I came back from vacation to a cold house. Main board had a hole the size of a quarter in it, at the 7 pin connector between 3 and 4. Ruined the connector also. Replaced the board and repaired connection. Furnace is still dead. Remove inducer board solenoid cover, push solenoid manually inducer motor runs, pilot starts, main fan starts, but main gas never starts. I pretty sure I need a new inducer board for starters any suggestions, what's next. Thanks Doug

If you have 24 volts on the orange wire going to the inducer relay board as well as 120 volt between the white and black at same connector and no 120volt going to inducer mtr. The inducer relay board is bad... fyi new board may need new wire installed in last pin at end, if not present already(#7 if memory serves me) of connector to relay board, from there to one of the red wires to the main limit located somewhat behind the gas control valve. If red wire is not installed new inducer control board will not work. Red wire is supplied with new inducer board. It adds a post purge feture to the inducer motor.
Now it takes a long time for the pilot to turn on the main burner... up to 3 min. If pilot is on for about 3 min. and main burner does not come on the pilot assembly needs to be replaced. Sometimes tapping on pilot wile lit will get it to fire. Still recommend replacing it. After you get done sticking all that green into it you will prebill need a new secondary heat exchanger as well. Unless been replaced secondary in last 7 years if not Recommend you bit the bullet and replace furnace, of course if you could you would. I understand.
Have Fun!
