Specs At A Glance

Good To Know

Q: Why does the fan only work on the high setting? A: When an HVAC Heater Blower Fan Resistor fails, it often loses the ability to manage lower voltages, leaving only the direct high speed circuit functional.

Q: Is it necessary to check the blower motor when replacing this part? A: A failing blower motor can draw excessive current and cause the new resistor to fail prematurely, so checking the motor for resistance is recommended.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
