The recall interrupt's the 12vdc to the board. So that is not the problem. You've stated the ignitor is working, gas valve is on and yet no flame. Have you checked for codes on the display?.
Have you verify DC voltage to the gas valve when it is trying to ignite?

Open up the plate covering the bottom of the flue. In there is where the flame lives, and the igniter pops its spark into the gas there. It's likely that there is a bunch of flaky crud sitting there obstructing the whole process. Vacuum all that out of there and try it again.
Here's what I did. The assembly on this reefer is way different from what I've had in the past. In addition, there has been some modification due to the recalls, one being the installation of some stick-on insulation.
We're heading on a long trip, and I didn't want to worry about a fire in the motorhome, so I called the RV Doctor, a local guy who makes motorhouse calls (that's a pun). He came to the house and worked on the burner. The rust was considerable and the igniter was broken. The clicking that I hear was the spark to ground, not the burner. When he finally got the burner running it would fire and spit, fire and spit, as if there was some air on the line. He had to replace the burner. I have a fine flame and the reefer functions as it is supposed to. Most important, I was looking over his shoulder and I'm sure it was done right, so I will not have to worry about fire. Now, I can leave tomorrow in peace.
Thank you for all your suggestions, but some of it was over my head.
