30 Amp Fuse Keeps Blowing on LCI Stabilizer Jacks Between Campsites

Question:

2021 Rockwood 2511s LCI stabilizer jacks work fine when extending and retracting when setting up or breaking camp. However each time we get to the next campground the stabilizer 30 amp fuse in the main fuse panel is blown. Havent found any loose wires yet. Any ideas what might cause this. Thank you

If the jacks are working most of the time, but blowing the fuse between campsites, it is most likely a ground issue. This could be loose, but could also be just a bad connection somewhere. I suggest checking all your ground connections on both the trailer and vehicle, just to make sure.

One thing you could also try, is unplugging the trailer when starting the vehicle. It could be that the starting amps are getting too high for that fuse and causing it to blow. This is fairly unlikely and it is most likely a ground that has gone bad, it doesn't hurt to try as well.

If all the grounds look good, you may want to upgrade the fuse to a 40 amp circuit breaker, like the Circuit Breaker - 40 Amp - Perpendicular Mount Bracket - Cycling Auto Reset - Plastic - Type I # PK54240PL. This should keep it from blowing all the time.
