Iffy stove burner ignition - Maytag FCG20510

[slantsixdan]

Howdy, all. I've been making good progress getting this range back in shape. A new bake burner ignitor solved the fluttering/stuttering and slow heating. Now I'm turning my attention to the stovetop. Burner ignition is slow and iffy. Usually fanning or blowing the burner one wants to light will eventually get it to catch.

Each burner's spark feed and ground wires are firmly connected to the underside of their burners. The ignitor snaps regularly without any snaps missing from the rhythm, no matter which burner knob is used. Sparks jump at all the burners, which are verified clean-clean-clean (one of them's brand new). But there's not a spark with each and every snap of the ignitor, and if I were to judge the spark quality based on my automotive ignition experience, I'd call it "variable leaning to poor". Sometimes there'll be a nice fat blue spark, but more often it's a spindly orange one.

Do the spark modules get weak before they get dead? Or do I need to be looking for some other problem...maybe a common point for a spark current leak to ground between the module and the burner electrodes?

Thanks in advance...

Corrosion will disrupt the ground path quite easily. Make sure everything is not just clean but free of oxidation. A scraping tool of some kind (knife, small screwdriver, etc.) will often help to dislodge some of what's blocking the spark's path.

Where, specifically, would you have me scrape?

BE the spark, where would you go?

Everything scraped, shiny bright and clean. Spark quality is better, certainly looks like there are probably enough adequate sparks to fire the burners up quickly, but ignition is still slow and iffy. Perhaps the problem is elsewhere. Any blue-sky thoughts on what generally might make a gas stove hard to light?

Now BE the fuel. Any places where it stops? Orefices can get clogged with stuff.
