Safety tips

When working on any appliance, always keep safety first to avoid personal injury or damage to the appliance or its parts. Here are some tips to keep in mind:

• Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by eliminating any risk of electric shock. 
• If the appliance has recently been used, give it plenty of time to cool down before working on it. 
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Work in a well-lit area so you can see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with wet hands. Make sure the work area is completely dry.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part. 
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Always take photos or make a note of wiring terminals or other connections before disconnecting them to make reassembly easier.
• Don’t test live voltage with a multimeter if you’re unfamiliar with how to prevent short-circuiting.
• Consider wearing safety glasses and/or a dust mask when working with chemicals, dust or a large amount of debris to prevent irritation or injury.

How to test and replace the Whirlpool-built refrigerator’s modular ice maker

Follow these steps to test, diagnose, remove, and replace the Whirlpool-built modular ice maker (WPW10756907) in your refrigerator.

Step 1. Access the ice maker

1. Disconnect power by unplugging the power cord or turning off the circuit breaker.
2. Open the freezer door and remove the ice bin.
3. Locate and remove the two Phillips head screws securing the outer frame for the ice maker and ice bin to the door.
4. Take off the outer frame and set it aside.
5. Use a flathead screwdriver to pry off the cover on the head of the ice maker.

Step 2. Test the ice maker

LIVE VOLTAGE WARNING: For this test, the refrigerator needs to be plugged in and powered on. Please be very careful to protect yourself from electric shock, which has the potential to cause serious injuries. Don’t ever test live voltage if you’re uncomfortable using a multimeter.

1. Tape down the freezer door switch so the unit remains powered during testing.
2. Identify whether the ice maker uses a bail arm or an ice level sensor.
3. If it has a bail arm, lower the arm into the down position.
4. If it has an ice level sensor, tape down the flapper door without blocking the sensor beam.
5. Set the ice maker’s on-off switch to the ON position.
6. Plug the refrigerator back in.
7. Set the multimeter to AC voltage mode.
8. Locate the L and N ports on the head of the ice maker.
9. Insert the multimeter leads into these ports to check for 120-volt AC.
10. If the correct voltage is present, remove the meter leads and take the tape off the door switch to cut power.
11. Identify the T and H ports on the ice maker head.
12. Insert both ends of a jumper wire into these ports.
13. Hold the door switch down and observe whether the ice maker begins cycling within five seconds.
14. If the ice maker does not start cycling, release the door switch, reposition the jumper wire, and try again.
15. If the ice maker still does not respond, replacement is necessary.
16. If the ice maker begins the harvest cycle, watch its fingers and remove the jumper wire just before it reaches the 10 o’clock position.
17. Let the ice maker complete its cycle and check whether the ice maker’s valve activates and fills the tray.
18. After the cycle is complete, wait 30 seconds, then release the door switch.
19. If the ice maker fills and the freezer temperature is correct, the ice maker needs to be replaced.
20. If the ice maker does not fill, unplug the refrigerator.

Step 3. Check the ice maker valve circuit

1. Remove the harness cover at the top left-hand corner of the door.
2. Disconnect the ice maker’s wiring harness from the door.
3. Set the multimeter to measure resistance (Ω).
4. Insert the meter leads into the ports for the Tan and White wires on the harness leading into the door.
5. Check for a resistance reading between 100 and 300Ω.
6. If the expected resistance is present, replace the ice maker.
7. If resistance is not within range, inspect the wiring through the door, the ice maker valve, or other electrical components.

NOTE: Generally, for every 1 degree in temperature difference, 2 Ohms could be added or subtracted. If the temperature in your home is cooler, resistance would be subtracted.

Step 4. Remove the ice maker

1. Unplug the refrigerator.
2. Note the placement of insulation pieces around the ice box frame and remove them. Taking a picture before removal may be helpful.
3. Locate and remove the four ¼” screws securing the auger plate.
4. Remove the auger plate. If the auger motor spring is inside the auger plate, return it to the auger output.
5. Remove the inner ice bin frame from the door.
6. Locate and remove the four screws securing the ice maker to its bracket.
7. Carefully remove the ice maker and wiring harness from the door.

Step 5. Install the new ice maker

1. If a replacement ice maker and harness are available, proceed with installation. If not, order the replacement part WPW10756907 from appliancepartspros.com.
2. Position the new ice maker onto the bracket and secure it with screws.
3. Thread the ice maker harness through the harness cover and connect it to the door.
4. Snap the harness cover into place and secure the remaining wires in their designated tabs.
5. Reinstall the inner ice bin frame and align it properly.
6. Place the auger plate back into position and reinstall its screws.
7. Reattach the insulation panels in their original placement.
8. Secure the outer frame back onto the door.
9. Insert the ice bin back into place.
10. Remove any tape from the switches.
11. Close the freezer door.
