Possible dead breaker

We have a 2005 19' Bambi, and just got it back from the shop to get a sway control ball put on and break/axle check on it. It's been gone about 2 weeks and when I got it back home and plugged in, I noticed the fridge wasn't working. Breakers were all on, I went and ahead and flipped them all, checked fuses, but then I tried to push the "test" button on the GFCI 20 amp breaker and it would not trip. Then I noticed that its seems that circuit is dead, no power to vent fan, light, tank monitoring, water pump. The circuit it labeled "GFI-bath-refer-galley-outside" so it seems possible its a bad breaker? It switches on and off, but does not trip when the test button is pushed. I've seen breakers and GFCI receptacles go bad before, so I am thinking this must be it. I have an electrician coming Monday, as I'm not really comfortable replacing it myself. Any other thoughts on possible issues? Thanks!

Can you confirm that your trailers 12VDC systems are also working?

The fridge needs 12VDC as the control system power.

As an electrician one thing I always tell people is when you reset a breaker that has tripped you must first force the handle hard to "OFF", if you don't do this it won't latch "ON"

Hi

Yes, it's perfectly possible the breaker broke. It happens. Let the pro sort it out on Monday.

I was actually a home inspector for 5 years, so I have some experience throwing breakers (and homeowner for many more on an old house) so, yeah itís definitely been hard off and on.

Sounds good. I can't tell you how many service calls we had where we tried to explain this over the phone and the customer insisted they did it, then we'd get there and reset it in two seconds.

Happened to me. It was a weak GFI breaker in the 2016 AI, always popping after about five minutes of service. Finally, I pulled it out, took it to the hardware store, and got a new one. Been working just fine since.

I had my refrigerator stop working after about a year and half, and it turned out to be a bad circuit breaker.

Where is the power? Did you test at the breaker terminal screw? If no power there check bus, bus jumper. If there is power at breaker terminal screw work the other direction, most likely came apart in a receptacle. Does the new GFCI breaker trip on test? If not, it is not receiving power, check bus jumper.
Note on edit:
It's a bit confusing that you say fridge and vent fan, are you talking about the 120 volt power or the 12 volt power?

I don't mean to offend you but the fact that you replaced a $50 breaker and it wasn't the problem suggests you are working by trial and error which is not a good way to do electrical troubleshooting. If you do not have the equipment and knowledge to follow the power I suggest you wait for the electrician.
If it's your 12 volt did you check not only the 12 volt fuses but the 12 volt circuit breakers?

Ah, vent fan/light? Those are 12 volt, aren't they?

Have to agree that you might want to get yourself a certified RV type to work on your rig for you.

You quite possibly have a 12 volt breaker that needs to be reset. Check this first!! No 12 volt, fridge no work!

Well it wasn’t a breaker, but it was a fuse! I found the diagram and pulled that specific fuse and sure enough it’s blown. I had checked them by flashlight, but hadn’t pulled them all (FYI, in this model it’s the pink wire 20amp fuse that controls galley, monitoring system, fridge and range vent/light). The breaker needed to be replaced anyway as it was not tripping with the test button, so it’s not money wasted. Now I’ll go buy a few fuses! Thanks for the help and the emphasis on the 12 volt system.

Great news that you found the culprit! It's not a shabby idea to get yourself a small box of assorted fuses from a big box store or the hardware. For starters, they're cheaper that way, and you never know when you just might need one.
