I have a Rockwood 2703SS
When we first started the furnace/air it clicked on fine but when it reached it's temp & shut down it would not come back on when the temp got colder in the camper. Took the thermostat cover off & there is a glass fuse that I replaced & worked fine for that initial turn on but would not cycle again. When I went to pull the glass fuse out I used a butterknife because that's all I had handy, when I touched the connections when pulling out the fuse the furnace/air would work
If I keep the fuse in & use some type of metal piece touching it the unit will run. It's weird & I can't figure it out
