Where is the furnace access panel...

[SLCaton]

... in our 2008 Sandpiper 345RET? I've looked outside & in but cannot locate the access panel. My furnace no longer 'kicks on' and it is no longer heating.

Before you ask, yes, both propane cylinders are full and appear to be functioning (the gas stove & oven work fine - I've checked!) The heater has worked wonderfully for almost 2 years but suddenly does not. I was told to locate the 'access panel' (and potentially replace the 'board'...) but I've never needed to know where it is till now!

Any suggestions?

There may not be one on the outside. Look for a wood or metal grill low on a wall somewhere. It would be much larger than a floor grill. The furnace would be behind that.

I'm not familiar with your trailer but in my 08 the furnace panel looks
like every other cabinet door in the trailer except this panel has
a dark colored screen in the center rather than a painted panel.

Look near the floor for this screen panel.
Also go outside and look for the chrome flue outlet on the
wall. The furnace is directly inside behind this flue vent.

Good luck!

I think the exhaust flute is just ahead of the water heater access panel. The furnace will be directly behind that flute.
