Typically, that's what happens when the sleeve bearings wear out. Grab the motor shaft and check the slack up and down, there should be none. The gap between the rotor (the part that spins inside the motor) and the stator (the electrical windings that create the rotating magnetism on the rotor) is tiny. Any wear in the bearings let the two parts touch, this creates heat and the resulting metal expansion causes the parts to rub beyond the ability of the electrical force to continue the rotation. When the motor stops turning, the amps rise to 5 times the normal rated amps.

Running capacitor is likely the problem if the motor is not worn, (shaft play).

They are a cheap fix if that is it.

This probably didn't help. Dirt dobbers.

knock off all that dirt and see what the capacitor connections and if the capacitors look like and are swelled any at all

Yup. Cleaned it all up, capacitors look ok but I ordered a run capacitor with the motor. $8 well spent.

Well, the fan motor and capacitor showed up today so I got those installed. Put all the covers back on after sealing up every little hole to be found and cranked that dude as cold as it would go. In about an hour it went from about 90 in the camper down to about 78. Thanks for all your input.

Well done, I guess you found the hole the mud dobbers were coming in. they will also try to get in around the water heater vent outlet if the screen has any openings. At the lake house we had to put a pair of pantyhose around the motor because it was a drip-proof frame and they built nests inside it on the start switch.

Yes, I've cleaned dirt dobber nests out of the furnace exhaust, the water heater flame tube, the water heater control panel, the refrigerator mechanical panel, the rear bumper(black water hose storage), the battery box, the propane tank stand, and various locations underneath the camper. So it wasn't too surprising to find them in the condenser, but was surprised they found their way into the control panel for the a/c. It's done now though.
