Kenmore Microwave Error Code F2 — Thermistor Short During Cooking
What this means
Error F2 indicates the thermistor is registering a short during cooking — specifically, no temperature rise was detected within 10 seconds after cooking started. This can mean the magnetron is not producing microwaves, the thermistor is shorted, or there is a control board issue.
Step-by-step fix
3 stepsPower cycle
Unplug the microwave for 5 minutes and try again.
Test with a cup of water
Place a microwave-safe cup of water inside and run for 30 seconds. If the water does not warm, the magnetron may have failed.
Schedule professional service
Magnetron and thermistor testing requires professional diagnosis due to high-voltage components.
When to call a professional
Do not attempt to access the magnetron or high-voltage components yourself. Professional service is required.
