The power went out in our house when it did the 31kenmore stove locked the oven door and we can't get it open can you tell us how to unlock it?
Mine did this in the middle of cooking thanksgiving dinner, the stove is in self cleaning mode and will not unlock until the cycle has finished. Our turkey caught fire ( the oven temp went into overdrive for the self cleaning ) and I pried the door open with a big screwdriver. Even though the bird was black it was awesome on the inside. You need to see if you can either cancel the self cleaning cycle, or let it run through. perhaps if you unplug it you can manually unlock the door. The lock mechanism should be electronic and should also have a manual lever.
Your 1998 F150 has 3 relays for your power door locks : an all unlock relay / a driver unlock relay / and an ALL LOCK RELAY I'm guessing that the ALL LOCK RELAY has failed I'm sorry but I haven't found the location of the power lock/unlock relays on your F150 yet ( does anyone know the location of the power door lock / unlock relays on a 1998 F150 ? )
