Question about Manitowoc QD0452A Ice Machine
The compressor was not coming on so I replaced the start device which was fried and the capacitor which was holding 0 microfarads. Before that everything else was working, although my boss did clean the machine in the meantime. When I tried to start it up after that the harvest light blinked twice and nothing comes on in ice mode. In clean mode the water pump comes on and it drains properly, but thats it. I'm not getting a low voltage signal to my contactor. Its about 95 degrees F.

SOURCE: The compressor on a Manitowic
the order of things I would check are...
~if oil lubed, the oil level
~ a motor load test
~ the pump cylinder and piston assembly
It could be any number of things that are causing this problem, and I don't have enough info from you to guess more accurately than that.
Your compressor is probably failing, drawing excessive current, then shutting down on the overload device inside the controller. An amprobe would confirm this. Also, if the compressor takes a rather long time to re-start, that would confirm it.

sounds like you got a bad water level sensor.
