If you’re noticing water leaking around the filter area in your Frigidaire refrigerator, a worn or damaged O-ring might be the cause. This small rubber gasket, part number 218904301, sits inside the water filter housing and helps create a watertight seal. Over time, it can dry out, crack, or lose its shape, leading to drips or pressure issues. The good news is that replacing the O-ring is quick, inexpensive, and totally doable on your own. In this guide, we’ll show you how to swap in a new one and stop those pesky leaks for good. Let’s get started.

What is the water filter housing o-ring?

The filter housing is where the water filter cartridge sits inside the refrigerator compartment. It connects to the water supply line at the top and has a dispenser actuator lever at the bottom.

The bottom of the housing cover attaches securely to the filter base using a threaded ring. An O-ring seals this connection to prevent water from leaking out.

Over time, opening and closing the housing to change filters can cause the o-ring to compress and crack. A damaged o-ring then leaks, dripping down into the refrigerator compartment.

Symptoms of a faulty water filter housing o-ring

• The main symptom is finding a puddle of water on the floor at the base of the refrigerator. Dripping from a cracked filter housing gasket eventually overflows the crisper bins.
• Inspect under the produce bins for standing water or damp areas on the refrigerator floor. Leaking from overhead can directly wet shelving and contents.
• Discolored trails of minerals left behind from continuous dripping indicate an ongoing leak issue.
• Excess moisture from leaks promotes microbial growth like mold in confined refrigerator spaces unseen. An unusual musty odor emanates as a result.

When you encounter any of these scenarios, examine the filter housing o-ring first. As the only major water line directly above cold food storage, it’s the most likely source of drips and leaks.

Safety first

When working on any appliance, always keep safety first to avoid personal injury or damage to the appliance or parts. Here are some safety 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 preventing 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 clearly 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.
• 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.
• Turn off the water supply at the outlet before beginning repairs. Keep towels ready to catch any residual water in the system when removing parts.
