Customer Question

I Have a gas furnace brand is unknown and it wont run. Its been un powered all summer and when I powered it up the LED light only stayed on for about 2 seconds. So I turned the breaker off then back on and the same thing 2 seconds on then it goes off. Any ideas or just change the circuit board?
