Stove won’t light!

[DaveG]

We have a 2016 Sprinter Campfire with a stove that won’t light! We replaced the regulator. Stove and oven will light when the furnace runs so we know tanks have propane in them but after the furnace shuts off the stove will eventually go out again How can this be fixed? Or anyone know what causing this? Thanks

Which regulator did you replace, the main one or the stove?

Do you have a manometer?

Stange, a low flow or pressure problem would act opposite of the way you describe.

This is going to require some serious looking at, and as stated, a manometer.

I agree, this is a "propane supply issue". It's time for a manometer.

That said, if you've changed out the automatic regulator (at the bottles), and the same condition exists, then it's probably not the regulator. Have you "changed over the bottles" to feed from the other propane tank? There is a "flow control device in the bottle, another one is the "tank to regulator hose" plus the flow device in the regulator.

You might want to do a simple "change the regulator to feed from the other propane tank, just to rule out the tank/supply line issue before getting with a "propane repair expert" at the dealership.

You said the burners won’t light. Is this with the spark ignitor knob? Does the burner light with a match? If the problem is with the ignitor, lift the top of the stove and check that the wire is connected to the ignitor. We also find that sometimes we have to let the gas flow more than a couple seconds before it will light.

A manometer in the motorcycle world is a set of gauges; usually four that measure vacuum when attached to the carb bodies. These are used to synchronize carburetors. A few years ago, a manometer would have mercury in each of the four tubes to measure specific gravity (or something like that) of each of the cylinders for synchronization. The industry moved away from mercury due to environmental impact laws and the new gauges don't use mercury. How does a propane manometer work and where does one place it when doing the testing. Assume it is only to test how much the propane flow is?

Manometer use in RV is a pressure gauge that measures in inches of water column. It can be attached at any point in the LP system where there is a fitting. It is used to test for leaks in the system so it best attached at an “end”. One excellent spot is the burner on the stove. Remove the burner and using the “bell” on the hose, attach the meter. Turn the burner on and note the pressure. Then leaving the burner on, turn the LP off at the cylinders. Bleed the pressure down, and then by RVIA standards a ZERO drop in 3 minutes means the system is intact and has no leaks.

It’s also used to measure how much pressure there is at appliances like the refer for troubleshooting. There is a plug you can remove at the gas valve. Then install the special fitting that comes with the manometer, hook up the hose and turn on the fridge on LP. The gauge will show you how much pressure is present. You can turn on the furnace or stove and verify minimum pressures are still present.

Hope this gives you an idea of what we use a Mano for in the RV industry.

A gas manometer is simply a rubber hose with a brass connection on one end and a dial gauge on the other that is calibrated for inches of water column. Price is around $50 +/- depending on brand/quality. Professional grade more, shade tree mechanic less. But before you go too far, know your limits. Gas is not something to experiment with, unless you know what you are doing it might best be left to a professional.

Time for a service call.

Here you go, a DIY manometer and tutorial on use;

For motorcycle use I like my Twinmax;

Thanks. Will keep the propane manometer in mind if I believe one is needed. I replaced the regulator after buying the camper (it is a 2002 and not comfy with old gas related stuff) and have never really had any issue. Thanks to all who provided some education.
