My travel trailer has a gas only hot water heater. Would this be (I don't know if I am wording this correctly) connected to a circuit breaker or a fuse?

If it’s electronic ignition, it will be hooked to 12v power and be fused. Pilot type use no power.

A propane only water heater would not have a 15 amp fuse or breaker.
If it is a "self ignite" type heater it would draw less than 1 amp and would be fused. If it is a "pilot light" type heater it would not have a fuse or breaker.

Recently my A/C would not come on, my water pump would not come on, the hot water switch for gas would not work and the switch used to open and close the slide outs would not work. After checking the problem, I replaced a 15 amp fuse and it corrected all of the problems.

thermostat needs 12VDC, hot water heater with DSI needs 12V DC, fridge needs 12VDC even when running on 120VAC for the element,

usually fused by 10A or 15A fuse in the fusebox.

Often the slides are on a 30A 12V self resetting circuit breaker. I replace those with a 30A manual reset circuit breaker so they won't cycle on and off in the case of a real fault.

If there is a switch inside the camper to turn it on, yes, it has a fuse.
If you have to go outside to light it, no fuse.

If the switch never lights up it sounds like a blown fuse or a bad switch.

With the switch off you should have 12 volts on one side of the switch to ground. If the switch is on you should get the same voltage on both sides of the switch to ground.
