Suburban furnace troubleshooting help
I recently bought a used trailer and it has a suburban sf-25 furnace in it. It sat unused for a long time so I brought it home, cleaned it out, powered it up, connected propane and it worked as it was...

The most common failure I see in this model is the limit switch, which can be accessed from inside the trailer- remove the inside panel and it's right there. The tabs for the quick connects get oxidized, you can often fix it with a pencil eraser, or sometimes just disconnecting and reconnecting will do it.
