Title: suburban NT-16SE wall Furnace problems
Post by: cic317 on September 01, 2019, 11:00:54 AM
This dreaded furnace is acting up again.
Camper has been stored for a while, now up for sale. Going thru systems to make sure all is good, Furnace wont fire.
Full bottle of propane, bleed lines, turn on heat only thermostat, nothing. Jump leads in thermostat, fan kicks on but unit doesn't fire.Can't even hear it trying to fire.
Any Ideas on where to start?
Thanks

Update-
Took furnace out, blew out combustion chamber, all clean check in /out tubes clean, still not firing.
Unit fan runs 15/20 seconds then shuts down
Tried to jump out sail switch, No luck. Wondering if jumping it is a viable test?
The suburban service manual doesn't give values to test it, hoping one of the experts have an idea
