Oven Not Heating Up - Common Causes Eastleigh Homeowners Should Know

Published July 2026 | Oven Not Heating Up Common Causes

We asked our Appliance Repair engineers the questions Eastleigh homeowners ask most. If your oven has stopped heating or won't reach the right temperature, here is what our team finds at the root of it - and what you can realistically do about it.

Why has my oven suddenly stopped heating up?

An oven that won't heat is one of the most common call-outs we take from Eastleigh residents, and the causes range from something as simple as a tripped circuit breaker to a failed heating element or a faulty thermostat. Before any physical inspection, our engineers check whether the oven is actually getting power at all. Sometimes the fault is upstream - a blown fuse in the consumer unit, a loose connection at the cooker's terminal block, or a tripped RCD. If the oven powers on, the clock works and the controls respond but it won't heat, that already narrows the field considerably.

In electric ovens - which account for the large majority of ovens in Hampshire homes - the most likely culprits are a burned-out bake element, a failed fan element, or a thermostat that has drifted out of calibration. In gas ovens, the igniter and gas valve are the components we replace most often. One useful clue before you even call anyone: if your oven heats from the grill but not the base, or vice versa, that points directly at a specific element rather than a wiring or control board issue. That distinction saves diagnostic time and usually means a faster, cheaper repair.

How do I know if the heating element has failed?

The heating element - or elements, since most fan ovens have both a bake element and a fan element - are among the most commonly replaced parts in domestic ovens. Brands like Hotpoint, Beko and Bosch all use variants of the same resistive heating technology, and over time those elements fatigue and eventually break. Visually, a failed element sometimes shows obvious signs: a burn mark, a split in the metal casing, or a blistered area where the element has arced. But not always. Some elements fail internally without any visible damage at all, and in those cases an engineer will test continuity using a multimeter. An open-circuit reading confirms the element is gone.

Common signs your element has failed include the oven running but staying cold or barely warm, an unexplained burning smell without an obvious source, food taking significantly longer than it should to cook through, or the element glowing orange in patches rather than evenly along its full length. Replacing a heating element in most freestanding electric ovens typically costs between 80 and 180 pounds including parts and labour, depending on the model. For built-in ovens from premium brands like Neff or Siemens, that can rise to 200 pounds or more. Always check whether the appliance is still under warranty first - some manufacturers cover parts for up to five years.

What does a faulty oven thermostat look like in practice?

A thermostat that has failed or drifted out of calibration is subtler than a broken element. The oven heats up - sometimes quite enthusiastically - but it can't regulate that heat accurately. What you typically see in practice is one of two patterns. In the first, the oven overheats: you set it to 180 degrees Celsius and food is burning well before the recipe time is up. This happens when the thermostat sensor has failed in an open state, leaving the oven with no way of knowing it has reached temperature, so it keeps heating without cutting back.

In the second pattern, the oven underheats consistently. You set it to 200 degrees and it never actually gets there, or cycles off too early. This often means the sensor is reading a false high temperature and telling the control circuit to cut power before the cavity is properly up to heat. Our engineers often use the Voltrade GoFIX diagnostic tool to pull stored fault codes from digital ovens before starting any physical inspection - on newer models this cuts diagnostic time significantly. On older analogue thermostats, the test is more hands-on: a thermocouple probe and a separate oven thermometer placed inside the cavity tells us what the oven is actually doing versus what it thinks it is doing. Thermostat replacement typically runs between 100 and 200 pounds including labour.

Could the fan be causing my oven's heating problem?

Fan-assisted ovens circulate hot air around the cavity to cook food more evenly and reduce hot spots. The fan itself doesn't generate heat - that is the element's job - but a failed fan motor can make a perfectly functional oven behave as though it is barely heating. Here is why: in a fan oven, the ring-shaped fan element at the back works in tandem with the fan blade. If the fan motor seizes or the blade is obstructed, heat concentrates at the rear of the oven instead of circulating. The oven may well reach temperature at the sensor location - which is also typically at the back - but the front and centre of the cavity stay cold. Food placed on the middle shelf comes out undercooked on the side nearest the door.

