Our work

Our Sub-Zero repairs

Our Sub-Zero ice maker repairs include units that stopped producing ice or cycling (a repaired water feed and ice-making mechanism), ice accumulating in the unit (repaired defrost operation) and an undercounter ice maker that stopped cycling (a new timer). We also repair other Sub-Zero appliances, such as refrigerators with changing temperatures and wine storage that stayed warm.

    Our built-in Sub-Zero refrigerator started warming up just before we had family staying with us. The technician treated the unit carefully, isolated the issue, and laid out the options clearly. The repair was handled without damaging the surrounding cabinetry, which was a major concern. Everything is holding temperature again.

    Needed to get my Sub-Zero freezer fixed. Scheduled an appointment online for later this week. Had a manager call me to reschedule for earlier as a time slot opened up. Great service! Freezer is now back working!

    Our Sub-Zero wine cooler was running but not keeping the bottles at the selected temperature. The technician understood the built-in setup, protected the cabinetry, and diagnosed the airflow issue. After the repair, he monitored the temperature drop and explained what to watch over the next day.

    Our Sub-Zero refrigerator in Miami Beach was warm on one side. Communication was excellent, the visit was careful and unhurried, and the refrigerator has maintained the correct temperature ever since.

Sub-Zero ice maker repair for separate and in-freezer units

We repair separate undercounter ice machines, outdoor-rated units and ice makers inside Sub-Zero freezers. When ice production stops or water leaks, we check the water feed, drainage and ice-making mechanism fitted to your unit.

Built-in refrigeration fitted into kitchen cabinetry
  • Sub-Zero Designer undercounter ice makers

    We repair Designer undercounter ice makers with stopped production and leaks, checking whether your machine uses a drain pump or gravity drainage.

  • Sub-Zero UC undercounter ice makers

    We repair UC undercounter ice machines, including outdoor-rated versions, with low production, recurring shutdowns and leaks.

  • Sub-Zero Classic in-freezer ice makers

Common problems

Sub-Zero ice maker problems: causes and repair

Common Sub-Zero ice maker problems include no ice, a frozen fill tube, leaks or a solid ice block, clicking or grinding, ice that will not drop, an undercounter machine that shuts itself off and a bin that overflows. In-freezer ice makers need the freezer at or below 5°F and make about eight cubes every 2–3 hours, while separate undercounter machines run their own cycle and normally drip inside. Luxury Appliances Service checks the water feed, ice-making mechanism and drainage and gives you the repair price before any work.

Sub-Zero ice maker not making ice

A Sub-Zero in-freezer ice maker that is not making ice may still be starting up, or it can have a water-feed, jam or freezer-temperature problem.

Possible causes: A jammed ice cube; low water pressure; a frozen fill tube; a warm freezer; the water valve energized longer than 15 seconds.

Check first: On 600 Series units, confirm the freezer is at or below 5°F; 0°F is recommended. Allow 24 hours after switching on a new unit. In-unit ice makers average eight cubes every 2–3 hours, and the bin may take 1–2 days to fill.

When to call: Production stays low or stops. We check the ongoing loss of production and repair the identified fault.

Sub-Zero ice maker fill tube frozen

A frozen fill tube stops water reaching the ice mold and can come from the water supply or from how the ice maker is switched off.

Possible causes: Water pressure fluctuations; removing the bin or shutting off the water without turning the ice maker off; jammed cubes.

Check first: Turn the ice maker off before you shut off its water supply or remove the bin.

When to call: The tube freezes again. We inspect the water supply and inlet components to find why.

Sub-Zero ice maker leaking or forming a solid ice block

A solid ice block or leak at an in-freezer Sub-Zero ice maker points to the water feed or a jam; undercounter machines behave differently.

Possible causes: A jammed cube; a water valve not operating properly; an incorrect water fill setting.

Check first: In a separate undercounter machine, water spraying inside the assembly and ice melting in the bin can be normal.

When to call: Ice blocks keep forming, or water escapes onto the floor. Our technician checks the water feed and ice maker for the installed series.

Sub-Zero ice maker making clicking or grinding noises

Clicking or grinding from a Sub-Zero ice maker can be normal operation or a sign that a cube or the water feed is holding it up.

Possible causes: Normal operating sounds; a jammed cube blocking the ejector; a lack of water through the valve.

Check first: Note whether ice production has stopped as well.

When to call: The sound continues with a production problem. We locate the noise and check the mechanism and water feed.

