Coleman A/C Motor Serviceable?
The Fan Motor in our Coleman Mach 15000 (Model 8335B8914 Serial 030218531) seized up tonight. I had a Zoom Spot Oiler onboard so up I went at 2313, no moon, Harbor Freight flashlignt. The oil wouldn't...

UPDATE! We got home from camping. Motor wouldn't run but about 8 hours before I'd have to go spray the motor shaft with WD-40 and add a couple drops of Turbine Oil. Today, I launched my repair campaign. Well, after I got a new compressor capacitor for the home A/C and got it cooling a very hot house...
The Motor is OUT but not Apart. It IS held in place with nuts, then another set of nuts takes the through-bolts out of the motor. There's no need to take the evaporator cover off, nor the interior grille down. What DOES have to happen was the Condenser Fan has to come off. It's plastic so even though there was rust on the shaft I could put a 9/16" open end wrench over the shaft, against the fan hub, and tap the fan off with a hammer against the wrench. With that done, it's possible to move the rest of the assembly to where the indoor blower cage will come out of the evaporator cover. Indoor blower came right off. Then disconnect wiring to remove the motor. So that's where that part of the project stands.
I also did Chris Bryant's A/C Cleanup/Tuneup on the two coils and washed both the fan and the blower cage. Blower was loaded with black gunk! I was able to position a cookie sheet to deflect water from going down into the coach. Sprayed the evaporator coil with Awesome and sprayed it clean with a garden hose. More dirt and gunk. Did same with the condenser coil. That's easier since there's no entry to the coach.
SOOO... Motor case pends. It squeaked as it came to a stop this morning before I started on the project. Right now it rolls over like a new motor. We'll see.
For now, The POOL!
