We have 2006 Storm newbees. Electronic ignition sometimes turns water heater on. Do we turn off electronic switch until next time we want hot water? That doesn't work. Or, should the heater continue to cycle on and off?

We can't find any other switch for electric on/off. Replaced the thermal cutoff and sometimes playing with it ignites the burner. Very sporadic.

Thanks for any help you can give. We are far from our service center where we purchased it .

Under normal operations it cycles on/off by itself depending on water temp in the heater. Some people leave the switch off until the need hot water, but it does take several minutes to heat up.

It sounds like you have some spiders or bugs in the burner/ignitor area causing the trouble. They may also be in that air tube that adjust air intake to get a nice blue flame. Check and clean out all those areas. It could also be a loose bad connection on any of the control wires. I would pull all those connections to check them and reconnect. 4 of those connections will be to the E.C.O. and T'Stat, which are your on and off thermostats. If bad, these can be bought cheap at any RV shop. All of this is accessed on the outside of the coach and your problem lies there some place.

The ECO is normally closed and should remain so unless the heater severely overheats. It's function is for emergencies only, and the adjacent regular thermostat normally keeps the temperature in the right range.

If you wiggle the wires to the ECO and the heater lights up, you have a bad (probably corroded) wire connection somewhere. It is not likely to be the ECO itself, though I guess that is conceivable.

What brand and model of water heater is it? Probably an Atwood but the model number would help to provide better advice. The model number, e.g. GC6AA, should be on a sticker inside the outer access door to the heater.

It is an Attwood, # G6A8EWIN. Thanks for your help.

Check connection on brown wire going from coach to the t'stat. Then check the one leaving t'stat going to control board/box..... then test. If water is cold, bypass the t'stat with a jumper wire. If it fires up, the t'stat is bad. If nothing yet, pull the connector on the control board, check for corrosion, clean and replace it. Then check both the connections on the ECO thermal switch. This should get you going, if not get back with your results. You could still have a bad board, ECO or gas valve.
