Sounds like the bin switch. If it stays in the open position then the machine thinks it is full of ice and go to automatic shut down.

This light is a harvest limit light. This light's primary function is to be on as water contacts the ice thickness probe during the freeze cycle, and remain on throughout the entire harvest cycle. The light will flicker as water splashes on the probe. The lights secondary function is to continuously flash when the ice machine is shut off on a safety limit, and to indicate which safety limit shut off the ice machine. Start up of machine after turned off. !. Before the ice machine starts, The water pump and water dump solenoid are energized for 45 seconds to purge old water from the water trough. This ensures that the ice making cycle starts with fresh water. The water fill valve energizes after 45 second water purge, and remains on until the water level probe is satisfied. 2. to pre-chill the evaporator, there is no water for the first 30 seconds of the freeze cycle. 3. The water pump starts after 30 seconds pre-chill. An even flow of water is directed across the evaporator and into each cube cell.

Replace bin switch if switch is bad if switch is good then replace board.

Try cleaning the radiator for the ice box compressor it could be tripping it's thermal overload switch, if that doesn't work check to see if the termostat setting is in the range for the compressor to turn on when the ice starts melting.

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

Just click on the link to expand the search and go down until you get to the "Q" series and select the "troubleshooting guide" and any other parts of the tech manual you need, it's all there including the technician's guide too.

Hope you found this info very helpful and best regards!

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.

you will have to find the main board unplug the connector for about a mintue plug back in. This should reset unit

This is a Manitowoc model QY0214A. The water tough starts to slush up after about 3 minutes after start up cycle. The slush prevents water from flowing to the pump for circulation.
What can be wrong?
