Slide Hydraulic Out is Great, In is Tempermental

I have a 2006 Montana Mountaineer 342PHT with three slides. It has an electric motor with a solenoid and hydraulic pump and hydraulic hoses going to hydraulic rams for the slide outs. When I put them out I push the button and it works great. When I put them in it stops and I have to wait 5-10 seconds to go again and this goes on for about 10 times until they are in. I replaced the solenoid but that is not it. Hydraulic reservoir is half full. Is that not enough?
Any ideas of what to check next? It always works, but always like this for the past year and I have put them in and out at least two dozen times.

    There is really nothing in them to fail except the contacts get burned and cause the overheating. Simple piece of bimetal that bends away from the contact when it gets hot and toward the contact when it cools.
    Here is a bad one.

    All good ^^^^^^^^

    As for that reservoir level......half full?

    With slides completely retracted (IN) check reservoir level........should be almost full. Add fluid only when slides are retracted (fluid added when slides are extended with overflow out of reservoir when you retract slides)

    Look on the side to see the amp rating. You can buy them at RV parts stores and many auto parts stores. Cheap and easy to replace.

    X-2 replace with one larger than what you have.

    I have two brand new batteries last September and voltage is full. I do have the circuit breakers just like that. I thought they went bad completely, not partially. They are cheap so I will replace each one of them and see if that makes the difference. Thanks for pointing that out.

    Battery! Check battery voltage before and after, check cable connections.
    Oops this is also in the wrong place.
