More frustration--now the heater is working well...when it works! Most of the time the heater is functioning properly, but occasionally, the burner does not light and the blower continues to blow cold air and does not stop until we wake up freezing. Once the heater is shut off for a few minutes, it will light correctly. I replaced the sail switch, and the limit switch, and I removed the burner and cleaned all of the debris with a vacuum. But none of this has fixed the problem. It still occasionally does not light and the fan continues to run. There is not much left to replace. My next step is to replace the ignitor, and if that does not fix it, I guess I will replace the circuit board.
