Went camping this weekend, but we ran out of hot water for showers, which has not happened before. We normally run the Hot water on electric mode which has always been fine. Now I can't get the hot water heater to work on either electric or gas.
I think it might be the Thermal cutoff. Has anybody out there had to replace it? Where do I get one and is it a big deal to replace?
By the way it is an Atwood heater.
Thanks

It sounds like time to check your fuses and circuit breakers. Your heater probably requires both 12 volts and 120 volts. The 12 volts for control and ignition. The 120 volts for heating. On top of this it needs propame to operate in gas mode.

If it is a fairly new one, there is a thermal fuse in line, very visable and easy to by pass to check if this your problem. It looks like an automotive fuse.

I’ve had a couple issues with my Atwood, one that is still bothersome is that it takes about 4-6 retries for the gas to stay running. Starts right up after a short shutoff.
I’ve cleaned all connections and contacts on the PCB and have voltage where needed. My last problem was on the last day of my most recent trip was the lose of hot water, gas and electric. I lucked out and found that a recently installed thermostat was defective. I replaced both of them. SUGGESTION: when removing wire from thermostats put some pressure between the wire connectors as mine was extremely tight and when attempting to pull the wires off I pulled the entire thermostat out.

It was the thermal cutoff. Replaced it today which was very easy and got hot water on both gas and electric. I also cleaned the combustion tube which Atwood recommended when replacing the thermal cutoff. Whole job was 15 minutes.
Thanks for the responses
