water heater question

We own small TT KZ escape. This morning we woke up to no hot water after pulling into campsite yesterday ( This is first time we have taken TT out this season). Yesterday we had hot water so something happened overnight. The water heater has automatic pilot light. When I put the water heater switch to the 'on' position from inside the trailer, nothing happens...no light comes on...We have propane (meter says so and stove works). I went outside to see if pushing the black reset button would do anything. It did not need reset....My guess is somewhere, somehow, there is something going on with the electrical system which tells the pilot light to ignite...I don't see any breaker switch thrown in the main fuse panel area.....Please advise...Thank you

    It is also possible there was a little dirt or corrosion on the contacts of the fuse that got brushed off when you pulled and replaced it. 12 volts does not jump gaps/dirt/corrosion like 120 volts does. Thus it doesn't take much to break a 12 volt circuit.

    so I used my fingers and wiggled a fuse out and put it back in and now the water heater is back in operation !.....I guess it somehow got loose from the drive and then maybe when we walked around at night it loosed further.....? Seems like I am in good shape now....I definitely appreciate the guidance


    Who knows - and you did say you had it stored for awhile, perhaps some corrosion had built up on the connection... Glad you are up and running. Happy Camping!

    Often the door to the 12v fuse box will have a fuse puller attached in one of the corners. It is just a plastic "tweezer" type of device with a couple of prongs to help hold the fuse as you pull it. Some of those 12v fuses are quite tenacious and don't like being pulled. Kind of like wisdom teeth!:B

    thanks.....gotta run to the store and pick up some 15 amp fuses....will report back in a bit.....thanks for sure!!! I assume I don't need any tool except for my two fingers ?


    Haha - that depends on your fingers. :) A small pair of needle nose pliers can come in handy, just be gentle... Should not require lots of force.

    In these RVs anything is possible! LOL! Some of these 120v breakers are
    2-in-ones.. It looks like one breaker, but there are actually two switches/separate breakers. I can only guess that is what you have here. Or - they could really share one breaker. Seems like you need to be concerned with the 12V side of things for now. Yank those fuses one at a time and see if any have that bridge between the two blades opened up/burnt.

    The WH and MW can't share a fuse, the MW is 120 VAC and the WH uses 12 VDC controls.
