Review on 🧊 LONYE W10225581 Defrost Thermostat for Whirlpool Sears Refrigerator – Compatible with WPW10225581, AP6017375, PS11750673, PS237680, 2321799 by John Taylor

I wish there was a description of the opening and closing temperature points, but that's not important. I put it in a working freezer for about 30 minutes and the contacts closed with continuity. When warming up, the contacts opened as expected. My existing thermostat turned out to be fine, but this purchase was worth the purchase at a reasonable price. My next purchase was a defrost timer which solved my problem.
