Lennox 72W41 Motor 322056-301 Electronic Fail-Safe: Integrated capacitor-driven safety

Electronic Fail-Safe: Integrated capacitor-driven safety return provides reliable performance without the mechanical fatigue of traditional springs

Replacing a brittle 780643 igniter with this genuine 100165926 HVAC part stabilizes resistance and prevents the nuisance 3-flash flame failure errors common in aging Power-fin and Knight-style units

Contractors often report "rumbling" or "pulsating" during the ignition phase

the 165302 head mechanism features a robust 10-bolt flange design that ensures a leak-proof seal under extreme thermal cycling

Built for rigorous heating cycles
