A problem has developed in our water heater, and I'm debating the best course to take.
We have an Atwood LP/Electric 6-gallon water heater, model number GC6AA-9E. A few days ago the electric 'side' of the unit stopped heating. It happened all at once, not a slow degradation of the heating capability. The LP heating continues to work well.
Trouble shooting so far:
- Circuit breaker reset
- Cleaned some electrical connections in the outside heater access
- Drain and flush hot water tank
The unit does not have an anode, so I don't have replacing that as a possibility.
The unit appears to have a single thermostat, and since the LP heater is working, that should not be a cause. Having said that, I have read that older Atwood units have two thermostats (LP and Electrical each being unique). I don 't know where 'older' begins, or how the unit would look if it had two thermostats. Our coach is a 2001 model, and this looks like the original unit.
The next step I have in mind is replacing the heating element. The element is on the back side of the tank (inside of the coach). Replacing the element will require either partially disassembling some drawer mounting frames for access, or removing the heater from the outside.
Here are my questions:
1) Is there any other trouble-shooting I should perform before tackling to the electrode?
2) Is it fairly easy to pull the unit (and unhook/reconnect all the LP/water/electrical connections), or
3) Should I try to change the electrode with the tank in place, if possible?
All suggestions/thoughts appreciated!
