Opened valve - nothing worked.

You need to check if there is a solenoid valve in the line down by the propane tank. If it has one that may be the cause. You can modify it as has been done by others on this forum or, it can be removed completely as they are no longer required to be legal. Also you can try to turn off the shut off valve at the tank and when turning it back on, turn it on very slowly. Hope this helps

Two things it could be.

Start by closing the vapor port and then opening it V E R Y slowly. Repeat a second time if you heard a rush of gas as you cracked open the valve. BTW, I have never heard of bleeding out the vapor or liquid lines in order to fill. Close them-- YES.

If that doesn't do it, turn off and then back on the propane detector. Listen for the solenoid valve to click open.

The only other thing in the "circuit" is the propane regulator. Not likely it when from good to bad that quickly, but I guess it could happen.

I ran into that problem recently, too, and found that there is a switch on the sensor panel that had been turned off. Turned it on and propane works just fine.

Appreciate info..

Did not turn off any sensor.. near kitchen

Will turn off then back on per Brett.. is ths powered differently? I turned off master 12v

Will it matter i already turned on gas valve and heardvthe swoosh of gas.

Do i need to bleed the lines?

The kitchen safety switch can disable the electric solenoid valve at the tank. The solenoid valve can be removed, or the internal plunger can be removed from the valve. The safety switch in the kitchen in the older coaches were hooked up to house and chassis battery banks. New detectors have only one power lead.

If you have heard the valve "click" then it might just be open now. Your tank manual valve needs to be slowly opened as mentioned. Same on BBQ tanks, as there is a safety system that reduces the flow if opened too quickly. On a BBQ the burners will lite, but just burn on low, like you are low on gas, been there, done that!

You can bled the air out of a system that has been opened, or not used. I open a stove burner and have my gas starter lite and next to the burner. Stoves seem to use lots of gas, and tend to help purge air out of the system. I had to do this on a couple of trailers to get the refer. to start as well.

Years ago during a fill up I got a bit of water that became ice quickly that stopped up the mess .Not an everyday thing but it happens . Brad Metzger

Thanks,
Dave will be looking for switch.. is it on the the device?
I have a test button and a green LED on detector.

Why would it work then stop?

Different switches on the floor detectors have been used over the years. But the detectors have a useful life, and a date label on them. Most suggest that you replace the detectors every 5 years. Detectors do their job and shut off the power to the tank solenoid, and then no gas and warning noise. My unit had a slide switch and sometimes I could get it to work again. Finally I replaced the detector and also removed the tank solenoid. Now about the only thing I can screw up is spinning open the tank main valve after refueling.

Some times I think things quit working because they can. Other times just because they are electrical items. I know nothing works after I let or see the smoke come out.

Did anyone else find it impossible to read this and NOT hear Yoda's voice? Wise Brett is!

As someone who's dealt with propane for 20 years, I agree that there is no bleeding or purging of lines that needs to happen. Stuck valve, solenoid, or other blockage is going on. First things first, as I am a cynical and jaundiced sort; have you cracked open the vapor-fill valve aka spit valve on the tank just to make sure it is indeed full? Does white vapor come out showing that yes indeedy the guy put propane in, or does clear liquid come out showing butane was stuck in there instead? This is longshot stuff but not unheard of. I would then carefully crack open a line after the regulator to make sure it's doing its job. Maybe it got bumped or otherwise disturbed during the refuel. If vapor is making its way past that, and your propane switch in the galley is on and working, listen for a hiss and smell for fuel when you turn a stovetop burner on. Start at the source and work your way back and best of luck. Last time I got to do this my search ended at the regulator...

I agree with the "Yoda" analogy!

Turned switch on-off no fire
Closed and open valve, no fire
Tapped on gas line solenoid turned on off switch -FIRE at stove, cycled hot water, heaters all have fire.

First thing coming out the sensor and in line solonide

Thanks to all!
Yoda, may the FORCE be with you!
