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.
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.

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.
Bay Area Sub-Zero ice maker issues frequently trace to Hetch Hetchy water supply, which despite being soft has seasonal turbidity spikes that deposit fine sediment in the inlet valve screen filter. Peninsula homes with older copper supply lines add corrosion particles. The technician cleans the valve screen filter (SZ-4201940) during every ice maker service call as standard practice.
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.

“My exprience with Easy Bear was absolutely superior from the beginning. I had a Subzero decide to quit. Daniel assessed the issue immediately, ordered the required new " motherboard" and had it installed within three days. My prior replacement of said part took 5 months during Covid. Daniel is smart, professional, clearly knows his trade . I most definitely will use Easy Bear in the future.”

“Daniel the technician came to diagnose what's causing our washing machine water overflowing. He didn't actually have to do anything to solve the issue, because as soon as he turned it back on, it began to work properly, but explained what the probable cause was. He was sincere and clear on the matter related to the situation. I wasn't charged for his visit as I was told ahead of time. Stanislav was also cordial arranging for all of the process. I will call them next time I need an appliance service without hesitation.”
