Oven not heating? Find out which function has failed
An oven may light up but never get hot, heat on grill but not bake, cook unevenly or trip the power as it warms. These symptoms point to different systems. Identifying the exact mode and behaviour is more useful than replacing the thermostat or heating element without testing.
Display on, but neither bake nor grill heats
This can involve a supply connection, function selector, safety thermostat, control board or another component common to the heating circuits. A live voltage check is not suitable for an unqualified homeowner.
Grill works, bake does not
Where the oven has separate heating elements, a single failed bake element or its switching circuit may affect one function while others still work. The exact design matters; a technician should confirm continuity and control operation safely.
Fan runs but cooking is slow or uneven
A fan-assisted oven may have a ring element, temperature sensor, fan circulation problem or thermostat calibration issue. Record whether it reaches the set temperature and whether the issue affects every cooking level.
Oven trips the breaker when heating
Stop use. An earth-leakage event or repeated breaker trip can indicate a deteriorated element, damaged cable or moisture-related electrical defect. Do not fit a larger breaker or keep resetting the circuit.
Electric oven versus gas oven
Electric ovens require electrical assessment; gas ovens may involve ignition, flame supervision or burner faults. If you smell gas, leave the area and arrange emergency gas assistance. Repairs on gas systems need the correctly registered practitioner.
Safe checks before a visit
Confirm that the clock or timer is not set to a mode that disables cooking, the door closes normally and the programme is selected correctly. Consult the user manual; do not remove live back panels or heating elements.
Built-in appliance access
Tell the booking team if the oven is integrated, has a flush trim or shares a cabinet with a hob. Removal may require coordination to protect cabinetry and disconnect the supply safely.
Repair or replace?
A confirmed replaceable element or sensor can make repair worthwhile, while severe corrosion, damaged wiring or unavailable control boards may alter the decision. Compare the assessed work with the condition and age of the appliance.

Frequently asked questions
Why does my oven light work but there is no heat?
The lamp has a different circuit from the heating system. An element, selector, sensor or supply fault may be involved.
Can I replace an oven element myself?
Electrical parts should be assessed and replaced by appropriately qualified personnel.
What if only the grill works?
That narrows the fault to some functions but does not prove one specific component has failed.
Is a tripping oven dangerous?
Repeated trips are a warning sign. Stop using it and arrange a qualified electrical assessment.
What if the oven temperature is inaccurate?
A sensor, thermostat or airflow problem may be involved; testing should verify the actual temperature.
Can gas ovens be repaired by any appliance technician?
Gas-related work requires practitioners qualified and registered for the applicable scope.
Do you need the oven model number?
Yes. The model or rating-label image helps with fault procedures and part identification.
Can repairs be arranged for a built-in oven?
Share cabinetry and access details so the suitable work scope can be confirmed.
