I have a 2015 Reflect 323BHS. We have used the heater since we bought and it worked fine. We have been running the heater while it sits in our driveway (keeping the thermostat on 60) because we are going on one last trip for Thanksgiving. Went out to it this morning and the heat is not running...and it is cold inside. Checked the gas...good. Checked the furnace fuse...good. Turned the thermostat off and then on again...still nothing. Is there something else I can check or is something likely broke?
