Your description your model series is SF. Probably an SF-35Q, my hunch. Pulling back panel that contains 3 discharge ducts will reveal a logo (sticker) of model number. Also limit switch with 2 wires attached is also right there. If your handy and can swing a wrench, just replace limit switch yourself. Also add an additional 4th 3" vent from the side not used and determine where you can route it to interior based on cabinetry, routing location. Cost is cheaper than gas to take rv into dealer, and your downtime that you don't have your rv. You will get the satisfaction of fixing it yourself. Also dealer probably won't be successful in resolving issue unless they add an additional vent anyway. There is no downside to additional vent as long as you have the real estate for routing the ducting and a discharge vent location.
