Changing high/low thermostat switches

I have been troubleshooting my inop water heater for awhile, neither propane nor electric work. Opened the high/low thermostat and the switches are fried. Is this something you can change yourself? Where do you get the parts?

First you have to tell us what you have?
What year and model trailer as well as what brand and model hot water heater.

If the high and low limit switches are fried you need to find out how come? These are just temp switches and open when temp exceeds a set high. They are also resettable in most cases.

Please give a little more details and maybe we can help.
A picture would be great.

Does yours look like this picture?

Here is aplace you can see what the thermostats look like on Ebay

Yes, I have a suburban SW10DE In my cedar creek, not as nice as the new one you show. I have no idea why they fried. Which is the black and which is the red. The black is fried and the red is broke

These photos and wiring diagrams might help you.

They are REAL easy to change (as long as the power if off). 2 wires each and one nut and washer. The two black wires are AC side and the 2 red wires are DC/Propane side.

NOTE: They are TWO DIFFERENT thermostats. The AC and DC are not identical.

You can also buy them on eBay.

Also I am curious how both failed... Did you run the system without water in it?

Herk, this is great info. I do not have exactly how they fried but I suspect it was when I let my son stay in the trailer without me over the winter. Go figure that! I hope this fixes my long standing issue.
