Frigidaire Refrigerator Water Dispenser Tastes Like... | appliancefaults.com

Technical Background:

The refrigerator's water dispenser system relies on a series of components, including the water inlet valve, water filter, water lines (often copper or polyethylene), internal reservoir, and the dispenser valve. The MCU (Main Control Unit) controls the dispenser valve, sending 120V AC to activate the valve when the dispenser paddle is pressed.

Symptoms:

The homeowner reports that the water dispensed from their Frigidaire refrigerator tastes like copper or metal. This taste is undesirable and suggests a potential contamination issue within the water supply system of the refrigerator.

Possible Causes:

Copper water lines leaching into the water supply.
Internal reservoir contamination.
Dispenser valve corrosion.
Water filter issues.

Solution:

1

Turn off the refrigerator's water supply valve. This is usually located under the sink or behind the refrigerator.
2

Replace the water filter with a new, genuine Frigidaire filter. Follow the manufacturer's instructions.
3

Flush the water dispenser. Dispense approximately 2-3 gallons of water to clear any stagnant water and debris from the lines.
4

Check the water lines. Inspect the copper water line for any signs of corrosion or damage. If the line is old or corroded, replace it with a new, NSF-certified polyethylene water line.
5

If the taste persists, suspect the internal reservoir. Try sanitizing the reservoir by adding 1/4 cup of baking soda to a gallon of water and flushing it through the dispenser. Repeat several times.
6

If sanitizing doesn't resolve the issue, and you suspect the dispenser valve, test the valve's voltage with a multimeter. With the dispenser activated, you should read approximately 120V AC. If the voltage is present but the valve isn't functioning correctly, replace the dispenser valve.

Safety Warning:

Disconnect the refrigerator from the breaker panel before performing any repairs. High voltage is present in the dispenser circuit. Always use appropriate safety precautions and wear safety glasses.

Prevention:

Replace the refrigerator's water filter every six months. Periodically flush the water dispenser, especially if the refrigerator is not used frequently. Use NSF-certified water lines to prevent contamination.

Expert Tip:

Some Frigidaire models have a service mode. To access, simultaneously press and hold the 'Ice On/Off' and 'Lock' buttons for 3 seconds. This may allow you to manually cycle the dispenser valve for diagnostic purposes.

Frequently Asked Questions

•How often should I change the water filter in my Frigidaire refrigerator?

The water filter should be replaced every six months, or sooner if you notice a decrease in water flow or a change in taste or odor.

•What type of water line is recommended for connecting my refrigerator to the water supply?

An NSF-certified polyethylene water line is recommended. Avoid using copper water lines, especially in areas with acidic water, as they can corrode and leach into the water supply.

•How do I sanitize the internal water reservoir in my Frigidaire refrigerator?

Mix 1/4 cup of baking soda with one gallon of water. Pour the solution into the water reservoir (if accessible), or run it through the water dispenser until the reservoir is full. Let it sit for 30 minutes, then flush the reservoir thoroughly by dispensing several gallons of water.
