SEALED SYSTEM REPLACING COMPRESSOR ON COMMERCIAL FREEZER

It is an overload protection device that cuts the power to the compressor if it draws too much current or overheats. Usually fitted close to the compressor body in a black box with the relay. Test by making sure you have continuity between the pins

Usually a blocked condenser fooling the thermostat into running overtime. Possibly thermostat fault but less likely

Thermo fuse has failed on the core plate, tells the freezer its cold enough to start blowing air, you can bypass it but not recommended. hope that helps, Russ

The fans are controlled with a clixon that has a cut in at 5 degrees, and cut out at 20 degrees. If the unit is running and the fans are not comng on then I would have to say you are out of freon. But your condensor fan could be running and the compressor NOT be running which could be a problem with your compressor. Find out if your compressor is running by taking an amp draw. If compressor IS running then you are low on freon. If the compressor is running and your evaporator coil is cold and your fans AREN'T coming on then your clixon is bad.
