Water Heater will not stay lit on gas
Atwood 6 gal gas/electric in 2005 Classic. The water heater works just fine on electric, but when we tried to run it on gas it would only light for a few seconds and then shut off. The switch light in the bathroom does not come on at all. I have checked the switch light to make sure it wasn't burnt out, and it is fine. Removed and cleaned all of the connection, removed and checked the venturi tube, no spider problems. When the gas switch is turned on I get the gas and ignition, but only a couple or more seconds of burn time. I have made so many attempts that I am certain that the line is bled. Anybody experience this, and or suggestions to get the water heater working with gas. I have read about a "flame sensor", but can't seem to find it, any help with that would also be appreciated.
