Standard Motor Products Blower Resistor

The Standard Motor Products blower motor resistor (also called a blower resistor, blower motor speed control resistor, or HVAC fan resistor) controls the fan speed of your heating and air conditioning system. It regulates the electrical current sent to the blower motor, which gives you the different fan speed settings on the climate control panel.

Key Features:

• Restores fan speed control when the blower works on only one speed or not at all
• Designed to match the form, fit, and function of the original part
• Built with durable electrical components and connectors intended for the heat cycling of an HVAC system
• Backed by Standard Motor Products, a long-established name in engine management and temperature control parts
• Available in multiple variants to suit a wide range of applications

A failing blower motor resistor commonly causes the fan to work only on high speed, to lose some speeds, or to stop entirely. Replacing it restores reliable airflow for heating, cooling, and defrosting. Choose the specific part number that matches your application.
