Parts for Ge GNRQ18NBN: Water Filter Assembly Parts

Replacement pre/post reverse-osmosis (RO) filter cartridge that helps trap sediment and reduce chlorine taste and odor before and after the RO membrane, improving water taste and protecting downstream components. What it does:

• Captures sediment and particulate that can cause cloudy or gritty water
• Reduces chlorine taste and odor that affects water flavor
• Protects the RO membrane and downstream fittings from premature fouling
• Helps restore expected water taste when existing filters are spent

• Turn off the water supply and relieve system pressure before servicing the RO system
• Follow the OEM service manual for correct filter orientation and sealing procedures
• Inspect and replace any worn O-rings or seals to prevent leaks; lubricate with food-grade silicone if recommended
• Dispose of used filter cartridges according to local regulations

This reverse osmosis (RO) membrane filter replaces a worn RO membrane to restore your system's ability to reduce dissolved contaminants and improve tasting water. Designed for use in compatible point-of-use RO housings. What it does:

• Traps and separates dissolved solids and TDS to help improve water clarity and taste
• Helps reduce common RO symptoms like weak water flow, off-taste, or cloudy water when the membrane is failing
• Works as the main semi-permeable element in an RO stage to maintain filtering performance
• Use with pre- and post-filters for optimal RO system operation

• One RO membrane filter

• Replace only with the same membrane type specified for your RO system; follow OEM instructions
• Flush new membrane per system instructions before use to remove preservative and air
• Shut off water and relieve pressure before removing filter housings

This manifold assembly routes and controls gas from the regulator to the cooktop burners, restoring proper fuel distribution for reliable burner operation. Fits the OEM mounting and connection points for direct replacement. What it does:

• Distributes gas evenly from the regulator to individual burner valves for consistent flame
• Replaces a cracked, corroded, or damaged manifold that causes weak or uneven flames
• Addresses ignition or lighting issues when burners won't receive fuel
• Helps stop intermittent gas flow that can cause sputtering or low heat at burners

• One complete manifold assembly as shown

• Turn off the gas supply and electrical power before starting work
• Use proper gas connections and check all fittings for leaks with a soap solution or leak detector

Diaphragm kit replaces a worn flexible diaphragm and seals used in the appliance's valve assembly, restoring proper sealing and valve action to help prevent leaks and intermittent operation. What it does:

• Replaces the flexible diaphragm that forms the internal seal in a valve assembly.
• Restores proper valve sealing to help stop leaks and maintain correct fluid flow.
• Can resolve symptoms like intermittent valve operation, failure to fill, or reduced flow.
• Helps return smooth actuator movement and consistent valve response.

• Disconnect power and shut off any water or gas supplies before beginning service.
• Use basic hand tools and follow the appliance's service diagram for correct valve access.
• Inspect valve housing and mating surfaces; replace the whole kit if any mating surfaces are damaged.

This check valve kit helps prevent backflow and keeps appliance water flow moving in the correct direction to protect internal components and maintain correct water delivery. It's a small replacement kit for the appliance water system. What it does

• Stops reverse flow that can cause contamination or pressure issues in the water line
• Helps maintain steady water flow to ice makers, dispensers, or inlet systems
• Can reduce intermittent filling problems caused by a failed check valve
• Functions as a one-way valve to protect downstream components

• One check valve kit

• Turn off water supply and unplug the appliance before starting work
• Use proper tubing connectors or clamps; replace any damaged hoses

This flow control kit regulates the water flow rate in your water softener during brine draw and rinse cycles. Replacing a clogged or worn flow control helps restore proper regeneration performance and more consistent soft water. What it does:

• Maintains the designed flow rate through the venturi during regeneration
• Supports proper brine draw and rinse for effective resin cleaning
• Helps prevent over/under flow that can reduce softening performance
• Symptoms may include weak or no brine draw, incomplete regeneration, or persistent hard water

• One flow control kit

• Unplug the unit, place the softener in bypass, and shut off the water supply; relieve system pressure by opening a nearby faucet
• Keep the work area clean; note the orientation of each component during removal
• Install the new parts in the same order and seating depth; do not overtighten plastic components
• Return to service and run a manual regeneration; check for leaks and proper operation

This is the dedicated drinking water faucet used with select GE under-sink filtration and reverse osmosis systems. It dispenses filtered water at the sink and provides an integrated air gap to help prevent drain water backflow into the system.

• Directs filtered water from the system to your sink for convenient dispensing
• Built-in air gap helps protect the system from potential drain line backflow
• Common signs of a failing faucet include leaks at the base, drips from the spout, low or inconsistent flow, or a loose/creaking handle
• Replacing a worn faucet can restore proper flow and stop persistent dripping or seeping

• Shut off water supply and depressurize the filtration/RO system before starting
• Place the faucet in an appropriate sink/countertop hole; tighten the mounting hardware securely but do not overtighten
• Connect tubing per color/port labels and route air-gap drain lines with a downward slope to the drain
• Check all connections for leaks, then flush the system per the product instructions
