Dometic 2662 refer PM question September 01, 2014, 08:20:08 pm Yahoo Message Number: 1483742007 MB with the Dometic 2662 refer in it. Looking at the manual in the maintenance section it mentions that the baffle and flue should be cleaned with a flue brush, once a year along with other items . Yet in the rear of the manual where they have a maintenance check list they don't list the baffle/flue at all as a needed PM. Has anyone done the baffle/flue cleaning? If so how in the bleep did you get the baffle removed? Access from the top requires a 2 inch thick arm that's about 2ft long and mine is not 2 inches. Would a part grabber lie this work? I suppose I could remove the refer from the wall but that seems excessive. Looking at other posts in irv2.com and rv.net many claim that it's not needed or just blow air up it ( and of course some that say blowing air up it, doesn't accomplish anything). And where did you buy or what did you use for a flue brush?JimWondering Wanda (until we get inspiration for a better name ;) currently in VT As an Amazon Associate Lazy Daze Owners' Group earns from qualifying purchases.

There are flue brushes to do the job, and if it were just a matter of taking the refrigerator vent lid off and running a brush down the tube, it would be pretty easy; the baffle position is the kicker.Soot and rust build-up inside the flue flue can be "sorta" cleaned by tapping the outside of the flue along its length as far as one can reach (I've used a screwdriver handle) to loosen stuff, blowing compressed air up the flue, then blowing all the debris that falls out of the flue out of the compartment. The burner assembly should be removed or covered for this operation, obviously. (Removed is better; the burner assembly might need cleaning, too, but that cheeseball Dometic sheet metal band-aid has to be removed to get to the burner!) This article (and there are others; a web search will bring them up) offers good advice and instructions on cleaning the refrigerator components (Pay particular attention to the burner jet orifice cleaning instructions, and be sure to turn off the refrigerator and the propane - and the electricity - before you start cleaning.)http://www.rvdoctor.com/2004/11/cleaning-servicing-rv-refrigerator.htmlBlowing compressed air *down* the flue i.e., from the roof vent, (after removing or covering the burner and doing the tapping routine on the flue to loosen stuff), is possible, but you'll have to dig the sealant out of the screw holes on the vent before removing it; if you do, I suggest "re-sealing" the screw holes when the vent is replaced. (Blowing compressed air from the flue bottom is easier, and I don't know that it results in less-effective cleaning.)Good luck. ;-)Joan
