Lennox CB29M-31 Ignition Igniter
The ignition igniter in the CB29M-31 is responsible for the lighting of the main heating fuel in your system. It is not possible for the furnace to get going and provide heat if this igniter does not work.
Subtle hints the igniter should be replaced
- No burning of the LP or natural gas during the ignition cycle
- Furnace makes zero heat even though the thermostat is set properly
