The story so far...

Landing gear came worked fine this morning (extended to hitch to truck; retracted for storage)

At new campsite tonight they won't extend but will retract.

I got them down manually with the handle to stabilize the 5th wheel for tonight.

Any ideas why they go up but not down?

Thanks!

It helps if we know what brand of gear we are discussing.

The only name I can find is "Venture Mfg Co"

If it helps the RV is a 2008 Dutchmen Monte Vista 33re

Bad contact on the switch.

I'll 2X that.

That's what I'm hoping. Didn't get chance to check last night it was getting dark as we arrived!

I would also check the switch first as that sounds like a strong possibility. Most likely you have a switch that is open in the center position and closed either of the other two positions(raise & lower). It may have one bad set of contacts. You can easily check it with an ohm meter, or as a quick test just use a jumper wire to connect between the lower contacts and the center. It will be very helpful if you have a multi-meter and are familiar with it's use.
