York H2RC048S06A Fan Needs Push, But Already Replaced Parts

[Budget Appliance Repair]

? I Wonder if the existing dual capacitor was rated correctly for the new motor that was installed a year ago?

If it wasn't and the new motor called for a different capacitor rating, what would the ramification be to the new motor

and/or the old capacitor if it was in-fact able to make it start and run correctly for the last year that it has been working?

Did you remove the drain plugs from the down-facing (shaft) side of the motor? I've seen many motors fail in their first year because the drain plugs weren't removed. If the capacitor is good the motor has to be bad (assuming you wired it correctly). If you replaced a 3-wire motor with another 3-wire motor you can't get it wrong.

A word of warning for anybody else....stay away from chinese HVAC parts; especially anything labeled "Packard".

The replacement motor was the same make/model as the original and the new and old caps were the same exact rating. Granted, something could have been defective, but I was careful to match the specs on the labels. Certainly worth mentioning, though.

The bottom of the motor has two holes in it, but no plastic plugs of any kind that I could see. The motor has a wiring harness connector, that plugs only one way into the rest of the unit, so it wouldn't be possible to wire it wrong, as it is "plug and play".

Is there a better replacement motor than the AO Smith F48J66A48 that is in the unit?

I just remembered something about that York/Luxaire/Coleman unit you have; the fan wire to the capacitor and the compressor start wire are both shades of brown. What posessed those York bozos to do that escapes me. Make sure the brown wire going to the quick connector is the one connected to the fan terminal on the capacitor. I got my two browns reversed before on one of those units and the compressor actually started and ran with it wired wrong (kickstart installed) but I got a call back on it the next day and discovered the error. Nothing damaged, thank goodness. I still think you have a bad motor if the capacitor is new. Having said that, if the capacitor is chinese get another (different) one first. I've had great success with the Amrad capacitors. Only one failure in 2 years. I won't use anything else.

As for the quality of that motor? Most manufacturers aren't going to spend top dollar on an OEM fan motor. AO Smith makes a decent motor. Make sure rain water isn't pouring down directly onto your motor.
