Sub-Zero refrigerator ice maker not working is a known issue affecting BI-36U/S. Our technicians specialize in Sub-Zero-specific diagnostics and repair.
Our Sub-Zero fridge stopped cooling right before a dinner party in our Noe Valley home. The technician arrived within two hours, diagnosed a faulty compressor relay, and had it running perfectly before guests arrived.
Sub-Zero refrigerator ice maker not working is typically caused by frozen water line or failed water inlet valve. Sub-Zero-specific factor: water inlet valve solenoid calcification from hard water restricting flow to the low-pressure fill system. Repair costs $100-$350 with free diagnostic and 90-day warranty.
Water inlet valve solenoid calcification from hard water restricting flow to the low-pressure fill system
Fill tube heater failure causing ice blockage at the fill tube entrance — progressive until complete stoppage
Ice maker motor harvest cycle stall from worn gear teeth on units with 8+ years of use
Icemaker arm signal sensor misreading full bin due to ice bridging between cubes in the bin
Frozen fill tube from defrost drain condensation migrating to the ice maker area in high-humidity environments
Other Sub-Zero models may also be affected. Book a free diagnostic for confirmation.
Seeing one of these codes? It likely indicates ice maker not working.
Sacramento hard water (180+ ppm TDS) calcifies Sub-Zero inlet valve solenoids within 18-24 months, producing hollow or undersized crescent ice before complete failure. Roseville and Folsom homes on municipal well-blended water see the fastest deterioration. Installing an inline filter at the supply line during repair extends valve life by 3-4 years.
Check water supply pressure at the refrigerator connection — Sub-Zero requires 20-30 PSI minimum for proper fill cycle
Inspect fill tube for ice blockage by removing the ice maker assembly — a frozen tube indicates heater failure (SZ-4200810)
Force an ice maker test cycle via the diagnostic button and verify water valve clicks open and delivers 7 oz in 7 seconds
Examine the ice bin for bridging between cubes — humidity causes cubes to fuse, triggering a false full-bin signal
The technician removes the ice maker assembly to inspect the fill tube and harvest mechanism. Mineral buildup on the inlet valve screen is cleaned or the valve replaced (SZ-4201940) — a 30-minute repair. Fill tube heater replacement requires accessing the back of the freezer compartment, routing new wiring through the harness channel, and verifying heater operation through one full freeze cycle.
