He recommended the Dinosaur Electronics igniter board and told me that he had never had to make a claim on their guarantee. They work. Great company right here on the coast of Oregon. https://www.dinosaurelectronics.com/

Most of us with any "long time exposure" to RV propane appliance problems have used Dinosaur Electronics control boards for years. My first exposure to them was in the early 90's and I've been a fan since then...

That said, if the water heater, furnace or refrigerator is still in warranty, then the manufacturer will require (in every case I've seen) that OEM parts must be used. Once the warranty expires, using Dinosaur Electronics products should be, for most people, a "no brainer"... But during warranty, not allowed if a warranty claim is processed.

What John said. If it were me I'd by the dinosaur board and keep it on hand for when it DOES fail again. That way you can replace it and not have your trip interrupted, then have it replaced under warranty when you get back.

The only problem I've ever had with my 12 year-old Suburban furnace is debris in the orifice. I've had it cleared 3 times. How it gets there, I don't know.
On one of the service calls when furnace didn't fire up, the guy replaced my board with a Dinosaur board. Still didn't work so then he found a grain of debris in the orifice. He cleared it and it fired up.
Meanwhile, the Dinosaur board did not consistently trigger my furnace. I had to manually run the thermostat lever up and down to get heater to fire up. Not convenient at 2am when furnace failed to start on its own.
A year later, I had the same tech replace the Dinosaur with a new Suburban board and haven't had a problem since. I assume he sent the Dinosaur board back.
In the meantime, I've had to have the orifice cleared 2 more times. Each time I've seen the evidence myself...a grain of something 1/2 the size of a pinhead.

That's always the first thing I look at when furnace doesn't start.

Good luck.

Check the sail with for construction debris from manufacture. There is a on/off switch on the furnace, I had to access mine from the outside panel. There should also be a light that blinks for different furnace codes and a code info sticker on the furnace outside. My 2019 315rls did the same thing and it was a mucked up sail switch. Good luck
