Won't run i have a digital thermostat on the freezer that looks like it is working but the contaacts will not pull in


The first thing you need to check is if the contacts are getting power to the coil. A safety may be preventing the compressor from coming on. Read the wiring diagram. If the digital thermostat has a display, I would rule out the transformer. But I'm guessing at this point with what little info.

TRUE freezer model number GDM-49F.


Your unit should have a defrost timer.The timer may be stuck in a defrost.It should be located at the bottom of the unit next to the compressor.Open the door to the timer and observe the position of the timer.If you turn the knob and the unit starts up,it's the timer. If this is the case, you can purchase a new one at any local a/c supply.Let me know,Mike

Freezer Not Fan not running!


Most all commercial freezers have some sort of fan delay/ defrost termination device. Commonly called a "Klixon" (pronounced clicks-on). It is a device that is attached to the evap. It's function is to terminate the defrost cycle when the evap reaches a certain temp, say about 50 degrees or so, to ensure there is no build up of frost/ ice on the evap. It then allows the compressor to run, and cool the evap down to a reasonable temp., say about 20 degrees, and then let the evap fan come on. It prevents overloading the compressor during a high temp condition, and it also prevents circulating warm air left from the defrost cycle. I believe this device is most likely your problem. With no air circulating, the box will no cool down.. I have seen them burn and/or slhort internally. They can come apart. too. I would look here for that problem. the True manufacturing website does not give alot of info on this piece of equipment, such as a wiring diagram but manuals are available. Check this out and let me know how it comes out.

Timeclock Not going in defrost - True 49 cu. ft. / 1388 liter Commercial Freezer GDM-49F-RC


Http://www.truemfg.com/pdf/InstallManuals/GDM/gdm_english.pdf Go to this web site and check out the owners manual. On pages 13 or 14, it discusses the time clock. If the time clock is not moving to begin a defrost cycle, I would say, replace it. It does have a mechanical motor and it can fail or lock up. Hope this helps.

Coil freeze up - True 49 cu. ft. / 1388 liter Commercial Freezer GDM-49F-RC


If the fan works , probably the unit is low on refrigerant, which means there is a leak that has to be fixed and then recharge the unit .Also could be the defrost system (heaters ,terminator or deefrost timer ).
