Question about Heating & Cooling
It starts for about 2 seconds, then starts again for about 2 seconds, then shuts off. After about the 3rd time it tries to start, the furnace makes a thump sound and blower kicks in and runs for about 15-20 seconds and then completely stops.
First let me thank all the pros that take the time to answer our questions. My wife thinks I'm a genious. I had the same problem up to 30 minutes ago and fixed it from a solution found on a different webpage. There's sensor sticking up where the flames come out with a single wire coming from it. Remove the sensor and scrub it with steel wool. Replace it and get your hummer from the old lady because you just saved her a few hundred bucks.

The reason why it stops and starts is that the sensor within the burner can not sense a flame in the furnace. The parts need to checked is the fuel filter, Air in the line, burnt out arcing rods or a bad ac high voltage transformer.
