Code: CT204-9921
Product Details
- Aftermarket Replacement For
- CAT
- Warranty
- 6 months
A damaged speed control resistor can disrupt HVAC fan operation, leading to a loss of adjustable airflow. During troubleshooting, a resistor that fails open may cause the blower to run only at the highest setting. Keeping a resistor in sound condition helps maintain consistent fan speed regulation. This aftermarket replacement part references the OE maker CAT and cross-references part number CT204-9921. The resistor limits electrical current to control motor speed through a series of wire-wound coils. A common failure mode is overheating from prolonged high-speed use, which can crack the ceramic core. Verify the serial number or application, then call (562) 693-7748.
