Admiral Refrigerator Loud Jackhammer Noise When Making... | appliancefaults.com

Technical Background:

The refrigerator's main control unit (MCU) initiates the ice-making process by signaling the water inlet valve to open, filling the ice mold. Once filled, the ice maker freezes the water. The MCU then activates the ice maker motor to eject the ice cubes. Voltage paths are crucial for the ice maker's operation and include 120V AC circuits for the water valve and motor.

Symptoms:

The homeowner observes a loud, repetitive jackhammer-like noise emanating from the refrigerator, specifically when the ice maker is cycling to produce ice.

Possible Causes:

Loose or broken ice maker components
Water valve malfunction
Ice build-up interfering with ice ejection
Worn or damaged ice maker motor
Foreign object lodged in the ice maker assembly

Solution:

1

Disconnect power to the refrigerator at the breaker panel. Verify 0V AC at the outlet with a multimeter.
2

Remove the ice maker cover (usually secured with screws or clips). A 1/4-inch nut driver is helpful.
3

Inspect the ice maker assembly for loose screws, broken plastic parts, or ice buildup. Manually rotate the ice maker gear to check for obstructions.
4

If ice build-up is present, use a hairdryer (on low setting) to gently melt the ice. Avoid using sharp objects that could damage the ice maker.
5

Check the water valve for proper operation. Disconnect the water line and test the valve with a multimeter for continuity when the ice maker calls for water (approximately 120V AC). If no continuity, replace the water valve.
6

If the motor is suspected, carefully remove it and test its windings with a multimeter. Compare the readings to a known good motor if possible.
7

Reassemble the ice maker, ensuring all components are secure. Restore power to the refrigerator and monitor ice maker operation.

Safety Warning:

Always disconnect power to the refrigerator before performing any repairs. Use Lock-Out Tag-Out (LOTO) procedures to prevent accidental re-energizing of the circuit. High voltage components are present; exercise caution when testing electrical circuits.

Prevention:

Regularly clean the ice maker and ice storage bin. Check the water filter every 6 months and replace it as needed. Ensure the freezer temperature is set correctly (around 0 degrees Fahrenheit) to prevent excessive ice build-up.

Expert Tip:

Some Admiral refrigerators have a service mode. Press and hold the freezer temperature 'down' and refrigerator temperature 'up' buttons simultaneously for 5 seconds to enter service mode. You can then initiate an ice maker test cycle.

Frequently Asked Questions

•What is the resistance reading I should expect from a good ice maker motor?

Typically, a good ice maker motor will have a resistance reading between 500 and 1500 ohms, but check the specific motor's documentation if available.

•How do I manually initiate an ice maker cycle without service mode?

You can often manually initiate a cycle by gently turning the ice maker gear until the ice ejector fingers start to move.

•What type of grease should I use to lubricate the ice maker components?

Use a food-grade silicone grease to lubricate any moving parts in the ice maker assembly.
