Electrolux EI30EF45QS 30 in 5.1 cu ft Built-In Electric Wall Oven with True European Convection F91 Error Fix: Door Lock Mechanism Failure — Cannot Unlock

Error code F91 on the Electrolux EI30EF45QS 30 in 5.1 cu ft Built-In Electric Wall Oven with True European Convection means: Door Lock Mechanism Failure — Cannot Unlock. The oven door lock mechanism failed to reach the fully unlocked position. This typically occurs after a self-clean cycle when the oven has cooled down and attempts to unlock the door. The lock motor runs but the unlock switch does not indicate the unlocked position. The oven cavity temperature must be below 550°F before unlock is attempted. If the temperature is low enough and the door will not unlock, check the lock motor and mechanism for binding. Power cycling the oven sometimes resolves the issue. If the door remains locked, the lock assembly may need to be manually released (consult the tech sheet) and then replaced.
