Igniter does not spark/sparks intermittently

Looking at my old posts, it has been a while since I have been here. Here is the new problem.

Intermittently, one of the igniters does not spark when you turn the gas on usually it is the right front. But, it will spark when you turn on one of the other burners. All the igniters spark when I turn any of the burners on, and stop when that burner lights. I assume that that is supposed to happen.
I have replaced the igniter and cleaned them, but this has not solved the problem.

Is this a Thermador Stove Spark Ignition Igniter Switch problem? How do I tell?
Luckily, I think that all the parts I have replaced over the years still cost less than the one repair call that I did before I became adept at replacing parts on this POS.

Thanks for the help.

OK new info.

I switched the igniter switch from one burner to the other. The other burner works fine so it is not the switch. Could it be the wires wearing out? Could it be the igniter module? Should I just get rid of this POS and buy a new one - Of course I am really good at replacing parts on it now.
