American Standard Freedom 90; Burners would not ignite; 2 flash code

I have American Standard Freedom 90; year 2004;
When the power switch is on, the inducer motor would start, then igniter would start to glow. Then there is a click and when the burner is supposed to ignite- nothing happens. This sequence would repeat three times and 2 flash code would start to flash.
Gas valve has a blue and red 24V wires. I checked the red wire with the voltmeter, one prong attached to the wire and other to ground (fitting on the gas pipe). After the ignitor starts glowing, and after the click, there was a 24V burst of power for about 1 sec. Then the voltage goes to zero. That means that the gas valve is getting the signal from the control board but is not opening for gas to flow to the burners.
I ordered the replacement: Valve Gemini, model 36G22 type 209
I removed the old gas valve and the connecting short pipe. That part wasn't easy; the gas pipes were stuck so I put some DW40. Installed the new gas valve and so far it is working.

Considering the OP solved the problem, and the absence of a question mark, I'd conclude that there is no question and that the OP is trying to be helpful to anyone searching this forum with a similar problem in the future.

He sounded justifiably happy with his diagnostics and solution. And where else can a DIYer get to crow with a few pecks of a finger.
