What Does Error E15 Mean?

The AEG microwave error code E15 indicates an overheating condition within the oven cavity. This error typically appears during or after use and is accompanied by the microwave stopping operation until it cools down. To resolve this issue, it's essential to allow the appliance to cool for 10-20 minutes. If the error persists after cooling or if there are signs of burning smells or unusual noises, further inspection of the ventilation and thermal components may be necessary.

Common Symptoms:

  • Error E15 appears on display during or after use
  • Microwave stops operation until it cools down
  • Code clears after cooling and restarting

Possible Causes

  • Internal temperature of the microwave cavity is above safe operating limit (high)

How to Fix Error E15

DIY Fix Allow the microwave to cool down

Technician Only Inspect ventilation and thermostat/thermal cut‑out components

  1. Disconnect power and allow the unit to cool.
  2. Verify that all vents and airflow paths are clear of obstructions or debris.
  3. Test the temperature sensors and thermal cut‑out switches for correct operation using appropriate diagnostic tools.
  4. Replace defective sensors or thermostats if they do not meet manufacturer specifications.
