Product review (1 stars): Turned the knob to my unit's recommended position (3)
I had the exact experience as some of the other customers. The purchase transaction was OK and it arrived in a timely manner. However...

1. The sticker on the part is labeled "2198202", which is the required part for my Whirpool brand refrigerator.
2. Unplugged the unit, replaced the existing part with the new part, and put the unit back together (about 45 mins).
3. Inserted the knob and set it to the OFF position. Plugged the power cord to the wall outlet.
4. Turned the knob to my unit's recommended position (3). The unit started.
5. After about four hours, the freezer and fridge were abou 15F and 45F, respectively.
6. After about six hours, the freezer and fridge were abou 5F and 35F, respectively; should have switched OFF by now.
7. Turned the knob to a setting of 1, but the compressor kept going. Turned the knob to below 1, but not completely OFF. It kept going.

I messed with it for a couple of more days before I gave up. I reinstalled the old part (good thing I did not throw it away). While it is flaky, it somewhat works. This new piece of junk does not work at all. I suspect it is a cheap knock-off and not a genuine OEM part like the vendor claims.
