What 30 8 10
actually means.
On Classic (BI) built-in models, 30 8 10 means the main control found the ice maker circuit open. With the circuit broken, the ice maker cannot run its heater or motor, so harvest and refills stop.

What to do when 30 8 10 shows on the ice makerKind of codeControl board and communication
The boards that run the ice maker stopped hearing each other, or one of them failed: the main control lost contact with the dispenser panel or the ice maker module, or a board reported an electrical problem of its own. Water that dripped onto a connector and a loose harness are checked before a board is ordered by model number. If the ice maker keeps tripping the breaker, leave it off until the visit.
Usually leads toIce maker control and sensor repair
The control board, the thermistors, the bin sensor and the wiring that decide when an ice maker fills, freezes and stops, tested and repaired when a light flashes, a code shows, a breaker trips or the ice never stops coming.
Shows up asNo Ice Coming From the Ice Maker
The mold sits empty or holds one frozen batch that never drops, the bin stays bare for days, and the dispenser gives water as usual: an ice maker not making ice while the rest of the appliance carries on normally.
