Flagstaff Microlight water heater not working

kathomas · 05-25-2012, 11:03 AM

Hi we are campling right now. We have a flagstaff microlight 24 ft travel trailer. We are using propane. The water heater was on but then shut off and we can't restart it. The fuses look good. Read the manual but could find no help there. It won't even try to relight when we turn the on/off switch in the trailer off and then wait and turn on again. We get nothing. Is there a reset button somewhere we don"t know about? Any help is appreciated.

First I would make sure you are not out of porpane. Can you light up your stove?

High limit reset buttons under the rubber disks outside under the metal cover. There are two there.
Press both.
If one clicks; you had an overtemp.

Yes we have propane. The stove works. If it is an over temp, is that bad? Any other ideas if that doesn't work. I am heading back up to the camp site in about an hour

Here is a schematic that can help you troubleshoot.

Try running it on electric, if so equipped.

If you have a dual water heater AC and DC/Propane; remember they are two separate systems that do not have common components.

Even the high limit switch is side by side with the other one.

In this photo of the two switches (they live behind the rubber reset button circles) you can see the one on the left has burned out (the wire that connects the two is missing on the left one.

I"m not sure if ours runs on electric also. I believe ours just runs on propane. I can"t even remember seeing the rubber gasket, but it must be there. Hope it is

Look at the photo in post #5 the black rubber area is where the high limit reset buttons are.

You can also try removing power completely (by turning off the switch and waiting about a minute) to reset the control board.

Is there a "fault" light by the switch? If so is it on? On my trailer, even with the switch on the burner doesn't come on unless the water has cooled enough for it to need heated again.

I think the fault light will come on if the burner tries to light and doesn't for some reason. Mine comes on when I fist turn on the switch, but goes off when the water heater lights.

Another idea of something to check.
