GC5THGXKT00 specifics — where the filter actually lives
Finding the bay is the easy part — this chassis puts it in the fresh-food compartment, placement dependent on the dispenser package, so expect to clear one shelf edge before you have working room. This is a twist-style bay, the friendlier design: one twist to release, one to lock; between them you are holding the entire service procedure.
Two quirks worth knowing before you order: keep a folded towel under the bay before you open it; the line holds a cup of water even with the valve shut. The constant across every trim of this machine is the cartridge line — the GC5THGXKT00 shares its water path with the whole EDR5RXD1 generation — the cartridge is the common denominator, not the door count. Revision 00 changed trim details, not the water circuit; order with confidence by model stem.
Reading the GC5THGXKT00 model code — what the digits tell you
Catalog convention puts the GC5THGXKT00 near 2001 to 2005 — an approximation, useful for bracketing the cartridge era only. The trim walk never reaches the plumbing: fit charts key on the EDR5RXD1 cartridge family rather than the door configuration, so trim differences never change the order.
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.

GC5THGXKT00 filter questions
Filter light reset on the Whirlpool GC5THGXKT00 — how?
Press and hold the reset control until the light clears (a few seconds), with the new cartridge already seated — the GC5THGXKT00 owner’s manual lists the button location for your control panel.
Whirlpool GC5THGXKT00: bypass plug needed without a filter?
Nothing to buy — the EDR5RXD1 housing closes without a cartridge; water runs unfiltered until the next one goes in.
Are off-brand filters safe for a Whirlpool 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 EDR5RXD1 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 GC5THGXKT00?
Every six months or at the rated gallon capacity, whichever comes first — the EDR5RXD1 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.
