The short answer
This page covers the freestanding and undercounter installation of a BlueStar refrigerator — the listing is also written as the single word Bluestar. Fitted this way its water supply usually runs to a valve behind the cabinet rather than into a cupboard, which is the first place to look when ice stops, and that reorders the fault list. A refrigerator holds food safely at 40 °F (4 °C) or below.
What you are seeing
- The problem began within days of the cabinet being moved or cleaned behind
- The ice maker produces nothing at all
- Cubes are hollow, small or only partly formed
- Production has slowed steadily over months
- Ice tastes or smells of the cabinet contents
- Cubes fuse into a single block in the bin
- Body: The kind of ice, or its absence, identifies the cause: The problem began within days of the cabinet being moved or cleaned behind. The ice maker produces nothing at all. Cubes are hollow, small or only partly formed. Production has slowed steadily over months. Ice tastes or smells of the cabinet contents. Cubes fuse into a single block in the bin.
Causes, most likely first
- The supply line pinched behind a freestanding cabinet — Why: pushing a heavy freestanding cabinet back against its own water line crushes it, and ice production stops within a day of the cabinet being moved.
- A saddle valve or shut-off behind the cabinet closed — Why: on a freestanding installation the valve is usually directly behind the appliance rather than in a cupboard, so it is both easy to knock and hard to see.
- The ice maker arm or switch left off — Why: a lever knocked while loading the freezer stops production silently, and it costs nothing to check before touching any plumbing.
- A closed or partly closed shut-off valve — Why: the valve is usually in a cabinet nearby or in the basement below, and it gets closed during other plumbing work and never reopened.
- A water filter overdue for replacement — Why: a filter that has clogged restricts the fill, which produces small or hollow cubes first and no ice eventually; production that declined gradually points straight here.
- A frozen fill tube — Why: the tube ices over when the freezer runs colder than intended, and it gives partial cubes and then nothing at all.

Second, A saddle valve or shut-off behind the cabinet closed: on a freestanding installation the valve is usually directly behind the appliance rather than in a cupboard, so it is both easy to knock and hard to see.

Fourth, A closed or partly closed shut-off valve: the valve is usually in a cabinet nearby or in the basement below, and it gets closed during other plumbing work and never reopened. Fifth, A water filter overdue for replacement: a filter that has clogged restricts the fill, which produces small or hollow cubes first and no ice eventually; production that declined gradually points straight here. Sixth, A frozen fill tube: the tube ices over when the freezer runs colder than intended, and it gives partial cubes and then nothing at all.
What to check, in order
- ease the cabinet forward and look at the water line and its valve, because on a freestanding installation that is where the supply lives.
- check the arm or switch is in the on position, since this costs nothing and stops a great many unnecessary visits.
- find and fully open the shut-off valve, which is usually in a nearby cabinet rather than behind the appliance.
- change the water filter if it is overdue, because a clogged filter is the leading cause of production that declined gradually.
- Body: Follow the water from the supply to the mould: First, ease the cabinet forward and look at the water line and its valve, because on a freestanding installation that is where the supply lives. Second, check the arm or switch is in the on position, since this costs nothing and stops a great many unnecessary visits. Third, find and fully open the shut-off valve, which is usually in a nearby cabinet rather than behind the appliance. Fourth, change the water filter if it is overdue, because a clogged filter is the leading cause of production that declined gradually.
Checks you can do yourself
- Pull the cabinet clear of the wall and check the water line is neither pinched nor kinked behind it — Tools: a torch — Time estimate: a few minutes
- Open the freezer and confirm the ice maker arm or switch is in the on position — Tools: torch — Time estimate: a few minutes
- Locate the water shut-off valve serving the cabinet and confirm it is fully open — Tools: torch — Time estimate: a few minutes
- Replace the water filter and run several litres through the dispenser or discard the first few batches of ice — Tools: a replacement filter — Time estimate: half an hour or so
- Empty the ice bin completely, discard the old ice and let the machine make a fresh batch — Tools: none — Time estimate: overnight
- Body: None of this requires the cabinet to be moved: Pull the cabinet clear of the wall and check the water line is neither pinched nor kinked behind it (a torch; a few minutes). Open the freezer and confirm the ice maker arm or switch is in the on position (torch; a few minutes). Locate the water shut-off valve serving the cabinet and confirm it is fully open (torch; a few minutes). Replace the water filter and run several litres through the dispenser or discard the first few batches of ice (a replacement filter; half an hour or so). Empty the ice bin completely, discard the old ice and let the machine make a fresh batch (none; overnight).
Safety first
Safety
A freezer holds food safely at 0 °F (−18 °C) or below. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Never thaw a frozen fill tube with a heat gun or an open flame; the surrounding parts are plastic and the tubing behind the panel carries refrigerant. Discard the first batches of ice after any filter change. unplug-before-service freezer-0f
When to stop and call a technician
These need a technician: The line is undamaged and the valve is open and no ice is produced. No ice at all with the arm on, the valve open and a fresh filter. Cubes stay hollow after the filter has been changed. The fill tube ices over repeatedly after being cleared.

What this page does not cover
This page is generalized across every refrigerator sold under the BlueStar name: it separates neither the freestanding cabinets from the undercounter ones and the stainless fronts from the panel-ready ones, and it names no individual model. Where a family- or model-specific page exists it is linked here and it outranks this one for that machine; at present no page beneath this one narrows to a single family, so treat the ranking above as the brand-level pattern rather than a reading of your serial plate. The same appliances are listed as the single word Bluestar; those pages cover the built-in column installation and the deeper diagnostic tier, and they are linked here. For the other faults that turn up on this machine, start from Common BLUE STAR Refrigerator Problems.
