Electronic Ignition Water Heater Broke

[drober05]

Hi all,

I have searched the forum for an hour now and have not found the info I need.

My 1990 Excella 1000 water heater has stopped working. It is electronic ignition and normally I switch it on in the bathroom and the following happens:

1. Red light on switch goes on.
2. I hear the burner kick in on the water heater.
3. Red light on switch goes off (unless burner fails to light or goes out)


Well, the other day after having my propane tanks removed and refilled, the following occurred:

1. Red light on switch went on.
2. I heard the burner light momentarily.
3. Red light on switch went off.
4. Red light on switch went back on (burner failed to stay lit).

This happened several times and I attributed it to air in the propane lines. However, eventually the red light STOPPED going out and I no longer heard the burner kick in momentarily.


Now this is what happens when I try to turn on my water heater:

1. Red light on switch goes on.
2. No sound of burner.
3. Red light never goes off and stays on....


I've read references to diodes and lock-out switches but I don't know what these refer to. My owner's manual talks about measuring voltages at various points in the control mechanism but has no photos so is useless for me.

Any suggestions?

Thanks,

that sounds like what mine did a while back. it was a loose ground wire.

here is a thread covering it http://www.airforums.com/forum...und-12125.html

hopefully that is all that is wrong!

I have had similar problems and they were all because of the connector on the ignition control board. The connector is really cheap and it easaly corrodes. Try and pull the white control connector and clean it with contact cleaner. Check out John's idea also.
