Oven Not Heating Up in Storrington - Common Causes and How to Fix It

Published August 2026 | Oven Not Heating Up Common Causes

You've set the oven to 180 degrees, left it to preheat, and come back to find the interior barely warm. The light's on, the display is showing the right temperature, but there's clearly no heat building up inside the cavity. If you're based in Storrington or the surrounding villages in West Sussex, you're not alone - this is one of the most common appliance faults our engineers are called out to across the area.

Understanding What's Actually Going Wrong

When an oven stops heating properly, it's tempting to assume the worst and start pricing up replacements. In most cases, that's not necessary. Electric ovens and gas ovens each rely on different heating mechanisms, and a failure in any one of several components can leave you with an appliance that looks like it's working but isn't producing any usable heat.

For electric ovens - which covers most built-in and freestanding models from brands like Bosch, Hotpoint, Beko and Samsung - the heat comes from one or two resistive elements. A main bake element typically sits at the base of the cavity, while fan-assisted models also have a circular element around the rear fan. When electricity passes through these elements, they heat up. If either one fails, heat output drops or disappears entirely.

Gas ovens work on a different principle entirely. They rely on a burner ignited either by a spark igniter or, in older models, a standing pilot light. A very common failure point in modern gas ovens is the igniter itself - it controls not just the spark but also the safety valve that allows gas to flow. Understanding which type of oven you have is the essential first step. Once you know that, you can work through the most likely causes systematically.

The Most Common Causes of an Oven Not Heating Up

A Failed Heating Element

This is the number one cause of a dead electric oven, and our engineers see it regularly in Storrington homes. The bake element - that thick coil running along the bottom of the oven cavity - can burn out gradually or fail abruptly after years of use. When it fails, you'll often see visible signs: a crack, a blister, or a dark burn mark on the element. Sometimes it breaks cleanly with no obvious damage at all, which makes diagnosis slightly trickier.

Tell-tale signs include: the oven taking far longer than normal to reach temperature, food browning on top but remaining undercooked at the base, or the oven not heating at all despite the fan running normally. Replacing a bake element is one of the more affordable repairs - parts for common models including Hotpoint, Beko, and older Bosch appliances typically cost between 15 and 40 pounds, and the job is usually done within an hour.

A Faulty Thermostat

The thermostat's job is to regulate the internal temperature. It reads the heat level inside the cavity and signals the heating element to switch on or off to maintain whatever temperature you've dialled in. When the thermostat fails, one of two things commonly happens: the oven either doesn't heat at all, or it heats without stopping and gets dangerously hot.

A failing thermostat is harder to spot without testing equipment because there's often no visible sign of the fault. Our engineers use the Voltrade GoFIX diagnostic tool to identify thermostat faults accurately - it removes the guesswork and avoids unnecessary part replacements. A replacement thermostat for most standard models typically costs between 30 and 80 pounds for the part alone, with labour on top.

A Broken Igniter in Gas Ovens

If you have a gas oven that clicks repeatedly but won't light - or doesn't click at all - the igniter is commonly the cause. Modern gas oven igniters serve a dual function: they produce the spark and they draw enough current to open the gas safety valve. If the igniter is weak or has partially failed, it may not draw sufficient current to trigger that valve, which means no gas flows and the burner never lights.

This is a repair that must always be handled by a qualified professional. In the UK, any work involving gas components on an appliance must be carried out by a Gas Safe registered engineer - this is a legal requirement, not a suggestion. Don't attempt to replace a gas igniter yourself, regardless of what online guides suggest.

A Failed Temperature Sensor or Probe

A temperature sensor failure is increasingly common in newer appliances. Modern ovens from LG, Samsung, and Bosch - particularly models from the last five to ten years - use an electronic temperature probe rather than a traditional mechanical thermostat. This probe, usually a slim metal rod extending into the oven cavity, measures the internal temperature and sends readings to the control board in real time.

When the probe fails or drifts out of calibration, the control system can believe the oven has already reached temperature when it hasn't. The result is an oven that technically operates - fans run, lights work, display shows the target temperature - but never actually gets hot enough to cook. Temperature sensor probes typically cost between 15 and 50 pounds to replace, making this a relatively affordable fix when caught early.

Problems with the Control Board

The control board is the electronic brain of a modern oven. It processes inputs from the temperature sensor, interprets your settings, and instructs the heating elements when to activate. If the board develops a fault - which can happen following a power surge, for example - the oven may stop heating entirely, throw up error codes, or behave unpredictably from session to session.

Control board replacement is one of the more expensive oven repairs. Depending on the brand and model, a replacement board can cost anywhere from 80 to 200 pounds or more for the part, and for older or budget-end appliances, the repair may not make financial sense when weighed against the cost of a new oven.

A Blown Thermal Fuse

Many ovens include a thermal fuse as a built-in safety device. If the oven overheats for any reason - a failing thermostat, a blocked fan, a fault in the control circuit - this fuse blows to cut the power before damage or fire can occur. Once it has blown, the oven won't heat at all, even if every other component is working perfectly.

Thermal fuses are inexpensive parts, typically under 10 pounds, but replacing the fuse without identifying why it blew in the first place is a mistake. If the underlying cause isn't fixed, the replacement fuse will blow again - sometimes very quickly.

Solutions That Actually Work

Some faults can be tackled safely at home. Others require a professional. Here's a realistic breakdown of where the line sits.

