I have True GDM-41 unit was cold yesterday not today. Compressor will not kick on today. Can it be anything other than compressor?

By not hearing anything but the fans I would have to say the compressor is not running. Pull the cover off so you can access the condenser area where the coil and compressor are located. Check the coil and ad make sure it is clean. Then feel the compressor and find out if the compressor is hot. If it is hot and the coil is dirty/dusty I would say it was going off on high head pressure/temperature. Clean the coil and let the unit sit off for a while and then try running it. If it is cool then it may have an issue with the refrigerant or other things like maybe start componenets.

Try turning down the temperature or get the thermostat checked.

Hello Margarito539,

I understand that you purchased a True GDM-41 merchandise refrigerator and you are having a problem with the temperature. The thermostat you are currently using is an in-line thermostat and is not the proper thermostat for the unit I would suggest that you follow the below link and purchase the proper thermostat for the unit. http://restaurant-equipment-parts.com/part/true/800393 the cost is $36.98 and is an OEM part.

You also may need a service tech to check out the freon in the unit. The unit uses 134A freon and must be within a few ounces of charge other wise it will not work properly. As the unit is keeping it 60 degrees, before you do anything make sure that you can hear the compressor running as this is not a cheap fix, however may be worth the cost for the unit you have. The compressor should be humming if it is not and the unit has been plugged in for a while, unplug for about thirty minutes and let the compressor cool. Once thirty minutes has passed plug in and see if the compressor is humming.

After checking the compressor you have two choices if it is humming call a service tech and have them check the freon charge and thermostat or change the thermostat and see if the compressor starts cooling the unit. If the compressor is working then the box is well worth fixing, if the compressor is not working you need to decide if it is worth fixing. A used unit with a one year parts and labor warranty costs $2100 so the repair should not cost over $1000 to be economical.

you should check the condensor first make sure it is not dirty. Inside and outside fan works.

Either the compressor is going bad or the start relay on the compressor is going bad. The relay is under the plastic cap on the compressor it will be a nickle size round disc with one wire hooked to one of the 3 prongs coming out of the compressor. This is what you hear click. But to be honest normally this points to a bad compressor and then its time for a new fridge. Hate to give bad news good luck

GDM-41 would be the unit model number???
If you want to get a compressor model number that would be on the compressor tag on the compressor itself. I would not bother with a True part number just get the Copeland or Tecumseh number off of the compressor and get a replacement from a local wholesaler. On this old box do not rule out brittle or shorted wires. I haven't had success with converting a box like this to R-134a unless I change the entire condensing unit and would tend to go with an interim replacement like Hot Shot or R-409A or something like that. The box probably won't last long enough to make R-134a conversion viable.

good day,
hope this link below will solve your problem.

Good day,
First step is to check to see if there is power getting to the compressor. If not you'll need to back up and find where the power was lost. Some models have a low pressure cut out pressure switch. One possibility.
Second, if power is at the compressor then you'll need to check the protective overload, start relay, and start/run capacitor if it uses one.
If everything checks out, using an ohm meter check the motor windings. They may be open ( no continuity) bad compressor.

Probably the cold control (or thermostat ) is bad .Unplugged the unit and bypass the cold control by putting together the two wires and wrapping them with electrical tape . If the compressor runs , replace the cold control ,if not the problem could be with the start relay.

turn thermostat all the way to the left to turn it off. restore power and see if it stays on and inside fan is running. Then turn thermostat to rite to turn on compressor. If the power trips when turning thermostat back on, the compressor may be bad. :(
