Type of refrigerant

The pressure control will be fed a live from the thermostat and feed a live to the compressor relay

if the temp is 10f compressor is fine, just need a tune up, call a specialist.

How about a compressor model number. This will identify the Refrigerant used.

Hi John,

The symptoms do indicate a failed thermostat.

I am not sure where you could get a thermostat for this freezer but I would try contacting Norlake first. They may guide you to who has one or maybe they can sell you one. If it is a direct replacement it is something that you can do yourself.

THE FLAPER IS NOT GOING SHUT
REPLACE THE PLUNGER

Normally freezers are kept at zero. Most health departments will not allow the temp to be higher than plus 10. If you want to store ice cream, you need to be at minus 10 degrees to minus 15 degrees.

let me know if I can be of any further help.

Compressor 12/3 with 20 amp dual pole breaker. 220 VAC

Freezer 12/3 with 20 amp single pole breaker 120 VAC

The factory presets your temperatures to the MID / MID setting of 0ºF for the freezer.

Go here an find your model # for manual
