This was a service call on a manitowoc ice machine that had a bad fan cycle control.
Manitowoc ice machine condenser fan not working.
Standard remote condenser ice machines all use compressor hot gas systems to heat the evaporator during their ice harvest cycles.
In this video i show you how to troubleshoot the condenser fan on a manitowoc ice machine.
Air space clearances at back and sides of ice machine.
I have a manitowoc sd0452a that has a bad pressure switch not allowing fan to come on.
This also means the noise from the compressor is always concentrated at the ice making part of the.
If the ice machine continues to run the condition has corrected itself and you re good to go.
Ice machine not on separate fused electrical circuit.
If the machine does not work check the fuse and the circuit breaker.
To make hot gas systems work the compressor must be as physically close to the ice making evaporator as possible.
Assuming your ice machine is clean there are 2 other areas that are most common for shutting a manitowoc ice machine down on a safety limit 2.
I have a ice maker model qy0214a the ice machine will start up go through the pre chill mode and start pumping water but no ice forms and the unit shuts down after about 1 2 minutes and wont restart for 3 minutes.
My question is can i leave it jumped to get them by until i can replace.
Because there is not enough ice to force the water curtain open and break the bin switch the machine simply thinks it never harvested.
If the compressor will not start even if the gear motor is running check for water in the water reservoir.
Switch the machine off and back on again.
The compressor runs fine with proper current draw and the high pressure switch also does not trip.
It made ice several times after jumping the switch.
I explain why the fan speed fluctuates very erratically and how t.
Ice maker fills and compressor starts then kicks out on high pressure no fan.
When clogged the screen will reduce the flow of water.
The water must touch the probe in order for the compressor to start.
Make sure the water valve is open and that the float valve screen isn t clogged.
Ice machine not level side to side back to front.
Safety limit is triggered the safety limit on some manitowoc units is designed to stop the ice machine if there is a possibility of major component failure.
I checked across switch and it s not closing so i jumped but fan runs constant when cantactor pulls in.
If the compressor of the machine fails to start even with the motor running check for water in the water reservoir and see whether the valve is open or the float valve screen is clogged.
