Product review (5 stars): Perfect fit and function
My used GE Profile (TFX25PPBGBB) quit cooling and it turned out the freezer coil was a solid block of ice. I replaced the defrost timer, defrost thermostat, and this heater. The heater was a perfect replacement, fit exactly, and I just now ran the fridge through a defrost cycle and watch the heater glow red for 15 minutes or so until the thermostat clicked it off. Clearly it's working properly. Great price and I expect I'll get another 10 years out of this fridge now. Happy  :)
