John B Greenleaf , WI June 30, 2014 Automatic defrost wouldn't work causing ice build up and loss of cooling Went through testing procedures described & found likely cause to be the defroster heating element. Easily found replacement part, ordered & had it within two days. Very clear instructions were included longest part of repair proved to be waiting for the ice build up to melt. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
