Is it possible to reverse the rotation of a fan motor by installing a new capicitor? The motor draws air through the top of the unit and forces out through the condenser, instead of drawing it through the condenser and out the top. The motor rotation is backward if you look from the rear of the motor. I have never noticed this before. I had a contractor put a new capicitor in today, and when he started it up, he noticed the motor was running backward. It is the motor the unit came with, and has only 3 wires and is not reversible. The unit ran for awhile, but the fan motor quit. After allowing the unit to cool down, it is running again. By the wiring diagram, it is wired correctly. The capicitor that went bad was a combination (1 capicitor) unit. They installed a large and small capicitor to replace it. I have never heard of a motor changing rotation unless it was a reversable motor. I have had no problems with this unit, and now it wont stay running.
