Hello all, I am new to this and look forward to learning from you all. We have had our 5th wheel for a few years now and have loved every minute of it. But now there something not making us very happy. After winterizing it the kitchen slides stopped working. One is about 1/8 the way out and the other is about 1/4 the way out. When i called the dealership and spoke with a tech he said it sounded like the Trombetta Solenoid. So I went and bought one, replaced it and nothing. I can't even find where I could even manually move it in. I am sure I may be missing some details so please ask or give any suggestions, at this point i am open to anything that may work. Thanks in advance.

The dealership is the wrong place to call. Lippert is who you want to talk to. They have a great support organization and will help you figure out what is wrong.
Lippert has an App which provides lots of good information for DIYers.

It helps if you describe, in more detail, the symptoms of your problem. Apparently the slides are partially extended.

I assume you have hydraulic slides that are inop? I say that because the dealer had you change the Trombetta valve which is only used by a hydraulic system.

When you depress the room switch, what do you hear? Does the pump run? Is there a click in the battery area?

What voltage is present? Do you have shore power. Is there 12V to the self-resetting circuit breakers (do a Search here for them) all the way to the pump?

Is there 12V signal power (comes from the switch) to the two solenoids (extend and retract)on the Trombetta valve.

You can run the slide manually by using a drill motor and a 1/4" hex head tool. Peel the sticker off the head of the pump motor to find the connection point. Turning it one way extends and the other way retracts.

Here are some links to PDFs in the MOC Files section that may help:

I had a similar problem shortly after getting my rig in 2019. The dealer replaced the hydraulic pump under warranty but as it turned out, the switch was the problem.
Spent less than $10 replacing the switch in my inside panel and it has worked ever since.

Thanks for the reply and things to check. I hope to get if figured out now.

Don't know if you know this, but the drill won't help unless the pump isn't working via the electricity. Basically then you become the motor.

Make sure your batteries are FULLY CHARGED. Don't ask me how I know.
