This may not be the place to post this, but until I get better with this forum, here goes. I have a 2018 305RL and I’m dealing with an electrical issue. The circuit that the overhead fan, bedroom, kitchen island, bathroom and coffee bar receptacles are on, the power goes out. It’s only happened today and one other time... 14 months ago. It doesn’t trip the 15 amp breaker. Power comes back on after a period of time, minutes or hours. I replaced the breaker the first time it happened, not sure it helped because problem is back.
Any suggestions for a fix, thanks
