power stablelizer jacks

I have a 2016 forest river vibe 224rls. my problem is one of the power stablelizers keeps tripping the breaker. It will start to go down and keep going until I let off. as soon as I let off and push again it tripps. Of course the dealer I bought it from said they have never heard of the problem. I said send me a new $5.00 breaker so I can see if the breaker is weak. they don't have one would have to order. want me to bring my trailer down 200 miles to se if 5.00 part would help, of course they would have to order and I would have to leave may trailer. great service NOT!
what I want to do is find out what size breaker it takes and just order one. reliable rv where I bought it can't tell me
camping world where I went by for part can't tell me.
