OEM Lennox Ignition Blower Control Board — 16V29

The genuine OEM Lennox 16V29 ignition blower control board manages the critical timing between ignition, gas valve operation, and blower motor activation in your Lennox furnace. This board sequences the entire heating cycle — from ignitor warm-up through flame verification to blower on/off delays — ensuring safe, efficient, and quiet operation. It is engineered specifically for compatible Lennox equipment, so pinouts, firmware timing, and safety logic match your system exactly.

Common failure symptoms include a furnace that ignites but never runs the blower, short cycling, no response at the thermostat, an ignitor that fails to glow, or diagnostic LED fault codes. Corroded terminals, blown onboard fuses, cracked solder joints, and heat-stressed relays are typical causes of a failed board.

Why OEM matters: generic or aftermarket boards often use different relay ratings and timing sequences that can trigger nuisance lockouts or compromise flame-safety logic. The Lennox 16V29 is a direct factory replacement that preserves rated performance and protects your warranty. Restore dependable heat with a board built to your furnace's exact specifications.
