Most "no ice" calls are water delivery, not the freezer
When a Sub-Zero ice maker quits, the freezer is usually fine — the problem is getting water to the mold and harvesting cubes from it. A failing fill valve, a frozen fill tube, a clogged line or a tired module each stops production. Clear-ice makers add a few extra parts (a recirculation pump and a cutter grid) that we also check.
In San Mateo we see a lot of slow or small cubes traced to old saddle valves and neglected water filters, plus the occasional under-island leak. We confirm the water path end to end before replacing the module.
Ice maker and water-line symptoms
| Symptom | Likely cause | What we do first |
|---|---|---|
| No ice at all | Fill valve, frozen fill tube or no water supply | Test the valve, thaw the tube, confirm supply and pressure |
| Small or slow cubes | Low water flow, clogged filter or partial valve | Replace the filter, clear the line, verify flow |
| Cloudy or off-taste ice | Old filter or stale water in the line | Replace the OEM filter and flush the system |
| Water leaking near the unit | Cracked line, loose fitting or valve seep | Find the leak point and replace the fitting or line |
| Ice maker runs but bin stays empty | Module, ejector or harvest fault | Test the module and ejector; replace the failed part |
What to check before you call
Quick checks that help us arrive with the right ice-maker parts in San Mateo.
- Confirm the ice maker is switched on. A bumped power switch or raised shutoff arm is the most common "no ice" cause. Make sure it is on.
- Check the water filter age. A filter past its life slows flow and clouds the cubes. Note when it was last changed.
- Look for a leak. Check under and behind the unit for water — a wet spot points to the line or a fitting.
- Listen for a fill cycle. Note whether you hear water filling. No fill points to the valve or tube; fill with no ice points to the module.
- Call with the details. Call (650) 484-4687 or book online with your model number and what you observed.
Leave these to a technician
- Do not pour hot water into the mold to "fix" it — it can crack components.
- Do not over-tighten a leaking compression fitting; it can split the line.
- Do not ignore a slow drip behind an island — water travels and damages cabinetry.

San Mateo ice-maker reviews
-
The ice maker stopped and water pooled under the drawers. It turned out to be a frozen fill tube and a clogged drain, not the whole module. Fixed the same day with OEM parts, clear pricing and no upsell. Highly recommend for San Mateo built-ins.

GE Monogram built-in with a leaking water line and no ice. They located the cracked fitting, replaced it before it damaged the floor, and restored the ice maker with OEM parts. Prompt, clean, and the $89 was waived with the repair.

Cloudy, slow ice on our clear-ice maker. They changed the OEM filter, flushed the line, and checked the recirculation pump. We had clear cubes again the same day. Simple, honest, no drama.

Frequently asked questions
Why has my Sub-Zero ice maker stopped making ice?
Most often it is water delivery rather than the freezer: a failed fill valve, a frozen fill tube or a shutoff arm that got bumped. Less often it is the module or ejector. We confirm whether water is actually reaching the mold, and on clear-ice models check the recirculation pump, before replacing any part.
How much does Sub-Zero ice maker repair cost in San Mateo?
Visits start with an $89 service call that is waived when you book the repair. Ice maker and water-line work typically falls in a draft range of $275–$850 depending on whether it is a fill valve, fill tube, filter or module. You approve a firm quote after diagnosis, and the labor is covered for 365 days.
My clear ice is coming out cloudy — what is wrong?
Cloudy cubes usually mean an old water filter or stale water sitting in the line, not a failing machine. A fresh genuine OEM filter and a full system flush almost always restore clear ice. If they do not, we check the recirculation pump and cutter grid on clear-ice models to find what is interrupting the freeze cycle.
Can you fix a leaking water line under my island?
Yes. We locate the exact leak point — a cracked supply line, a loose compression fitting or a seeping fill valve — and replace the failed part before it damages cabinetry or flooring. A slow drip behind an island can travel a long way, so it is worth booking promptly rather than waiting it out.
Do you service standalone clear-ice makers as well as fridge ice makers?
Yes. We service built-in ice modules inside refrigerators and dedicated clear-ice machines tucked into islands, both of which come down to the same chain: water delivery, the module and the harvest system. Clear-ice units simply add a recirculation pump and cutter grid that we also test as part of the diagnosis.
How long does an ice maker repair take?
Most ice maker and water-line jobs run one to three hours on site. Because we carry common fill valves, modules and filters on the truck, many San Mateo calls finish in a single visit rather than waiting on a part order — and you will have clear ice again the same day instead of days later.
My Sub-Zero ice maker stopped after a power flicker — what now?
A brief outage can leave the ice maker paused or in an error state and sometimes trips its shutoff arm, so start with a clean restart: switch the ice maker off, wait a minute, switch it back on, and confirm the arm is down and the unit has water. If it still will not produce after a full cycle, a surge can also knock out the control or the inlet valve, which we test and repair. If you see water where ice should be, see our water leak & drain page.
