I have a goodman propane furnace that will ignite intermittently. The hot surface ignitor will some to a hot red glow, and then the burners will not light. It will cycle through the next time and some times will then ignite. If it doesn't ignite, I will flip the breaker, give it a few minutes and then flip it back on. It will usually ignite the 3rd or 4th time, but I would prefer it light correctly the first time. I have taken the flame sensor off and lightly sanded it, I have made sure all of the propane orifices are clean and open. I am just not sure where to go from here. Any help would be grateful, thank you

Sounds like you have dirty burners. You will have to remove the burners and clean them with a wire brush. Turn off power and gas before service.
