Customer Questions and Answers for Refrigerator Icemaker Cycling Thermostat by Whirlpool

Robert, the first thing to check and clean is the condenser coil, It's on the bottom of the fridge, and you'll need to remove the kick plate, and vaccuum and clean the condenser coils and surrounding area, as best possible. Also check the evaporator fan, it may be running at a slow speed and not moving the air properly. Thanks

Hello Joel. If the gears are not turning in the icemaker, and there is power to it, you will need to replace the icemaker WPW10190965 in the unit.

Hello Paulo. Based on the information you provided, it sounds like the thermistor WP2188820 is bad and will need to be replaced on the unit.

Hi Paul. I would use a volt/ohm meter part # MA-DM1 to assist. you in your diagnosis. At the face of the ice maker head, do you get 120 vac at the "L" and "N" ports of the meter ? If not then remove the ice maker and compare where the freezer wall/ ice maker female connector, make sure you have 120 vac where the black and white wire will hook up at the ice maker wire harness. If there is no voltage at the freezer wall connector then remove the freezer back wall and find the open wire behind there at the plug and electrically tracing the lost voltage . Use the supplied wiring diagram in the controls or behind the lower kick plate grill. Usually this is not the case. Make sure the black in-line- fuse in the ice maker wire harness is closed and not open. Make sure that you have the wire harness physically plugged in all the way. Once you have the supplied voltage, then there is a thermostat that has to close behind the head module that needs to be closed when the freezer temperature falls below 14°. If the thermostat does not sense the correct cycle temperature, then it will not close and allow the voltage to pass to the motor and let the ice maker head rotate and call for 7 seconds of water from the lower unit water valve. You need to set the volt meter already set up to read incoming voltage at the water valve. Use a # 14 GAUGE 3 " Long wire to strip off the insulation approx. 3/8" on each end. Push it into the I/Maker Head assy. on the "t' and "h" front terminals. With the bail arm down,watch the notched mark on the front white gear dial. It will rotate to the 4:00 position as then the 7 seconds then sends the 120 vac to the water valve below. Remove the wire when the mark rotates between 7 and 8:00. Also make sure the bail arm is pushed fully into the back of the head assy. or it will not call for water. As the ice maker thermostat is replaced then use a liberal amount of alumilastic cement part # WP4317852 on the face of the thermostat before it is finally placed on the back of the ice maker cube area. (This is where it senses the ice cubes frozen temperatures). Make sure the ejection blades are freely moving and not locked up . Use a dab of food grade white grease on the ejection back fill cup ares. Thank You.

Hello Ron. WP2304093 is the defrost timer. It is located in the control panel. You will need to test the heater WPW10140847 and thermostat WP2321800 and see if they read closed for continuity when cold. If they are good, you will need to replace the timer board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Hello. The thermostat WP627985 should read closed if cold or read open if at room temperature. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Hello Jack. This sounds like the cold control has bad contacts internally. The part number is WP2198202. Have a great day!

Hello Vahe. Check and make sure the fan motor in the freezer is running properly and the air returns in the top and bottom of the unit are not blocked. If all of this is good, you will need to replace the control box 2304102 in the unit. This is the control for the temperature in the refrigerator. Hope this helps.

Hello Don. On this model, you will remove the fill tube WP2256096 from the top of the unit. Then check and see if it is frozen. The fill tube will twist and pull out of the top of the unit. Hope this helps.

Hello Don. Check and see if the filltube is frozen. If so, you will need to thaw it out and order the water valve for the unit. Hope this helps.
