Sub-Zero ice maker repair — freezer compartment opened for service

Sub-Zero Ice Maker Repair · Seattle, Bellevue & Everett, WA
No ice, slow ice, or water where the ice should be? Ace Appliance Service diagnoses and repairs ice makers in built-in Sub-Zero refrigerators and freezers across King and Snohomish County. We find out whether the problem is the ice maker itself, the water supply, or the freezer's cooling — before recommending a repair.
What we fix
The bin stays empty even though the freezer feels cold
Most requestedToo little ice, small or hollow cubes, or cubes frozen together
Water on the freezer floor, or ice building up around the ice maker and bin
Ice stuck in the mold, or an ice maker that stopped moving mid-cycle
Before you book
Some "broken" ice makers are simply switched off or starved of water. These checks are safe for any homeowner and can save you a service call.
Is the ice maker switched on?
On many models the ice maker has its own on/off control. If yours has a wire shut-off arm (like the one in the photo below), make sure it isn't stuck in the raised, "off" position.
Is the water turned on?
Built-in units are fed by a supply line with a shutoff valve, often under the sink or behind the unit's lower grille. After remodels or plumbing work, it's easy to leave it closed.
Is the water filter overdue?
A clogged filter restricts water flow, which often shows up as small or hollow cubes before the ice stops entirely. If your unit has a filter and it hasn't been changed in a long time, start there.
Is the freezer actually cold?
An ice maker only cycles when the freezer is cold enough. If frozen food is softening too, the real problem is cooling — see our Sub-Zero freezer won't cool case study.
Diagnosis
"No ice" on a Sub-Zero can come from several different parts, and each one calls for a different repair. The ice maker needs water delivered through an inlet valve and a fill tube, a cold enough freezer to freeze it, and a working ice maker module to harvest the cubes into the bin.
When any one of those fails, the result at the door looks the same: an empty bin. A water inlet valve that no longer opens, a fill tube that has frozen shut, a failed ice maker module, or a freezer that isn't holding temperature can all be behind it. Replacing the ice maker when the real fault is the water valve — or the cooling system — means paying twice.
That's why we test the water supply, the valve, the ice maker, and the freezer's cooling before recommending a repair. On the 26-year-old Sub-Zero 700BFI in Woodinville, the freezer had stopped cooling from a refrigerant leak. The ice maker came out so the sealed system could be rebuilt with a new genuine compressor and evaporator, then went back in — and the unit has run properly since.
Wondering whether an older Sub-Zero is worth fixing at all? Built-in Sub-Zero refrigeration commonly lasts 20 to 35 years or more — see repair or replace? for how we think about it.

Reviews
"Max was wonderful! He was efficient and knowledgeable. He fixed my leaking Sub-Zero refrigerator, my ice maker that was not dispensing, serviced my refrigerator and also fixed a gas burner that was not working. I will definitely use him again in the future!"
"Amazing job all around! Fixed my fridge and freezer! Great communication and very professional. Highly recommend!"
"Max was responsive, arrived on time, and did a great job replacing the ice maker in our LG fridge. He was professional, accommodating of my tenant's schedules, and made the entire process easy."

Questions
Yes. Ace Appliance Service repairs ice makers in built-in and integrated Sub-Zero refrigerators and freezers — ice makers that have stopped producing ice, are jammed, running slow, or leaking around the bin — using genuine replacement parts.
It depends on what's actually failed — a water valve, a frozen fill tube, the ice maker itself, or the freezer's cooling are very different repairs. We diagnose the cause on-site first and give you a clear price before any repair begins. If you go ahead, the service call fee applies toward the repair.
Yes. High-end repairs are backed by a full year on parts and labor. If something we fixed fails, call us back.
Often, yes. Most calls get scheduled same-day or next-day. If water is leaking onto the floor, turn off the water supply to the unit and tell us when you call.

Start with the simple checks above: the ice maker's on/off control or shut-off arm, the water supply valve, and the water filter. If all three are fine, the usual suspects are a water inlet valve that no longer opens, a fill tube that has frozen shut, or a failed ice maker module. Each needs a different repair, so we test before replacing anything.
That usually points to not enough water reaching the ice maker — a clogged water filter, low water pressure, a partly closed supply valve, or a water valve starting to fail. A freezer running warmer than it should can also slow ice production.
Ice buildup on the ice maker or bin, or water on the freezer floor, often means water is going where it shouldn't — for example a valve that doesn't fully close or a fill tube that isn't draining into the mold properly. Turn off the water supply to the unit to stop further buildup, and have it looked at before it damages the cabinetry around a built-in unit.
Then the ice maker is probably not the problem — the freezer isn't cold enough for it to cycle. That's a cooling repair, like the failed compressor relay in our Everett case study or the sealed system rebuild in our Woodinville case study.
