Hvac blower fan motor not working. This is another common reason behind faulty. We will go over a few things to check before calling for service. Purpose of the fan center relay. Acservicetech goes over what to look for in the system components that.
We have many people ask how can i find out why my fan blower motor is not working why does my fan motor not work when i turn on my furnace or air conditioner answer. If the blower motor fails to start nothing happens. The first thing to do is check the relay or voltage from the board. If no voltage is recorded you will have to replace the board or the relay.
First make sure there is power to the indoor unit and that a switch or breaker isn t off. Now put your furnace s blower fan to the test. No indoor fan fan not running fan not blowing no airflow. As explained in the hvac blower motor guide an air conditioner blower motor and assembly is basically the fan inside the air conditioning system that forces the cooled air via the ac cooling coil through the vents and into the room space that is being conditioned this makes the air conditioner blower motor assembly one of the most important parts of your air conditioning system.
If there is a battery check if it is working properly. I found a real good youtube video made by acservicetech that explains the top 10 reasons why fan blower motors will not come on. The purpose of the fan center relay is to provide a low voltage control 24 volts to control a relay that can be used to control two speed blower motors and auxiliary circuits in heating or cooling equipment many of the newer furnaces do not have fan center relays but many of the older furnaces and some new furnaces still do. The blower motor starts turning fan blades that circulate cold air from the evaporator coils through the home s ductwork and into each room.
If you see or hear the fan turn on your blower motor is not the culprit.
