Sub-Zero ice maker not making ice?
Factory-trained — most techs won't touch them.
UC-15, UC-24 and ID series — undercounter built-ins with a sealed R134a refrigeration circuit. We carry the vacuum pump and manifold gauge set, quote a fixed price up front, and diagnose same-day. If we don't fix it, you don't pay.
Same-day service
Why your Sub-Zero stopped making ice
Sealed R134a circuit, built-in cabinet — typical failure points.
Mineral buildup / scale
Hard-water scale on the heat exchanger. Professional Sub-Zero descaling procedure. Labor: $200–$500.
Drain pump failure
Water standing in the drip tray, cloudy or slow ice. Pump swap in 30–40 min. Labor: $400–$800.
R134a compressor
Replacement with full evacuation and recharge. Cost: $800–$1,800.
Thermostat / sensor
Ice too thin or the harvest cycle not triggering. Labor: $200–$500.
Control board
Won't start, erratic cycles. OEM board only. Cost: $400–$900.

Certified Sub-Zero technician · Orange
Sub-Zero ice makers are dedicated refrigeration systems with an R134a compressor and precision thermostat, mounted inside cabinetry where panel fit, water supply, and drain routing matter as much as the machine itself. Most appliance techs won't work on them.
I completed Sub-Zero factory training. Vacuum pump and manifold gauge set in the van, all parts ordered through the authorized distributor. Leaks on a Sub-Zero are especially urgent — water can reach toe kicks, flooring, or custom panels before you ever see a puddle.
A new Sub-Zero ice maker runs $3,500–$7,000. Average repair: $450. Repair wins every time.
Built-in pricing without the guesswork
Premium ice makers cost more to repair, but the pricing stays predictable — you approve a fixed quote before any work, and it's still a fraction of replacement.

Common questions
I have a Sub-Zero refrigerator, not a standalone ice maker — do you service it?
Yes. For Sub-Zero refrigerators, see the separate page. Dmitri is certified on the full Sub-Zero lineup.
Why does Sub-Zero ice maker repair cost more than a standard unit?
OEM parts cost 3–5× more than comparable Whirlpool or GE parts; the R134a circuit requires full evacuation and recharge; and built-in access is tighter than a freestanding machine. Still, a new Sub-Zero runs $3,500–$7,000 — repair for $450 is the obvious call.
How often does a Sub-Zero ice maker need descaling?
Every 6 months. Orange County's hard water accelerates mineral buildup on the evaporator. A bin that's empty before a party — while the machine sounds like it's running — is the classic early-stage scale symptom. Descaling cost: $200–$500.
Is it worth repairing a built-in ice maker?
Almost always — yes. A built-in undercounter ice maker costs $1,700–$7,000. It's integrated into your kitchen, which means replacement involves removing the cabinet panel, plumbing, drain routing, and fitting a new model. Average repair cost: $200. Even a costly $400–$800 repair is far less than a full replacement.
How often does an ice maker need descaling?
Every 6–12 months, depending on your local water hardness. Orange County water is moderately hard. Mineral buildup is the #1 cause of ice maker failure — it clogs the water distribution, reduces heat transfer, and affects ice taste. Regular descaling can add years to the machine's life.
Do you repair countertop ice makers?
No. Countertop models (GE Opal, Igloo, Frigidaire Countertop) cost $100–$400. A service call would cost more than a new unit. We specialize in undercounter built-in and freestanding models starting at $1,000.
What does the diagnostic cost?
$89 — covers the trip, visual inspection, and pressure/temperature checks. If you book the repair, $89 is credited in full. If we don't fix it, you don't pay.
Repair or buy new — how do I decide?
Simple rule: if the repair is under 40% of the replacement cost, fix it. For built-in models ($2,000–$5,000), that means repairs up to $1,500–$2,000 still make financial sense. Factor in the cost of panel removal, installation, and 2–4 weeks lead time for a new unit.
Exception: if the compressor has failed on a machine over 15 years old, we'll look at it together — sometimes replacement is the smarter call.
Do you carry parts for my brand?
Parts for mass-market brands (KitchenAid, Whirlpool, EdgeStar, GE) — in the van, same-day repair. For premium brands (Sub-Zero, Hoshizaki, Scotsman) — we order from authorized distributors, 1–3 business days. We never use generic substitutes on premium equipment.
