Maytag Skybox not dispensing
« on: January 21, 2012, 03:26:11 PM »
I have a Maytag Skybox model MBV1976AAB.  The machine no longer dispenses anything.  Fluorescent lights in the door work, but no LEDs light up on any of the push buttons.  I replaced circuit board in the door, but that didn't help.  I checked all the connections to the MAIN PCB board in the back and all are connected.  The LED's on the MAIN PCB however are not lit.  Are there any other things I can check?  The unit still stays cold, just doesn't dispense any more.

I tried that before, but didn't work this time.  Usually when that is the problem, the LED lights on the push buttons will flash, but nothing happens.  In my case, the LED lights don't come on at all at any time on any of the buttons.  This time it's like there's no power to the door to trigger the dispenser motor to turn.

Check the transformer, 11001154.  Should have about 120vac to the primary and 12vac at the secondary.  If the transformer is good, that leaves the main control, 11001115, as the culprit.  Before ordering, I'd get out the magnifying glass and check for cracked solders.
