Condition: This kit is only effective if the main shaft of the mechanism is intact and not broken. Error Description: The issue arises from the shaft controlling the mixing flap. Over time, the stops that position the flap for hot and cold air wear out, causing the shaft to rotate excessively. This leads to inadequate airflow and often results in the shaft getting stuck, jamming the mixing flap in one position.
