Miele Oven: not heating, excessive noise
What is this symptom?
If your Miele oven powers on but fails to heat properly and produces excessive noise like humming or vibrations, it can be frustrating. This issue may arise from a faulty heating element, a malfunctioning temperature sensor, or cooling fan problems. Understanding these causes can help you determine the next steps for resolution.
Possible Causes
Faulty heating element (bake or broil)
How to Identify: Oven does not get hot; visible damage (cracks, blistering on heating element; element does not glow when heating.

Malfunctioning temperature sensor or thermostat
How to Identify: Oven significantly underheats or overheats; temperature measured with an oven thermometer differs greatly from set point.
Part: Temperature sensor/Thermostat
Cooling fan issues or worn bearings causing noise
