What it
usually means.

The fill tube is the last few inches of the water path, where it passes through the cold wall of the freezer and pours into the mold. It is built to empty between fills, so nothing is left to freeze. When a few drops are left behind, they freeze, and the next fill adds another layer until the tube closes. A valve that drips after it shuts is the most common reason; low water pressure, which makes the fill trickle rather than rush, is the second. Some models warm the tube with a small heater, and a failed heater lets it ice over. Thawing the tube brings ice back for a while, but it freezes again unless the cause is fixed.

Answer these first

01

Can you see a plug of ice or icicles where the tube enters the mold?
02

Has the tube frozen before, and how long did it stay clear after it was thawed?
03

Is the freezer set colder than usual, or is the door opened very often?
04

Does the ice maker make small cubes on the days before it stops?
05

Does the mold drip or collect water between fills?

Ice maker fill tube frozen: 5 checks, and none of them costs anything.

01

Switch the ice maker off before you touch the tube, so it does not try to fill or harvest while you work.

02

Thaw the plug with a cloth soaked in warm water held against the tube; skip heat guns and hair dryers inside the freezer.

03

Dry the fill cup and the area around the mold before switching the ice maker back on.

Also worth checking

  • Change the water filter if it is due and check the supply valve is fully open, so the fill arrives at full pressure.
  • Note the date you thawed it; if it freezes again within a week or two, book a visit.

How soon does it need a visit?

A frozen fill tube is not urgent, but it tends to come back. Switch the ice maker off, thaw the tube with warm water on a cloth and book a visit if it refreezes, because a dripping valve can also start to leak.

The causes,

5 things ice maker fill tube frozen turns out to be, from valve dripping after it closes to low water pressure.

The cost guide
  1. 01 low to moderate

    Valve dripping after it closes

    A worn valve seat lets a few drops follow the fill down the tube. Each drop freezes, and the tube closes over days.

    Fixed by ice maker water inlet valve repair
  2. 02 low

    Fill tube heater failed

    Some models keep the tube just above freezing with a thin heater. When it fails, the tube ices over even with a good valve.

  3. 03 low

    Tube or its grommet out of place

    A tube pushed out of line, or a grommet that lets cold air in around it, freezes near the wall of the freezer.

    Fixed by frozen fill tube repair
  4. 04 moderate

    Door ice compartment running too cold at the tube

    On a door ice maker, cold air from the duct can blow onto the fill point when the duct or its damper is out of position.

  5. 05 varies

    Low water pressure

    A weak supply, a clogged filter or a partly closed valve makes the fill trickle and cling to the tube instead of rushing through it.

Questions about
ice maker fill tube frozen.

How long does the tube stay clear after thawing?
With the cause still there, anywhere from a few days to a few weeks. If it freezes on a regular cycle, the valve or the water pressure is almost always the reason.
Can I blow hot air at the tube to thaw it?
We advise against it. It puts a mains appliance next to melting water and can warp plastic parts. A warm, wet cloth or a baster of warm water works without the risk.
Why did the tube freeze right after a power outage?
When the power returns, the ice maker can start a fill while the freezer is still recovering, and a slow fill can freeze in the tube. A single thaw usually settles it.
Does setting the freezer warmer stop the tube freezing?
It can slow it but rarely stops it, and it softens the rest of the freezer. Fixing the drip or the pressure is the real answer.
