Michael B San Antonio , TX March 15, 2014 Lower refrigerator area iced over. Blower frozen. Casing cracked from ice. Lisghts failed from ics intrusion. Ice maker failed from frozen lines near lower bulkhead. Replaced lower bulk head assembly. Most of the time required was to unfreeze the area and remove all of the ice and water. A hairdryer and a spray bottle with warm water were used for this. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
