True 12 cu. ft. / 340 liter Commercial Freezer T-12F Questions & Answers
True Fridge Running Hard
I would try this: unplug unit and use a vacuum cleaner and vacuum out the entire area. Not sure what you mean by "running really hard"? If you mean noisy, then see if you can see source after cleaning. Try this and let me know if I can be of any further help.

Looking at pins on compressor, read like a clock. Common clockwise to Start clockwise to Run
Compressor very hot and running at twice the
Chances are that you don't have proper ventilation for this unit. Commercial appliances put off way more heat than home appliances and need to have space to 'breath'. If this freezer is surrounded by other hot appliances or if it is in a room with poor ventilation, you might want to considering moving it. If that doesn't solve the problem then contact a True Refrigeration rep to come out and look at. Most True models have a 5-year warranty on the compressor.

True Freezer Running Too Cold
thermostat is stuck closed, if not compressor relay is stuck closed, if not then the defrost timer is stuck closed. test the components in that order.
TRUE under counter FREEZER TU2-27F
Are both evaporator fan and condensor fan running?You stated that you topped off the charge.Assuming the charge is ok, the next thing to check would be the expansion valve.May not be metering the freon properly.A faulty expansion valve can trick you into thinking the unit is undercharged.It may be partially open and starving the evaporator.(Not freezing the water totally)You should have a even coating of frost on the evaporator coil when running.Hope this helps,let me know if i can assist you any further.
Takes weeks to freeze
If you freezer has a defrost timer it should have done the defrost on its own. Only the very old freezers had to be defrosted manually. If it continues to stop cooling or you already haven't had the timer replaced or the defrost elements checked let me know.
No door heat
The Mulluen heaters will be Built into the frame not in the door.
On freezer True T-23, the compressor works around 5 minutes and turn off for around 5-6 minutes and start again for another 5 minutes. I need help
That is what it is supposed to do. It is called cycling and switches off when the set temperature is reached. It is a commercial freezer, so if the door opened and closed often, that is normal?Commercial freezers and fridges have an item called a 'Clixon' that cuts power in the case of the compressor overheating. When was the last time the fins on the compressor coils were cleaned? Could also be a bad door seal letting cold air escape. When you close a freezer door on a unit like that, it should be really hard to open straight afterward due to the suction. Could be a faulty thermostat. Turn the temperature to the warmest setting and see if it still does it? If it does, you need a new thermostat.I just retired after 52 years in catering.https://www.katom.com/598-T23F.html?gclid=CjwKCAiArbv_BRA8EiwAYGs23PKtEzF60_OMVNpHXBlGjHQNdpp0pDZsu0G0lFLqVy2p4qIybG9n8xoCwEMQAvD_BwE..
Why is jenn air jcd2389ge hot around front freezer door frame?
The heat at the opening of refrigerator is usually a sign the condenser coils are dirty. Check the condenser coils for a restriction underneath the unit. Dirty condenser coils will cause poor air flow over the coils and compressor. Poor air flow will cause a lot of problems, including overheating the compressor, the refrigerant and the copper lines. This will destroy your sealed system. The coils need cleaning at least once a year, more often if you have pets.
I couldn’t determine if your unit has an “energy saver” setting. If so, turn it on. Not all refrigerators have energy saver. This is on units with emilion heaters in the wall around the door gaskets. The heaters are to eliminate condensation around the door. Turning ON energy saver turns OFF those heaters. You should notice a change quickly if it’s the heater causing the heat, that is, if you have that model.
Cleaning the coils will need a day or two to allow things to cool down before you notice a change in the heat around the door.
True 49f fans stopped running.
Compressor still runs. Fixes? Troubleshooting steps?
I am assuming you are relating to the evaporator fan(s) not running. If this is the case, some units have a 'Klixon" type thermostat in the evaporator so when the evaporator coil temp reaches a predetermined temperature, the fans come on. You may have a bad "Fan Delay" (Klixon) or the coil is not reaching the proper temp to activate it to turn on the fans. I would check the wiring diagram on the unit for this part to see if this unit has it in the system.
