These signs indicate a possible issue with the blower motor relay.

Essentially an on/off switch, the blower motor relay’s reactions start and end the heating process in HVAC systems by controlling the flow of current between the power source and the motor.īlower motor relays tend to wear out over time from the stress of constantly flicking back-and-forth. In a blower motor, the relay supplies the power that allows the fans to circulate warmed air. How to Identify a Failing Blower Motor Relay Variable speed motors are also more energy efficient since they can control small temperature shifts, multi-speed units don’t use as much fuel to heat up larger spaces.

Multi-speed models allow variable fan speeds, which can help alleviate cold spots and make other temperature adjustments.

These motors operate at a consistent speed until the desired temperature is achieved.

Single-speed units operate on an on/off switch.

There are two main types of blower motors. The blower motor then pulls the warm air out of the furnace and powers a fan that pushes heated air out through vents and into the structure’s rooms. When readings dip below the predetermined threshold, the thermostat signals the furnace to create heat. Sensors in the thermostat monitor the space’s temperature. In an HVAC system, the thermostat sets the conditions for engagement. Replacing a malfunctioning relay restores your system’s ability to keep your home, building, or vehicle comfortable. The blower motor relay is an essential component in a functioning HVAC system. Blower motors are a common component in a home, commercial, and automotive HVAC systems. This piece of equipment makes it possible for structures of all sizes to maintain a comfortable indoor climate. A blower motor is a mechanism that allows HVAC systems to distribute heated air.
