You have a system that is 20 years old. The cost of the repair may be 1/2 of a new unit. This unit will continue to fail and only cost you more that you can expect to get out of it.

I cant see your wire diagram but trace the circut your talking about. I believe it usually goes through a series of safety switches. Put your VOM across each individual switch. If you get 24 out from the board the first 1 you check and get 24v is open and not feeding back to the board is out. FIND out why. the switch could be bad but it may be indicating a more involved problem, just look aroeund for chared wires or tell tell signes of flame roll out or if its an open (fuse link) suspect what can cause an over heat condition anythign from a bad board or too long an off cycle before the indoor fan comes on ect. PONIT IS Once you come across the cause may not be the reason.
Please grade me accordingly and if you need more I need more info from you.

Sounds like the flame sensor is dirty or bad. This sits in the burner flame when the burners are running. This usually has a single white wire connected to the back of it.

disconnect the thernostat wires from the control board. Put a jumper wire between R & G put door back on and turn on power. Blower motor
should run, if it blows the fuse then you have a direct short between R &
G at the board. Do this with R and W(heat) and R & Y(cool).
By disconnecting the thermostat wires and reinserting them make sure that they do not touch when inserted into each terminal. If it still blows
that little 3amp fuse when jumpering between each sequence as mentioned above, then I think your board is bad. When Jumpering out the Y terminal you will have to have the AC wires still hooked up. If it
blows the fuse in that sequence. Disconnect the wires out at the condensor.
You mat have a bad contactor at the outdoor unit.
