Gas Stove Burner Igniters Won't Fire

[interstateflyer]

The gas stove burner igniters in my 2017 25FB won't fire. Does anyone have idea about how to troubleshoot the issue?

Hi

I believe you will find a 12V circuit that goes into the stove. I'd start by checking it with a multimeter.

Begin by lifting your stove top up and looking below to make sure the wires that connect the ignitor to the burners are connected. You may also be able to tell from above if you see a small spark at each burner when you activate the rotating ignitor knob. Also, check the rotator knob to make sure it's turning the ignitor. The plastic tab that does the rotation can break off. Then you need a new knob.

Hi

A lot of the exact details vary depending on exactly which version of the stove you happen to have. The basic check the ignitors / check the switch(es) / check power in still apply.

Not necessarily. My stove uses piezoelectric ignition, just like high-end butane lighters, only bigger. Press on a PZT (Lead Zirconate Titanate) or quartz crystal in just the tight way, and it makes a brief current that will cause a spark. No 12v circuit from the batteries at all. These igniters can quit working if the crystal inside develops cracks.

I don't even bother with the piezoelectric ignition on my stove burners anymore. I just light them with a long-handled butane lighter for barbecue grills. More reliable. Light the lighter first, then turn on the propane, and whoosh, lights every time.

Thanks everyone for your suggestions. I report back next week when we have the to dig into the problem.

My stovetop ignitor would not activate nor would the oven light work. Took it to Airstream of South Carolina and the tech, after an hour of troubleshooting, determined that unless the galley lights were turned on via the Firefly the oven llght and ignitor did not get any current. ???

nowhere at all in Owners Manual is this mentioned, and so wonder what logical process AS used to wire the system in this manner??

Thanks to Matt at John's RV in Lexington SC for bird dogging this problem.

Not the answer you seek, but I keep a gas wand in the cabinet above the stove. Maybe mine will work, but I find it's just as easy with the gas match $4 everywhere.
If it's important, raise the stovetop and push the igniter.
It should throw a small spark at each burner. I think we don't get enough gas get to the burner before pushing the button. You need the correct amount of gas/air for stoichiometric combustion.
(okay, I confess, I had to look up the term.)

We also have a 2018 30' Classic. The only thing that has to be turned on to make the ignitors and oven light operate, whether on shore or battery power, is the red battery disconnect switch. The galley lights have nothing to do with it, or at least they shouldn't.

Hi

That's what's known as a wiring error. They do indeed happen in RV's and in great big commercial airliners ( yikes !!!). Get it fixed while you are still under warranty.
