Amana AMSS960803BN Error Code 8 Flashes: Igniter Circuit Fault
What Does Code 8 Flashes Mean?
Code 8 (8 Flashes) on the Amana AMSS960803BN indicates a problem with the igniter circuit. The hot surface igniter is the component responsible for lighting the gas burners — it heats to approximately 1800 degrees Fahrenheit to ignite the gas. Without a functioning igniter circuit, the control module will not open the gas valve and the furnace cannot heat.
The most frequent cause is a failed hot surface igniter. These are ceramic components (silicon carbide or silicon nitride) that become brittle over time and eventually crack or develop an open circuit. A cracked igniter may show visible damage, or it may look intact but have an internal break that prevents current from flowing. Igniters typically last 3 to 7 years with normal use.
Other causes include loose or disconnected wiring between the igniter and the control module, a poor electrical ground on the furnace chassis or burner assembly, or a faulty control module that cannot properly send power to the igniter. A technician can measure the igniter's resistance to determine if it has failed and replace it if necessary.

When to Call a Professional
Contact a licensed HVAC technician if:
- The furnace shows 8 flashes and will not ignite — the igniter circuit requires professional testing and repair
- The igniter does not glow red-hot during the startup sequence
