How do I reset a blower motor?

Resetting a residential indoor air handler blower motor involves addressing thermal overload protection switches or performing a complete electrical power cycle on the system. Many modern ECM and standard blower motors are equipped with an internal automatic thermal overload sensor that temporarily shuts the motor down if it overheats due to a restricted air filter or excessive friction; once the motor cools down completely—which can take thirty to sixty minutes—it will automatically reset. To force a full system reboot, turn off your thermostat, switch off the dedicated HVAC circuit breaker at your main electrical panel for five full minutes, and switch it back on. You can verify that your reset was successful when powering the system back on allows the blower motor to engage smoothly and circulate air through your home's ductwork normally.
