LPG System Question

Yahoo Message Number: 23297
After having the LPG system shutoff at both the tank and the LPG detector for the winter, the gas appliances (refrigerator, cooktop and hot water heater) will not fire. I reset the detector several times and it seems to be operating (green light blinking). Tank is full, tried it both with shore power plugged in and unplugged, however house batteries are weak (but that is another issue). Connections at solenoid look tight. Has anyone had this issue and how was it resolved?

Thanks.

I had this problem once after letting the coach sit for a couple of month and it can take a bit of time to get the gas going. I guess air can get in the lines. Try this.
The cooktop uses the most gas so use it to get the lines filled, once the cooktop starts and continues to burn you should have no problem with the frig and water heater. It may take a few minutes to get the cooktop to where it will stay on. I would think your house batteries have enough juice to fire the cooktop igniter and you will have to hold it down for a long time.

If you turn on the cookstove past the igniter position then you can hear "the gas sound" if it's getting gas. Then suspect air in the lines. If no "gas sound", then gas is probably not getting to the units.

If you hear the "gas sound" then I would open the windows, turn on the fans, etc. and turn on the burner or burners and purge the air from the lines. Once I get the burners going, I let them burn for a minute or so. I then turn on the other appliances and they should lite.

Chuck-It sounds like you need to purge the air from your gas lines. Turn on a burner on the cooktop and hold a match to it until you get it to light. This may take several attempts. Be sure you have adequate ventilation and do not leave a burner unattended! Macke 2003 Magna #6277 in Ocean Shores, WA

>Hi All,
Thank you for the quick assistance! Unfortunately, it appears that although the green light is flashing and the LP tank is full, we are not getting LP to the appliances (no hissing sound at cook top). Any other suggestions?

Reset the propane detector switch (turn off, then back on). This happened to us and that's what I did and it worked. If the propane detector is faulty, you won't get any propane. It's a safety thing.
Maybe resetting it will do the trick. Or maybe you need a new detector. Good luck!

I have heard that sometimes ice crystals caused by water vapor in the propane can lodge in the regulator. The cure is to pour warm water over the regulator as well as the valve to open and close the flow to the MH.
When doing this have another person open a burner on the cook stove and have a match ready to light the propane if/when it starts to flow. Have not done this myself but have heard the procedure works.
Good luck.

Turn on a stove burner and wait until it will light and the rest of the equipment will then function.

There is probably an electric valve in the propane line (mine is right next to the tank) which is supposed to shut off the propane if the propane detector goes off. Might want to check this switch.

I had a problem very similar to yours a couple of years ago. The problem was the wire going from the leak detector to the solenoid on the gas line (very close to where the gas line exits the tank, look for a valve with two wires going to it at the tank)was shorted.

In our case the wire routing from the LPG tank goes across the top of the diesel fuel tank. Unfortunately, in cooler weather field mice from one of the parks we were in had found that it was comfortable to sit on the top of the fuel tank and nibble on the wire insulation. They had chewed into the insulation exposing the wire and it was shorting on the corner of the diesel fuel tank bracket (also not a good thing).

To my surprise in the past couple of years I have found 3 other RV'ers in campgrounds that have had similar (or even worse) problems with mice chewing on wires. I now have two large rodent alarms that set off strobe lights and ultrasonic sounds to chase the mice away if I happen to be in a park where they may exist. Have has no further problems.

This may not be your problem but I would certainly check the continuity of the wires from the leak detector to the solenoid valve near the tank. If for any reason it is broken or loose it would cause the problem you describe. The way the leak protector protects you is by opening the circuit in the wire to the solenoid valve and shutting off the valve.
