Amana AMSS920803BN Error Code 8 Flashes: Igniter Circuit Fault
What Does Code 8 Flashes Mean?
Eight flashes on the Amana AMSS920803BN report a problem in the igniter circuit. The hot surface igniter is the element that glows red-hot to light the gas burners; the Integrated Control Module monitors this circuit and flags eight flashes when it detects an open or failed igniter, a loose igniter connection, or a poor unit or burner ground.
The most common cause is a cracked or burned-out igniter. These elements are brittle and can fail from thermal stress or an accidental knock, and when one fails it usually reads as an open circuit the board can detect. Loose or corroded wiring at the igniter connector, or a poor ground on the unit or burner assembly, can produce the same code.
This code is distinct from one flash (code-1). Eight flashes is the board detecting a fault in the igniter circuit itself — often before or without a real ignition trial — while one flash is a lockout after a flame simply failed to establish or hold. A bad igniter can ultimately lead to either, which is why a technician tests the igniter and its circuit directly. Because the igniter is fragile and the work involves the burner and grounding circuits, this model classifies the repair as professional.
What You'll Notice
- The furnace will not start and the igniter never glows
- The single diagnostic LED blinks eight times, pauses, and repeats
- No heat and no ignition attempt at all
- The fault may follow a spell of longer warm-up times or intermittent ignition
- You may see a visibly cracked or blistered igniter element near the burners
Common Causes
| Cause | Likelihood | DIY? |
|---|---|---|
| Failed hot surface igniter | Most common | ✗ Call a pro → |
| Loose or disconnected igniter wiring | Common | ✗ Call a pro → |
| Poor unit or burner ground | Uncommon | ✗ Call a pro → |
How This Is Diagnosed
A technician checks the igniter's resistance and continuity to see whether it has opened, inspects the element for cracks, and examines the wiring and connector between the igniter and the control module. They verify the unit and burner grounds, since a poor ground can trigger the same code. A failed igniter or bad connection is repaired or replaced, and the control module is suspected only after those checks come back good.
When to Call a Professional
This code involves components that are not homeowner-serviceable, so have a licensed HVAC technician diagnose and repair it. Keep in mind:
- Eight flashes appear and the igniter never glows during startup
- The igniter looks cracked, blistered, or broken
- The code followed recent service around the burner area
- Eight flashes persist after cycling power to the furnace
Frequently Asked Questions
What is the hot surface igniter?
It is the small element that glows red-hot to light the gas burners on this furnace. Eight flashes mean the control board detected a problem in that igniter's circuit.
Can I replace the igniter myself?
These igniters are fragile and the job involves the burner and grounding circuits, so on this model replacement is classified for a technician who can test the circuit and handle the part without cracking it.
How long do these igniters last?
Lifespan varies widely with how often the furnace cycles, so there is no fixed figure. They are a common wear item and are replaced when they crack or read as an open circuit.
