You replace any electronics on that board and you will void any homeowners policy you own.Very strange for both the draft inducer pressure switch to go bad and the control board to short out. In the board picture it looks like a disc capacitor but is more than likely a MOV suppressor - did your circuit breaker trip? depending where the surge came from the board may still be good, try clipping the MOV out of the circuit and resetting the breaker. They are only a dollar and if proved can be replaced later.
The control board must see that pressure switch initially open before starting the sequence then closed after the fan starts - this is so you can't trick it with a jumper wire. After seeing the board I doubt its bad.
And as DM said make sure your lines are clear on the switch.
Contact the mfg of any HVAC brand. They'll confirm what I told you.that's hilarious, thanks - grins back at ya

Controls are not rebuilt for a darn good reason. When a new furnace model is safety certified it is with the components that the mfg hast designed in to it.
Any field alterations would be considered a deviation (that means repairing a board or any other part of the safety or ignition system) from the original design and puts the liability squarely on the shoulder of the offending individual.
There was a guy around here who was repairing Bryant blower boards some years ago for local wholesaler. UTS shut 'em down hard. And rightfully so.
The solid state components were generic and not the same quality the OEM put into to the board. There were a few cases of gas valves not closing on the end of a cycle.
I ran those calls and they were the repaired boards I mentioned.
