Just received a new defrost thermostat and tested the continuity as instructed with the ohm meter and glass of ice water. It did not show continuity - ohm meter reads O.L (overload I guess), does not beep. Ohm meter reads 1.3 Mohms. Could the thermostat be bad right out of the box?
ANSWER Hello Jon,
The new defrost thermostat could be bad out of the box, but it is more likely that it never got below the required temperature for it to close. It has to be at about 20 degrees before it will close. When it gets cold enough to close, it will read 0 resistance, just like touching your test leads directly together.
