Sub-Zero Code 30 9 10: Dispenser Auger Open Circuit
Sub-Zero code 30 9 10 means an open circuit in the dispenser auger motor. Check wiring and auger ohms; usually a failed auger motor or broken connection.
Sub-Zero code 30 9 10 means the control detected an open circuit in the dispenser ice auger motor path. The usual fix is repairing the auger motor wiring or replacing the auger motor when its windings read open.
The meaning of 30 9 10
The board checks continuity to the dispenser auger motor that pushes ice from the bin to the chute. An open circuit means current cannot reach the motor, so it will not drive the ice. The result is a dispenser that no longer delivers ice on demand.
Root causes behind 30 9 10
Auger motors endure repeated start and stall loads, and their windings can open with age or after a jam-induced overheat. Connectors in the freezer door or bin region corrode or work loose from vibration and cold cycling, and harness wires can fatigue and break at flex points.
Signs of 30 9 10
- Ice does not dispense even though the bin is full
- No motor hum when the dispenser pad is pressed for ice
- Water still dispenses but ice does not
- Auger appears stationary inside the bin
- Intermittent ice delivery before total failure
Most-likely causes
- Auger motor winding open from age or overheat
- Broken or fatigued wire in the auger harness
- Corroded or disconnected auger motor connector
- Failed motor due to a prior ice jam
- Damaged door-to-cabinet wiring at the hinge flex point
The part usually behind 30 9 10
- Dispenser auger motor — Primary part when motor windings measure open or infinite resistance
- Auger motor wiring harness or connector — Repair or replace if the open is in the wiring rather than the motor
Safe owner checks
- Confirm the ice bin is seated correctly and not jammed with fused ice
- Remove and inspect the bin for clumped ice blocking the auger
- Power-cycle the unit and retest ice dispensing
- Note the code and whether water still dispenses normally
When professional service is needed
Measuring auger motor ohms and isolating an open between the motor and the wiring requires removing the bin assembly and metering the circuit, which a technician should perform.
Frequently asked
Common questions about Sub-Zero 30 9 10
What does Sub-Zero code 30 9 10 mean?
Code 30 9 10 is a dispenser auger open-circuit fault. The auger motor is what turns the auger to push ice from the bin into the chute, and the board checks continuity to that motor. An open reading means current cannot reach the motor, so the auger will not turn and the dispenser stops delivering ice even when the bin is full.
Can I resolve 30 9 10 on my own?
You can rule out a simple jam first: pull the ice bin, confirm it is seated correctly and not packed with fused ice that is blocking the auger, then power-cycle the unit and retest. Note whether water still dispenses while ice does not. But if the auger stays dead after clearing any ice, measuring the motor windings and isolating the open requires removing the bin assembly and metering the circuit, which is a technician job.
How do I clear code 30 9 10?
A breaker power-cycle clears the stored 30 9 10, and if a jam had stalled and tripped the motor, freeing the ice and restarting may restore dispensing. However, if the auger motor winding has gone open or a harness wire has broken at a flex point, the code returns the next time you call for ice and holds until the motor or wiring is repaired.
Is it safe to keep using the refrigerator with code 30 9 10?
Yes. This affects only ice dispensing, the refrigerator and freezer cool normally and water still dispenses, so there is no safety concern. A telltale sign of 30 9 10 is that water comes out but ice does not, with no motor hum when you press for ice. You can keep using the unit and schedule service to restore ice on demand.
Which part fixes 30 9 10 and what is the cost?
The primary part is the dispenser auger motor when its windings measure open or infinite resistance; if the open is in the auger harness or a corroded connector instead, the wiring is repaired. We confirm which by metering the motor on a flat $89 diagnostic, and the repair is backed by a 365-day warranty. Call (650) 668-1554 to book.
How can I tell 30 9 10 apart from the 30 9 86 chute timeout code?
Code 30 9 10 is an open circuit in the auger motor, so the auger never turns and you hear no motor hum; the giveaway is water dispensing while ice does not. Code 30 9 86 is a chute door motor that times out reaching its open or closed position, often with a grinding noise and frost around the chute. A technician confirms 30 9 10 by ohm-testing the auger motor windings, whereas 30 9 86 is about whether the chute door can travel freely.
