Sub-Zero Classic BI Code 30-8-10: Ice maker open circuit

What 30-8-10 means

For Classic BI built-ins such as the BI-36U/S, code 30-8-10 marks an open circuit on the ice maker, listed as the second device in the ice maker group. The control sent power or a signal to the ice maker and found the path broken. Inside the freezer you may see an ice maker that never cycles, cubes frozen in the tray, or an empty bin, while the rest of the unit keeps temperature as usual.

Common causes of 30-8-10

Ice maker internal circuit open
Ice maker plug disconnected or corroded
Damaged wire where the harness passes into the freezer

✓ One safe check you can try

1. Check that the ice maker switch is on. 2. Look for frozen cubes stuck in the mold; leave them, and note it for us. 3. Confirm the bin pushes all the way back. 4. Do not pull on the ice maker wiring; tell us what you see instead.

! Why to stop there

Pinpointing an open requires continuity tests on the ice maker and harness.
Removing the ice maker means working near water fittings in the freezer.
Any new ice maker must be matched to the BI control.

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.

30-8-1030-8-10 questions

Is 30-8-10 the same as 30-8-00?

They are close cousins on BI models. 30-8-00 points to the ice accessories circuit as a whole, while 30-8-10 names the ice maker itself as the open device.

Can I reset the ice maker myself?

Turning the ice maker off and on is safe, but it will not close a broken circuit. If the code stays after that, the wiring or ice maker needs testing.

Do you carry ice makers for BI units?
