Patrick for Model Number JKP45BW1BB I have gone through several part replacements on this older oven (original with house 15 years ago), replacing the control panel and ECB, then finally the upper door latching motor assembly. However, the motor appears to be stuck in an impossible state--the motor shows UNLOCKED when the rotor arm assembly (and door) are LOCKED, and it shows the reverse (door is unlocked and open when the switches are in the LOCKED position. As this particular motor is so poorly designed for access (the switches are impossible to get at without removing it from its mount, and then only with some difficulty) it's quite a chore but I'm willing to try anything that will reset the motor into a sane state. One post my wife ran across but doesn't have a link for is a suggestion that the motor power wires (red tabs) were crossed somehow and this caused the situation. I tried reversing them but still get the frustrating blinking "locked" signal on the panel and a complete shutdown of whatever action was tried (Self-clean or bake) in mid-process because the programmed logic apparently can't correct itself. Is there ANY way at all of resetting the motor into a sane state so that the rotor is where it's supposed to be when the switches say LOCKED/UNLOCKED???
Answer Hi Patrick. First turn off the power and wait a couple minutes, then reset the power on. Make sure the door switch part # WB24K5061 is operating ok because it interrupts the door latch power. Cycle the self clean to reset the new latch motor into the proper position. Use a volt meter part # MA-DM1 to see if you have 120 vac out put from the back of the clock at L-1 to MDL 1 & 2. This assures the clock relay output. If not then you need the control part # WB27T10290. Check all internal connector terminal pins to see if they are connecting when applied. Thank You. Read More...
