My Duotherm rooftop ac unit (57915-531) doesn't
My Duotherm rooftop ac unit (57915-531) on my tent trailer doesn't spin (blow air) properly on it's own. I can help start spinning the fan by hand and it works for about 5 mins, but then stops and trips the breaker. The compressor seems to kick in when it's spinning. Is the motor just shot? Someone said spray some wd40 on the shaft(axle?), that didn't seem to help.

Hello :
It seems that the motor armature is burn. Dissemble the unit, remove the motor. Loosen the bolts running from end to end of the motor and with emery cloth, clean the small metal plates on the ehd of the armature. They should be bright copper color. If the armature is burnt, they will be dull brown. The other thing is to replace the brushes in the motor.
good luck .
