GE Appliances mini split error codes
GE Appliances ductless multi-zone systems are built by Haier (GE Appliances' parent) and share the Haier table: numeric codes on the Service Monitor Board inside the outdoor unit.
Covers: GE multi-zone ductless (ASH…JCDDA).

No code matches that. Check the characters (b and 6, 0 and o, and E and F are easy to confuse) or try another brand.
How GE Appliances shows error codes
These numeric codes show on the Service Monitor Board display inside the multi-zone OUTDOOR unit (behind the service panel). The indoor units signal a fault with blinking lamps; the number on the outdoor board is what identifies it. Codes 1 to 27 are outdoor-unit faults and protections, 28 to 41 are temperature sensors (28 to 31 and 40 are zone liquid-pipe sensors, 32 to 36 are zone gas-pipe sensors), and 42 to 45 are pressure switches and limits.
Brands built on the same platform
These brands share a code table with GE Appliances because the same factory builds them, so their pages describe the same faults: Haier.
