Amana Furnace Code 10
Hard lockoutShown as: 10 flashes, then a pause, repeating
Open fuse. The 3 amp fuse on the control board has blown, so there is no 24 volt power to the control and the furnace will not run.
Manual wording: “Open Fuse / No 24V power to integrated control module”
Documented for: Amana AMES80, ACES80 (PCBBF145 control board)
Likely causes, most common first
- High voltage surge blows off the fuse
- Short in the 24 volt low-voltage wiring
What you can safely check yourself
- Check that the furnace breaker in the electrical panel has not tripped, and reset it once if it has
When to call a technician
Replacing the control board fuse without finding the short that blew it just blows the next fuse. Have a technician find the fault.
A Amana furnace throwing this code repeatedly has a reason — clearing the code without fixing the cause just hides it.
