We have two panels ready 3-door Kitchenaid refrigerators and both have had bad damper valves. One I saw how easy it was for a repairman to replace the first one I decided to order the part and replace it myself the next time the damper decided to act like a squirrel cage. Pull the small cover, unscrew two screws, pull the damper valve, unplug the old one, and replug the new one and reverse the process. Job is done!
