I have a Rheem furnace in my house. It recently stopped working.
It is the type where the pilot is not always on. Anyways, the ignition will kick in, and the pilot lights just fine. However, the spark ignition just keeps going and the main burners never turn on.
Unless I am mistaken, this furnace does not have a flame sensor, so I'm at a loss for what could be the problem. Any help is appreciated!
