Was testing all the appliances today on a new to us Aliner. When we purchased it we just asked the previous owner to light the stove as she said she didn’t use the gas at all. I know, shame on us for not testing everything before buying. So far the only thing I can light is the stove. Stove lights and flame seems adequate, not a lot of experience for comparison. Can hear sparking for heat and refrigerator but nothing lights. When trying to light the hot water I realized I didn’t smell any propane on any of the attempts to light anything (heat, refrigerator, hot water heater). Soap bubble tested the nozzle (?, orifice maybe?) on the hot water heater since it is easlity accessible and was getting no bubble to form with the dial in “pilot” and “on”. Mounted tank says it was 7/8 full but still switched to a known full tank to verify tank wasn’t empty. I may have opened the gas valve too quick the first time but closed valve and then very slowly opened valve with no change. Actually went through the slow open a couple of times. Does this sound like a bad regulator? Any ideas would be appreciated!
