Ignition Problem - NG Fireplace

That board is done.
Triple check all the wiring, make sure none are shorted to ground. It may have been a fault in the board also, like a transistor shorting out internally.

But before you hook up a new one, verify the wiring/continuity/shorts to other wires/ground.
If you do not know how to do that - you need a pro.

(I used to fix high power audio amps - so my suggestions may mean nothing to you!)

Not abnormal for a transformer to make noise.
I would wager that the transformer is fine.

You will need at the very least a new control board. If you knew what the resistance was on the control valve, you could check that with an ohmmeter.

Do not split the valve, I would think it would be junk at that point.

Also, did you replace the valve with the EXACT same part? Wire it correctly?

Okay.. so could this be the problem???? See attached pictures...

What would cause the resister to fry like this? The actuall insulation of the resister is powder.

Wow never seen one with carbon deposits. I'm guessing you either had a power surge or more likely the current for the igniter leaked inside the control board. Igniters use about 1000 volts for most systems, and EMI (electro-magnetic interference) has been an issue at one time or another on a few of the IPI valve systems I've worked with. If it's all inside the board then IMO and experience its a design flaw with the board. A short in the igniter wire is really irrelevant since the voltage shorts out at the pilot causing the spark UNLESS the ignitor wire is shorting out on one of the other leads from the control board. An easy way to prevent this is to add a inch or more of space between the igniter wire and the rest of the control board leads, but again, the board should be designed with components that can handle this.

I haven't worked with Robert-Shaw since 2000, but yikes $200 just for the board? Everyone must be doubling their money leading up to your sale.
