A/C Fan Problem

Have a Airxcel Products Rooftop A/C Unit, model #8335B8964, I assume is a Coleman, the fan will not come on, sits and hums, took cover off and it runs fine with a little assist, in the fan mode, but will not come back on when in the Auto mode. Removed cover for capacitors and found some oily gooey stuff, figured it was the start capacitor, 88-108mfd, ordered a replacement, still wont crank the fan, noticed a resistor across the terminals on the old capacitor, that didn't come with the new one. My question is does this resistor make a difference or could it just be the fan capacitor(1499-5461) or if any other ideas I would appreciate the comments.
Thanks

That resistor for the capacitor is just a bleed resistor. It doesn't have anything to do woth the functionality of the capacitor. Its only job is to keep you from getting shocked if you accidentally touch across the terminals.

Boy, you sure know a lot more about this stuff then I do. My only comment is did you replace the right Start Capacitor? There would be one for the compressor, I'm not sure the fan motor even has one but, it might. Maybe you got the capacitor for the compressor changed and not the one for the motor. But, as I said you seem to be more up on this stuff them me.

PM me if you don't get the problem figured out soon and I may be able to direct you to the right place that can help you out.

So . . . what was it?
If the fan hums but doesn't blow it's two things: either bad capacitor, or bad motor. Plain and simple.

I agree. I maybe wrong, but generally speaking, small fan motors don't have external capacitors. They generally don't need them. I work in heating, cooling, and refrigeration and I normally only see capacitors on bigger motors.

These ACs do have capacitors. Motor start, compressor start, and compressor run.

I replaced the start capacitor and it didn't solve the issue, I am waiting for the Fan Capacitor to come in the mail. The fan runs fine as long as I keep it in the manual mode were it runs all the time and I can control the temp with the t-stat but if we have a power outage it has to be jump started withe the pinky. How ever we were gone last weekend and must have had a short power blip because the microwave was flashing but the fan motor was still running, the power must have come back on, while the fan motor was still turning enough, that it didn't need the small jump start. Will let ya'll know it the Fan Capacitor fixes the problem!!
Thanks for all the input!!

See, and that's why I'm here,, to learn. I too was thinking that fan motors don't often have start capacitors but, jrsilvas set me straight. I suppose in this application where a wind could be blowing against the fan making it hard to start they then use a capacitor.

Your fan motor does have a capacitor. It is definitely the problem. When you turn the fan by hand and it starts that is an indication the capacitor is bad. I am quite sure your fan will run once you install the new capacitor.

It's a fan start capacitor, just to clarify for anyone else thinking this is their issue.
The fan needs a start capacitor to get it going, then runs on it's own. That's why spinning it by hand worked.
The compressor needs a capacitor to get it to start AND to stay running.
