Sub-Zero Code 30 9 86: Dispenser Chute Motor Timed Out
Sub-Zero code 30 9 86 means the dispenser chute motor failed to reach its open or closed position. Usually a jammed chute or failed chute motor.
Sub-Zero code 30 9 86 means the dispenser chute door motor timed out without reaching its open or closed position. The usual fix is clearing a jam so the chute moves freely, or replacing the dispenser assembly if the chute motor has failed.
What 30 9 86 means
A motorized chute door seals the ice path when not dispensing and opens to deliver ice. The board expects the chute to reach its target position within a set time. This code is set when that motion does not complete, indicating the chute or its motor is stuck.
Severity:Service recommended
Why 30 9 86 happens
Ice buildup, frost, or debris can bind the chute door so the motor cannot drive it through full travel. The chute motor itself can weaken or fail, and worn linkages or a warped chute flap increase friction until the motion times out.
Common causes
- Ice or frost jamming the chute door travel
- Failed or weakened chute door motor
- Debris obstructing the chute mechanism
- Worn or binding chute linkage
- Warped chute flap increasing motor load
What you'll typically see
- Chute door stays open, letting cold air and frost into the dispenser
- Chute fails to open, so no ice dispenses
- Grinding or straining noise from the dispenser during operation
- Visible frost or ice buildup around the chute opening
- Dispenser delivers ice slowly or incompletely
Parts involved in 30 9 86
- Dispenser assembly — Replace per the source guidance when the chute motor or mechanism cannot move freely after clearing obstructions
- Chute door motor — Service the motor if it is independently serviceable and the chute itself moves freely
What you can check yourself
- Inspect the chute opening for ice buildup or debris and clear it gently
- Confirm the chute flap is not blocked by a stray ice chip
- Power-cycle the unit and watch whether the chute cycles normally
- Note any grinding noise and the exact code
When to book a pro
Determining whether the chute is merely jammed or the motor has failed, and replacing the dispenser assembly if needed, requires a technician to disassemble the dispenser safely.

Frequently asked
30 9 86 FAQ
What does Sub-Zero code 30 9 86 mean?
Code 30 9 86 means the dispenser chute door motor timed out before reaching its open or closed position. A motorized chute door seals the ice path when idle and opens to deliver ice; the board expects it to reach its target within a set time. When that motion does not complete, 30 9 86 is logged, indicating the chute door or its motor is stuck.
Can I clear 30 9 86 myself?
Often you can address the most common cause, a jam. Inspect the chute opening for ice buildup or debris and clear it gently, confirm the chute flap is not blocked by a stray ice chip, then power-cycle the unit and watch whether the chute cycles normally. If it still times out or you hear grinding after clearing obstructions, the motor or mechanism has likely failed and a technician should open the dispenser.
How do I reset code 30 9 86?
After clearing any ice or debris from the chute, power the refrigerator off at the breaker for about a minute and restart it. If the chute now travels freely the code clears on the next cycle. If 30 9 86 returns or you still hear a straining noise, the chute motor is weak or the flap is binding, and the reset will not hold until the mechanism is repaired.
Is it a problem to keep using the dispenser with 30 9 86?
It is worth attending to fairly soon. If the chute stays stuck open it lets cold air and frost into the dispenser, which worsens the frost buildup that caused the jam; if it stays stuck closed, no ice dispenses. Refrigeration itself is fine, but the failure tends to compound as frost accumulates, so clear the chute and schedule service rather than leaving it.
What part fixes 30 9 86 and what does it cost?
If the chute itself moves freely once cleared and only the motor is weak, the chute door motor is serviced; if the motor or mechanism cannot move freely even after clearing obstructions, the dispenser assembly is replaced per the source guidance. We determine which on a flat $89 diagnostic and back the repair with a 365-day warranty. Call (650) 668-1554.
How is 30 9 86 different from the 30 9 10 auger open code?
Code 30 9 86 is a timeout, the chute door motor is told to move but does not complete its travel in time, often with a grinding noise and frost around the chute opening. Code 30 9 10 is an open circuit where the auger motor gets no current at all and makes no sound. The technician confirms 30 9 86 by checking whether the chute can travel freely versus whether the motor has stalled, rather than ohm-testing for an open as with 30 9 10.
