Replaced this along with the two temperature sensors in my freezer. Fixed a defrost issue I was having. Replaced everything for less than the cost of a service call. You'll need some wire nuts and wire strippers, and it would be good if you had a little silicone to seal the wire nuts with. But otherwise, super easy installation. Plenty of videos on YouTube show you how to replace this.
