Not the best, but it works. Could be better in some aspects.

The defrost thermostat fixed the issue with my refrigerator not cooling properly. Happy with the results and saved me from buying a new fridge.

Great replacement part for my Whirlpool refrigerator. Easy to install and works perfectly. Very satisfied with the purchase.

Took a bit of effort to install and didn't see a significant improvement in performance. It's working, but not sure if it's worth the hassle.

This fridge is decent for the price. A few minor issues but overall satisfied.

I've always been a fan off Whirlpools refridgerators and this one did not disappoint. Lots of space and the ice maker is a nice touch. I would recommend this to anyone looking for a new fridge.
