Pablo B San Antonio , TX September 04, 2015 Appliance: Model MZD2868GE The freezer compartment was icing up and not allowing for the compartments to stay cold This is the third time I have replaced the defrost control board in 12 years. It is known to be defective. APP has always been faster and cheaper than sears for replacement parts. Hopefully the manufacture will fix the problem in future replacement parts. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
