Refrigerator Water Dispenser Slow or Not Working — Fixes
A water dispenser that trickles or quits is one of the most common fridge complaints — and the fixes go from free to cheap. Work through them in this order, easiest and most likely first.
Most Likely: A Clogged Water Filter
A filter past its six-month life is the number-one cause of weak or no dispenser flow. The quickest test: pull the filter out and try dispensing in bypass (or with the filter removed) — if flow returns to normal, the filter was the problem. Install the correct fresh filter for your brand and flush 2-4 gallons. Don't run permanently without a filter; just use it to confirm the cause.
Frozen Water Line in the Door
If a new filter doesn't help, the supply tube in the freezer-side or door is likely frozen — common when the freezer is set too cold (below about 0 F / -18 C) or the door has been ajar. Symptoms: dispenser hums or clicks but no water, or a very slow trickle. Fix: raise the freezer temp a couple degrees and let the line thaw (a hair dryer on low aimed at the dispenser tube speeds it up). A kinked supply line behind the fridge causes the same thing.
Water Supply, Valve, and Switch
Check the saddle/shutoff valve behind or under the fridge — make sure it is fully open and the line isn't kinked. Low home water pressure (under ~20 psi) also weakens the dispenser. If water flows to the fridge but nothing comes out, the inlet water valve (an electrically controlled valve at the back) or the dispenser switch/actuator may have failed — those are inexpensive parts but a slightly more involved repair. If the same valve also feeds the ice maker, a no-water-anywhere symptom points there.

FAQ
A clogged water filter is the most common cause. Test by removing the filter and dispensing — if flow returns, replace the filter. If not, suspect a frozen door line or low water pressure.
Check the filter first, then look for a frozen supply line in the door (raise freezer temp and let it thaw) and confirm the shutoff valve behind the fridge is fully open. A failed inlet valve or dispenser switch is the next suspect.
Yes — it's very common. If the freezer runs too cold or the door was left open, the thin supply tube freezes. Raising the freezer temperature a couple of degrees and thawing the line usually restores flow.
