From what you are describing I would suspect the ignitor system. The electrodes have to be located properly with the proper gap for the burner to light correctly, sounds like you have replaced most of the other parts although sometimes you get infant mortality.

If it were an issue with the power vent, the burner would not get the chance to light so the reset button would not get the chance to trip.

My guess anyway.

Page 5 of this manual shows the measurements for this particular model burner. It's important that they measure this with a gage or a ruler, a lot of guys just eyeball it......... I wouldn't mess with this unless you know how to open the burner up, but I wouldn't hesitate to look over the guy's shoulder and ask questions.
