Do you hear a small blower start inside of furnace? When was last air filter was changed
I didn't see any. I did find a thermo sensor on the fan drum that was tripped. When i reset it the furnace fired. However, the sensor keeps tripping. I have jumped the sensor, and waiting for the unit to refire.
I had to order a new limit sensor, which I installed on the unit last night. However, it did not solve the issue. The furnace fires up fine, but will only run for a couple of minutes before tripping the sensor again.
