Whirlpool GSF26C5EXB02 . ice maker doesnt make ice
On the Whirlpool GSF26C5EXB02, I would diagnose this before replacing the ice maker. This model uses an in-door ice maker ( Whirlpool WPW10251076 Refrigerator Icemaker Assembly | Genuine OEM Part ) , and one failure point worth checking early is the wiring at the bottom freezer-door hinge.
Start with these checks
1. Check freezer temperature first.
You want roughly 0°F, preferably no warmer than about 5°F. If the freezer is running 10–15°F or warmer, the ice maker may not cycle even though everything else seems normal. Whirlpool also lists freezer temperature/water supply as basic no-ice checks.
2. Look inside the ice maker mold.
This immediately splits the diagnosis:
- Mold is empty: concentrate on water supply, fill tube, inlet valve, wiring, or the ice maker not initiating a fill.
- Mold has frozen cubes sitting in it: water supply is probably doing its job. Concentrate on the ice maker motor/module, temperature sensing, power, or wiring.
3. Check the freezer-door hinge wiring.
Open the freezer door and inspect the wire harness coming through the bottom hinge area. Flex the individual wires gently and look especially closely for a wire that has broken internally or separated.
This family of Whirlpool in-door ice makers has a known real-world failure pattern where repeated door movement damages wiring near the lower hinge.
Quick water test
If the mold is empty, pour approximately 4 ounces of water into the ice maker mold manually.
Wait for it to freeze.
If the ice maker later harvests/dumps those cubes, the ice maker can cycle and I’d move toward the water-fill circuit:
water supply → filter → inlet valve → fill tube → wiring/control signal
The water dispenser working does not prove the ice-maker side of the valve is good because the valve has separate functions/solenoids. The listed water valve for this model is ( Whirlpool WPW10258562 Refrigerator Water Inlet Valve | Genuine OEM Part )
If the manually added water freezes but just sits there and never harvests, don’t replace the water valve. Check the ice maker’s power and especially that freezer-door hinge harness before condemning the ice maker.
What I’d check first
For this particular model, my order would be:
Freezer temperature → ice in mold or empty → bottom freezer-door hinge wiring → manual water test → inlet valve/fill tube → ice maker.
