Furnace will not run

We have a 2011 Landmark August we purchased used and are checking out all the toys inside.
Furnace clicks and does the whooshing sound but does not light. Checked out everything suggested in this thread and all is good.

QUESTION: How do you replace the main regulator? From posts this sounds like the problem.
We don't need to take to a dealer do we? Can we do this ourselves?

Hi Kandy,

It's not hard to change the regulator, but there are obvious safety issues. If you make a mistake, because you're working with an explosive fuel, the consequences could be quite serious. If you're not sure of what you're doing, pay an expert.

Before starting:

You'll need a set of wrenches to fit the various fittings. You'll probably need two wrenches to remove some fittings (one on each side of the fitting).

You'll also need Teflon Tape for LP fittings - not the teflon tape for water fittings. Tape for LP is marked as such and is a different color.

You'll need a leak tester solution. If you can't find any, a soapy water solution that is capable of making bubbles should work.

Examine the new regulator to determine if the fittings appear to be the same size as on the old. If they're not, you'll have to locate adapter fittings. Sometimes these will have inverted flares. Sometimes pipe threads. If you're not sure, don't guess; get help.

To remove the current regulator:


  1. Shut off both propane tanks.
  2. Remove the tank by the auto-change regulator.
  3. Remove the screws mounting the regulator to the wall.
  4. Use wrenches to disconnect from the regulator the short pigtail that goes to the tank on that side.
  5. Use a wrench to disconnect the hose coming from the door side tank.
  6. Use a wrench to disconnect the hose coming out the bottom of the regulator. While it's disconnected, position it so that any accumulated oil can drain out of the hose.
  7. Reverse the process to connect the new regulator. Apply the teflon tape carefully making sure that nothing gets inside the fittings. I usually wrap 2 times around. Wrap in a direction so when putting the fittings together, the tape is tightened, not loosened.
  8. After everything is back in place, reconnect the tanks. Slowly open the tank valves and test all connections for leaks. If using a soap solution, liberally coat the fitting. With gas turned ON, there should be NO bubbles forming.

In my experience, the hardest part of changing the regulator is when the fittings are different. It can be very difficult to find the correct adapters. The second hardest part is that sometimes the current fittings are very difficult to unscrew.

Again, if you're not sure what you're doing, pay an expert.
