SOURCE: 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

Try defrosting the unit by shutting it down until all ice is gone. If this corrects the problem and the ice returns you may either have a defrosting problem or a low freon charge.

SOURCE: I have TRUE freezer model number GDM-49F. the compressor start but the evaporator fan wont start what culd be the problem

Could be a number of things. It has a thermistor that sits on the evaporator to keep the fan off until it gets cold. It also has a switch above the door that switches the fan on when the door's closed. It could be a loose connection in the wiring, or, lastly, it could be a seized fan

True 49f goes into defrost mode the contact opens for the compressor but the compressor keeps running


in many cases, these units have relays or contactors where the contact points actually weld together. this causes the unit to stay running even though power to the coil has been stopped. I'd start looking there first. don't over look the possibility that someone could have mistakenly miswired the unit.

True upright freezer. coil fan not running.


Let it run. Coil temperature has to be low enough for the fan delay switch to close.

Temperature at 10 degrees


check condenser fans, if defective or running slow change it

if condenser fan is running, suspect a compressor with internal mechanichal problems, it will run but i can't guarantee how long, maybe a couple of weeks or days. if it's an copelamic compressor, it's going bad.

True freezer gdm 35f to cold


you just have to change the temperature control. I recommend using a white rodgers part no. 1609-105 set the cut out to about 33 cut in at 38 or 39 you might have to set defrost time to less minutes about 5 or 6 if coils dosent frezze with the setting i gave you. the bulb of the temperature control can be placed on the border dof the difusser.
