Sub-Zero Classic BI Code 15-8-10: ice accessories relay open

What 15-8-10 means

Classic Built-In models like the BI-36U/S use 15-8-10 for an ice accessories relay that is stuck open. It is also known as the ice maker second device relay, the one that powers the extra ice-side device beyond the ice maker itself. With it stuck open, that device gets no power when the board calls for it. Expect the ice side to work only partly, while cooling elsewhere goes on normally.

Common causes of 15-8-10

An ice accessories relay that will not close
A loose connection from the board to that circuit
A control board needing repair

✓ One safe check you can try

1. Confirm the ice maker is switched on. 2. Check that the bin and any dispenser parts are seated correctly. 3. Reset the breaker one time. 4. Note which ice functions work and which do not; tell us when you call.

! Why to stop there

The relay sits on the powered control board
Telling which ice device is affected takes testing at the board
Swapping ice parts will not fix a relay that sends 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.

15-8-1015-8-10 questions

What is the ice accessories relay?

It is the second relay on the ice side of a Classic BI board. It powers an extra ice device separate from the ice maker. When stuck open, that device does nothing.

Does 15-8-10 mean the main ice maker relay failed?

15-8-00 is the main ice maker relay stuck open. 15-8-10 is the second, accessories relay stuck open. The ice maker itself may still make some ice with 15-8-10.

Is food at risk?

No. This relay only affects the ice side. Cooling keeps running, so you can book the visit when it suits you. We give a written price before any work.
