Can a condenser fan run backwards?
Since the OEM capacitor in the unit is only 5 MFD, the new motor will randomly run backward and it will run with far less than its rated HP. Also, you should connect the new motor to run on LOW (red wire). These universal replacement condenser fan motors are not really multi-speed motors.
What would cause a fan motor to run backwards?
Watch out: yes it is indeed possible for some electric motors to run “backwards” following damage to the motor’s start capacitor or windings. We’ve had an occasional report of an HVAC motor running “the wrong way” or sometimes starting to run the the wrong way.
Which way should a condenser fan run?
From what we’ve learned on this subject, an AC condenser fan should spin in a particular direction. Your AC condenser fan generally spins clockwise. However, for clarity, you can check the electric motor data tag on your motor to see if it should run clockwise (labeled ‘CW’) or counterclockwise (labeled ‘CCW’).

How do I know if my fan is CW or CCW?
Look at the blade that is in the 12 o’clock position. One side of the blade will be resting on the floor and one side will be raised. – If the Right side is raised, then your fan is Clockwise. – If the Left side is raised, then your fan is CounterClockwise.
When replacing a fan motor in an HVAC condenser What else should you replace?
Every time you replace a condenser fan motor, you should also replace the A.C.’s run capacitor, which is a cylinder-shaped device that helps to start or run motors. To replace it, again take down all technical data on the unit, and note wiring colors and positions before removing it with a screw driver.
