It's amazing how this relatively inexpensive and easy to install part can get your fridge working again. The URC0210 is designed (according to the SUPCO website) for use in units with 1/3 to 1/2 HP compressors. About three weeks ago I put this on a 1/3 hp unit in a commercial soda cooler. It worked as it should and the cooler has been working fine ever since. My radiator didn't have a suitable place for it so I used zip ties to secure it to the frame and it seemed to work fine.
