Goodman GMVC960804CN 96% AFUE 80,000 BTU Two-Stage Gas Furnace MECH-IGNITER Error Fix: Failed Hot Surface Igniter

The hot surface igniter (HSI) has cracked from thermal cycling and age — it will either not glow at all (open circuit = 8-FLASH) or glow too weakly to open the gas valve; silicon nitride igniters last 3-5 years typically; replacement is a $15-40 part with 2 screws and a plug connector; do not touch the new igniter element with bare hands (oils cause hot spots)
