Oven Not Heating Up in Newcastle - Common Causes and What to Do

Published August 2026 | Oven Not Heating Up

What Causes an Oven to Stop Heating Up

When an oven stops heating, there are several components that could be responsible. The cause varies depending on whether you have an electric or gas oven, how old the appliance is, and how heavily it's used. Our engineers in Newcastle see the same faults come up time and again, so it's worth knowing what you're likely dealing with before anything else.

Failed Heating Element (Electric Ovens)

The heating element is the most common culprit in electric ovens. Most electric ovens have two elements - a bake element at the bottom and a grill element at the top. When one burns out, you'll notice uneven cooking or no heat at all depending on which one fails. A visually damaged element often shows blistering, cracks, or a burn mark. Brands like Hotpoint, Beko, and Bosch all use slightly different element configurations, but the failure mode is broadly the same across the board.

Faulty Thermostat

The thermostat regulates temperature by telling the oven when to apply and cut heat. When it fails, the oven may not reach the set temperature, overshoot it wildly, or not switch on at all. A thermostat fault is trickier to spot visually - you'll usually notice it through inconsistent cooking results before the oven stops heating entirely. This is a very common fault our engineers see in older electric ovens across Tyne and Wear.

Broken Igniter (Gas Ovens)

In gas ovens, the igniter opens the gas valve and creates the spark to light the burner. A weak or failed igniter is the most common reason a gas oven won't heat. You might hear the click of the spark but the burner never lights, or the oven takes a long time to ignite. Samsung and LG gas ranges tend to develop igniter faults after several years of regular use, and replacements are widely available.

Blown Thermal Fuse or Safety Cut-Out

Most modern ovens have a thermal fuse - a safety device designed to cut power if the oven overheats. Once it blows, it won't reset itself and the oven won't heat at all. This can feel like a total electrical failure, but the rest of the oven's display and functions may still work normally. It's a cheap part but requires the oven to be dismantled to access it safely.

Faulty Fan Motor (Fan-Assisted Ovens)

Fan ovens use a motor to circulate hot air around the cavity. If the fan motor fails, you'll often still get some heat but cooking will be very uneven and the oven won't reach temperature properly. In some models, the oven won't operate at all without the fan running. This is a moderately common fault in Bosch and Hotpoint fan ovens that have done several years of daily cooking.

Faulty Control Board or Selector Switch

The control board is the brain of a modern electric oven. If it fails, the oven might not respond to any inputs or fail to switch on heat circuits even when everything else appears functional. Selector switch faults are more mechanical - the physical switch that controls which heating mode is active can wear out or burn internally. These faults are less common but more expensive to fix.

Gas Supply Problems

This one is easy to overlook. If your gas oven won't light at all, always check whether other gas appliances in the house are working. A closed isolation valve, an empty prepayment meter, or a wider supply interruption from your provider could be the cause. It's worth eliminating the obvious before calling anyone out.

How to Diagnose the Problem Yourself

Before calling an engineer, there are several checks you can do safely at home. These won't require any tools or technical knowledge, and they can save you time and money by narrowing down the fault.

1. Check the basics first. Make sure the oven is properly plugged in (for electric models) or that the gas supply is turned on. Check your fuse box for any tripped breakers. This sounds obvious but our engineers in Newcastle find this is the cause more often than you'd expect.
2. Look at the heating element visually. Open the oven door and inspect the bake element at the bottom and the grill element at the top. Any visible damage - burn marks, blistering, visible breaks in the element - points directly to an element failure.
3. Run the grill independently. If your oven has a separate grill function, try running just the grill. If that heats but the main oven doesn't, the bake element or thermostat is likely the problem. If neither heats, you may have a control issue or a blown fuse.
4. Test with an oven thermometer. If the oven turns on but doesn't reach the right temperature, put an oven thermometer inside and set the oven to 180 degrees Celsius. Leave it for 20 minutes and check how close the actual temperature is. A big discrepancy often points to a thermostat fault.
5. Listen for the igniter click (gas ovens). When you try to light a gas oven, you should hear rapid clicking. If you hear the click but see no flame, the igniter is likely weak or the gas valve isn't opening. If there's no click at all, the ignition system itself has failed.
6. Use the Voltrade GoFIX diagnostic tool. If you're not sure what you're dealing with, the Voltrade GoFIX tool can walk you through a guided fault diagnosis based on your specific oven model and the symptoms you're seeing. It's a good way to arrive at a probable cause before booking an engineer.
7. Check error codes. Many modern ovens from brands like Bosch, Samsung, and LG display error codes when something goes wrong. Note down any codes showing on the display - an engineer can use these to pinpoint the fault much faster.

