Thermostat knob

lead connections

If the thermostat is working correctly, the multimeter should indicate continuity.

In addition, check the speed resistor with the multimeter. This resistor is used to set the compressor motor speed. Connect multimeter leads to either end of resistor assembly and set meter to resistance, Ω. This is a 277-ohm resistor. It should read between 265 and 280 ohms.

11.An additional test to use if a multimeter is not available:

Turn the unit off and disconnect both blue wires that were connected to the Danfoss module terminals “T” and “C”. Place the jumper wire across these terminals as illustrated.

Energize unit and if unit operates, this action indicates the problem may be a bad thermostat. Replace thermostat.
