Lennox XC21 Ignition Igniter
The ignition igniter in the XC21 is responsible for igniting the gas in the HVAC system. Your heating system cannot get going and establish any heat if the ignitor fails.
Easy warnings your ignition igniter has little life left
- No lighting of the LP or natural gas at the right time
- The furnace makes little to no heat when the thermostat says that it should be heating

If you are going to be buying or purchasing, do your due diligence and cross-check the model number and also make a visual comparison in order to be sure the right ignition igniter is being ordered. There is no need to install the replacement part alone. Locate a pro in your town or city to hire and install the part for you.
