Error-code hub
Goodman error codes
Goodman 20 Series public literature was checked for ductless mini-split error codes, including Goodman-owned support and literature pages, but the manufacturer does not publish a public error-code table for this line. This hub is intentionally a finding, not a guessed chart: use the exact model manual or Goodman support rather than reading codes across from another brand.

Goodman mini-splits
Use the Goodman catalog for model context. Do not apply another brand's error-code table unless the manufacturer publishes that cross-reference for your exact unit.
