I have a 2007 Fleetwood Santa Fa with a Suburban gas only hot water heater. This week on the next to last day camping I had to switch bottles. Then my hot water heaters pilot light would stay on but the main gas burner would not ignite unless I stuck a sparkle into the burner compartment near the gas tube after considerable gas has built up. I have checked for obstructions and the tube and gas orfice are clear. This is the first time this has happened. Also, I tried to remove the anode to check it and even with Teflon tape on it I can’t budge it. I will get a six point socket tomorrow but I have a bad feeling wether I should continue to try and remove it. Any help on these two issues will be greatly appreciated. Thank you.
