Sorry that model number did not come through. What is the make and full model of the unit? And what are you needing help with, specifically?
That is a partial model, but need the full model to help with parts, etc. And what are you needing help with, specifically?
If the blower is not working, first thing to do is check for voltage to the motor. This can be done with a voltmeter set to volts AC. I'm not sure of your skill level, so let me know if you need further help with this part of the process.
If the unit is turned on to air conditioning, we should have 120 volts to the blower.
This is measured across the neutral blower lead to the Black or high speed motor lead.
Let me know what you find and we can proceed from there.
across the blower leads?
Yes, I know your unit has power. But if we are going to determine whether you have a bad board or a bad blower motor, I need to know if blower gets voltage on a call for cooling.
I understand that. But in order to determine what needs replacing here, I need this information. Otherwise I'd just be guessing.
It could be a bad board and it could be a bad blower motor.
$450-500 or more. Not cheap.
That's no problem. Question will remain open. Post back when you can.
