This freezer is a manual defrost. It seems to run for hours before shutting off, even with the t-stat at the lowest setting (1). Can someone tell me how to do a ohm test on the t-stat? What reading should there be at the different test temperatures?
Thank You.

Can you measure the temperature in the freezer and the refrigerator and post it here?
You can test the thermostat for continuity only and reading should be only "0" if it's closed and "∞", if it's open.

Gene,
thanks for the reply. My unit is only a freezer no fridge. I understand this t-stat is just an on and off type switch. However it must turn the compressor off and on at the set temperatures that are associated to the dial. So for example when the t-stat is set at "1" there should be a certain ohm reading because "1" might be set to go off when the box reaches say +10 degress. Then when the dial is at "5" there should be a different ohm reading thinking this setting would turn the compressor off at maybe "0" degrees, and so on. As you turn the dial upward, this should make the box colder, which means there is a different ohm reading at each number on the dial.
Please let me know. Thanks

This thermostat does not work by resistance. It works by the pressure of a gas inside the temperature probe. This gas pushes on membrane inside the thermostat causing the switch to close or open.
