Checked for rags, nests in the fan. It is clear. With it running, it was definitely recirculating it's own air. Installed baffle to correct. Shut it off and same thing. Code 37. Pulled control module and heat sink was very dirty. Cleaned heat sink and reassembled and still code 37. Looks like the module is bad. Probably too many overheating cycles on it. All wiring connections clean and tight too.
