Michael M Beloit , KS September 05, 2022 We had to manually defrost our GE profile fridge. Checked the heater and replaced a defrost switch since it was easy and not expensive. Still had the issue. Traded a couple of emails with AppliancePartsPros.com and decided the next step was the Main Board. This resolved the issue. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
