Followed many of the tips already posted. Optics consistently showed code that indicated they were bad. BUT yesterday (after I ordered new optics) odd codes seemed to come up, like a long and a short blink repeating. AND today just a few hours before my parts arrived the lights blink normally! (could a connection at the icemaker being loose cause this? I removed the icemaker again because I forgot to put the cover back on. That may have moved the connector enough to make a difference?)
Now I’m seeing (only) 95 volts across N-L, and the unit doesn’t move at all with a jumper between T-H.
Also, power doesn’t seem to ever get to the water valve. Putting external power to the valve for a few seconds added water to the icemaker, so the valve is OK and the line isn’t frozen.
I haven’t opened my new optics yet; it now sounds like the icemaker itself. Do you agree?
Thanks! (By lights blinking normally, I meant: flapper open - 2 flashes 1 sec delay repeats; light solid when flapper closed)
Before I installed new optics that was screwed up again! Now with new boards its OK
It seems I still need to check out ice maker - no water flows so power isn’t getting to the solenoid valve (yesterday I put external power to valve and water flowed to ice maker
I rechecked the L-N voltage with the new boards but couldn’t get a reading - maybe my connector wasn’t fully engaged. Still got only about 98 volts at the connector between black-white and white connections.
Applying external 120 v across black and white pins on ice maker and it did not move with or without jumper across T-H
Have continuity (0 ohms) from black pin to L, and from white to N
I did notice heater warming the mold.
Ejector blades are parked in the ice tray at about a 5 o’clock position (looking at the ice maker from the end with the water fill neck)
Motor has seemed to operate while I’ve been troubleshooting - But I can’t say for sure it was consistently. In fact I suspect it’s been on and off which has puzzled me.
