Bought from LG (Kenmore Elite) for my fridge because the control board was failed and expensive. The fridge was actually just over 5 years old and hooked up to a cheap surge protector when it started having all sorts of icing problems - leading to a range of repairs from a new linear compressor, new sensors, a new capacitor core and a new control panel. While some of these repairs are obviously unrelated to power surges, I just wanted to take an extra step to protect my investment in a $3,500 unit that I had to spend another $1,000 on repairs after 5 years, which is much higher if there wasn't some was under warranty!) The question of whether a fridge needs a surge protector remains a widely debated one, and I agree that older fridges didn't have one. But having seen the control board on these new devices I would say yes it is definitely needed! I'll probably never know if this device actually helps extend the life of the device, but it's inexpensive enough to take a chance.
