I have a Payne 373LAV036070... I woke up to a cold house. I when through the process, turn power off, turn gas to off, wait 15min, and then flip breaker back on, turn gas knob to on and put doors back on. I heard and smelled gas but NO heat. The gas will not ignite. HELP

Does the igniter come on? Do you see it glowing? Do you have a flashing/code coming from led light on the circuit board, if so count the blinks and look on inside of cover/door for info on what the code is telling you
