True 52 cu. ft. / 1472 liter Commercial Freezer TM-52F Questions & Answers
Amount of refrigerant that carries this freezer is
Those freezers utilize R-404A refrigerant. The amount of refrigerant will be displayed on the data plate on the inside of the unit usually on the left inside panel. It will have the type and weight of refrigerant...
However, yes, 1.6 lbs sounds about right for those models.
I have a True Freezer, the compressor comes on but

Go to this web site and look in the manual on page 15. Check "Compressor runs but will not refrigerate". Gives some suggestions.
Now, inside the evap, usually strapped or clipped to the coil "U" turn on the end of the coil, is a Klixon device. This device comes in many different configurations. There may be 1 or 2 of these. One is a defrost termination switch. When evap gets hot enough so no frost is present, it terminates the defrost cycle. The other is a fan delay. It comes on when the coil temp gets to about 20 degrees. This prevents circulating warm air from defrost cycle. Now if there is only one device, it can be 2 in 1. That is, a defrost terminator/ fan delay. Will most likely have 3 wires going to it where as the 2 separate ones will only have 2 wires to each one. Now, either this fan delay is not working correctly or the coil is not getting cold enough. When it gets cold enough, it turns on the evap fans. This is most likely where your problem lays. Check it out.
True commercial freezer
The ice could be preventing the freezer from freezing properly, try defrosting the unit. if this does not help then this could indicate a more serious problem like a bad temp sensor or refrigerant leak.
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.
