A good freind of mine has a 98 model and the water heater switch is on the panel in the hallway. It's about chest high and on the right side. It is gas only and the switch turns it on and it ignights automaticly. Also check all the connections on the water heater heater by removing them and re installing them a couple of times. they do get coroded. I had to replace this switch on there RV two years ago.

My 1997 Dolphin M.H. Water tank would only run on propane but I installed a hot stick just so I would not have to use my propane when we were hooked up in a camp ground.
The frig runs the same way.
Just a thought.

I found the switch. I checked the fuse on the t-stat wire and did pull the plug on the circuit board. Nothing yet. When I turn the switch on, it does light up along with a red dot just to the left of it, but it just stays lit and the tank heater does not ignite. Sigh.

Assuming you have a DSI (Direct Spark Ignition) water heater when the switch inside in turned on you should hear the clicking of the igniter sparking. If the igniter is working you should also hear the gas valve open and the burner light. If no flame is sensed the burner will be locked out for safety, that's the reason the the small red light next to the switch stays on. If you don't hear the igniter working it could be out of adjustment or the ignition control could be bad.

It is a DSI unit. Propane only. I'm figuring that the electrical box with the wire in it behind the tank is if a tank were installed with the optional electric heating element.

I do not hear any clicking. I tried cleaning all the contacts. I even removed the fused link on the one wire to see if it was bad. Nothing.

Could be a bad 2 amp fuse on the circuit board or the ignitor is out of adjustment or the ignition module is bad or the main circuit board is bad or the high temperature safety stat is open. You can test the safety stat for continuity with a VOM meter. Check if the ignition module is getting power from the main control board. I attached the manual if you don't have it.

As I said chech all conections on water heater. Corosion is the bigest problem. In the Manual the first thing it said was low voltage and that can be caused by bad connections.

I finally said "uncle" on the water tank and it's at the RV service place near me. I've only got three weeks until by month long trip, and I have other things to get done. I'll let everyone know what the final diagnosis is.

Thanks for the info offer. I may take you up on it. And that circuit board, $360 !?!?!?!?!? Just for that!?!?!?!? If I'd known it was going to be that much, I would have just replaced the whole stupid tank with a 10 gallon for the $425 I could have bought it for on ebay. GGRRRR.

Everything's working great. No need for a hot water tank here in Vegas. 104 yesterday and the same today.
