Furnace Fault Codes

Amana AMEC96 furnace fault codes

Every diagnostic code Amana publishes for the AMEC96 series — 24 of them — taken from the manufacturer's own per-model fault code database rather than from a general table.

Codes differ between models from the same manufacturer, which is why this list is worth reading in preference to a brand-wide one. Six flashes means a rollout switch on some Goodman models and a rollout limit or a blown control module fuse on others. A count that appears on one board may not exist on another at all.
