Jay C Eagle , ID June 28, 2014 Appliance: Model GE M/N GFSL6KEXBLS Constant chiming from freezer temperature control kept changing terperatures! Called Sears repairman. He diagnosed the problem. Said that it would be $588 to fix. Or I could go online and buy this LED Light Board (p/n AP4416145) myself. Then install it. The part fit perfect and took me 10 minutes to do. Cost? $132 is all. Oh and the $55 callout fee. Read More... 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes Tools: Screwdrivers
