If it didn;t resetting nothing would have happened...no clicking etc. When high temp t-stat opens it shut down all operation. SO that is NOT the problem Problem is there is not enough propane in the line to water heater and no flow YET!! Need to try water heater again. Let it click click click even if it locks out. Then again.until flow is established thru line at water heater. Hint......light off all stove top burners on HIGH and let them burn a minute then try water heater while stove top burners are still on (this will place a demand on Propane Regulator and establish flow thru system.) Provided flames on burners are nice and strong/steady and blue. AND change in elevation is NOT the issue either. Try and post back Hey Old-Biscuit, Thanks so much for your FIX! We're trying to get ready for a trip & our water heater wouldn't light either. I tried cleaning the gas orifice, adjusting the burner air intake, etc. etc. I was planning on starting to clean all the electrodes 1st thing in the morning, or call the guy who used to work on our rig, or (God forbid) look for a mobile RV service guy..... then I remembered RV Net & found your post. Perfect! Turned on all 3 burners on cooktop, clicked & clicked the dickens out of the electrodes trying to light off the gas flow (the flame, when I saw it 'trying,' but not catching earlier was a nice clean blue) and finally it caught - hooray! I don't think I was gonna sleep, but, thanks to you, I'm a happy camper. Hope I can return the favor someday. All the best, elkhair aka BillRe: Costco GC2 specIn answer to "Are the Costco GC2's any good?" I bought 4 of them (yup, the 62lb, 224Ahr -not 208 - basically the same spec as Trojan) in April 2010. Because of a very tight area for the batteries, I had to make a custom 4-battery rack & beef up the sheet metal floor to handle the 250lb+ load. I wired them series-parallel. They are still cranking out the 13.9 to 14.4vdc they provided in 2010. I installed the watering system that feeds all 4 with one distilled water 'bayonet' connection. At approximately $70 each (vs. $125 for Trojans doing the same job) I've got my money's worth & then some. I do a lot of boon-docking, so I really use the 12 volt system. I have noticed the change from the Costco GC-2 to Interstate. For any trivia geeks; interest: upon much research before I bought them, I found they were manufactured under Johnson Controls. All the best, elkhair aka Bill :)
