Carlos H Highland , NY June 17, 2015 Refrigerator temperature was rising MY GE refrigerator temperature was rising. This not the first time that I have changed the defrost heater on this particular refrigerator. I had to replace it 3 years ago. I do recommend if you have a single glass tube to up grade to the double glass tube. It seems to be working just fine for now. Once again thanks Appliance Parts Pros for the speedy delivery.
