I'm workin on a GE MOD# TFX26KRDA-WW and the problem is the unit won't defrost and there's tons of ice build up in the freezer. I thought it was the control board, but when I went there I took out the heater element and it was completely destroyed. No continuity and in addition to that one part came right off. So I know the element is bad but Im wondering if the thermostat can be too. I couldn't get to it because of the ice, but I think it's in series with the heater I should of hooked the leads of my multimeter to both wires and checked for continuity. What do you guys think?
