Alright, I need some help. In the last few days our fridge is no longer cold. We have GE side by side. The freezer appears to be working well. So at first I thought it was the damper between the fridge and the freezer. It was not. I tried several other things and I thought it was a malfunctioning defrost heater; however when l plugged the fridge in, I noticed that ice formed on the bottom half of the evaporator coils almost instantly. The top of the coil didn't freeze or even feel cold to the touch. Now I am starting to think there is a leak of coolant. I am going to have the defrost heater tested tomorrow but I have a nagging feeling there's a leak. Comments are appreciated. Thanks.
