Why Is My Oven Not Heating?
An electric oven that appears to switch on but does not get hot often has a failed fan oven element, grill element, thermostat, selector switch, thermal cut-out, or wiring fault. In fan ovens, the rear circular element is one of the most common causes when the lamp and fan still seem to work.

Before you order, use Confirmed Fit
For advice and repair topics like this one, the biggest buying mistake is ordering on appearance alone. Search by the exact model number wherever possible, because small appliance revisions can use different seals, filters, motors, pumps, lamps, shelves, or trims.

At a Glance
- This guide explains the most likely causes when an oven stays cold or only gets slightly warm.
- Fan ovens often fail due to the heating element, while overheating or control issues point more toward thermostat or switch faults.
- Estimated time: 20-90 minutes depending on access and the component being checked.
Safety First
Disconnect power fully before removing the oven from housing or touching internal components. Ovens can retain heat and have sharp metal edges, so work only when cool and wear suitable hand protection.
Common Causes
- Blown fan oven element
- Failed grill element or top heat element on some cavity designs
- Faulty thermostat not sending power to the element
- Selector switch or function switch fault
- Thermal cut-out or wiring failure
- Timer or control fault where fitted
Quick Checks First
- Check whether the oven lamp and fan come on when a cooking function is selected.
- Listen for the thermostat clicking as the temperature is adjusted.
- Look for obvious bulging, splitting, or burning on the oven element after removal.
- If the oven trips the electrics, stop using it until the element and wiring have been checked.
- Compare the selected function with the symptom: some faults affect fan cooking but not the grill, or vice versa.
Diagnosis and Fix by Cause
Fan oven element failed
- This is one of the most common faults on fan-assisted electric ovens.
- The fan may still run, the lamp may still light, but there is little or no heat.
- Remove the rear cavity cover, inspect the element, and replace it if damaged or electrically open circuit.
Thermostat fault
- If the oven does not regulate temperature properly or never energises the element, the thermostat may not be switching correctly.
- Thermostat faults are more common when the oven either stays cold or runs too hot with poor control.
Function selector or timer issue
- If one mode works but another does not, the selector switch is a strong suspect.
- If nothing heats and the timer display is blank or not set correctly, check the timer/control logic first.
Tools & Parts
- Screwdrivers, nut drivers, insulated pliers, multimeter
- Model-specific fan oven element, thermostat, or selector switch
FAQ
Why Is My Oven Not Heating?
An electric oven that appears to switch on but does not get hot often has a failed fan oven element, grill element, thermostat, selector switch, thermal cut-out, or wiring fault. In fan ovens, the rear circular element is one of the most common causes when the lamp and fan still seem to work.
How do I get a Confirmed Fit oven & cooker spare part for this fault?
Use the full model number exactly as shown on the rating plate. When Spares2Repair matches that model to a compatible part we call it Confirmed Fit. Similar-looking parts can differ across revisions, production runs, and variants, so model matching is the safest route before ordering.
When should I stop and get professional help?
Stop and seek qualified help if the work involves unsafe live electrics, sealed systems, gas-related risks, or damage that goes beyond straightforward model-matched part replacement.
