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.

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.

“Sub-Zero 36-inch built-in with a noisy compressor. Compressor mounts were worn causing vibration. Mounts replaced and compressor serviced for $295. Fridge is quiet and cooling perfectly. Sub-Zero expertise is rare and valuable.”

“Our Samsung dishwasher was leaking from the bottom. The technician found a loose hose clamp on the circulation pump. It was a simple fix for $120 — I really appreciated the honesty since they could have sold me a new pump. The dishwasher has been leak-free since. Trustworthy company.”

“KitchenAid built-in refrigerator was forming puddles underneath. Clogged defrost drain was sending water out the bottom instead of into the drain pan. The tech cleared the drain, added a drain heater clip to prevent recurrence, and cleaned the drain pan. $175 for a fix that eliminated a really annoying problem.”

“Our LG French door refrigerator stopped cooling overnight. With a fridge full of food, we needed emergency service. The tech came same-day, diagnosed a failed compressor relay, and had it running in under an hour. He also told us about LG's compressor warranty which covered the part. Outstanding service.”

“Our 20-year-old Sub-Zero had a warm refrigerator section. The tech was clearly experienced with Sub-Zero — he diagnosed a failing evaporator fan and weak door gaskets. Replaced both, cleaned the condenser, and the unit is performing like new. $520 for a repair on a unit worth $15K+ to replace. No-brainer.”

“The technician arrived within 2 hours of my call and diagnosed the issue immediately — a faulty defrost timer causing ice buildup. He had the part on his truck and fixed it in under an hour. My fridge has been running perfectly for 3 months now. Very reasonable price at $275.”

“GE upright freezer was running but not getting below 25°F. The evaporator fan motor was failing. Tech replaced it and also checked the defrost system which was still working fine. $210 total and the freezer is back to 0°F. Saved about $800 in frozen food that would have spoiled. Worth every penny.”

“Our chest freezer stopped freezing and we had hundreds of dollars of meat inside. Called at 8am and the tech arrived by 10:30am. Faulty thermostat was the culprit — replaced in 30 minutes. Saved all our food! Cost was $175. Can't thank them enough for the fast response.”

“Finding someone experienced with Sub-Zero was tough until I found this company. Our 15-year-old Sub-Zero was running constantly and not cooling. The tech cleaned the condenser, replaced the fan motor, and it's been running like new. Worth every penny of the $450 repair — a new Sub-Zero is $12,000+.”

“The notorious Samsung ice maker problem struck our French door fridge. The tech was very familiar with this specific issue, performed the recommended fix including defrosting the evaporator and installing a new ice maker kit. It's been 6 weeks and still working great. $350 well spent.”
