Sub-Zero built-in refrigerators (600, 700, Designer, Pro 48) and under-counter ice makers (UC-15I, UC-15IP) use a different ice maker family than mass-market brands — a dedicated icemaker module with a separate condenser, water filter, and (on some units) a pump-driven dispenser. Factory-trained technicians, OEM parts, EPA 608 certified for any sealed-system work. Part of our full Sub-Zero appliance repair coverage and our Twin Cities ice maker repair service.

Quick answer
Most Sub-Zero ice maker repairs land $345–$725 all-in. The flat $149 trip fee on Sub-Zero / built-in jobs is waived when you approve the repair. Sub-Zero ice makers are built to be serviced for decades — even a 20-year-old 632 or 685 is almost always worth repairing because the unit is part of a $12K+ refrigerator that's still going strong. We do not substitute aftermarket parts on Sub-Zero work, ever.
Sub-Zero ice maker failures
Most common cause: Failed water inlet valve, scaled-up water filter, frozen fill tube, failed icemaker module, or — on older 500 / 600 series — a failing condenser fan that's letting the icemaker compartment run warm.
What we do: Replace water filter, swap OEM inlet valve, thaw fill tube, replace icemaker module if motor or thermistor failed. Condenser cleaning and fan replacement as needed.
$345–$525 all-in
Most common cause: Cracked fill tube, failed inlet valve, cracked icemaker mold, or — on built-ins — a clogged drain tube in the icemaker compartment routing water into the cabinet.
What we do: Replace fill tube + inlet valve, clear drain tube, dry insulation pocket before reinstall. On 600/700 series we also check the secondary drain on the freezer.
$385–$585 all-in
Most common cause: These vintage built-ins (1996–2010) had a known failure mode: the icemaker fill tube freezes from a partial drain blockage, and the icemaker module shuts off. The fix is a full drain inspection + fill tube + module if the module thermistor has drifted.
What we do: Full drain clear, fill tube replacement, module swap if thermistor fails forced-harvest test. We bring service-bulletin updated parts.
$425–$625 all-in
Most common cause: Failed condenser fan, scaled-up evaporator, failed inlet valve, or a failing pump (on UC-15IP pump-equipped units). These units are tucked into cabinetry and run hot if the condenser intake is restricted.
What we do: Pull the unit, clean condenser, replace fan and pump as needed, descale evaporator. Confirm cabinetry airflow meets Sub-Zero spec before reinstall.
$485–$725 all-in
Most common cause: Exhausted water filter (Sub-Zero specifies filter change every 9–12 months), or biofilm in the fill tube and icemaker mold.
What we do: Replace OEM Sub-Zero water filter, deep-clean fill tube + mold with Sub-Zero approved cleaner. Re-test water quality before sign-off.

FAQs
Yes — our techs are factory-trained on the full Sub-Zero line (500, 600, 700, Designer, Pro 48, UC under-counter, BI built-ins) and EPA Section 608 certified for any sealed-system or refrigerant work. We use OEM Sub-Zero parts only and never substitute aftermarket on warranty repairs.
Most Sub-Zero ice maker repairs land $345–$725 all-in (parts + labor + the $149 built-in trip fee, credited to the repair). Sub-Zero parts cost more than mass-market brands but the units are designed for decades of service — even a 20-year-old built-in is almost always worth repairing.
Almost always yes. A Sub-Zero 600-series built-in cost $9K–$14K new and replacement runs $12K–$18K plus cabinetry rework. A $500 ice maker repair on a still-cooling Sub-Zero is excellent value. The exceptions are sealed-system failures (compressor, evaporator) on units past year 20 — we tell you straight when replacement makes sense.
Sub-Zero specifies the water filter every 9–12 months. In hard-water cities (Plymouth, Eden Prairie, Minnetonka, Wayzata) we recommend the 9-month interval. Skipping filter changes is the #1 cause of premature icemaker failure on Sub-Zero.
Yes — UC-15I (gravity-drain) and UC-15IP (pump-equipped) under-counter units are a regular call. We carry OEM condenser fans, pumps, inlet valves, and modules on the truck.
Yes — Sub-Zero, Wolf, and Cove are all factory-trained service for us. Cove dishwashers and Wolf cooking products are routine work; the Sub-Zero side is where the ice maker work lives.
Yes — every Sub-Zero ice maker repair includes a 1-year written parts-and-labor warranty, in addition to any remaining Sub-Zero factory warranty (12 years sealed-system, 2 years full coverage on new units).
Same-day windows on weekdays when you call before 2pm. We dispatch dedicated built-in / Sub-Zero techs (not generalist routes) so scheduling sometimes runs 1 business day for the right tech to be on your route.