DIY Fixes vs When to Call a Professional

There's a real difference between what a confident DIYer can safely tackle and what should be left to a qualified appliance engineer. Getting this judgement right matters both for your safety and for not making the repair more expensive than it needs to be.

What you can reasonably do yourself

Replacing a heating element in an electric oven is within reach for most people who are comfortable with basic DIY. Elements are widely available online for popular models - a replacement element for a Hotpoint or Beko oven typically costs between 15 and 40 pounds. The process involves isolating the power at the fuse box, removing a few screws, disconnecting the spade connectors, and fitting the new element. That said, you must be completely certain the power is isolated before starting, and you need to be confident the replacement part is correct for your specific model.

Cleaning the igniter electrodes on a gas hob is also something you can do yourself - grease build-up around the electrode can prevent it from sparking properly. But this is different from replacing an igniter inside a gas oven, which involves working near the gas valve and burner assembly.

When to call an engineer

Any fault involving gas - including a failed oven igniter, a faulty gas valve, or anything connected to the gas supply - must be handled by a qualified engineer. This isn't overly cautious advice; working incorrectly on gas appliances is genuinely dangerous and illegal without the right qualifications. All gas work in a domestic setting must be carried out by a Gas Safe registered engineer.

Thermostat replacements, thermal fuse replacements, control board faults, and fan motor failures are also best left to professionals. These repairs require the oven to be partially dismantled, and there's a real risk of damaging other components if you're not familiar with the appliance's internals. In Newcastle and across Tyne and Wear, a qualified engineer can typically diagnose and fix these faults in a single visit.

What a Qualified Appliance Engineer Will Do

When our engineers attend an oven repair in Newcastle, the first thing they do is a structured diagnostic. This means checking the fault symptoms against the appliance's service history (if available), running through a methodical test of each circuit, and using a multimeter to check components for continuity and resistance. This is faster and more accurate than guesswork.

For an electric oven, the engineer will test the heating elements, thermostat, and thermal fuse in sequence. For a gas oven, they'll check the igniter resistance, inspect the gas valve operation, and verify the burner is functioning correctly. Most faults can be confirmed within 20 to 30 minutes of starting the diagnostic.

Once the fault is confirmed, the engineer will quote for the repair before doing anything. If it's a common part like an element or igniter, many engineers carry these in their van for popular brands like Hotpoint, Beko, and Bosch - meaning the repair can often be completed on the same visit. Less common parts for premium brands may need to be ordered, adding a day or two to the process.

After the repair, a good engineer will always run the oven through a full heat cycle to confirm it's working correctly before leaving. They should also check that there are no other obvious faults developing that might cause problems in the near future.

Costs and What Affects the Price

Oven repair costs in Newcastle are broadly in line with the UK average. Here's what you can typically expect to pay for the most common repairs in 2026.

A call-out and diagnostic fee typically runs between 50 and 80 pounds. Some engineers apply this fee to the final repair cost if work goes ahead; others charge it separately. It's worth asking upfront.

Replacing a heating element including parts and labour typically costs between 80 and 150 pounds, depending on the brand and element type. Beko and Hotpoint elements tend to be at the lower end; branded Bosch elements can push the higher end.

