The second day we owned our new to us 2007 Cougar 5th wheel, the fuse blew on our landing gear and I replaced three times without being able to lower the landing gear. Very frustrated I called the dealership we purchased from and they asked me to bring it right in. The sevice rep and tech said it appeared the landing gear had been raised too high (found out during discussions this a problem because there is no cutoff to prevent) and the landing gear shaft had probably previously been slightly bent causing it to be lodged in the retracted position. They also noted that they had forgot to mark the landing gear where the retraction should stop. The dealership was great, they replaced the landing gear that was causing the problem at no cost to us. Had to laugh as the tech who was doing the demonstation after the repair, retracted the landing gear too far, when he was preparing to mark it and it blew the fuse. They were very apologetic for not covering this situation in the walk through. Bottom line in my opinion you should never retract the gear until it ratchets (as I did), you should find a level and mark the landing gear to prevent future problems. By the way, this was our first RV with power landing gear, so every new system I have to remember I am a rookie, this forum has become a great resource for us.
