Goodman mini split error codes
Goodman is a Daikin company, and its current e-Series mini splits carry Daikin's own FTXN / RXN model numbers: they are Daikin-built and use Daikin's code set, read from the remote controller's self-diagnosis. Goodman's earlier MSH, MSC and MSG mini splits (2008 to about 2020) came from a different maker and are not covered here.
Covers: e-Series wall-mount (FTXNG indoor / RXNG outdoor).

How Goodman shows error codes
Most Daikin wall units do not show the code on the unit; the operation lamp blinks. To read the code, point the remote at the unit, hold CANCEL (or Timer Cancel) for about 5 seconds until 00 shows, then press CANCEL repeatedly. Each press shows a code; when the unit gives a long continuous beep instead of two short beeps, the code on the remote is the stored fault. Units with a wired controller show the code directly. A and C codes are indoor-unit faults, E, F, H, J, L and P codes are outdoor-unit faults and protections, and U codes are system-level problems such as communication, power supply and refrigerant shortage.
Brands built on the same platform
These brands share a code table with Goodman because the same factory builds them, so their pages describe the same faults: Daikin.
