2. Initiate a demand from the thermostat and
check the voltage between the common and the
appropriate motor terminal (1-5). ("G" input is
typically on terminal #1, but always refer to wiring
diagram.)

present, check the demand from the
thermostat. Also check the output terminal
and wire(s) from the terminal strip or control
relay(s) to the motor.
