Front Landing Legs Worked and now they Don't

[Dhall]

Hello everyone. I'm having an issue with the front landing legs on my 2006 Montana 3500RL. I was able to operate them to hook up my truck today, they operated both up and down.

When I went to unhook I hit the switch and had nothing. I ended up extending the landing legs manually. My battery is fully charged and I'm hooked up to shore power. I replaced the 30A Fuse and the Re-settable Breaker but still have nothing at the switch.

Any suggestions?

Thanks,

Dennis
