AEG Oven: not heating
What is this symptom?
If your AEG oven powers on but fails to heat, you're likely experiencing a common issue. The display lights and fan may operate, yet the oven does not generate sufficient heat in any mode. This problem can arise even when selecting the correct temperature and function, impacting both conventional and fan-assisted cooking modes.
Possible Causes
Faulty heating element
How to Identify: Oven stays cold when heating element should be active; visible cracks or blisters on the element; no continuity when tested with a multimeter.
Part: Heating element
Thermostat or temperature sensor failure
How to Identify: Oven fails to heat to set temperature or stops heating early; inconsistent or incorrect temperature readings; multimeter shows abnormal resistance.
Part: Thermostat/temperature sensor
Blown thermal fuse/safety cut-out
How to Identify: No heat and possibly repeated trips on thermal safety; continuity test on thermal fuse shows open circuit.
Part: Thermal fuse/safety thermostat
Control board/electrical supply fault
How to Identify: Display error codes, unresponsive controls, oven powers on but no heat; irregular electrical behavior.
Part: Control board/power relay
Incorrect oven settings or demo/lock modes
How to Identify: Clock not set, child lock or demo mode engaged, Duration/End function set incorrectly; indicated on display.
Part: User interface/settings
