I have an older Jenn-Air JRSD209T that stopped defrosting. I replaced the heating elements and replaced the defrost thermostat. Tested the timer and it works properly. After replacing the two components the defrost heater will still not come on.

I tested the new heater and it has good continuity and will work if I bypass the defrost thermostat. (IE I disconnected the thermostat and jumped the two terminals. When I did this I could get the heater coils to heat up.

I’m at a loss as to my next step to try. My only thought is the new thermostat I bought is bad.

What temperature was the defrost thermostat at when you tried to force a defrost?

That thermostat is a switch that opens an electrical contact when it gets warm, to stop the heater after a defrost is complete. It will not reset to the closed position again until it gets cooled to around 20 deg. F.
