These relays are calibrated in a specific direction to open the contacts. When you hang it upside down or sideways you are changing the calibration. This may not allow the relay to function as required and keep the start capacitor and start winding in the motor engaged longer than necessary. Long term this could cause no starts and failed relays and start capacitors and in the worse case a failed motor.

Possibly to avoid the possibility of water pooling on top of it and thus allowing the water to seep inside of the relay and kill it.

What is causing Scotsman icemaker to moan

perhaps it's unhappy? I can't say i blame it, if I had to sit there all day in the freezing cold making ice I would moan too.
here's a list of possible problems
If it makes excessive noise:-
Problem and Likely Causes/ Probable Solutions

Fan blade vibrates Blade is bent Replace fan blade

Fan motor mount is broken Replace motor mount

Compressor vibrates Mounting loose Check mounting

Water pump vibrates Pump bearings worn Replace pump

Panels vibrate Mounting screws loose Tighten screws

and ice can groan as it expands, but that only applies to large icebergs

Freezer wiring diagram

A "potential" relay is a voltage controlled start component for the compressor. If your sure the potential relay is bad, not the start capacitor or a seized compressor, Order one from G.E. and replace it.

How To Replace Relay On True T-72 Reachin

If it's mounted inside a box along with the capacitors there is 1 screw holding it from the back. Often you have to unmount the box from the compressor to access the screw.

Have a True Freezer. It will kick on but when shutting down it shakes like crazy

This can be due to poor mounting of teh compressor. If the freezer is old then the mounting bushes can be worn out and must be replaced. Also check on the mounting bolts as if these are loosely fitted the compressor will ******** moe specially when the motor stops due to the force.

Maytag Freezer quit working, Light is on, but not cold. Is there anything I can check before calling a service center. The model is MQU2057AEW.

According to your wiring diagram this is about the simplest machine in the world to work on. a369c99.gifMounted on your compressor is a relay. The relay allows all the copper windings in the compressor to be energized momentarily to get the motor in the compressor started, then it drops half the cooper out because that's all that is needed once it is up and running. A thermostat allows current in the circuit till the desired temp is reached. I would check that relay first for signs of wear. They go bad with age. 46684ba.jpg743f4b2.jpgIf the relay is good bypass the thermostat's to see if she comes to life. If she starts working replace the thermostat.

If you need further help, reach me via phone at

Circulation fans quit running after we shut down the compressor, and won't come back on . even though the fan when pluged direct to out let works.

check the door switches and see if they are engaging when the doors are shut. they are mounted just above each door. If just one is not being pressed in it will keep all of the inside fans off. also there is afan delay mounted by the inside coil that will keep the fans off until the coill cools to a certain set point to prevent recirculating hot air. depending on conditions it may take the fans a good 15 minutes to come on ,or longer in a very hot start up.

Buzzing compressor

heres a part number for the overload relay assy 5304468029.. its mounted on the side of compressor. its a tricky one, usually my experience has been the noise comes from a bad compressor( which you should have 5 year full warr from manufacture). sometimes the overload relay does go bad preventing compressor from starting,the n ew compressor will come with a new overload relay
