Stove & Water Heater Won't Light...

[krloo]

2016 Jayco Jay Flight - the stove & water heater won't light unless the furnace is running. As soon as the furnace is done cycling, I lose flame. Both propane tanks are full. Thoughts?

Could be your regulator on or near the tank. They do go bad. Try giving a tap with a wrench and see if it helps. If it does, go out and buy a new one. If it doesn't and no one else has a better fix go out and buy a new one.


Check for bad pipes, collapsed or pinched. Leaks anywhere. Not likely to be the problem but good time to do it. Also, turn off propane at tank. Run furnace to exhaust all pressure in lines. Then do a reset by VERY slowly turning on tank valve to SLOWLY refill lines. Then try lighting stove, etc.

The stove is easier to troubleshoot.

Just so we're clear. With the furnace on there is gas to the stove. With the furnace off there isn't gas to the stove? Do you have a rear kitchen? I'm trying to determine in what order they plumbed in your gas lines. For example on my rig the first appliance from the tanks is the stove. I need to light the stove to draw in the gas then my fridge and furnace downstream will reliably ignite. But, that is only the first time after closing and reopening the valve. Your issue seems different.

My first thought is it is working when the furnace is on, so how could it be malfunctioning when the furnace stops. Now I';m wondering if you are suggesting that it needs a stronger pull from a bigger energy user? That's kind of interesting. Somehow the furnace sucks harder and can get gas through the regulator.

I too think the regulator may be the culprit. The furnace is a pretty big consumer so the issue may occur when the gas flow is too low. Have you had all stove burners and oven on (if you have one)?

Exact same problem here did you find a fix?

This thread is 4 years old and the original poster was a "one and done" poster that didn't even bother replying to those looking to help.

If you have the exact same problem, what have you done to try to resolve it? Have you changed the regulator as suggested above? That would be a good start.

Just changed the stove regulater since i thought it was just a stove issue, but turns out its water heater aswell. Ill give the regulator a try when i have a chance and post if solved issue thanks

Perfect. We'll wait to hear from you. Good luck.

Problem fixed. Swapped out regulator by the propane tanks. Everything is working thanks appreciate the help!

Nice work, and thanks for reporting back with the fix. I'm glad to hear you solved the issue.
