Oven Not Heating Up - Common Causes and Repairs for Littlehampton Homes

Published August 2026 | Oven Not Heating Up Common Causes

A homeowner in Littlehampton slid a tray of roast vegetables into their Hotpoint fan oven on a Sunday afternoon, set the temperature to 200 degrees Celsius, and left it to get on with dinner. An hour later, the tray came out barely warm - the fan had been running, the oven light was on, and the display showed the correct temperature, but the actual heat just wasn't there. They turned it off and on again, checked the controls, even tried a different shelf position. Nothing changed. When our engineer arrived the following morning, it took less than five minutes to understand what had gone wrong - and it's a fault we see regularly across West Sussex.

What Was Actually Going On

A failed lower heating element is the single most common reason electric ovens stop heating properly - and it's exactly what our engineer found when he opened up this Hotpoint. Electric ovens typically run two separate elements: a lower bake element, usually concealed beneath the oven floor, and an upper grill element visible at the top of the cavity. When the lower element fails, the oven powers on normally - lights work, fan runs, controls respond - but the cavity never reaches cooking temperature.

In this case, the element had developed a clean break near one of its terminal connections. This type of failure is thermal fatigue: repeated heating and cooling cycles over years of use eventually crack the element's metal casing. The Hotpoint in question was just over seven years old, which puts it squarely in the window where these failures start appearing. Our engineer used the Voltrade GoFIX diagnostic tool to check the element's resistance - a failed element typically reads open circuit where it should show a resistance in the range of 20 to 30 ohms. The reading confirmed it: complete failure.

But a broken element isn't the only thing that stops an oven from heating. Here are the faults our engineers encounter most often when a Littlehampton household calls about an oven that won't get hot:

• Failed heating element - as described above, most common in electric ovens over five years old. Often shows as no heat at all, or only partial heating if just one of the two elements has gone.
• Faulty thermostat - the oven may heat, but inconsistently. Food burns on the outside while remaining undercooked inside, or the oven never reaches the set temperature. The thermostat controls the cycling of heat; when it fails it either stays open (no heat) or closed (constant, uncontrolled heat).
• Broken temperature sensor (thermistor) - the thermistor tells the control board what temperature the oven cavity is actually at. A faulty sensor sends incorrect data, causing the oven to under-heat or shut off prematurely. Sensors are relatively inexpensive components but commonly overlooked.
• Failed igniter (gas ovens) - in a gas oven, the igniter has to reach a specific temperature to open the gas valve. When it weakens, the oven either doesn't light at all or takes several attempts. If your Beko or Samsung gas range is slow to ignite or won't light consistently, the igniter is the first thing to check.
• Blown internal fuse - a power surge can blow the fuse on the oven's control circuit. The oven appears dead or only partially functional. Common in older models without surge protection.
• Faulty control board - less common but possible in newer digitally controlled ovens from brands like Bosch or LG. A damaged control board can cause erratic behaviour, error codes, or a complete failure to heat.
• Damaged door seal - easy to overlook, but a worn or torn door seal allows heat to escape continuously. The oven heats, but never efficiently, and food takes far longer than it should.

For this particular Littlehampton job, the diagnosis was clean: failed lower bake element, no secondary faults detected.

How the Problem Was Resolved

Replacing a heating element is a repair that follows a consistent set of steps. Our engineer completed the whole job in a single visit, which is typically possible when parts are in stock or readily available for common models.

The process went like this:

1. Disconnect power - always the first step before touching any internal oven components. Never attempt to access internal parts with the oven connected to the mains.
2. Remove the oven shelves and floor panel - in most Hotpoint models, the floor panel lifts out once the shelves are removed, giving access to the lower element connections.
3. Unscrew the element and disconnect the terminals - the element is typically held by two or three screws at the back of the oven cavity. The terminal connections are push-fit in most models.
4. Test the old element - confirming open circuit before fitting the replacement, so the fault is properly documented.
5. Fit the new element - the replacement was a direct-fit Hotpoint-compatible part. Terminals reconnected, screws tightened, floor panel and shelves replaced.
6. Test at temperature - the engineer ran the oven to 180 degrees and monitored it for 15 minutes, verifying the element was drawing current and the cavity was reaching temperature correctly.

The whole job took approximately 55 minutes from arrival to pack-up. The homeowner had a fully functioning oven before lunch.

One thing worth noting: our engineer also checked the door seal while he was there - it's a quick visual check that costs nothing - and found it was in good condition. Had it been damaged, he would have replaced it at the same time to avoid a return visit. This kind of opportunistic checking is standard practice when our engineers are already on site.

What This Cost and How Long It Took

The total cost for this repair in Littlehampton came to 145 pounds, which included the call-out, the replacement element (a genuine-compatible part for the Hotpoint model), and the labour. The part was available same-day from a local appliance parts supplier, so there was no delay between diagnosis and fix.

For context, here are typical price ranges for the most common oven heating faults:

• Heating element replacement (electric oven) - typically between 100 and 160 pounds including parts and labour
• Thermostat replacement - typically between 120 and 200 pounds depending on the model
• Temperature sensor replacement - typically between 80 and 140 pounds
• Gas igniter replacement - typically between 110 and 190 pounds, though gas work must always be carried out by a Gas Safe registered engineer
• Control board replacement - typically between 180 and 350 pounds, depending on the brand and parts availability. Bosch and LG boards tend to sit at the higher end
• Door seal replacement - typically between 60 and 110 pounds, and often worth doing at the same time when an engineer is already on site

Repair times vary, but most element and sensor replacements are completed in a single visit of under 90 minutes. Thermostat and control board faults sometimes require parts to be ordered, which can add one to two working days.

