PSD243LGRQ specifics — where the filter actually lives
The filter bay on the PSD243LGRQ inside the fresh-food cavity, position varying with dispenser spec, a deliberate placement that keeps the swap away from the door seals and drawer rails. Mechanically the PSD243LGRQ uses a twist-in cartridge: the ears on the cartridge neck are the guide — line them up, lift into the seat, and quarter-turn home.
The small print owners learn the hard way: keep a folded towel under the bay before you open it; the line holds a cup of water even with the valve shut. Under the cabinet differences one thing holds: the EDR4RXD1 cartridge family is what every fit listing for this chassis resolves to, OEM and certified alternative alike. That RQ suffix is trim-level shorthand. Maytag kept the EDR4RXD1 bay common to every finish in the line.
Reading the PSD243LGRQ model code — what the digits tell you
The PSD243LGRQ code suggests roughly 2017-2021 production — approximately right, which is all a parts search needs. The stable part of the PSD243LGRQ story is the water path: the same EDR4RXD1 family covers this chassis end to end.
Swap it in 5 minutes
- Twist the old cartridge a quarter turn counterclockwise and pull it straight down — keep a towel in reach for the dribble.
- Fill the new cartridge with cold tap water so the chamber is not fighting an air pocket.
- Offer the new cartridge to the bay, push up, and twist a quarter turn clockwise until the stop catches.
- Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.

PSD243LGRQ filter questions
PSD243LGRQ filter light will not turn off — what is the reset step?
Seat the new cartridge first, then hold the filter-reset control for a few seconds until the status light clears — the exact button placement varies by control panel, so check the PSD243LGRQ owner’s manual page for filter status.
Does the Maytag PSD243LGRQ need a bypass plug when the filter is out?
No — the EDR4RXD1 bay seals on the cartridge itself, so removing it just means unfiltered water until the next change, not a leak.
Are off-brand filters safe for a Maytag refrigerator?
Certified aftermarket cartridges are built to the same NSF test standards as the OEM part, and federal warranty law (Magnuson-Moss) protects your coverage when you use them.
Why is the OEM EDR4RXD1 cartridge so much more expensive?
Part of the OEM price is the badge and the distribution chain. Certified alternatives meet the same test standards at a lower unit price, especially in multi-packs.
How often should I replace the filter in my PSD243LGRQ?
Every six months or at the rated gallon capacity, whichever comes first — the EDR4RXD1 class cartridges all share that service interval.
Do I need to turn off the water supply to change it?
No — the bay is designed for a live swap. Expect a small dribble, keep a towel in reach, and flush a couple of gallons through the new cartridge before the first glass.
