Gregory B Lynnwood , WA March 16, 2014 Lower freezer kept icing up and frig ran all the time Replaced the thermostat sensor and now it works great. Took about one hour including removing the built up ice on the coil. The changing of the sensor took all of 5 minutes. Thanks for the quick delivery of the part and I will use your site again. 18 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
