Sub-Zero Classic BI Code 15-9-01: auger relay stuck closed

What 15-9-01 means

With a Classic Built-In refrigerator such as the BI-36U/S, 15-9-01 tells you the dispenser relay, which drives the ice auger, is stuck closed. The auger can keep turning without anyone pressing the paddle, pushing ice toward the chute or grinding in the bin. You might hear the auger running, find ice spilling at the dispenser, or notice the bin emptying faster than normal. Cooling usually carries on without change.

Common causes of 15-9-01

Auger relay contacts welded shut on the board
A board output stuck in the on state
Wiring holding the auger circuit live

✓ One safe check you can try

1. Remove the ice bin if the auger is pushing ice out on its own. 2. Clean up any ice or water at the dispenser. 3. Reset the breaker once. 4. If the auger runs again, turn the breaker off and call us.

! Why to stop there

A constantly running auger motor can overheat
Relay testing is done on a live board behind panels
Board replacement needs correct programming for the model

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

15-9-0115-9-01 questions

Why is my dispenser pushing ice out by itself?

With 15-9-01 the auger relay is stuck closed, so the auger keeps turning without a request. Removing the bin stops the spilling and protects the motor until the board is repaired.

Will the auger motor be damaged?

Running nonstop can overheat it, so do not leave it going. We test the motor after fixing the relay and tell you whether it needs attention.

How do you price the repair?

After diagnosis we give a written price for the board work and, if the auger motor ran hot, any further parts it needs. Our labor carries a 30-day workmanship warranty.
