OVEN & HOB FAULTS

Fan Oven Not Heating

A fan oven may stop heating because the circular fan element has failed, the fan motor is not running, the thermostat is faulty or the control is not switching power.

!

Isolate electrical power and stop immediately if gas is smelled

Ovens and hobs combine mains electricity, high temperatures and, on gas appliances, combustible fuel. Do not dismantle while energised or continue using an appliance that trips, sparks, smells burnt or leaks gas.

MOST LIKELY CAUSES

Start with these

Fan element failed The circular element around the fan may be open-circuit.
Fan motor fault Air does not circulate through the cavity.
Thermostat or sensor fault The oven may not regulate or request heat.
Control or wiring fault The element may not receive power.
◫ Symptom variations Match the exact heating, ignition or control pattern. ⌄
  • Fan runs but no heat
  • Heat works on grill only
  • Fan is silent
  • Oven warms very slowly
  • Trips when fan mode is selected
✓ Quick checks Simple checks before removing panels. ⌄
  1. Note which function or zone fails.
  2. Check the appliance lock, timer and selected mode.
  3. Confirm the cooker isolator and breaker are on.
  4. Look for visible element, seal or burner damage.
  5. Isolate before touching internal parts.
If the issue is a setting or obstruction: operation should return immediately.
If there is tripping, gas smell or internal failure: stop and call the appropriate engineer.
1 Step 1 — Try another oven function Isolate the appliance before removing covers or touching internal parts. ⌄

Process

Check whether grill or conventional heat works.

Success looks like: The fault is isolated to fan mode.
Escalate when: Failure on all modes suggests supply or control issues.
2 Step 2 — Listen for the fan Isolate the appliance before removing covers or touching internal parts. ⌄

Process

Select fan mode briefly and confirm whether the motor runs.

Success looks like: The likely fault area is narrowed down.
Escalate when: A stalled or noisy fan needs service.
3 Step 3 — Inspect the fan element visually Isolate the appliance before removing covers or touching internal parts. ⌄

Process

With power isolated, check for cracks or blistering.

Success looks like: A failed element is identified.
Escalate when: Electrical testing is still required before replacement.
⌁ Common causes explained Why oven and hob faults develop. ⌄

A fan oven may stop heating because the circular fan element has failed, the fan motor is not running, the thermostat is faulty or the control is not switching power.

The affected function is the strongest clue. A single failed mode points toward one element, ring or switch, while a total loss of operation suggests supply, control or safety-device faults.

⌘ Advanced diagnostics Engineer checks and repair work. ⌄
  • Test fan element resistance and insulation.
  • Test fan motor.
  • Check thermostat or sensor.
  • Inspect wiring and connectors.
  • Verify selector or control-board output.
▣ Parts that may need replacing Common components linked to this fault. ⌄
  • Fan element
  • Fan motor
  • Thermostat
  • Temperature sensor
  • Control board
! When to call an appliance engineer Conditions that should end basic troubleshooting. ⌄
  • The oven or hob trips the electrics.
  • There is a gas smell or unstable flame.
  • Internal electrical testing is required.
  • The appliance must be dismantled.
  • Controls, elements or wiring show heat damage.
  • The fault returns after basic checks.
? Frequently asked questions Common oven and hob questions. ⌄

Can one failed element stop the whole oven?

It depends on the model. Often one cooking mode fails while others still work.

Why does an oven trip only when hot?

Element insulation can break down as it heats, causing leakage to earth.

What should I do if I smell gas?

Turn off the appliance, avoid sparks or switches, ventilate the area and contact the appropriate gas emergency service or registered engineer.
