verify the thermostatic charge code to ensure proper pressure-temperature matching

and check for a dirty evaporator coil or blocked ductwork that could be causing heat buildup

the sensor should be open (infinite resistance)

eliminating the need to source separate electrical components for the reversing valve assembly

Reliable thermal logic in this Nordyne furnace safety switch protects the blower motor and heat exchanger from excessive thermal stress during demanding heating cycles
