I own a 2025 Enlighten 17bh. Our microwave, which we have just now used when grandchildren camped with us, kept shutting itself off during use and the inside got hot. We checked breakers and fuse and nothing was wrong. After researching this problem on the web, it gave a few different reasons. It could be the fact that there isn't any real ventilation that I can see. Has anyone else had this problem with a 17bh or any other trailer type?
