Product review (5 stars): The old one past the multimeter test, but still needed to be replaced
Our Whirlpool ice maker was overfilling, spilling ice on the floor every time the door opened. I bought a multimeter to check the resistance of the old thermostat. The old one was exactly in range, so it did not seem to be a problem with the old thermostat. I got a little desperate so I went ahead and bought this replacement thermostat anyway. It fixed the problem perfectly. My ice maker is back! I'm not sure why the old thermostat doesn't work but I'm just grateful for this relatively cheap fix.
