Defrost thermostat open/closed
I ordered and received a defrost thermostat and wanted to test it before putting it in. The circuit is open (infinite res) out of the box at room temp. I froze it with spray just to see if it was backwards, and it stayed open. I put it under a heat lamp and at 84F it stayed open.
Then I returned it because I thought it was bad. I received a new one and it tests the same way. I was assuming that the thermostat should be open until it gets too cold, then should be closed, to turn the heater on. Am I mistaken?
