Need help with a Whirlpool side-by-side refrigerator with the icemaker in the door. Ice is being made and water dispenses fine. Starting about 2 months ago, I needed to press the ice lever several times to dispense ice. Now it's getting to be kind of a pain and I would like to fix. Should I replace the motor or the solenoid or something else? If you press the lever more than one time, you usually get ice to dispense (seems to be a random number of presses sort of like Pavlov's dog experiment).
