Every common Goodman fault code with what it means, the likely cause, and how CANRO Heating & Cooling fixes it — servicing Goodman gas furnaces, air conditioners and heat pumps across Greater Vancouver since 1999. Licensed Technical Safety BC contractor (gas LGA0043870 · boiler LBP0046450).
Goodman furnaces flash an amber diagnostic LED on the integrated furnace control (count the blinks). Goodman, Amana and Daikin gas furnaces share the same control board and codes.
Important: One power-cycle reset is generally safe for a transient fault. If the same code returns within minutes, stop resetting — lockouts exist to protect the heat exchanger, ignition system and gas-valve safety circuit. Note the exact code and call CANRO at (604) 359-1081. We carry common Goodman parts on every truck, so most code-triggered faults are fixed in one visit. Smell gas? Leave and call the gas utility emergency line first.
