Do you have an LP gas detector. If you do make sure it's turned on. When it's off it will turn off the gas line.

Hi John! I would suggest you repost your question over in the "RV Systems and Appliances" section. You will get a lot more information there. A lot of people don't ever look at this Member Check-In area. Good luck!

It could be the sensor. Can't remember the correct term but it should ignite for a few seconds to get the sensor up to temp. If it does not register it assumes that it is not lit and shuts off the gas. It is a simple fix.

Some do, some don't. Ours doesn't do anything but make noise.

John,
First make sure that the gas is flowing to the pilot flame, I would suggest that you open the area up - usually there is a metal cover to the area held with a screw. Observe the flame trying to light and lots of time it is rust that has dropped down the flue . Blow that area with air. The flame should be steady and aimed at the thermocouple. If it lights and is going and not hitting the thermocouple adjust the position of the thermocouple to be in the red part of the flame. Generally takes about 30 seconds for the thermocouple to warm and keep the flame going--if the flame goes out then replace the thermocouple--easy job. Hope this helps.
