Coleman 13.5 fan not running

[Pirate1]

My 13.5 rooftop air fan wasn't running. I reached up and gave the fan a spin, it started running fine. How do I fix this? Thanks.

This is SOOO GOOOOD! Capacitor replacement is easy and inexpensive. We've had a lot of capacitor failures at home and I keep spares for Compressor and Fan. We've needed them. Came home from a trip to a hot house, twice. Both cases were Capacitor. For RV, I carry spares too, plus a Start Kit. Home unit doesn't use one.

There are VERY good capacitor prices on Amazon. Start kits are a little more expensive, particularly electronic "smart" ones like SUPCO SPP6e. In our hot FL weather, A/C failure is a trip ender.

Bingo. Replaced, working fine.

Mine, although about 20 years old started to squeal. I oiled it and it stopped for a day. But then it locked up all together. Bought one off internet, came with new run capacitor. Bolted right up. Bout 1/2 hour job. Not hard just a lot of screws and working on the roof that makes it a little tough. Think I paid 140 with shipping.

My old one felt like it was ok when sinning the fan, however after spinning the new one, I could then feel the difference.

The hard start cap is for the compressor, not the fan.

It spun real easy. Can I just buy one of those hard start caps on amazon?

You gave it a Spin...

Did it spin freely or did it seem like you got it "unstuck?"

If it moves freely takes what I'll call a fast spin to pick up and run, then good chance it's a run capacitor. Probably 7.5-MFD at 370 or 440 VAC.

If it felt sticky, you may be able to oil the bearings with Turbine Oil. The bearing on the fan end of the motor will probably be the sticky one. I had this happen, sticky bearing on fan end of shaft. Even taking the motor apart and crocus clothing the bearing, it'd stick again. Ended up with a new motor, about $100 on Amazon.

This is at least 7 years old.

I'm afraid it'll only get worse until it locks up for good. Is it under warranty yet? IIRR my Dometic had a 2 or 3-year warranty.

Loose wire or start capacitor.
