Furnace not igniting

[jahebner]

My furnace is not igniting. It is a 5 year old Lennox. I discovered that the circuit breaker had tripped while trying to figure out why the furnace was not running. I reset the circuit breaker and the furnace fan is running but the gas burners still will not ignite. The house temp is down to 63 and set the heat to 75 but no luck. The other weird thing is even if I turn my thermostat off, the furnace fan continues to run. The only way to turn it off is at the power supply switch. I tried resetting the ignition per the manual but no luck. Thoughts?

You probably have one of the safety's tripped in your furnace or a maybe even a bad control board being it is 5 years old. If you are mechanically inclined, search the database on this subject here and if you are not mechanical - call a pro
