Atwood water heater electric not working

[miner89r]

I'm having an issue with my Atwood water heater (GC6AA-10E). It was working fine the night before but this morning I woke up and the hot water was just barely warm. When I switched from electric over to propane it was working fine again. I got to the back of the water heater and verified that I have 120V at the terminals on the back of the heater element. I used a clamp meter and measured about 12.5 amps thru the heater element when the electric WH switch is flipped on. I also measured the resistance of the heater element and got 10.4 ohms which seems ok. Could the heater element still be bad? It is possible that I ran the electric WH with an empty tank when I first picked up the TT and didn't know what I was doing but that would have been a month ago and it's been working fine until this morning.

I verified that the bypass valve is closed and the unit is working fine as long as it is on propane mode.

Your ECO/Hi-Limit switch is tripped. See page 12 of the Atwood WH Service Manual below. Be cautious, make sure you turn off the breaker for the heating element before resetting the ECO/Hi-Limit switch. You have to remove the cover and the connections will be exposed.

Well the problem seems to have resolved itself as our water is nice and hot again this morning. I guess cutting the power on and off so many times during trouble shooting caused something to reset. Thanks for the manual. That will be very useful for trouble shooting the next time sometime goes wrong.

Good to know something worked itself out. Or as my grandpa used to say maybe "you aint holding your tongue right".
