There are two there. The left one (as you look at the water heater from the outside) is the AC side (electric element) and the right one is the DC/Propane side of the system.
If they don't click in, then they were not popped for an overheat condition. It does NOT mean they are "good." Remove 12 volt DC power by pulling the fuse in the power center and open the water heater circuit breaker by snapping the breaker to OFF. It may be on the same circuit as the fridge.
Remove the screws holding the rubber cover and examine the right thermostat.
The thermostat's high (or low) bellows may be damaged or the fusible link between the two may have melted (see photos).

There is just one nut that holds it on. (don't drop it and lose it.)
Make sure you buy the correct one! They are not interchangeable and are "handed." The right one is DC/Propane and the left one is AC.
