Amana Furnace Code 8
Hard lockoutShown as: 8 flashes, then a pause, repeating
Igniter relay fault. The control board detected a problem with the relay that powers the hot surface igniter, so the furnace will not run.
Manual wording: “Igniter Relay Fault”
Documented for: Amana AMES80, ACES80, AMSS92, AMSS96, ACSS96
Likely causes, most common first
- Improperly connected igniter
- Bad igniter
- Poor unit ground
- Poor burner ground
- Faulty integrated control module
What you can safely check yourself
- Turn the furnace off at its power switch for about 30 seconds and back on once to see if the code clears
When to call a technician
Igniter, ground wiring and control board diagnosis are technician work.
A Amana furnace throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.
