Hi all, Brand new to RVing and would like to have some help. My husband and I just completed out "maiden voyage" or "shake down" cruise in our 'new to us' travel trailer. Everything seems to work perfectly except our water heater. Since neither of us is mechanicaly inclined I thought maybe I could get some help here. The water heater is propane, we light the pilot, it stays lit, we turn the knob to on and it goes on with a 'swoosh' and stays on for about 1 to 2 minutes. Then it turns off. I know it is not long enough to heat the water and no hot water (or even warm) comes from the faucet. Do you think I have a problem with the thermocoupler or anode or WHAT. Thanks for taking any time to help us with this.
