You need a multi-meter to do this. The temp.control is just a switch that closes on temperature rise and opens on temperaure fall (or when it reaches the desired temperature). Using a meter set on ohms coneect to the 2 prong ends of the temp. control. Set the temp. control on off. You should not have any ohms because hte temp. control is open (no continunity) now set the temp control to 2 or 3 and it should close (the meter will read ohms or continunity)
if it does then the t'stat works. The only other exception is the temp. control will sometimes (this is rare) not properly sense temp. for example, it fails to sense zero degrees and it will either stay on too long to shut off too soon. I only seen this happen like twice in 20 years. but more or less this is how you do it!!!
hope this was helpful
Can you short the two wires together from the temp control to test the operation of the compressor? I have an issue were my freezer is completely dead, with the exception of the interior light. I replaced the relays on the compressor but still nothing. I think I may have a bad temp control, but I dont own a meter. Not sure if I should keep ordering parts for my 12 yr old kenmoore upright freezer.
