Hey guys I have an Outback 323BH with the Suburban Model SF-30FQ. I have had intermediate problems with the furnaces since we got it in 2015. What happens is it will blow for 30 sec and shut off.
I have propane I can run everything on propane in the camper they all work. I have replace the regulator just in case.
When I turn the thermostat on you hear the click at the thermostat and then the blower comes on. It will run for 30 sec and shut off.
If I pull the unit out of the camper and bench test it with the 12 volte battery from the camper it works find. Now keep in mind I'm not running propane to it but you turn it on it blows for 15 sec and then you hear the click of the gas valve and the multiple clicks of the ignitor. Then nothing but the blower and then again the click of the gas valve and the multiple clicks of the ignitor and then again same thing after 15 sec and then the unit will shut down.
Put it back in the camper and it might work for a day or two and then the same thing the unit shuts down sometime in the night and will not re light blows for 30 sec no click of the gas valve and it will not start till I pull it out of the camper test it on a bench and it works.
I the ducks are not clogged in the camper so I don't think I'm hitting the over limit switch I don't have a thermostat problem because the bower motor starts right away when I turn it off and back on. I have replaced the sail switch but I think the old one was fine I tested it with a meter. Still the same problem it has been in the dealership 4 times all they have done is replace the gas valve and tell me it's working I get it home and it does the same thing.
I am at a lose here guys Please help.