Signs the fan motor is failing include a loud rattling or grinding noise during cooking, the fan running slowly or intermittently, noticeably uneven cooking results even when the indicator light confirms the oven has reached temperature, or the fan not running at all (you can often check this by looking through the door glass with the oven switched on). Fan motor replacements typically cost between 90 and 160 pounds. Beko and Hotpoint models tend to have relatively accessible fan assemblies. Some integrated Bosch or Siemens ovens require more disassembly to reach the motor, which can push labour time - and therefore cost - a little higher.

When does the control board need replacing?

The control board - sometimes called the PCB or electronic programmer - is the brain of a modern oven. It manages everything from the clock display to the temperature regulation logic, and when it fails the symptoms can be confusing because they often mimic other faults. Control board failure is actually less common than element or thermostat failure, but it does happen - particularly in ovens that have experienced a power surge or been exposed to moisture. Some of the Eastleigh call-outs we attend involve ovens where a hob pan has boiled over repeatedly and liquid has tracked down into the electronics behind the fascia panel.

Signs that point toward a control board problem rather than a simpler component fault include the oven behaving inconsistently (heating sometimes but not others), the display showing error codes that don't clear after a reset, certain functions working while others don't - for example, the grill working but fan-assisted mode not - or the oven cutting out mid-cook without an obvious trigger. Control board replacement is typically the most expensive oven repair. Parts alone can cost between 80 and 250 pounds depending on make and model, with labour on top. For older ovens - anything over eight to ten years old - the cost of a new control board sometimes makes replacement the more sensible route. Our engineers will always tell you if that is the case.

Is it safe to keep using an oven that won't heat properly?

This is a question we hear regularly from Eastleigh homeowners trying to get through to the weekend or manage a busy school week. The answer depends on the type of oven and the nature of the fault. For an electric oven with a failed element, the immediate safety risk is relatively low - the oven won't be reaching dangerous temperatures. However, if the element has cracked and is still drawing current, there is a risk of arcing, which can trip the consumer unit repeatedly or in rare cases cause a more serious electrical fault. Our advice is to use another cooking method until it is repaired.

For a gas oven that won't ignite or heat properly, the position is more serious. If the oven is failing to light reliably, unburned gas can accumulate inside the cavity or inside adjacent kitchen cabinetry. If you can smell gas when using the oven - or at any point - turn the appliance off at the isolation valve, ventilate the kitchen thoroughly, and call for repair before using it again. Beyond immediate safety, there is also a food safety consideration that applies to both electric and gas ovens: using an oven that doesn't reach the correct temperature means high-risk foods like poultry may not reach the internal temperatures needed to kill harmful bacteria. This is a real hazard, not a theoretical one. Our engineers can typically attend addresses across Eastleigh and the wider Hampshire area within one to two business days in most cases.

How much should I expect to pay for an oven repair in Eastleigh?

Repair costs vary depending on the fault, the brand, and the age of the appliance. Here is a realistic breakdown of what our engineers typically charge in the Hampshire area:

• Heating element replacement: 80 to 180 pounds
• Thermostat replacement: 100 to 200 pounds
• Fan motor replacement: 90 to 160 pounds
• Control board replacement: 150 to 350 pounds
• Call-out and diagnosis only: 50 to 80 pounds (typically credited against the repair if you proceed)

Labour rates in the Eastleigh area generally sit in the range of 50 to 80 pounds per hour. Most element and thermostat replacements take between one and two hours. Control board replacements can take longer, particularly on built-in ovens where accessing the electronics requires removing the appliance from its housing. Parts availability is another factor worth knowing about. Common Hotpoint and Beko components are usually in stock with next-day delivery as standard. For older or less common models - some older Samsung and LG integrated ovens, for example - parts may need to come from a specialist supplier, which can add a few days to the overall turnaround.

Can I fix an oven heating problem myself?

Some oven repairs are within reach of a competent DIYer, but there are important limits. On the electric side, replacing a heating element is a job many homeowners can manage safely if they work carefully. The key steps are:

1. Disconnect the oven from the power supply - do not just switch it off at the wall, unplug it or isolate it at the consumer unit.
2. Allow the oven to cool completely before accessing the element terminals or opening the back panel.
3. Photograph the wiring before disconnecting anything.
4. Find the correct replacement part using the model number, which is usually on a label inside the oven door frame or on the side wall of the cavity.
5. Replace like for like - using the exact element specified for your model, not a generic equivalent.

