Furnace problems

yesterday my propane ran out so i went and refilled it and got evrything turned back on and now the fan will run and the furnace will ignite and heat starts running for about 10 secs and then shuts off. i reset the thermostat by turning it off and back on again and the problem continues. It will ignite and run for 10 secs and during that time i hear rapid ticks and then it will shut off again> that will continue for 3 times and then it stops igniting. Thanks for any advice recieved

    When you ran out of propane you probably didn't turn off appliances that were using the propane, so propane lines were depleted of any pressure
    So when you refilled you cylinder and then valved it into service the demand downstream caused the excess flow device to trip


    Close service valve....wait 30 sec. then SLOWLY open service valve
    Turn on stove top burners on high to PLACE A DEMAND on REGULATOR and ESTABLISH FLOW (there is no air to bleed/purge)

    With stove top burners in service try furnace again...
    It may take a few attempts to get flow established at furnace
    (Furnace is shutting down due to lack of 'Flame Proving' cause falme is not lighting off due to lack of propane flow)




    And how come you ran out.......do you only have one propane cyclinder??

    I agree with opening the valves slowly, but I would go a step or two further.

    Turn off the tanks.
    Disconnect the lines from the tanks.
    Try to light the stove with the lines disconnected. (getting) pressure out of the lines.
    Turn off the stove.

    Reconnect the lines.
    Turn the valves on VERY SLOWLY until you hear the valve click then you can open them up.
    Go light the stove again.

    Once the stove purges the air out of the lines then try the furnace again.

    sounds like something is stopping up the airflow. I live in the delta and we have lady bugs terribly bad. They've gotten into my exhaust before and completely clogged the furnace. I had to have furnace taken out and cleaned to make it work again. Could also be a dirt dauber clogging it.

    You have air in the line. Bleed at the range top burners until they light. Then furnace should light.
