Measure the resistance across the outermost wires of the pump connector. Should be between 17Ω and 23Ω. 120 VAC is supplied from the control board, blue wire and white wire. I'll see if I can find the tech sheet for that model. Here's a strip circuit for ice making mode:
Hopefully last update on this one. Thanks for all the help.
I measured the resistance across the recirculation pump I removed and it was open.
The replacement one had resistance.
I installed the replacement recirculation pump, started the test cycle and when I got to the recirculation pump stage, saw water flowing across the freeze plate.
I have reassembled the ice maker with the new
pump and it is making ice once again.
