The Whirlpool Ice maker is one of the most common ice maker in refrigerators today, several appliance manufacture use this ice maker in their refrigerators. Repairing your own Refrigerator or Ice maker is relatively simple, first lets take a look at the style ice maker were talking about.
To gain access into the timer assembly the head of the ice maker needs to be removed, with a small screw driver or putty knife pry the plastic head off. With the front of the ice maker removed the you will see the face of the timer, it will look like this.
Now that the front of the ice maker is off and you can see the timer lets get started. You will need a jumper wire in order to bypass the ice makers internal components, the jumper wire should be insulated voltage will be going through the wire while your holding it, the insulation will protect you from a 110v shock. I use a basic wire stripper and copper wire for a jumper.
With the access to the ice makers jumping L to V will send direct voltage to the water valve on the refrigerator this should send water up the line through the fill tube and into the ice maker. Note the fill tube often times becomes frozen stopping the water in it’s tracks. Check the fill tube in the rear of the refrigerator for frozen ice if none is found and L to V is jumped the valve is most likely at faulty. To verify a volt meter will be needed, with L to V jumped and the volt meter tips on the solenoid 110v should be present. If power is present and the fill tube is clear, double check that the water is turned on, if so the valve is to blame.
