Indoor fan not working on ac unit. Thats your cue to turn the system off and call the pros to repair the ac fan motor. When an outside fan fails the most likely cause is a capacitor issue. Fans in the central ac both pull air out of the room to be conditioned and have humidity removed and also push chilled air through the vents throughout the house. If it is in the air conditioning mode check for ice around the evaporator coil and on the refrigerant lines at the indoor unit.
Relay boards are often misdiagnosed. If the compressor is working but the fan blades are not spinning the motor is faulty. If you arent getting 24 volts between g and c then you might have a thermostat problem a thermostat wire problem or the low voltage fuse on the control board might be blown. Call maintenance as that is why you pay rent.
Test to make sure you are getting 24 to 28 volts ac between the g green and c com terminals on you fan center or control board. Air conditioner outside unit fan not working bad capacitors. 6 inspect the capacitor. If the fan isnt working that can cause the coil to freeze.

Before replacing the board make sure you check more commonly defective partsparticularly the fan motor capacitor and the fan motor itself. What your hvac technician will do replacing an hvac motor is a job that can be done quickly once the problem is identified. Anything that inhibits adequate power supply to the fan assembly may cause the outside fan to.
If the coil is frozen shut off the air conditioning immediately. If they move freely go back inside turn the ac back on and use your tool again to kick start the fan blades. Capacitors store up the energy. If you are satisfied that the thermostat settings are correct check your power supply.
If the coil froze the fan could be working but the air wont go through the ice until it melts. While each component in a central air conditioner is critical quite simply the unit will not work if the fan is not running.
