Is the compressor fan motor running?
If so, replace the capacitor on the compressor.

If no.
Replace the thermostat.

T-49 warm in the morniing, but then works fine all day


Sounds like you are letting the refrigerator sit in an unheated space at night. Those refrigerators have minimum temperature ratings as well as maximum temps. True Mfg. Can be more specific but I say not under 60deg F. Good luck hope this helps.

True T-49 refrigerator/freezer temperature calibration


Contact the manufacture, it is most likely going to be covered under warranty. If the knob is not removable, (check for a set screw on the side of the knob it will take a small allen wrench) Then the thermostat (temp controller) will need to be replaced, if it isn't a style that you can calibrate.

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.

I have a True Freezer Model T-49. It works fine but every 3 or 4


This sounds like a stuck relay to me. I have seen this problem before. The defrost clock kills power to the compressor relay coil during defrost. If the contacts in the relay are welded together the compressor runs while unit is trying to defrost. On newer units this relay is mounted in base of unit on the side or back of the electrical box near center bottom of unit. The compressor relay is a small rectangular box with 4 wires attached. It can be replaced with a single pole 20 amp contactor with a 120 volt coil/ or 240 volt. Check the units name plate voltage rating and ratings on old relay! ;)

I have a 2 door reach in true freezer which is now just keeping a steady 5 degrees about temp, should be 0 -10, fans, compressor, fans evap are all runing okay, the coils were clean, so what could the...


If its getting warmer or more humid where you are this is probably a sign of needing to clean your outer coils. Remove the panel covering the compressor and check the condition of the coils. Clean with a nylon brush or wire brush. Or blow out with compressed air.

If the outer coils look OK see if they feel warm up and down the sides. If they don't you may have a defrost problem. If they are warm recheck them in 30 minutes if still warm or warmer and no one has opened the door check the lite inside, and the fan inside (it will only run with door closed). Hit the switch and see if lite goes out and make sure the switch is being activated with the door closed. And check the door seals any vinyl cracked on them they need replacing but can be warped sometimes letting in warm air (usually a sign of frost inside the door or water leaking out but not always).
It could be low on refrigerant or an inefficient compressor but not likely as much as these other items are.

The last thing is the thermometer could be reading wrong or out of calibration. Is it Electronic? Yes - Then its most likely one of the other problem before. If its mechanical (bi-metal) get another thermometer you trust or a new one and check it before you trust it. 2 of them telling you its 5'f then Id believe it other wise one or both of them are wrong.

True t-49 refrigerator


Yes it can. You would have to call a service company to recover the refrigerant, remove the oil in the compressor. They would then replace the oil as well as the refrigerant. The metering device would also need to be changed, along with the thermostat.

T-49 delivery - set-up


Make sure that the service valves are open. After you have checked that, hook up your refrigeration gauges and verify that you have not lost all of your refrigerant. Please do this and let me know if you need any further guidance.
