Our harvest assist is not working and we suspect this is the problem .Can you tell us where we can download some colored pics of the relay wiring for this model please
Phil, What is the full model number. like ICE0405 or EMF 405, or CF405. The 5 FA just means it 240 volt full cube, air cooled.But the style prefix is important. I believe you may have a ICE0405FA, so here is a service manual. The harvest assist is powered by 2 black wires. One is wire nutted to a white that goes to the main contactor hot side white. The other goes to the cam switch NO black terminal. That same black wire that shares that terminal goes to relay 1 NO that receives power from the harvest timer. Your wiring diagram is on page G7. Make sure to read Cam operation on pages F7 and 8
service manual for Ice-O-Matic
Guess I didn't quite answer that part. It goes to the timer initiate temp control that senses the tail coil temp.
