Ignition Problems: Issues with the ignition system, such as a faulty igniter, dirty burner, or gas valve problems, can prevent the furnace from igniting properly.
Lack of Fuel: If there is a problem with the gas supply, such as a closed gas valve or an empty propane tank, the furnace may not be able to ignite.
Ventilation Issues: Blocked or restricted vents can affect the air intake and exhaust, leading to poor combustion and triggering the lockout.
Thermostat Problems: A malfunctioning thermostat can send incorrect signals to the furnace, causing it to fail to ignite.
