Stopped cooling

Repair man that looked at it said it was the thermostat and that he would order the part. Waited two weeks with no word, so I ordered the part on line, got it the next day and installed it. The only hard part of the installation was getting to the three screws (located vertically in top of refrigerator section) to remove them. Simple three wire clip on changed unit. Total time took about 5 minutes. Refrigerator started cooling when plugged back in. Unfortunately, cooling again stopped within a day, so the original problem was more extensive than just the thermostat (so much for the service call diagnosis). Thoroughly pleased with part ordering, would do it again.
