What does 29 mean?
Rheem error code 29 indicates an abnormality with the fan motor. This usually means the system's control board isn't receiving the expected feedback from the fan, or that the fan isn't operating within the expected speed range. The fan motor is responsible for exhausting combustion gases safely out of your home. When it malfunctions, the system shuts down as a safety precaution to prevent dangerous gases from building up inside your home. This code can appear on tankless water heaters or furnaces.
