Bryant Plus 90 furnace (Model 398AAV060100) installed in 1992.
Have a slow leak out of the draft inducer motor housing. Technician came out, dismantled the housing, installed an orange colored silicone sealant from a tube, told me to wait 12 hours before turning on the furnace. I waited 20 hours, and after about 8 hours of running the furnace the leak started again, but somewhat slower. Second service call, the technician did the same thing, same result.
He said if this doesn't work, the next step is to replace the housing (about $300+ for the part). Does this sound logical? I cannot see any cracks in the plastic housing. Would there be an OEM cut gasket instead of the silicon adhesive that would be better?
