Keith G Sanford , ME November 01, 2022 The refrigerator making ticking noise when compressor turned on. After taking the back off my 16-year-old fridge. I discovered the ticking sound was coming from the condenser fan motor. The shaft was loose and wobbling when running. A quick, easy fix that took about 30 minutes. Cheaper than a new fridge! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
