I am working on a Manitowoc QY1304A Ice Machine. It is 220v and the problem is the compressor will not start. I have checked the contactor and I have 220v on both sides. I did a resistance test on the PTCR and it is withhin tolerances. I checked at the compressor and I have 220v. The only thing I can think to do is replace the capacitor but I see no physical damage to it. It is not swollen or leaking. I tried testing it with a multi meter and the oms go up till they reach the top scale of the meter. If I short it it will charge again. I also checked the compressor for ground and found none. Check the compressor between the windings and they seem to add up fine. Please help, Joe
Manitowoc qy284a ice machine making ice but takes much longer to produce than in weeks past. getting about half the capacity from weeks past?
Does the compressor make any noise at all?
You can ohm out the compressor windings. I dont know off the top of my head which compressor manufacturer they are using but if it is Copeland you can get an electrical handbook and it will have ohm values for the compressor. If not assume the rule of thumb Common to Run is X, Common to Start is Y, Start to Run is X+Y, and Y should be 3 to 5 times whatever X is. On Rx10,000 scale check each terminal to ground should be open.

I'd think that the start capacitor is faulty and could be the problem.
Here's a parts list for the model you're working on that also contains several line drawings

Does the water run in machine or anything else, or is the machine totally idol? Look at controll board in electrical box, you should see at least 1 green led light let, do you?
water stop running in about a minute and yes green light is on and also a red ligth that flash very slowly
