, call us for an inspection. Do not leave the stove operating while it is clicking continuously.
I can smell gas from my stove even when it is off — what should I do? This is a safety issue. Turn off the gas at the cylinder immediately. Open windows and doors. Do not use any electrical switches. Leave the kitchen. Call us on 079 976 2941. A persistent gas smell when the stove is off indicates a leak — most commonly from a deteriorated gas hose, a loose connection, or a control valve that is not fully sealing at the off position. Do not use the stove until the leak has been located and repaired by a qualified technician.
How often should I have my gas stove serviced? We recommend annual servicing for domestic gas stoves used regularly, and six-monthly servicing for commercial gas stoves in restaurant and catering environments. A service visit includes gas hose and connection inspection, burner cleaning, thermocouple condition assessment, and a full safety check. If your stove was installed more than two years ago and has never been serviced, it is overdue.
My gas hose looks old and cracked — is this something I need to fix urgently? Yes. A cracked or perished gas hose is a gas leak waiting to happen — or may already be leaking at a rate too small to smell but significant enough to be a risk. Gas hoses have a recommended replacement interval and should be replaced as a precautionary measure when they show visible deterioration, discolouration, or cracking. Hose replacement is an inexpensive repair. Do not delay it.
Can you repair commercial gas stoves in Centurion restaurants and kitchens? Yes. We repair commercial gas ranges and hobs for restaurant kitchens, hotel kitchens, catering operations, and commercial food preparation facilities throughout Centurion. Commercial gas stove repairs are treated as priority callouts where a kitchen is unable to trade. Call us on 079 976 2941 and describe the fault and your situation.
Do you repair combination gas hob and electric oven stoves? Yes. Combination stoves — with a gas hob and an electric oven — are extremely common in Centurion and we repair both sections in a single visit. Our technicians are qualified to work on both the gas hob circuit and the electrical oven circuit, which is the correct combination of competencies for this type of appliance.
How much does gas stove repair cost in Centurion? Most gas stove repairs in Centurion fall between R700 and R1 800 depending on the fault and the parts required. The most common repairs — thermocouple replacement, electrode replacement, and burner cleaning — fall in the R700 to R1 350 range. More complex repairs such as gas valve or oven thermostat replacement are typically R900 to R2 500. A definitive quotation is provided on-site after diagnosis.
Do not live with a gas stove that is not working correctly — and do not attempt to bypass a safety device or operate a stove that you suspect has a gas leak. Call us now or send a WhatsApp message and we will have a certified local technician at your door, in most cases the same day.
