The freezer does not keep a constant temperature. The compressor kicks on when the door is closed, then it start defrosting in a day.
Hi there, just happened to see you as I was signing off. I am a refrigeration contractor, so this is something I would do. Mainly commercial units, same concept but different controls is all. Anyway, I will have to ask you questions as we go that you can get back to me on, with my user name. So, how old or new is the unit and when did you notice when this problem started?? We know that the compressor is working, but how good. It comes on and runs, but does it freeze at all before it starts to warm up? Once the compressor comes on when the cold control/thermostat calls for cooling, it should run until it reaches the desired temperature and the compressor will cycle off. Once it has frozen everything and shuts down, it will cycle on and off as needed to maintain this temperature. On a freezer, they have a defrost timer and defrost thermostat located in the system also. What I would like to know is the age and condition over all of the unit, to determine if maybe you have a small freon leak which does happen. Somethings you can check, is to pull it out to get behind it with the thermostat set to its coldest setting. With it unplugged, you should have a lower panel that you can remove to expose the compressor, the condenser coil, and coil motor. See how dirty this coil is as far as lint and dirt that has built up on the front of the coil. Clean it with a stiff bristle brush, not wire. It has to be clean for this motor to pull air back through it to keep the internal head pressures down on the unit. After you get all clean, plug it in as the stat is already to go and see if the compressor and this condenser fan motor comes on and runs. If the motor does not run, this will be your problem as it will be at fault and need replacing. Just spend some time back there and watch to see if the compressor continues to run. The air that you feel this motor pulling through the coil should be very, very, warm! If not, this indicates a loss of freon, and you have a leak. Try and time the compressor to see how long it runs before it shuts off only if the little motor is running, if you are up to it. It is difficult for me to tell you everything to check as we are limited on what you can do. I wish I were there. Anyway, let me know the things I have asked of you to do if you are able. You may just have a faulty thermostat control. We will go there later. Get back to me to let me know what is happening and if it freezes solid before it starts to defrost, and how far it defrosts, like all of the way.
PS, I have to run for an hour or so, but will check as soon as I return. Good Luck
