Admiral Refrigerator Water Filter Bypass Plug for Older... | appliancefaults.com

Technical Background:

Older Admiral refrigerators utilize a water inlet valve controlled by the main control unit (MCU). When the bypass plug is installed, the water filter sensor should register that the filter is bypassed, allowing the MCU to open the water inlet valve when water is requested. Voltage is typically routed to the water inlet valve based on user input at the dispenser. The MCU interprets signals from the dispenser and sensors and provides the necessary voltage (120V AC) to activate the water inlet valve.

Symptoms:

The refrigerator isn't dispensing water or making ice even after installing the bypass plug. Water may be leaking around the filter housing. The refrigerator might be making unusual noises.

Possible Causes:

Incorrect bypass plug system.
Faulty water inlet valve.
Clogged water lines.
Defective water filter head.
Frozen water lines.
Low water pressure.

Solution:

1

Disconnect the refrigerator from the 120V AC power outlet.
2

Verify the bypass plug is fully and correctly installed in the water filter housing. Ensure it is pushed in firmly and seated properly.
3

Check the water inlet valve using a multimeter. Disconnect the wires from the valve and test for continuity. A reading of around 500-1500 ohms is typical. If there is no continuity, replace the water inlet valve.
4

Inspect the water lines for any kinks or blockages. Disconnect the water lines and blow air through them to clear any obstructions.
5

Examine the water filter head for cracks or damage. If the head is damaged, replace it.
6

If water lines are frozen, thaw them with a hair dryer or by leaving the refrigerator unplugged for several hours.
7

Confirm adequate water pressure (minimum 20 PSI) to the refrigerator.

Safety Warning:

Always disconnect the refrigerator from the power source (Lock Out/Tag Out) before performing any repairs. High voltage is present in the appliance. Wear appropriate safety glasses during troubleshooting.

Prevention:

Replace the water filter every 6 months, even if it doesn't appear dirty. This prevents sediment buildup and potential clogging of the water lines and components. Periodically inspect the water lines for kinks or damage.

Expert Tip:

Some older Admiral refrigerators have a test mode. Simultaneously pressing and holding the 'Water' and 'Ice' dispenser pads for 5 seconds may activate a diagnostic cycle, allowing you to manually activate the water valve. Refer to the service manual for specific procedures for the model you are working on.

Frequently Asked Questions

•How do I access the water inlet valve?

The water inlet valve is typically located at the back of the refrigerator, near the bottom. You may need to remove the lower access panel to access it. Unplug the refrigerator before attempting any repairs.

•What is the correct bypass plug for my Admiral refrigerator model?

The correct bypass plug varies depending on the model. Refer to your refrigerator's owner's manual or contact Admiral customer service to identify the correct bypass plug part number for your specific model. Using the wrong bypass plug can cause leaks or prevent the refrigerator from dispensing water.

•How do I check the water pressure going to my refrigerator?

You can use a water pressure gauge to check the pressure at the water supply line connected to the refrigerator. A standard gauge with a hose fitting can be connected to the water line after disconnecting it from the refrigerator. Ensure the water supply is turned on to get an accurate reading. Minimum pressure should be 20 PSI.
