The HVAC blower motor regulator is a mechanism that helps adjust the blower motor's speed in the heating system.
Blower motor regulator significanceThe blower motor regulator is an essential component that allows the controlling of the fan speed. The regulator includes a set of three resistors that produce voltage to vary the speed of the blower motor. The fan has different speed settings and each speed of the fan causes the current to travel via various resistors.
Common problems with a faulty blower motor regulatorA malfunctioning HVAC blower motor regulator can lead to poor airflow, overheating, or erratic fan speed.
