defrosted freezer compartment manually due to icing
Ice on the ice maker or frost on the evaporator cover? How did you defrost it? Is the bail arm on the ice maker all the way down?

no ice on the ice maker worked properly before i had to remove it to remove the solid ice on the evaporator. put everything back together and ran the diagnostic to see whats causing the freezeup on the the evaporator. it shows the mullion heater and damper are a problem. running two days now . no frost and no ice on evaporator cover. what could i have done to the ice maker.

OK, take the cover off the ice maker power module and locate holes "L" and "N". Use your meter to check for 120 VAC.

If the voltage is correct, try to force cycle the ice maker. Use a small wire bent in the shape of a "U" and short holes "T" and "H". When the white gear starts to turn remove the wire then close the door. You may need to hold a door switch in to get it started. The ice maker will complete a harvest cycle and then fill for about 7 seconds.

OK unplug the ice maker and measure the voltage across the white wire and the black wire in the connector. If your meter indicates 0V, check the door switch for continuity. Just because the light turns on doesn't mean the switch is good. The door switch is actually two switches. You should have continuity between COM and NO when the button is pressed in.

Rick,
followed your instructions. door switch is good. power to ice maker is good. no power to the front of ice maker. i ordered the 8 in harness that runs along the back of the ice maker. there is no voltage through the black wire. is that a resistor or a thermal fuse? should get it on monday. hopeful that will solve the problem. i ran the dianostics mode test and the results a very confusing. here are the results.

well i did manage to get an ice maker. installed and it works. however after two days i am back to square one. frost on the back panel that is probably covering the evaporator again. when i run the diagnostic test it shows the damper door and mullion heater are bad. can you help me out. seems like i am starting all over again.

OK, I think you had two problems, a defrost problem and the ice maker problem. The ice maker issue is solved but you still have a defrost problem. On the main board, disconnect the P1 and P2 connectors and use your meter in the connector to check for continuity between P2-7 (brn) to P1-2 (wht). If your meter reads open, check the defrost heater for continuity.
