1. Oven Not Heating Properly
This is the most common reason people search for oven & cooker repair services. If your oven produces no heat — or noticeably less heat than usual — the fault is almost certainly in one of these parts:
- Heating element — burned out or broken (most common in electric ovens)
- Thermostat — failing to signal the element to switch on
- Temperature sensor — sending wrong readings to the control board
- Thermal fuse — blown to protect the appliance from overheating
- Gas igniter — failing to light the burner (gas ovens)
What You Can Check Yourself
Open your oven and look at the heating element. A broken element usually shows visible burn marks, blistering, or a crack in the coil. If you see any of these signs, stop using the appliance and arrange a repair.
For gas ovens, listen for a clicking sound when you turn the burner knob. No click and no ignition usually means a failed igniter — a straightforward fix for a qualified engineer.
When To Call A Professional
If the element looks fine but the oven still won’t heat, the thermostat or control board is likely the problem. These need specialist tools to diagnose. Contact Westminster Appliances to book an engineer visit.
2. Oven Not Reaching The Right Temperature
Your oven heats up, but food takes much longer than it should — or results are consistently poor even when you follow cooking timings. This is usually a thermostat or calibration problem.
Common Causes
- Faulty thermostat that cuts out too early or can’t hold the set temperature
- Temperature sensor giving wrong data to the control board
- Calibration drift — older ovens can lose accuracy over time
- Control board faults causing incorrect signals to the heating system
| ✅ Quick DIY Test: |
| Put an oven thermometer (a few pounds online) inside your oven. Compare its reading to the temperature you’ve set. A difference of more than 10–15°C strongly suggests a thermostat or sensor fault. Call an engineer if this is the case. |
3. Uneven Cooking Or Baking
Food comes out burnt on one side and undercooked on the other? The problem is almost always with the fan or airflow inside the oven.
Common Causes
- Fan motor failure — hot air stops circulating properly
- Damaged heating element creating hot and cold spots
- Blocked air vents from grease build-up
- Thermostat problems causing inconsistent temperatures
Fan oven repair is one of our most common requests. When the fan degrades — often gradually — cooking results get worse slowly, so many people don’t notice until the problem becomes serious.
4. Oven Fan Not Working
A dead fan in a fan-assisted oven effectively turns it into a conventional oven — slower cooking, worse results, and higher energy use.
Signs Of A Faulty Fan Motor
- Fan not spinning when the oven is switched on
- Food taking much longer to cook at the correct temperature
- Grinding or rattling sounds from the back of the oven
- Less airflow when you open the oven door
In most cases, the fan motor needs replacing. This is not a DIY job — the motor sits close to live components at the rear of the appliance. Our engineers carry out fan motor replacements regularly across London.
5. Oven Door Won’t Close Properly
A poorly sealed oven door wastes energy, affects cooking performance, and creates a burn risk. Fortunately, this is one of the more straightforward oven repairs.
Common Causes
- Worn or cracked door seal — heat escapes around the edge
- Damaged or misaligned hinges — door won’t sit flush
- Faulty latch — door won’t stay closed
- Physical damage to the door glass or frame
Door seals are wear-and-tear parts. Checking and replacing the seal every few years is a simple, low-cost step that noticeably improves your oven’s energy efficiency and cooking performance.
6. Oven Light Not Working
Not a safety issue on its own — but occasionally a sign of a wiring fault worth checking.
Possible Causes
- Burned-out bulb — the most common explanation
- Loose wiring at the bulb socket
- Faulty light socket needing replacement
| ✅ Safe DIY Fix: |
| Replacing an oven bulb is one of the few tasks you can safely do yourself. Switch the oven off and let it cool fully first. Use a replacement bulb rated for oven temperatures (typically 300°C). If a new bulb doesn’t fix the problem, call an engineer to check the wiring. |
7. Oven Making Strange Noises
A healthy oven runs quietly. Unfamiliar sounds are a warning sign — and ignoring them is one of the most common ways a small fault turns into an expensive repair.
Common Causes
- Worn fan motor bearings — produces a grinding or rumbling sound
- Loose internal components rattling inside the cavity
- Cooling fan faults — clicking or whirring after the oven is switched off
- Persistent cracking sounds (not the normal expansion noise)
| 💡 Act early and save money: |
| Fan motor bearings can deteriorate fast once they start to wear. A repair that costs £60 today can become a £200 job if left for a few months. |
8. Cooker Rings Or Hob Burners Not Working
When individual cooking zones fail — whether on an electric hob or gas burner — the fault can range from a simple switch issue to a wiring repair.