As a general guide: if the repair cost is going to exceed around 50 to 60 per cent of the replacement cost of the oven, it's worth weighing up whether a new appliance makes more sense. For a mid-range oven costing between 400 and 600 pounds, a repair in the 120 to 200 pound range is almost always the more economical choice.

How to Spot the Same Issue in Your Home

Knowing what to look for can help you describe the problem accurately when you call for a repair - and it can stop a minor fault from becoming a much worse one.

Signs your heating element may have failed:

• The oven light, fan, and display all work normally, but the cavity doesn't get hot
• Visible damage to the element itself - look through the oven glass or remove the shelves and check for cracks, blistering, or a burn mark on the element surface
• One shelf position cooks normally but another doesn't, which can indicate only one of the two elements has failed
• Food takes twice as long as it should even at the correct temperature setting

Signs of a thermostat problem:

• The oven runs but food is consistently undercooked or overcooked even at the correct setting
• The oven cycles off and doesn't return to temperature
• You've noticed the issue getting gradually worse rather than being a sudden failure

Signs of a temperature sensor fault:

• Error codes on the display, which is common on Bosch, Samsung, and LG models
• Oven shuts off before reaching the set temperature
• Temperature feels inconsistent from one cooking session to the next

Signs of a gas igniter issue:

• The igniter glows orange but the burner doesn't light
• Takes multiple attempts to ignite
• You can smell gas briefly but nothing catches - if this happens, ventilate the kitchen and don't attempt to use the oven again until it's been checked by a Gas Safe registered engineer

If you're in Littlehampton or the surrounding parts of West Sussex and you're seeing any of these symptoms, it's worth getting a diagnostic inspection rather than waiting. Small faults can escalate - a failing thermostat, for example, can eventually cause the control board to fail if left unchecked for long enough.

Lessons - What Every Littlehampton Homeowner Should Know

The repair described above was a simple one once the fault was identified. But this homeowner had been putting up with an oven that "wasn't quite right" for several weeks before the complete failure. There are a few things we'd want every Littlehampton household to take away from this kind of job.

Don't ignore gradual decline. An oven that takes longer than it used to, runs unevenly, or requires higher temperature settings to achieve the same results is probably developing a fault. Catching it early typically means a cheaper, faster repair.

Fan ovens and conventional ovens fail differently. In a fan-assisted electric oven, the fan continuing to run while the heat fails is a common presentation of element failure - the fan motor runs on a different circuit to the heating elements. Don't assume the oven is working because the fan is running.

Not all oven repairs require a manufacturer's part. Many common elements, thermostats, and sensors are available as compatible aftermarket parts at a fraction of the original manufacturer price - and for most domestic repairs they perform exactly as needed. Our engineers use quality-tested compatible parts where appropriate, which keeps costs down without compromising the repair.

Gas ovens need Gas Safe engineers. If you have a gas oven and suspect a fault with the burner, igniter, or any gas-carrying component, the repair must be carried out by a Gas Safe registered engineer. This is a legal requirement, not a suggestion - and it applies across Littlehampton and all of West Sussex. Don't ask a general handyman to look at a gas fault.

Regular maintenance extends appliance life. Keeping the door seal in good condition, clearing out debris from around the element, and avoiding slamming the oven door all help the appliance last longer. The number of element failures our engineers see that have been aggravated by physical damage suggests these basics are worth attending to.

Use a diagnostic tool when you're not sure. When the cause isn't immediately obvious from a visual check, running the Voltrade GoFIX diagnostic takes the guesswork out of identifying the fault. It means the right part is ordered first time, and the repair is completed in a single visit rather than two or three.

Related Questions

How long do oven heating elements typically last?

Most electric oven heating elements last between 5 and 10 years under regular domestic use. Ovens used heavily - daily cooking, high temperatures, frequent grilling - tend to see element failures at the lower end of that range. Brands like Bosch and Hotpoint typically use elements that are widely stocked as replacement parts, which keeps repair costs manageable. If your oven is under five years old and the element has already failed, it's worth asking the engineer whether there's an underlying cause such as a faulty thermostat cycling the element too aggressively.

Can I replace an oven heating element myself?

In theory, replacing an electric oven element is something some confident DIYers can manage - it involves disconnecting the power, removing a few screws, and swapping the component. In practice, the risks are worth considering: incorrect fitting can damage terminals, and some oven models have non-obvious access routes that make the job harder than it looks. Gas oven repairs are a different matter entirely - any work on gas components must be carried out by a Gas Safe registered engineer, no exceptions. For electric ovens, if you're not confident working around electrical components, calling a professional is usually the right call. A mistake can turn a 140 pound repair into a 400 pound one.

Why is my oven not heating up even though the fan is working?

This is one of the most common presentations of a failed lower heating element in a fan-assisted electric oven. The fan motor and the heating elements run on separate circuits, so it's entirely possible for the fan to operate normally while the element has completely failed. Other possible causes include a blown internal fuse, a faulty thermostat, or a failed temperature sensor. The Voltrade GoFIX diagnostic can identify the specific fault quickly, which is why our engineers typically know the cause within the first few minutes of a Littlehampton callout.

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

The answer depends on the age of the appliance and the cost of the fault. As a general guide, if the repair cost is under 50 per cent of what a comparable new oven would cost, repair is usually the better choice - financially and environmentally. An oven over 10 to 12 years old with a major fault such as a failed control board may be approaching the point where replacement makes more sense. For common faults like element or thermostat failure in ovens under eight years old, repair almost always wins. Ask your engineer for an honest assessment before committing either way - a good engineer will tell you when it's not worth fixing.