Sub-Zero ice maker not dropping ice or making clumps

In-freezer ice that will not drop points to a stuck cube or the mold heater, while clumps of old, unused ice can be normal.

Possible causes: A stuck cube; an ice maker mold heater failure; unused ice fusing over a few days as the freezer goes through defrost cycles.

Check first: Tell old fused ice apart from fresh cubes that will not release; a single clump of old ice is not a repair.

When to call: Fresh cubes repeatedly jam or will not release. Our technician checks the ejector and mold heating.

Sub-Zero ice maker shutting itself off

A UC-15I undercounter ice maker can shut itself off on purpose when it cannot finish making and releasing ice within its normal cycle.

Possible causes: The automatic shut-off mode, which can start after two freeze-and-harvest cycles in a row that each run the full 55 minutes.

When to call: It repeatedly stops. We check why the cycle is taking too long and quote the repair needed to restore production.

Sub-Zero ice maker bin overflowing

An undercounter Sub-Zero ice maker that overfills its bin points to the part that senses when the bin is full.

Possible causes: A failed bin thermostat; a bin thermostat that needs adjustment; a missing bin thermostat clip.

When to call: Fresh ice repeatedly overfills the bin. We inspect the bin-level control and thermostat attachment and quote the repair.

Error codes

Sub-Zero ice maker error codes and display messages

Sub-Zero ice maker codes depend on the series: Classic units use three-part codes with an 8 in the middle, such as 40 8 40 for excessive running or 15 8 00 for an open relay circuit; 600 and 700 Series units show EC30 or Service Ice when the water valve ran too long and the ice maker switched off; Designer Undercounter (DEU) machines show 95-D-01 for a high drain-pump float. Write down the full message and do not open electrical panels or work on the sealed system. We check the water feed, drainage and ice-making controls, then quote the repair. The meanings below follow Sub-Zero’s use-and-care information, checked in October 2026.

Call (786) 808-7771
What does 95-D-01 mean on a Sub-Zero Designer Undercounter (DEU) ice maker?
The drain-pump emergency float is high. Arrange service for the drainage and float system; we check the pump arrangement for your DEU1550I(P).
What does 40 8 01 mean on a Sub-Zero Classic (CL) ice maker?

Repair or replace

Is your Sub-Zero ice maker worth repairing?

Repair usually makes sense when the rest of the appliance is sound: a stopped ice maker may need a water-feed, bin-control or ice-making repair rather than a new refrigerator or machine. A common rule of thumb is to replace an appliance when the repair would cost more than half the price of a new one; for an undercounter machine fitted into your cabinetry, compare with a new unit plus installation. We give you the repair price before any work, so you decide with the number in hand.

Call (786) 808-7771

Can a Sub-Zero ice maker be repaired without replacing the refrigerator?

Yes. An in-freezer ice maker has its own water feed and ice-making mechanism, including the sensing arm and fill tube. We check the ice-making fault and explain which repair is needed before you decide.

How much is a Sub-Zero ice maker diagnostic?

The diagnostic is $145 per appliance, credited toward the repair. You pay it on its own only if you decide not to repair. We give you the repair price before any work, whether the affected appliance is a separate machine or your refrigerator.

How often should a Sub-Zero undercounter ice maker be cleaned?

Every six months: Sub-Zero recommends cleaning and sanitizing the surfaces in contact with the water system at that interval. Recurring shutdowns, overfilling or a leak need a fault check as well as routine care; we check the operating problem and quote any repair needed.

FAQ

Sub-Zero ice maker repair questions

Call (786) 808-7771
Do you repair Sub-Zero undercounter ice machines as well as in-freezer ice makers?
Yes. We repair ice makers inside Sub-Zero freezers, separate undercounter machines and outdoor-rated models, and check the water supply, drainage and ice-making mechanism for your unit.
How long does a new Sub-Zero ice maker take to make ice?
About 24 hours for the first ice after you switch on a new unit and its ice maker. In-unit ice makers average eight cubes every 2–3 hours, so a bin may take 1–2 days to fill. If production stops during normal use, arrange service.
Can the water fill be adjusted on every Sub-Zero ice maker?
No. Classic BI and Designer IT/IC ice makers have no water-fill adjustment. We check the inlet and ice-making mechanism for your installed series and quote the repair needed.
Is it normal for water to drip inside a Sub-Zero undercounter ice maker?
Yes. Spraying and dripping inside the ice-making assembly, and ice melting in the bin, are normal operation. Water leaving the appliance or repeated shutdowns call for a drainage and water-feed check.