Common Causes
- Burned-out electric ring element
- Gas burner blocked with food debris
- Worn zone switches that no longer make a reliable connection
- Wiring faults between the switch and the element
- Ignition spark failure on gas hobs
| ⚠️ Gas Safety: |
| Gas hob faults must always be assessed by a Gas Safe registered engineer. Westminster Appliances carries out all gas work with fully qualified engineers. |
9. Oven Displaying Error Codes
Modern ovens use onboard diagnostics to show fault codes when something goes wrong. These codes are worth taking seriously — they tell you exactly what the appliance has detected.
Common Error Code Causes
- Temperature sensor failure (often F or E codes)
- Door lock faults on self-cleaning or pyrolytic ovens
- Control board communication errors
- Electrical irregularities triggering a protective fault code
First, look up the specific code in your appliance manual or on the manufacturer’s website. Then try a reset: switch off at the mains for 10 minutes. If the code comes back, a component has failed and needs replacing.
Our engineers carry diagnostic equipment for all major brands, including Bosch, Neff, Hotpoint, Smeg, and Indesit.
10. Oven Tripping The Electric
| ⚠️ This is the most serious fault on this list. |
| An oven that keeps tripping your circuit breaker is a potential electrical hazard. Do not simply reset the breaker and keep using the appliance. Call a professional immediately. |
Common Causes
- Faulty heating element with an internal short circuit
- Damaged wiring with degraded insulation
- Moisture inside the appliance after a spill or cleaning
- Control board fault causing an electrical short
Switch the oven off at the wall and do not use it until an engineer has inspected it. Book an emergency appliance repair with Westminster Appliances.
Safety Risks You Must Take Seriously
Several of the faults above carry genuine safety risks. Here is a clear summary.
Gas Leak Risk
| If you smell gas: |
| 1. Turn off the gas at the mains immediately |
| 2. Open windows and doors to ventilate the room |
| 3. Do not touch any electrical switches |
| 4. Leave the property |
| 5. Call the National Gas Emergency Service on 0800 111 999 from outside |
Carbon Monoxide Risk
Poor combustion in gas appliances can produce carbon monoxide — an odourless, colourless gas that can be fatal. Install a CO detector in your kitchen and have gas appliances serviced every year by a Gas Safe registered engineer.
Electrical Hazards
Do not attempt to repair internal electrical components yourself unless you are a qualified electrician. Oven wiring runs at mains voltage and presents a serious electric shock risk.
Fire Hazards
Grease build-up combined with overheating components is a real fire risk. Clean your oven regularly — especially around the heating element, grill pan, and base. This is one of the most effective preventive steps you can take.

Repair vs Replace: How To Make The Right Decision
One of the most common questions we get is whether it’s worth repairing an appliance or better to replace it. We’ve covered this in detail in our dedicated guide: Repair vs Replace: Which Is Better? — but here’s the practical summary.
Repair Your Oven If:
- It is under 10 years old and otherwise in good working order
- The repair cost is less than 50% of the price of a comparable new oven
- The fault is limited to a single component (element, thermostat, or fan motor)
- The brand has a good reliability record and spare parts are available
Consider Replacement If:
- The appliance is over 12–15 years old and has developed several faults
- Repair costs exceed half the price of a new equivalent appliance
- Energy efficiency is poor — older models can cost significantly more to run
- Spare parts are no longer available for the model
At Westminster Appliances, we always give you an honest assessment. If a repair doesn’t make financial sense, we will tell you — and we can help you source and install a replacement through our built-in appliance supply service.
How To Extend Your Oven’s Lifespan: 6 Simple Tips
The best oven repair is the one you never need. Regular maintenance significantly reduces breakdowns and extends the life of your appliance.
- Clean After Every Use
Grease and food debris damage oven components over time. Regular cleaning prevents build-up from reaching the heating element and other sensitive parts.
- Check And Replace Door Seals
Run your hand around the oven door while it is warm. If you can feel heat escaping, the seal needs replacing. It’s a low-cost fix that immediately improves efficiency.
- Don’t Slam The Door
Repeated impact damages hinges and causes the door to misalign over time. Close the oven gently — and encourage everyone in the household to do the same.
- Watch For Performance Changes
If cooking times increase or food results change noticeably, don’t ignore it. Early diagnosis is almost always cheaper than waiting for a full breakdown.
- Don’t Line The Base With Foil
Placing foil on the oven floor blocks ventilation and can cause serious overheating damage. Use a proper oven liner if you want to protect the base.
- Book An Annual Professional Check
A yearly inspection by a qualified engineer catches worn components before they fail. Our appliance repair service covers all major brands across London.
Common Faults By Oven Brand
All oven brands can develop the faults described above, but certain models are known for specific recurring issues. Here is what we see most often.
