York HP installed in 2003. AC supposed to be running. We started to hear clicking while the outside unit was running but the blower was not. I went under the house and checked the little fuse(It was Ok). I checked to find the source of the clicking. It is coming from the fan motor trying to start. The fan tries to move but won't move more than 1/4 inch with each click. The fan would turn fairly freely with help but not keep going. This motor has two plastic plugs to hook up the bundle of wires. After several minutes, a sharp alarm sound was heard(beep beep). The green light on the circuit board was flashing while the fan was trying to start. The outside unit was running and the air handler coil began to freeze. We tried the "fan on" setting with the same results. I did some research and went back under to look for a run capacitor. There was none that I could see- none on the fan housing and nothing on the circuit boards that looked like a capacitor. Everything I read said there would be a capacitor.
What should I do next?
Is there a capacitor I can't see?
What does the green flashing light mean when the power was on?
What does that alarm sound(beep beep, like a microwave oven) mean?
I will appreciate any worthwhile advice.

Thanks. I am not too familiar with the terminology. Does PSC refer to a single speed motor with a run capacitor? Can I have my motor(If it checks out OK) equipped to run single speed or must I have a basic single speed motor installed? I need to have some understanding of this before I call a local pro.A unit that old, I would just stick a PSC in it and be done.

If the motor is good, usually is, but the module bad, I'd repair or replace the module.A unit that old, I would just stick a PSC in it and be done.

Check your warranty. I don't know about york but most of the ECM motors I deal with have a 10 year part warranty. Changing a module on one takes a half hour so the labor won't be much.

It should have a 10 year warranty. But, 2003 was when they were just going to the 10 year, so his may not be covered.

Model number of indoor and outdoor units may help to select replacement blower motor.
Yes a new different one will have to be installed.

A module replacement is about the same cost as a blower motor replacement. And doesn't need the relay addition that converting to a PSC motor would.
Plus, if he's in a humid area, he may not like the humidity increase he could get from going to a PSC motor.

I just realized he was talking of the indoor blower instead of the condenser motor. In that case I would definitely go back with original parts.

Thanks for all the input. The only warranty now is on the compressor. The rest ran out at 5 years. What is the official name of the "module"? Fan control module?

No, its an ECM module, and its OEM only.
