F7 — Lock Motor Relay Watchdog Fault

F7 means the EOC tested the door lock relay for proper operation and the relay failed that test — a lock motor relay watchdog fault. It is not a stuck touchpad key (a shorted keypad is F1 on older boards or F11 on newer ones).

How to fix it

  1. Power-cycle the range (unplug or breaker off) for a few minutes and retry to rule out a one-off glitch.
  2. If F7 returns, the documented fix is to replace the electronic oven control (EOC) — the lock-relay watchdog circuit on the board failed its test.
  3. Don't replace the touchpad for this code — F7 is not a stuck-key fault.

Why it happens

  • EOC lock-relay watchdog circuit failed its self-test The documented cause — the microprocessor checked the lock relay's operation and it failed the test.
