Dan H Pittsburgh , PA June 18, 2022 Buzzing noise from Whirlpool refrigerator. Replaced the condenser fan with a new one, noise is gone entirely. The hole in the middle where the fan connects to the motor must have gotten loose with age and as a result started buzzing due to not being fit securely. New one resolved the issue Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
