The Slides on our RV pause when they move in and out. We lived with the issue because I could not find the cause. Pump had plenty of fluid and ran ok. I thought it was just old and had some kind of over pressure switch built into it. I finally found the real cause on this forum so I wanted to share pictures of the installed fix.
The issue was a weak automatic breaker. It would trip then reset after a few seconds and slides would move again for 5 seconds then stop.
The breaker for the hydraulic pump is located on the back wall above the battery and below the pump.
It's a 50 amp breaker but I read that the circuit for the pump is good up to 100 amps and that the pump can pull up to 80amps. Hence the breaker popping off.
The solution is to replace the single 50amp with 2x 40 amp breakers.
These can be bought for about $5 each at any auto parts store. The local autozone didn't keep them in stock, but ordered them and they arrived the next day. Oh, I also had to buy 4 nuts. I used the nylon locking kind to keep things from rattling lose.
I mouned the two new breakers next to the old one.
(I didn't have the square head bit to remove the old one.)
Next I used two copper pipe straps to bridge the breaker poles. One on each side. Wrapped in electrical tape.
Last I mounted the wire going to the pump to the top left. (Aux side of breaker). And mounted the battery to the copper pole side of breaker. (Bat side of breaker).
After that, all three slides move in and out seamlessly.
I'm now a hero to the wife, since she was the one stuck pressing/waiting/pressing/waiting before.
Happy RVing.
