Montgomery Wards Refrigerator ice maker not working

If your refrigerator ice maker is not working, start with the parts that fail most often and work down the list. The main control board is the top culprit since it controls voltage to the ice maker; inspect the board for burn marks and use a multimeter to see if the ice maker is getting power. Next check freezer temperature; if the freezer is warmer than about 10°F the ice maker will struggle, so set the freezer between 0 and 5°F for reliable ice production. A faulty water inlet valve or low water pressure (the valve needs about 20 psi) is another common cause, so test the valve for power and flow. If those check out, the ice maker assembly itself, a bunged dispenser solenoid, or a frozen or damaged fill tube can keep the mold from filling. You can thaw a frozen fill tube with a hair dryer and use continuity and voltage tests to narrow the fault.

01 - Montgomery Wards Refrigerator Main Control Board

The refrigerator's main control board controls the voltage being sent to the ice maker. If the control board is defective, the ice maker may not work at all. You can inspect the board for signs of damage or a shorted component. You can also use a multimeter to determine if voltage is reaching the ice maker after reviewing the refrigerator's wiring diagram.

02 - Freezer Temperature is Above 10 Degrees F (-12C)

If the freezer temperature is above 10 degrees Fahrenheit (-12 Celsius), the ice maker will not produce ice cubes efficiently. The freezer temperature should be set between 0 and 5 degrees Fahrenheit (-18 to -15 Celsius) for the ice maker to work properly.

03 - Montgomery Wards Refrigerator Water Inlet Valve

The water inlet valve is an electrically-controlled valve that opens to supply water to the dispenser and ice maker. If the water inlet valve is defective, or if it has insufficient pressure, it won’t allow water to flow through. As a result, the ice maker won’t make ice. The valve requires at least 20 psi to function properly. Make sure that the water pressure to the valve is at least 20 psi. If the water pressure is sufficient, use a multimeter to check for power to the water inlet valve. If the water inlet valve has sufficient pressure and is getting power, but the ice maker won’t fill with water to make ice, replace th...e water inlet valve.
Highly Likely

04 - Montgomery Wards Refrigerator Ice Maker Assembly

One component of the ice maker assembly might be defective. Since many of the ice maker components are not sold separately, you may need to purchase and replace the entire ice maker assembly. Before replacing the ice maker assembly, check the water inlet valve, water line, and fan. If none of these parts are at fault, and the freezer temperature is at least 15 degrees Fahrenheit, replace the ice maker assembly.
Common

05 - Montgomery Wards Refrigerator Dispenser Solenoid

The dispenser solenoid opens a door flap to release the ice and then closes the door flap once the dispenser finishes dispensing ice. If the dispenser solenoid is defective, the dispenser door won't open. To determine if the dispenser door solenoid is defective, use a multimeter to test it for continuity. In addition, check the dispenser actuator pin to ensure that it moves freely. If the dispenser door solenoid does not have continuity, or if the actuator pin does not move freely, replace the dispenser solenoid.
Common

06 - Montgomery Wards Refrigerator Fill Hose

If there is low water pressure coming into the refrigerator, or the water inlet valve is defective, the ice maker's fill tube can become clogged with ice and prevent water from entering the ice maker tray. You can use a hair dryer to thaw out the frozen fill tube, but you should confirm the home has sufficient water pressure and the water inlet valve is functioning properly. If the fill tube appears damaged, you should replace it with a new fill tube.
