My freezer will not hold temperature. Only a year

3 star freezers are not storage freezers and will maintain frozen food for a short time only, They should reach -18c when closed but may come up in temperature quite rapidly when the door is opened. They are usually found as the cooling evaporator in fridges with freezer boxes in. Four star freezers are dedicated freezer storage space and will keep frozen food at the right temperature for some months.

Hose underneath is probably for condensation and defrost water. If the compressor is not coming on, there is a good chance it is the thermostat. There is always the possibility that there is a refrigerant leak and it leaked down over the 2 year period. This is where I would start.

The thermostat has a thick, bendy, copper or aluminium (non electric) conduction wire that goes from it, to physically connect to the internal metal casing.
When that lead becomes disconnected, the motor can just run, as the thermostat can't get a reading within the range it is designed to look for and control. It just hunts permanently for a reading.
Maybe this is not it, but see if anything came loose when you were storing the machine. If tempted to investigate areas that hold live 115V, always resist doing that and use a licenced electrician.

Both fans need to be running.

The condenser on top may be clogged. Or it may be sticking in a defrost cycle. I would be calling a different serviceman.

Check out their web site. Has parts lists.
You may not need to buy directly from them. Most of those compressors can be purchased from local HVAC supply houses that sell to the public. Get model and serial and brand off of the compressor and try W.W. Grainger. They do sell some compressors. Also, try Rick, at Restaurant Parts and More. He will need model and serial of the unit, and possibly the compressor. The more info the better. His number is 1-888-814-1110.Talk to Rick only.
Let me know if I can be of any future help.

It sounds like this is a a non DIY issue. there is really not much you personally can do.

Good luck!

First check for bunrt wires that can be grounded, then you can disconnect the compressor and plug the freezer and if doesn't blow the breaker , the compressor is bad ,if still blows them ,put the compressor back and try the fan , then try the other fan(inside one) or also could be the light switch, or the defrost heaters.

Sounds like a refrigerant restriction in the system. Recover the refrigerant, replace the filter drier and pull a deep vacuum on the system before recgarging.

Normal operating pressures will change as the freezer reaches the selected temperatures on the inside. Normals of minus 14 degrees on the inside would be around minus 4 psi on the suction and 150 pis on discharge. Now checking the pressure will require a set of guages that have been purged with the same freon before connecting with the suction line on freezer. If not purged the suction line will draw outside air into the system and cause freezing of air and moisture inside the capillary tube rendering the freezer inoperative, Hope this helps, Sea Breeze
