On Whirlpool side-by-side and French-door models, the dispenser relies on steady supply pressure, an open shutoff, a clean filter, unfrozen reservoir/door line, and a functional inlet valve and paddle switch. If any link is out of spec, flow drops to a trickle or stops completely. After a filter change, trapped air can also cause sputtering or no-flow until purged.
Our diagnostic isolates whether the problem is house supply, filter/regulator, inlet valve, internal reservoir/door line (including freeze-ups), switch/paddle, door switch, or a control/board fault. We test pressure and flow at multiple points, inspect for kinks, ice, and mineral buildup, and verify electrical signals at the valve.
We start at the source and move downstream so no guesswork is left. Pressure is verified at the house shutoff, through the filter head, and at the inlet valve. Electrical tests confirm that pressing the paddle sends correct voltage to the valve and that the door switch/UI logic enables dispensing.
After repair we run a measured-flow test to confirm pressure and delivery, then advise on filter intervals and placement to avoid future kinks or freeze-ups.
If flow drops suddenly after a move or filter swap, check for a kink, fully open the shutoff, and purge air before assuming a component failure.
Likely intermittent switch, harness fatigue in the door hinge, or partial freezing of the door line. We test all three and monitor live voltage during dispense.
Often yes. Clogged or off-brand filters restrict pressure. Install the correct filter and purge 2–3 gallons to restore steady flow.
The valve may energize but not open (mechanical failure) or the reservoir/door line is frozen. We isolate by measuring valve output and checking for flow at upstream points.