A thermostat replacement including parts and labour commonly falls between 90 and 160 pounds. The thermostat itself can vary significantly in cost depending on the model.

A gas oven igniter replacement typically comes in between 80 and 150 pounds all in. If the gas valve also needs replacing, expect to add another 60 to 100 pounds.

Fan motor replacements typically cost between 100 and 180 pounds. Control board replacements are the most expensive common repair, often running between 150 and 300 pounds depending on the appliance - at that point it's worth comparing the repair cost against the value of the oven.

What affects the price most significantly is the brand and age of the appliance. Parts for premium brands like Bosch can cost two to three times more than equivalent parts for Beko or Hotpoint. Older appliances can also be harder to source parts for, adding time and cost to the repair. In Tyne and Wear, getting a fixed-price quote before work begins is always recommended.

How to Prevent Oven Heating Problems in Future

Most oven heating faults don't appear overnight - they develop gradually through wear, grease build-up, and thermal stress. A few habits can significantly reduce the chance of a breakdown.

Keep the oven clean. Grease and food residue that builds up around heating elements and igniters is one of the most common causes of premature failure. Use the self-clean function if your oven has one, or wipe the interior down regularly with a suitable oven cleaner. Avoid getting cleaning products directly on the elements themselves.

Don't line the bottom of the oven with foil. It restricts airflow, can damage the lower element, and interferes with heat distribution in fan ovens.

Check the door seal periodically. A damaged or worn door seal lets heat escape, which forces the oven to work harder and puts additional stress on the thermostat and heating elements. Replacement seals for most popular brands are inexpensive and easy to fit.

Avoid slamming the oven door. It's one of those things that seems harmless but gradually loosens hinges, damages the seal, and can stress internal components over time.

If your oven is more than ten years old, it's worth having it checked over by an engineer even if it seems to be working fine. Components wear out, and catching a deteriorating thermostat or a cracking element early is much cheaper than dealing with a full breakdown.

Frequently Asked Questions

Why is my oven not heating up but the light still works?

If the oven light works but the oven won't heat, the electrical supply to the appliance is fine - the fault is in the heating circuit itself. The most likely causes are a failed heating element, a blown thermal fuse, or a faulty thermostat. A qualified engineer can confirm which component has failed using a multimeter to test for continuity in each part.

Can I still use my oven if only one element has failed?

Technically yes, but it's not ideal. If the bake element has failed, you may still be able to use the grill function. If the grill element has gone, you can use conventional heat from the base. Cooking results will be inconsistent and times will be unpredictable. It's better to get the element replaced promptly - it's one of the cheaper repairs and restores the oven to full working order quickly.

How long does an oven repair typically take in Newcastle?

For common faults like element or igniter replacements, most repairs are completed in a single visit lasting one to two hours. If a part needs to be ordered - which is more likely for less common brands or older models - you may be without the oven for two to five days. Our engineers aim to carry stock of the most frequently needed parts for popular brands like Hotpoint, Beko, and Bosch to keep first-visit fix rates high across Newcastle and the wider Tyne and Wear area.

Is it worth repairing an old oven or should I just replace it?

A useful rule of thumb is to avoid spending more than half the cost of a comparable new appliance on a repair. If your oven is under eight years old and the fault is a standard component like an element, thermostat, or igniter, repair almost always makes financial sense. If the control board has failed in an older premium oven, the maths gets closer. An honest engineer will tell you if the repair isn't worth it rather than push you into unnecessary work.

Do I need a Gas Safe engineer to fix a gas oven in Newcastle?

Yes. Any work that involves the gas components of an oven - the igniter, gas valve, burner, or gas connection - must be carried out by a Gas Safe registered engineer. This is a legal requirement in the UK, not just a recommendation. You can verify an engineer's Gas Safe registration on the official Gas Safe Register website before booking. All Voltrade engineers working on gas appliances across Newcastle and Tyne and Wear hold the appropriate Gas Safe qualifications.
