Amana AMSS920803BN Error Code 8 Flashes: Igniter Circuit Fault
What Does Code 8 Flashes Mean?
Code 8 (8 Flashes) on the Amana AMSS920803BN indicates a fault in the igniter circuit. The hot surface igniter is the ceramic component that glows red-hot to light the gas burners — without a working igniter, the furnace cannot safely ignite the gas and will not attempt to fire.
The most common cause is a cracked or burned-out hot surface igniter. These components are made of silicon carbide or silicon nitride and have a limited lifespan, typically lasting 3 to 7 years depending on usage. They are extremely fragile and can crack from physical impact or thermal stress. When an igniter fails, it typically either cracks visibly or develops an open circuit that the control module detects.
Other possible causes include loose or disconnected wiring between the igniter and the control module, a poor ground connection on the unit or burner assembly, or in rare cases, a faulty control module. A technician can test the igniter's resistance with a multimeter to confirm whether it has failed and replace it if necessary. Hot surface igniters should always be handled with care — oils from skin contact can create hot spots that shorten the igniter's life.

When to Call a Professional
Contact a licensed HVAC technician if:
- The furnace displays 8 flashes and will not ignite — the igniter circuit needs professional testing
- The igniter does not glow at all during the ignition sequence
- The igniter glows but appears to have visible cracks
