Common GE oven affliction: "Locked Door" light suddenly appeared. Door is not locked, no self-clean was started, lock feature is automatic lock, not a manual latch. I have: a) shut down power via circuit breaker; b) run clean cycle for 3 hours. All to no avail: Locked DOOR light has remained after each attempt. I even removed all of the wires from the lock motor, but after powering back up, "Locked" light flashing returns. So the oven is not usable. I am wondering if this is an issue with electronic control unit and not the more common explanation of a faulty lock motor. I will order a new ECU if so...........

Locate the 8 pin connector at the control board and unplug it. Check for continuity between the wires connected to the pins 4 & 5 and 3 & 5. The normal readings with the door unlocked suppose to be: between the pins 4 & 5 - infinity, between the pins 3 & 5 - close to 0 Ohms. If the readings are correct, replace the control board. If the readings are incorrect, replace the door latch assembly. - The control board Part number: WB27K10160

Gene: one add'l comment: would it not be the ECU, since I have already removed the lock motor wires and yet the "Locked Door" light remains? Thank you, chuck mchugh

Chuck,
It does not mean anything because the control board did not sense the latch at all after you removed the wires.
More likely the problem is a bad control board but I would like to confirm it.
Gene.

Hi Gene: I replaced the lock motor and this fixed the lock light problem. You were right as usual. Unfortunately and surprisingly when I tested the burners they did not work: one burner fired and came on modestly; the other 3 fired on the same burner. So: turning all 4 burner switches creates a spark in the same burner only! chuck

About the new problem I'm afraid I did not get it clear. Wherever you turn on any burner knob all burner igniters should spark. Can you explain more specifically what is going on please? Gene.

Hi Gene: I brought in a local repair man yesterday: in lifting the stove to access the Lock motor, I broke 2 of the small pipes that carry gas. My bad, although the repair is trivial. Anyway: thru your help I learned that ovens have lock motors that often fail, that removing wires from the lock motor will not remove the flashing LOCK LIGHT. Thank you for the education. chuck
