If your blower motor starts then shuts off, it may be due to a variety of reasons. Overheating can cause the motor to shut down as a safety measure. Check for clogs or blockages in the vents and filter, and replace or clean as necessary. Inspect the capacitor, as it may be failing and needs replacement. A faulty thermostat or a malfunctioning control board could also disrupt the motor's function. If simple troubleshooting doesn't resolve the issue, it's best to consult with a professional for a thorough inspection and repair.
