ensuring the heat exchanger reaches optimal temperature before air circulation begins and purging residual heat after the burner cycles off

A failed crankcase heater often presents as an open circuit or can cause tripped breakers if shorted to the shell

It provides critical flow regulation and safety shut-off within the combustion circuit

Easy Maintenance: The PopTop design allows for actuator replacement without tools or the need to drain the system

Compressor Protection: Prevents hardware damage by cutting power to the contactor before oil starvation or overheating occurs
