Product review (5 stars): Worth the price.
Had an issue for sometime where my Whirlpool stand up deep freeze started to frost up constantly during the humid summer.

During the winter it didn't have the issue as much or at all. I have actually manually defrosted the fridge about 3 times and finally bucked up and purchased this timer.

The old one wouldn't spin and I couldn't fix it.

Simply unscrewing the timer and unplugging it and then plugging in the new timer it worked flawlessly. It has defrosted the frozen coil and the huge chunk of frost that had encased the vents on the lower back portion of the freezer.

Worked like a charm and is well worth the cost.
