Customer Questions and Answers for Refrigerator Icemaker Cycling Thermostat by Whirlpool

Kurt, It'll be a little difficult, but doable. You'll need a short length(2 or 3 inches) of insulated 14 gauge wire, and strip both ends of the wire. Once you turn off the water supply, remove the white plastic front cover off the ice maker, and tape the freezer door switch down/closed. On the front of the mechanism plate at roughly the 4 and 5 o'clock position you'll see two openings labeled "T" and "H" insert the ends of the wire in the openings and hold it there until the rake arm starts to rotate, then remove the wire. The ice maker should cycle through to a complete cycle. You my want to repeat the test cycle again a few minutes later.
