Product review (5 stars): Great inexpensive replacement part to fix Samsung defrost problem.
An inexpensive defrost sensor for our Samsung fridge which was having a common problem where the drip catch pan under the defrost coil ices up and water accumulates and freezes in the crisper drawers and in the bottom of the fridge. Sensor is easy to install and is working well. Watched great YouTube video explaining the process.
