I have a goodman furnace. Recently the hot surface ignitor and flame sensor crapped out. I replaced both and everything worked fine for two months. Now I am not getting any flame. I checked the flame sensor and that is not the problem.
The circut board flashes once which the troubleshooting chart reflects flame sensor or gas valve,gas flow or gas pressure. How can you determine which of the gas problems it could be?
I have a gas water heater and have no problem there with the gas.

Sounds like you have a control board going out.
Turn off power to the furnace and then turn power back on. By doing this you are resetting the control board. Then try to start the furnace to see if it works.

Turning off and then on again did not help so I guess I will look for some one who will sell me a new board.
