Undercounter Freezer Not Freezing

[pob_1976]

Hi, I have an undercounter freezer that turns the thermostat on for 30 seconds and off for 30 seconds. The fast freeze function has no affect. Could this be the thermostat? Hope someone can help, cheers regards Paul.

if the freezer is jammed somewhere and it cant breath and has a condenser with fan the condenser might be clogged or mesure the amps on the compressor the windings might be shot and tripping on the overload and not the thermostat if it has a capacitor maybe that needs replacing. but if the fast freeze butn has no effect its most likely the compressor if you can save it do it if not replace it.

Thanks Tony for your reply, regards Paul.

An overload would stay off longer. I'm thinking low pressure control.

come to think of it normaly if its a houshold freezer the compressor wouldnt start after a 30sec. run unless the valves are shot in any case you would still need a compressor change.

compressor is siezing-not yet siezed hence ur getting 30 seconds of running then the klixon will reset after 20-30 seconds. household freezers dont have pressure switches

You sure it is running and not humming.

Possibly a ptc relay failure (danfoss) they do this sometimes
