“these relays have been my go to, when working on refrigeration and freezers, have good results with them, and no problems with them”

“About a year ago, I spent a lot more money on an allegedly OE “Jahwa” part for my kitchen side by side Samsung fridge. The relay fixed my problem but eventually failed open and the compressor would try to run constantly. I had wisely purchased a spare relay – but also purchased this two pack as well. I tried this out and my fridge has been back to normal for the past 2 weeks. Compressor runs occasionally like it should, fridge maintains 0 degrees on freezer side and 38 on fridge side. Very happy!”
