How to fix the F27 code

Unplug the oven or switch it off at the breaker before removing any panel or filter.

1. 1

   Step 1: Let the oven cool fully

   Wait at least 1 to 2 hours. The door may stay locked until the oven has cooled. Do not force it.

2. 2

   Step 2: Reset power at the breaker

   Switch off the breaker for the range for about 30 seconds, then switch it back on.

   Step 3: Listen for the fan

   Run Bake at 350°F for 10 minutes. You should hear the cooling fan running. If it is silent or grinding, the fan needs service.
