Furnace does not stay on
I have purchased a new 2011 Classic 30 and the furnace blower turns on, and I can hear the flame ignite, but it does not stay on for more than a few seconds. It will keep coming on, but does not stay running. It is under warranty, but if it is an easy fix, it would be much easier to take care of it myself. Access to the heating element does not look very good. Any thoughts?
Thanks

Are you on shore power and do you have plenty of propane? Either a low battery or lack of propane could cause the furnace to turn off. Also turn the furnace off at the switch and then restart it after switching to an open and full bottle of propane.

Barry,
Since you are under warranty, you should have the furnace thoroughly checked at a factory authorized Suburban dealer (I assume it is a Suburban furnace). There could me one of several issues: defective sail switch, defective ECO device, partially plugged LP orifice, defective gas valve and most important, a defective igniter board. I could go on about how to find and diagnose all of these, but if YOU do it you will void your warranty.

Hi,
For whatever it might be worth, earlier this winter my furnace was doing the same thing. I turned my furnace breaker and switch to off then carefully unpluged and repluged each electrical connection. I finally moved the right one that wasn't making proper contact. Its been working fine since then and it saved a long and expensive trip to the factory. If this doesn't work, check the sail switch next.

You can actually adjust the "regulator" on the furnace. All it takes is a screwdriver. I had the same problem when I first got mine and went camping with my brother who showed me how to adjust it. It's a simple fix.

Where is the regulator and what does it look like? Any photos?

First, I would check all the electrical connections and make sure they are clean. You can wipe them off with a clean rag or paper towel. WD-40 is a good cleaner and electricity can conduct through it. Since your trailer is pretty new, dirt or carbon build-up on the contacts sounds unlikely, but it is a good place to start. That way you also check for loose contacts at the same time.
Of course, Lew is right. And if you do want to play with it, make sure you don't leave any evidence like scratches from screwdrivers or other tools that will show you tried to fix it.
