Review: Cheap and it works perfectly - Went to get food out of my Criterion 7.0 cu chest freezer and everything was thawed. After looking over the internet found the relay is a very common fault. I was worried about getting this because the part number was different qp2-4r7md3 vs this one. I'm glad I got this because it worked perfectly. If your chest freezer goes bad try changing the relay it quick, easy and cheap.
