Triangle Tube Excellence, E-29 Error Message

in THE MAIN WALL
This is on a boiler we installed 9 years ago and it started throwing out this error message periodically. The troubleshooting guide says, "The control module is detecting the blower in operation when it should not be". TT tech. support said that replacing the blower motor usually takes care of the problem. We did and the problem persists.

Tech. support now says to look through the venturi to see if the blower is spinning the next time this happens. If it is spinning, replace the blower (again). If not, the control board is suspect.

I'm posting this to see if it's happened to anyone else and what the outcome was.

    Does a pressure switch prove the fan operation?
    If so switch could be stuck??

    Could be poor communication between motor and control board. I would definitely clean comm cable connectors.

    The solution was to replace the MCBA board.
