My name is Billy. Do you mind a test at the thermostat first? We would need to remove the top section where we can see the thermostat wires
locate R wire and G wire..this is the bypass for blower that takes thermostat out of the equation....short r to g with a U shaped wire....or remove and twist together...tell me if blower starts
Now short R to Y and tell me if outdoor unit kicks on
do you mind some test in the air handler?
and what is make/model
can you post a pic of the circuit board and close prox around it?
how many wires go to the motor?
Do you know if you have the ecm motor with lots of wires or a standard motor with 4-5?
thank you just pulling up schematic....with power on...thermostat set for fan on...any door safety switch taped down...if you hand spin the blower wheel does it try to run...spins and stops or is stiff?
do the spin test on wheel...and also if you have a meter put one lead on blue and other lead on yellow...240v present = bad motor
NO 240v present = bad board
We already know we have unit power and transformer as the outdoor unit runs...so it is down to board or motor
you have 2 main power wires coming into the air handler..what do they read?
what is black to red and not to ground...hot to hot
now getting toward the end.....there is a terminal strip r,g,t,ccc
Short r to g and tell me if any click on board.
ok you have a bad board.
R to y activates cool solenoid but r to g does not active fan relay.
You have correct voltage to unit.....it is just the relay is not closing to start motor.
You need to replace the fan board.
just rate service to remove from active list. I am avail for 30 days of followup after rating.
