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

Most commercial refrigeration supply houses should be able to help you with getting the heater or if not at least give you a steer
as to where to go or who to contact. Some are really helpful, others can be real jerks. Sorry but without knowing the area you are in I cannot give you more info than that. Did you Google the Brand name of the freezer ?????

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.

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.

Timeclock Not going in defrost

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.

My 3 glass doors cooler

There are generally 2 reasons why this would happen. The defrost timer or heater has gone bad. Or, the fan is not working. Because you state that it runs all day long, I would think that the coils are now a block of ice and cannot cool. In any case, manually defrost it now. Turn off the power and use a hair drier on low (not hot) setting. This should fix the electrical cost for now. Then you can determine if the fan is running properly, or the defroster.
