Review: Worked for my Danby DUFM085A2WDD1 Upright Freezer, 8.5 Cubic Feet - My eight-year-old Danby DUFM085A2WDD1 Upright Freezer stopped working. The compressor was hot, but it was not cooling. A quick internet search suggested that the start relay or the overload protector could be at fault. Danby's website showed these as being out of stock and cost over five times as much as desertcart without shipping. I found both on this listing for less than ten dollars and same-day delivery. This was a low-risk option compared to calling a repair person or buying a new freezer. I replaced the start relay and overload protector, and the freezer started cooling immediately after plugging in. N.B.: This is the three (3) pin start relay. Some are 1 or 2 pins. Take pictures as you disassemble so you know you are reassembling correctly. Open the box and install it immediately because some people do not open crushed boxes immediately and complain when they have missed the return window (can we give these reviews one star?). Even if this fails yearly, it is cheaper than buying a new freezer or getting a repair person. Review: perfect replacement - Perfect fit for our Avallon wine refrigerator. ## Features - ✅Package Content: 1 x Starter Relays 4.7 ohm 3Pin + 1 x Refrigerator Overload Protector 1/2HP. - ✅Please note that this product is only compatible with QP-02-4.7 relay with 3 terminals.
