    We had this problem -- technician came out and reset the defrost clock...he said it was a common problem with True units where the clock pulls out of defrost cycle too soon which freezes up the system.

    My True commercial freezer is running constantly without cutting out. When I unplug it and thaw it for a few hours it seems to work again for a short period then the same thing happens again!

    Freezer is only reaching temp of 30 degrees. Tech. has replaced thaw swith that was stuck, checked fans and is now detecting a freeon leak in the back panel. there is not evidence a leak any where else.

    The compressor fan works, but the compressor does not. The compressor gets warm after about 15 minutes.

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.

Coils ice up

My best guess is that the drain has some debris in it and the defrosted water from the coil is being picked up and being re-frozen against the coil and freezing up the drain pan. The defrost timer may have failed, the defrost termination button fastened to the coil may have failed, the defrost heater on the coil itself may have separated from the coil or just outright failed. Hope this helps and good luck.

We have a True TS-49F freezer that the interior fan have stopped working. Holding the door switch does not activate them. Unit is out of warranty.

Most all commercial freezers like yours have, what is called, a fan delay. It is located in the evaporator case and is usually attached on or very close to the actual cooling coil. It may also be a combination switch known as a defrost terminator/ fan delay. It's purpose is to keep from circulating warm air. If the cooling coil does not reach a preset temp, the fans do not come one. Another thing is that the fan motor may just be bad. If you have more than one fan, then chances are that it's going to be the fan delay. I would start there to see that either the fan delay switch is bad or there is a reason that the coil is not getting cold enough to activate the switch.

My true freezer temperature gage has a P1 flashing code

If unit keeps proper temp. then I would think that either the thermometer sensing probe may have been damaged during the repair process or the thermometer itself has failed.

Can anyone tell me what My Kenmore upright freezer 20cu ft should be at? temperature I mean?

Freezer temps can very, but as we know freezer temps can run from +32F to -40 or more on commercial boxes with the different freons. But back to you, I would say from my charts on low, med., temp refrigerators, you should be around +8F to -5F. When I mentioned +32, we know that's when water starts to freeze, so you want the freezer to be much colder then that.In order to keep ice-cream frozen, you must cycle around -5f to -10f.I sincerely hopes this has helped you out, as you will I am sure get many different opinions, but +8 to-5 is excellent for this box.
Sincerely,

The freezer will not freeze or keep its

Check to condenser coil and make sure it is clean and the fan near it is running when the compressor is on. Check for ice build up in the freezer. If the evaporator coil is iced up the box will run warm. It may be a defrost problem, a dirty condenser, or a refrigerant issue.

We have a true T49F freezer and the evaporator fans are not running. The compressor is running on startup. The coils are cold. But are freezing up. Shouldn't the fan be on, or does the cabinet have to...

Freezers have a sensor that is referred to as a "Fan Delay/Defrost Terminator". It senses the temp during the defrost cycle. Usually, when the evap temp reaches about 50 degrees, there should not be any frost or ice on it. This device terminates the defrost cycle. It also keeps the fans off so warm air is not circulated. When the evap gets to about 20 degress or so, the sensor switches on the evap fans. If the fans are not coming on, either the sensor is bad or the evap is not reaching the proper temp to cause the sensor to turn on the fans.

Hope is helps to clear up some things and point you in a direction as to what might be going on.
