Coils freezing. Defrost heater burnt out and not melting ice from coils allowing frig side to ge warm.

Watched video on site. Saw how simple it would be and ordered part. I already had experience getting into the coils because I was defrosting them with a hair dryer about every 4 to 6 weeks. Basically the repair is get the shelves and cover out, remove two screws,disconect two wires, hook the two wires to the new heater, replace it and the other parts and you are done. I replaced a single element with a dual element heater which only resulted in rerouting one wire. Insruction were very easily understood and the video made it even better. Just remember the video is replacing a dual element with a dual element. No problem with the change. Extra wire is sent if needed, but it was not needed. Thanks for saving me a bunch of money. I had a repairman look at it and he replaced the sensor and said if that didn't work that I would have to buy the whole circuit board about 150 to 200 dollars. Did it myseld for around 41 dollars part and shipping. Thanks a lot. Tommy
