Product review (5 stars): Excellent replacement for my Whirlpool frig
Excellent replacement for my Whirlpool frig.  Wasn't sure if needed to replace the thermostat or some other component but after reading some of the other reviewers comments, I decided to try this first.  Before replacing this part, the frig side would warm up to an unsafe temperature, maybe 50 - 60 degrees, while  the freezer side seemed to hold the correct temperature. When I tapped on the thermostat housing, I could hear the frig motor start up again.  Frig side would then cool down to the normal 35 degrees, but only for a day or so, then begin to warm up again.  Seemed logical it was the thermostat and as it turns out, it was.  It's been almost a year since I replaced this part and frig has been running perfectly.  There was a video online that showed exactly how to do the replacement.  Made it super easy and fast!
