Goodman fault codes

40 documented codes for Goodman furnaces and air conditioners, each cited to the manufacturer's own manual. Goodman and Amana are both Daikin Comfort Technologies brands built in Waller, TX on the same platforms and the same integrated control boards. One installation manual covers both, using a wildcard model number (for example *MVC96 = GMVC96 and AMVC96), so a code means the same thing on either brand. Daikin-branded furnaces of the same generation use these controls too..
