we had a problem with ours - very similar. It ended up being that the motor for the jacks was having a short that tripped the circuit breaker. We reset the circuit breaker, ran through all the resets in the troubleshooting guide and finally gave up and took it to the dealer. After about 3 days of troubleshooting, they figured out the motor was causing a short - the whole thing had to be replaced (under warranty)
It took a few weeks to order, so we just didn't have any leveling jacks for a few camping trips.
They've been trouble free since then.
