Sub-Zero Classic BI Code 15-9-00: dispenser auger relay open

What 15-9-00 means

Classic Built-In units with a through-door dispenser, like the BI-36UFD/S, show 15-9-00 when the dispenser relay is stuck open. This is the auger relay, which powers the auger that pushes ice from the bin to the chute. With the relay open, pressing for ice does nothing even though the bin may be full. Water dispensing and cooling are on separate circuits, so they usually keep working while the code is present.

Common causes of 15-9-00

An auger relay on the control board that will not close
A loose plug between the board and the auger circuit
A control board that needs repair

✓ One safe check you can try

1. Check the bin for a solid clump of ice that might jam the auger and break it up gently. 2. Make sure the bin is pushed fully into place. 3. Reset the breaker once. 4. Try the ice paddle again after power returns.

! Why to stop there

The relay is on the powered control board
Testing auger power means accessing wiring behind panels
Replacing the auger motor will not help if it gets no power

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.

15-9-0015-9-00 questions

My bin is full but no ice comes out. Is this 15-9-00?

That is the typical sign. The auger relay is stuck open, so the auger never turns. Water may still dispense normally because it uses a different circuit.

Could a clump of ice cause this?

A jammed bin stops ice too, but 15-9-00 itself points to the relay. Breaking up clumps is still worth doing, and we test the relay to confirm.

What happens during the visit?

We check auger power at the board and the plug, repair the relay side, and test ice dispensing. You receive a written price before we begin.