However, do not attempt DIY work on a gas oven. In the UK, any work on gas appliances must be carried out by a Gas Safe registered engineer. This is a legal requirement, not simply a recommendation. If your gas oven won't heat, book a qualified engineer. For electric ovens, if you are not comfortable working around appliance wiring even with the power fully isolated, call a professional. A mistake during reassembly can create a live fault that is not immediately obvious but becomes dangerous under load.

When does it make more sense to replace the oven than repair it?

This is a question our engineers across Eastleigh and the wider Hampshire area are regularly asked, and the answer comes down to three things: the age of the appliance, the cost of the repair, and the availability of parts. As a general guide, if the oven is more than ten years old and the repair cost exceeds half the price of a comparable replacement, buying new often makes more financial sense. This is particularly true for control board faults on older appliances, where a 250 pound repair bill on a 12-year-old cooker is hard to justify.

At the other end of the scale, a three-year-old Bosch or Siemens built-in oven with a failed heating element is absolutely worth repairing. The element costs around 30 to 60 pounds as a part, and the oven has years of useful life ahead of it. Factors that favour repair include the oven being less than seven or eight years old, a clearly identified single-component fault, readily available parts, and the oven being integrated into cabinetry where replacement would mean fitting costs on top. Factors that favour replacement include multiple components failing, the manufacturer no longer supporting the model with spare parts, or the repair cost coming close to 50 to 60 percent of what a replacement would cost.

What should I tell the engineer when I book a repair?

The more useful detail you can provide when you book, the better prepared the engineer will be - and on many Eastleigh jobs, that preparation is the difference between a repair completed on the first visit and one that needs a second call to collect parts. Here is what actually makes a difference:

• The make and model number (on a label inside the oven door, usually on the frame or side wall of the cavity)
• Whether it is a freestanding cooker, a built-in oven, or a range-style appliance
• Whether it is electric, gas, or dual fuel
• A specific description of the fault - for example, "heats from the grill but not the base" or "reaches temperature then cuts out after about 15 minutes"
• Any error codes showing on the display
• Approximately how old the appliance is and whether it is still under warranty
• Whether anyone has already looked at it or attempted a repair

This information lets the engineer come to your address with the most likely replacement parts already in the van. Combined with the Voltrade GoFIX pre-visit diagnostic, which lets our team identify common fault patterns before arriving, this approach significantly reduces the chance of a wasted journey.

Most oven heating faults come down to a small number of parts - elements, thermostats, fan motors and occasionally control boards. With the right diagnosis, the large majority of these repairs can be completed cleanly in a single visit. If you're in Eastleigh or elsewhere in Hampshire and your oven has stopped heating, getting an accurate description of the fault before you call will save you time and typically money too.

Frequently Asked Questions

Why is my oven not reaching the temperature I set?

The most common reasons an oven won't reach the set temperature are a failing thermostat or a partially functioning heating element. A thermostat that reads incorrectly can cause the oven to cut off heat too early, while a deteriorating element may heat unevenly or not at full power. A qualified engineer can test both components quickly and confirm which is at fault.

Can a power cut cause an oven to stop heating?

Yes, in some cases. A power surge or sudden cut can trip the RCD in your consumer unit or, on ovens with electronic controls, corrupt the programmer's settings. After a power event, try resetting the oven by isolating it at the consumer unit for 30 seconds and then restoring power. If it still won't heat correctly, the control board may need professional attention.

How long does an oven heating element typically last?

In normal use, a heating element in a domestic oven typically lasts between five and ten years, though this varies by how frequently the oven is used and at what temperatures. High-heat roasting and frequent self-clean cycles place more stress on elements and can shorten their lifespan. Replacing an element before it fails completely can prevent secondary damage to surrounding wiring.

Is it worth repairing a Beko or Hotpoint oven rather than replacing it?

For most Beko and Hotpoint ovens under eight years old, repair is usually worth doing. Both brands have good parts availability across the UK, which keeps repair costs reasonable. A typical element or thermostat repair will cost considerably less than a replacement appliance and will commonly restore full performance. The calculation changes if the oven is older or the fault is in the control board.
