Cleaned the contacts of the switch with some DeoxIT and the contacts of the switch read open when pushed to the off position, and they read 0.0 ohms when on so clean bill of health. Now if the thermo element inside still works i'll be in business.

Update: checked the termo switch by putting the tube in the freezer and setting switch between off and full blast cold. i closed the freezer and and the switch clicked about 30 seconds after i closed the freezer door. i removed the tube from the freezer and about 30 seconds it clicked again. so that function check is good.
