SHACMAN A/C System – Heater Motor Assembly / Blower Assembly DZ14251841103
Routine Maintenance Recommendations
1. Regularly replace the air conditioning filter: A heavily soiled filter increases air intake resistance, forcing the motor to operate under an overload for extended periods; this accelerates coil aging and can lead to burnout. It is recommended to replace the filter every 10,000 to 20,000 kilometers or during the seasonal transition between spring and autumn.
2. Run the fan at high speed to clear out dust before the change of seasons: During seasonal transitions when the air conditioner has not been used for a long time, it is advisable to park in an open area and run the fan at its maximum setting for 5–10 minutes. This helps blow out accumulated fine dust and moisture, preventing the motor bearings from seizing.
