• If Blocked Exhaust error occurs when blower is running, check for
restrictions in exhaust pipe, including exhaust elbow, condensate
drain, and outside termination. Also check exhaust pipe installation
(size/length) per manual.
• If Blocked Exhaust error occurs before blower runs, make sure
pressure switch connections are clean and tight. Check pressure
switch continuity/resistance. Switch should be closed (continuity/0
ohms). Replace switch if open (no continuity).
• Other possible causes: high wind conditions and excessive
negative air pressure in building.
