What should I do if the blower is not working on my furnace?

If the blower is not working on your furnace, you should first check the power supply to the furnace and make sure it is turned on. If the power is on and the blower still isn't working, you may need to check the thermostat settings, the air filter, and the circuit breaker. If these steps don't solve the issue, it's best to contact a professional HVAC technician for further assistance.
