Worn gasket behind inducer motor

blueman Member Posts: 11
The rubber gasket behind the draft inducer motor on one of our American Standard high efficiency condensing gas furnaces appears to be mostly corroded.

I have read elsewhere the suggestion to replace it with a silicon bead.

-- Is that considered good (and safe) practice or is that more of a "hack" type repair?

-- Would something like GE Silicon II caulk be appropriate or is there a special silicon engineered for this application?

Thanks for the help!

    The silicon repair should be a

    temporary repair until a new gasket can be ordered.

    RTV SIlicone

    Typically red in co;or is good up to 600*.  This may either be your final fix or like stated above, till the gasket arrives.  On an off note:  if you ever run into a boiler pump with a non stock gasket there is a product out call "Right Stuff".  I even used on a pool pumps 6 years ago and still holding.  Right stuff if your in a bind.  It does not have the temp ratting As the RTV, but great for gasket..

    No gasket, just RTV Silicone

    Just heard from  American Standard Tech support:

    "There is not a gasket for the inducer motor. It is actually silicone that the dealer applies that creates the seal."

    Thanks for all the help!
