Oven isn't heating up

The oven powers on and the light works, but it never gets hot. On a fan oven the element behind the back panel is the usual answer, and it is one of the more economic appliance repairs there is.

Before you start

  • Electrical safety: Ovens are usually on a dedicated high-current circuit and must be isolated at the cooker switch, not just switched off. Element terminals can remain live if the isolator is not used.

  • Gas safety: If this is a gas oven, or you can smell gas at any point, stop. Only a Gas Safe registered engineer may work on it. Leave the property and call the National Gas Emergency Service on 0800 111 999 if you smell gas.

What causes it, most likely first

  1. Failed fan oven element

    Most likely

    The circular element behind the rear panel goes open circuit, often with a visible blister or break. The most common oven fault by a wide margin, and a relatively quick fix.

    How to check: With the oven isolated, look through the fan grille at the back for a visible break or blistering on the element.

  2. Failed oven thermostat

    Common

    The thermostat fails or drifts so far out of calibration that it never calls for heat. Sometimes preceded by months of food burning or never browning.

  3. Tripped thermal cut-out

    Common

    A safety cut-out has tripped after an overheat, often because the cooling fan failed. It needs resetting or replacing, but the cause of the overheat has to be found too.

  4. Timer or clock not set to manual

    Common

    Many ovens will not heat if the timer is set to auto. Genuinely common after a power cut has reset the clock, and it costs nothing to rule out.

    How to check: Look for an "A" or a clock symbol on the display and set the timer back to manual per the manual.

  5. Failed cooling fan causing repeat cut-outs

    Occasional

    If the cooling fan has failed the oven overheats and trips its cut-out repeatedly. Replacing only the cut-out means it will trip again.

What to check, in order

  1. Check the timer is on manual

    Look for an "A", "AUTO" or a clock symbol on the display. Reset the clock and set the timer to manual. After a power cut this alone fixes it surprisingly often.

  2. Check the circuit and the isolator

    Ovens run on their own circuit. Check the cooker switch on the wall is on and look for a tripped breaker in the consumer unit.

  3. Look at the element

    Isolate the oven at the cooker switch. Look through the fan grille at the rear element for a visible break, blister or burn mark. Damage you can see confirms the diagnosis.

  4. Book an engineer with what you found

    Telling them "fan oven, no heat, element looks blistered" means they arrive with the right part. An element replacement is one of the more economic appliance repairs and well worth doing on a decent oven.

Parts you might need

Typical UK prices for the part alone, before fitting. Worth knowing before you accept a quote — the part is often a small share of what a repair is priced at.

  • Oven element

    The heating element — usually the circular fan element behind the back panel on a fan oven.

    £15–£50

  • Oven thermostat

    Controls and limits oven temperature. A drifting thermostat shows up as food burning or never browning long before it fails outright.

    £20–£55

  • Oven fan motor

    Circulates hot air around a fan oven. A noisy fan is usually a dry bearing and a warning of imminent failure.

    £25–£65

Worth repairing, or replace it?

At the top of this range the repair costs a significant share of a graded replacement, which typically starts around £180. Worth getting the quote first, then deciding — on a machine under about five years old a repair usually still wins.

Is there an error code on the display?

If your oven is showing a code, that will narrow the diagnosis a lot further than symptoms alone.
