I'm at a loss. I have tested the defrost timer for continuity, which it has. I manually turn the dial and each cycle does what it's supposed to. I tested the defrost thermostat and it had continuity at freezing temperatures and no continuity at warm temperatures. I tested the defrost heater for continuity and it had it and it had an ohm reading of 33.6. And yet, when I turn the timer to defrost (and the thermostat is freezing) the heater doesn't come on. Any wizards out there know what I should try next. Thanks so much.
