Hi, I attempted to service this Rheem brand forced air natural gas furnace that runs for approximately 5 minutes before shutting off so after some troubleshooting I noticed that it seems to overheat if the air filter is in place by means of the over limit temperature safety switch. I recently removed the blower motor and cleaned caked on dust that coated the blower motor fins so that improved the air flow however I feel there's something else wrong in addition to the caked on dust, perhaps a birds nest or something blocking the exhaust perhaps? I was considering removing the draft inducer to check for surprises. Anyone?

MODEL# RGDG-05EAUER
SERIAL# DF5D302 F4695 5617

Thank you
