This video from Sears PartsDirect shows what to check when your range flashes an F90 error code. This code can appear when you try to lock or unlock the oven door, or when you try to run a self-cleaning cycle. The F90 code means the electronic oven control board detects a problem with the door lock system. Watch this troubleshooting video to learn how to examine the components in the door lock system—including the control board, wiring and oven door lock motor assembly—and find out which part has failed.
The video covers Kenmore and Frigidaire ranges with the oven door locked and F90 appearing in the display. The F90 code also appears on these types of ranges when the control attempts to lock the oven door but the door won't lock.
