    Aireflo Furnance with Honeywell SV9520H8042 gas valve not starting up properly

    My furnace is not starting up properly, it tries to start up, fan runs for few seconds and then turns off and cycle continues.
    It has Honeywell SV9520h8042 valve.
    After opening the cover and letting it run for few "attempt" cycles, found out that few seconds after fan starts, an orange bright light (pilot flame supposedly) turn on, stays on for few seconds, then turns off.
    I tried basic troubleshooting, turning gas off/on, turning valve off/on, unplugging and plugging wire harnesses in the valve.
    What should I do ?

    pick up the phone, call your servicing contractor.
    It`s better to be silent and thought the fool; than speak and remove all doubt.
