    Wha about the rest of the table?

    Like red to yel, red to white, red to green etc.

    Did you wait long enough to see if the burners ignited.

    The furnace should not turn on with the wires of the tstat disconnected. If it does, then there is something wrong.

    If the furnace turns on with no tstat wires connected then,

    1. The wiring is faulty from the tstat to the furnace -or-
    2. The blower relay is stuck closed.

    You have to disconnect the wires at the furnace.

    Wires disconnected at furnace
    1. blower turns on (see more troubleshooting)
    2. Blower off; wiring issue

    More troubleshooting

    1. blower relay
    1a If blower relay mounted on control board - replace control board
    2. Limit control

    I think you made the right decision to have it professionally looked at. Your pics indicate that the unit has not been serviced for quite some time. There is too much dust.

    In your last pic, I see that your thermostat wires are connected directly to the transformer(left of the gas valve, mounted on a four by four metal box. Wright down where these wires go, and unhook them all. Now see if blower runs when power is turned on to furnace. Im betting you have a short in your thermostat wires between stat and furnace, or you have a bad transformer. At this point I agree that you would be best to call in an onsight tech. However if you disconnect the t stat wires from the transformer in furnace, it will help us gain a little more knowledge about your problem. Good luck and please let us know how things turn out.
