Furnace error codes

Gas furnace fault codes. Codes depend on your model family, so check the model number first.

Pick your brand, then your model family

86 codes across 6 model families. The model family matters, because two furnace models from the same brand can read the same number as two different faults.

Goodman

86 codes

Goodman, Amana and Daikin furnaces run on shared control platforms, so they share code tables. The same number can mean different things on different Goodman model families.

GMVM96

26 codes · 2010s

GMVC95

23 codes · 2000s-2010s

Similar to GMVM96 but has no rollout code, which changes the safety story.

GMV / GMH / GMS / GMN

9 codes · 1980s-2000s

One shared control table covers the whole legacy group, so these series are listed together. Not every series reports every code: the GMN, GMP and GMT group stops at 5 flashes, the GDS, GHS, GMS and GKS group stops at 7, and only the two-stage GMV reports 9. Each code page states which series it applies to.

Amana

52 codes

Amana heating and cooling is built on Goodman control platforms, so Goodman model families and code tables apply.

AMVM96 / ACVM96

26 codes · 2010s

Amana units with this platform run the same control board, so Goodman publishes the codes and you are reading the same table.

AMV / GCH / GDS

9 codes · 1980s-2000s

Amana units with this platform run the same control board, so Goodman publishes the codes and you are reading the same table.

One shared control table covers the whole legacy group, so these series are listed together. Amana units in the GMN, GMP and GMT group stop at 5 flashes and those in the GDS, GHS, GMS and GKS group stop at 7, so the higher codes do not apply to every Amana in this group. Each code page states which series it covers.

APG13

9 codes · 2000s

Amana units with this platform run the same control board, so Goodman publishes the codes and you are reading the same table.

One LED counter is shared between the gas section and the cooling section, so furnace and AC codes cannot be separated.

Daikin

35 codes

Daikin furnaces use Goodman control platforms, so Goodman model families apply. Daikin VRV IV heat pumps and Daikin mini split and thermostat codes are entirely separate systems with their own code tables.

GMVM96 platform

26 codes · 2010s

Daikin units with this platform run the same control board, so Goodman publishes the codes and you are reading the same table.

GMV / GMH / GMS / GMN platform

9 codes · 1980s-2000s

Daikin units with this platform run the same control board, so Goodman publishes the codes and you are reading the same table.

Daikin-badged units in this group run the same control as the Goodman and Amana legacy furnaces, so the same table and the same per-series code coverage apply.
