Please provide me with model on the indoor unit.Sometimes blower is controlled by different relays in ON mode, Cool Mode and Heat mode. May be a relay in unit that is not clsoing
Ig everything is in a packaged unit outside(No indoor) give me model on that unit
Looking at manual wiring now
Best I can tell the thermostat should energize the blower through the G terminal in both COOL and FAN On modes.Heat speed is energized through a separate relay for low speed.
Tell me which thermostat you are using and lets see if it has any settings we might check.
See diagram G energizes relay to turn on blower
Model on the Emerson?
The thermostat is responsible for making both Y and G terminals on call for COOL
It is not the blower. If you can turn thermostat to FAN On and make blower work, that tells us motor is Ok and that when G is energized, blower responds. Issue is that thermostat is not energizing G terminal on call for Cool as it should
Let me ask you this question. Goodman used what is called an ECM motor on some of these units and a PSC motor on others. Can you look at the blower motor and tell me if your motor has a capacitor and only 4 or five wires or if motor has a bell on end od motor?
I have to step away from desk but will return shortly.I will open this to other experts until I return.If no one picks up the question, we can continue when I return
Sorry about the delay. Just got back.
I have done a bit of research and determined that the E in your model indicates this unit uses an ECM (variable speed motor).
The motor is High voltage AC powered but low voltage controlled through the computer board.
You issue is going to be either the bell control on the end of the motor or it is going to be the control board.
However to troubleshoot is going to require a special tool called an ECM motor tester. I am including links to verify this and instructions for troubleshooting.If you have or can get the tester I will be happy to guide you in determining if the bell controller or the board is the culprit.
Here is a link to the tester.
Let me know if you have the tester or can get it and we will go from here.