Things you can try yourself before calling an engineer:

1. Check the circuit breaker. If the oven has completely stopped working with no lights or display, go straight to your fuse board. A tripped breaker is occasionally the only issue, and resetting it takes seconds.
2. Run a visual inspection of the element. Open the oven and look carefully at the lower element. Cracks, blisters, or dark burn marks confirm it has failed. Always disconnect the oven from the mains before touching anything inside.
3. Check your oven settings. Some modern models have a child lock or a demo mode that prevents heating while keeping the display active. Check your manual or search your model number online to rule this out - it catches people out more often than you'd think.
4. Allow a proper preheat. Many fan-assisted ovens need 15 to 20 minutes to reach operating temperature accurately. If you're loading food immediately after switching on, that alone can cause disappointing results.
5. Use an oven thermometer. Available for under 10 pounds from most hardware shops, an oven thermometer tells you whether the actual cavity temperature matches the displayed setting. If there's a significant gap, you have a thermostat or sensor issue worth investigating further.

What should always go to a professional: any gas oven fault, any wiring issue, control board faults, and any situation where you've ruled out the obvious causes but the oven still won't heat.

When You Need a Professional vs. Sorting It Yourself

A fair number of oven faults in Storrington homes come down to a single failed component that's accessible and replaceable. If you're comfortable with basic DIY work and confident the oven is fully disconnected from the power supply, replacing a bake element on a Hotpoint or Beko is something many homeowners manage safely at home.

That said, there are clear situations where you should call an engineer without hesitation:

Gas ovens - always call a professional. Gas Safe registration is a legal requirement in the UK for any work involving gas components. This applies to oven igniters, burners, and gas valves. There's no workaround, and it's not worth the risk.

Any sign of burning around wiring or connectors. If you notice scorching, melted plastic, or a burning smell near the terminal block or internal wiring, stop using the oven immediately and don't reconnect it until an engineer has assessed it.

Uncertain diagnosis. If the element looks fine but the oven still won't heat, you're likely dealing with a thermostat, sensor, or control board fault. These components require proper testing equipment to diagnose reliably. Our engineers use the Voltrade GoFIX system to run accurate diagnostics and identify faults without expensive trial and error, which saves both time and money on unnecessary parts.

Repeated failures. If the same component keeps failing on the same oven, that's a signal that something else is driving the fault. An experienced engineer will look beyond the obvious to find the root cause.

What to Expect from a Repair Visit

If you're in Storrington or elsewhere in West Sussex and you book an engineer for an oven that won't heat, here's what a typical visit looks like from start to finish.

1. Initial assessment. The engineer will ask a few questions about when the problem started, whether there are any error codes on the display, and whether there's been any visible damage or unusual smells. This takes a few minutes and often narrows down the likely fault before the oven is even opened.
2. Diagnosis. Using a combination of visual checks and diagnostic equipment, the engineer will identify the failed component. For most common faults, this is typically completed within 20 to 30 minutes.
3. Quote. Before any parts are fitted, you'll receive a clear quote covering parts and labour. A good engineer will also give you an honest view of whether the repair is worth doing relative to the age and value of the appliance.
4. Repair. Most standard faults - element replacement, thermostat, temperature sensor - can be completed in a single visit when parts are available. Control board replacements sometimes require a return visit if the specific part needs to be ordered, which commonly takes two to five working days.

Typical repair costs across West Sussex:

• Heating element replacement: 80 to 150 pounds (parts and labour)
• Thermostat replacement: 100 to 180 pounds (parts and labour)
• Temperature sensor replacement: 80 to 140 pounds (parts and labour)
• Control board replacement: 150 to 300 pounds depending on model (parts and labour)

Premium brands like Bosch and Samsung tend to sit at the higher end of these ranges due to part costs. Budget brands like Beko and older Hotpoint models typically fall lower. These figures reflect what our engineers commonly encounter - they're estimates, not fixed prices, since every appliance is different.

Common Questions from Storrington Homeowners

How much does it typically cost to fix an oven that won't heat up in Storrington?

The cost depends on the fault and the oven model. A heating element replacement - the most common repair - typically costs between 80 and 150 pounds for parts and labour combined. Thermostat or temperature sensor faults tend to come in at 100 to 180 pounds. Control board replacements are at the higher end and can reach 250 to 300 pounds on newer premium models. Most engineers include the call-out and diagnostic assessment within the overall repair cost, so you know the fault before committing to anything.

Is it worth repairing my oven or should I just replace it?

A commonly used rule of thumb is this: if the repair cost exceeds 50 percent of what a comparable new appliance would cost, replacement often makes more financial sense. For a mid-range oven priced around 400 to 600 pounds new, a repair under 200 pounds is commonly good value. For budget appliances or models over 10 years old, it's worth getting a proper diagnosis first - a 100-pound element replacement on an older Hotpoint can realistically buy you several more years of reliable use.

Can I use my oven safely if the heating element is visibly damaged?

No. A heating element that shows visible damage - cracks, blisters, burn marks, or any sign of arcing - should be treated as a live electrical hazard. Using the oven in this state risks a short circuit, arcing inside the cavity, or in serious cases, fire. Switch the oven off at the wall socket, leave it disconnected, and don't use it again until the element has been replaced by a qualified engineer. This applies equally to the main bake element and the fan element in fan-assisted models.

How long does an oven repair usually take in West Sussex?

Most standard repairs - heating element, thermostat, temperature sensor - are completed in a single visit lasting around one to two hours. Our engineers carry common parts for popular brands including Bosch, Hotpoint, Beko and LG, which means same-visit completion is common for straightforward faults. Control board replacements are the exception - if the specific board needs to be ordered in, a return visit is typically required within two to five working days of the initial diagnosis.
