Note: Always check the fan blade on your fan assembly. Bad or unbalanced fan blades can cause premature motor failure due to vibration. If you are not sure what fan blade fits your fan assembly, call us at 734-326-3900.

To prevent premature motor failure, it is highly recommended you change your capacitor along with your motor. Capacitors out of tolerance can cause motors to overheat and prematurely fail. If you are unsure of what capacitor is required for your unit, please call us at 734-326-3900.
