Product review (2 stars): The contacts within the unit is whats gone bad. By hitting part of the housing near the ...
This part worked but not correctly.  For 3 years after it was installed the refrigerator ran to cold. We had it set on the lowest setting winter and summe and leave it. Still occasionally froze things inside. Just under 3 years it started periodically not bringing  the refrigerator out of defrost. The contacts within the unit is whats gone bad.  By hitting part of the housing near the thermostat, triggers the contacts and the refrigerator turns back on. But only after the freezer is way above freezing  and refrigerator is 50 degrees plus. So I don't recommend this thermostat due to bad contacts within the unit. I purchased it for $39.00 and now its being sold for $17.00. With the price drop that tells me they are trying to get rid of this product.
