DC Breaker

Where is the DC Breaker on my 2023 3123RL Montana?

Welcome to the forum

DC breaker for what? What is the issue you’re having?

[Kkoconnor]

All of the lights, fridge, and heater aren’t wrkg. All my other switches are. I am an amateur and not a fix it person but thought maybe I tripped the DC breaker. I found breakers in the Gigi box but don’t know how to do anything

The "breakers" in the giggy box should be self resetting circuit breakers. You can test them with a meter or a test light. You should have 12VDC on both sides, if not it has failed or is not self resetting and has a reset button on the side.
Testing using either method, you hook the negative side to a ground and the positive side to the posts of the circuit breaker.

A few question, first, on the Giggy box, is the battery switch in the on position? Are you plugged into shore power? Last question, what was the circumstance before this 12v dc power loss? Was the 12v DC OK one day and not the next, or has the camper been setting unused for a couple of weeks and now you don't have 12v dc, or ???

Well, there is an ac breaker that supplies power to the converter that may be tripped. The converter converters the 120 volts AC power to 12 volt DC power. It is usually located near the breaker panel.

On my breaker box, the converter 120VAC breaker is marked CON. To reset a circuit breaker, push ALL THE WAY OFF then all the way ON till it clicks into place. Often a circuit breaker will no appear tripped but the breaker will be a bit soft/spongy but mostly in the ON position. Hope that made sense.

On the Montana's, they usually install the breakers on the wall behind the batteries. The breakers are self resetting, so surprised it did not. The breakers will look like either of these photos, and the smaller one may have a red plastic insulating cover on it. The last photo shows what we have in our Montana. The black 80 amp breaker used to be the same as the other small breaker, but I replaced it with the Lippert recommended breaker. I suspect you already have an 80 amp breaker because Montana finally started installing them.
