How to replace Refrigerator Condenser Fan Motor. The condenser fan was covered with black grease mixed with accumulated dust and dirt. It also started making humming noise. Removal and replacement was easy. When cleaning the greasy deposits off the fan blade I bent them ever so slightly without knowing it. This caused the blade to rub against the housing when re-installed. It took a few minutes to figure out what happened. Tweaking the angle of the blades every so slightly solved the problem. Refrigerator functioning normal now and quiet. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
