Is your Air Conditioner operational?


To check this, with the thermostat off the wall, short the Y and the RC terminals on the thermostats back plate. Your compressor and outside fan should immediately come on. If it does not, consult an HVAC professional.

Note: The duty cycle for the cooling compressor will require several minutes for ‘recovery’, that means you cannot do this test multiple times in quick succession.

Allow 5 minutes between tests for compressor recovery.
