Frigidaire PureSource Ultra II Filter Housing Cracked... | appliancefaults.com

Technical Background:

The MCU (Main Control Unit) manages the water flow and ice production. The filter housing is a passive component, but a crack compromises the sealed water path. Water pressure from the house supply (typically 40-60 PSI) will continuously force water through the crack.

Symptoms:

The homeowner observes water leaking from the filter housing area inside the refrigerator. The leak may be a slow drip or a steady stream, depending on the severity of the crack. Water may also be pooling on the floor in front of the refrigerator.

Possible Causes:

Age and material degradation of the plastic housing.
Excessive water pressure exceeding 120 PSI.
Freezing temperatures causing expansion and cracking.
Overtightening of the filter during system.
Water hammer or pressure surges in the plumbing system.

Solution:

1

Turn off the water supply to the refrigerator. Locate the shut-off valve, usually under the sink or behind the fridge.
2

Unplug the refrigerator from the 120V AC outlet to prevent electrical shock.
3

Carefully remove the water filter from the housing by turning it counterclockwise.
4

Inspect the filter housing for cracks, paying close attention to the seams and connection points.
5

If cracked, purchase a replacement filter housing assembly (part number varies by model).
6

Install the new filter housing, ensuring the O-rings are properly seated.
7

Reinstall the water filter and turn the water supply back on slowly. Check for leaks.

Safety Warning:

Always disconnect power to the refrigerator at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed. Water and electricity are a dangerous combination.

Prevention:

Replace the water filter every six months or as recommended by the manufacturer. Avoid overtightening the filter during system. Consider installing a water pressure regulator to prevent excessive pressure from damaging the filter housing and other components.

Expert Tip:

Apply a small amount of food-grade silicone grease to the filter O-rings before system to ensure a proper seal and prevent future leaks. This also makes filter removal easier.

Frequently Asked Questions

•What is the part number for the replacement filter housing?

The part number for the replacement filter housing varies depending on the specific model of your Frigidaire PureSource Ultra II refrigerator. Check the model number (located on a sticker inside the refrigerator) and search for the correct part number online or at a local appliance parts store.

•How do I check the water pressure in my home?

You can purchase a water pressure gauge at most hardware stores. Attach the gauge to an outdoor faucet or washing machine connection and read the pressure. Ideal water pressure is between 40 and 60 PSI. If it's consistently above 80 PSI, consider installing a pressure regulator.

•What type of food-grade silicone grease should I use?

Use a food-grade silicone grease specifically designed for potable water systems. This type of grease is non-toxic and won't contaminate the water supply. Look for products labeled as NSF-61 certified.
