Goodman six flashes: a rollout trip and a wiring fault on one count
What Does Error 6 flashes Mean?
Six flashes is a count that Goodman has assigned differently on different integrated controls, including a flame rollout trip on some and a line voltage polarity or grounding condition on others. Because those two readings have completely different risk levels, the diagnostic label inside your own furnace door decides which one applies, not a chart found elsewhere. Applies to: Goodman GMVC-series and related integrated furnace controls documented in the installation and operating instructions Goodman publishes the flash-count table on the wiring and diagnostic label of each furnace and in that model's installation and operating instructions. The count-to-meaning mapping is a property of the control platform, so a table from a different Goodman generation, or from Amana equipment on a related control, can be wrong for your furnace. Owner-safe checks: Read the diagnostic label inside the furnace door through the sight glass or during a permitted access, and record what six flashes is assigned to on that control. | Look and smell for soot, scorching, or combustion odours around the furnace without opening the burner compartment. | List any electrical work, supply changes, or generator use in the period before the code appeared. Qualified technician: A flame rollout trip requires combustion, heat exchanger, and venting assessment by a licensed gas engineer, and the reset button on a rollout device is not an owner control. | Correcting line voltage polarity or a grounding fault at the furnace supply is electrical work for a qualified person, not a matter of swapping conductors on a guess.
