Slide out circuit breaker trips

Yes, that is a common problem. The auto reset circuit breaker begins to get weak and start heating, tripping, cooling, resetting, heating, and so on. Good news it that they are inexpensive and easy to replace. Available at RV parts stores and many auto parts stores. Amp rating will be listed on the side.

If you are not already a member of the Montana Owners Club forum go there for all things Montana.

Also make sure all the connections are tight and corrosion free. A bad connection or low battery voltage may cause the breaker to overheat and trip.

Have you cleaned and lubed the slide? It could be just pulling hard and overloading the circuit breaker.

Is the breaker located in the main panel box inside the camper or inside the front compartment where the hydraulic pump is located?

In the front compartment back wall near the slide hydraulic pump, at least on mine. My '07 Montana has two, one for the slides and one for every thing else. Look for one that has a large wire going to the pump assembly.

Remove the positive cable from the battery, remove both wires from the breaker, remove old breaker and check sides for amp rating. Probably a 50 amp breaker. When installing new one it will probably have one brass colored terminal and one silver colored one. Wire from battery to brass, wire from pump to silver.

Thanks for all the input. Hopefully I can take it from here and repair the problem with the slides

Same thing happened on our 2009 Montana. Get American made breakers to replace the Chinese breakers that came with the RV. On our unit there are two identical 50 amp breakers wired in series. Mounted on the back wall of the front storage area just above the battery and below the slide hydraulic pump.

Why would you want the circuit breakers wired in series?

Where were your breakers located. Don't seem to be able to locate the breakers on the 2011 Montana
