... 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!
