Sub-Zero Classic BI Code 15-8-11: second ice relay stuck on

What 15-8-11 means

On a Classic Built-In refrigerator such as the BI-36UFD/S, 15-8-11 means the ice accessories relay is stuck closed. This is the ice maker second device relay, and in the closed state it keeps powering that extra ice-side device even when the board says stop. Owners may hear a device on the ice side running longer than usual or notice ice behaving oddly. Cooling in the fresh-food and freezer sections typically continues without trouble.

Common causes of 15-8-11

Relay contacts stuck together on the board
A board output failing in the on position
Wiring that keeps the accessories circuit powered

✓ One safe check you can try

1. Switch the ice maker off to reduce run time on the ice side. 2. Clear any ice jams you can see in the bin. 3. Reset the breaker once. 4. If 15-8-11 returns, leave the ice maker off until we visit.

! Why to stop there

A device that runs constantly can overheat
Relay testing happens on a live board
The board may need replacing with correct programming

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.

15-8-1115-8-11 questions

Why does something on the ice side keep running?

The second ice relay is stuck closed, so its device stays powered. Turning the ice maker off reduces wear on that device and on the ice maker until the board is repaired.

Is 15-8-11 the opposite of 15-8-10?

Yes. 10 means the accessories relay is stuck open and the device gets no power; 11 means stuck closed and it never stops getting power.

Does the repair come with a warranty?

We also check that the ice maker and its second device cycle properly after the fix. You approve a written price first, and a 30-day workmanship warranty covers our labor.
