Can a blower fan be turned on in cool mode?

If the Y terminal is energized, it turns on the a/c outside unit, but not the blower fan. Typical thermostats will energize the G terminal when in cool mode, or when the fan is turned to manual “always on” mode. It sounds to me like the G terminal is not being energized.

How does an air conditioner blower motor work?

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.

Where is the a / C or heat pump fan?

What and Where is the A/C or Heat Pump Compressor/Condenser Unit Fan? The condenser unit fan is a blower that moves outdoor air across the condensing coil found in the outdoor compressor/condenser unit.

Where do I find the blower motor part number?

If you still have the owners manual, this part number can sometimes be included in the manual for convenience. Other options include removing the air conditioner blower motor from the AC unit and checking the label on the actual blower motor. Write this part number down for easy reference.

Is the a / C blower motor still original?

It just doesn’t cut it in the Georgia summer heat! – the blower motor turns just fine and doesn’t seem to have a lot of resistance to it, although the plastic fan portion itself is still labeled 2/99 so it is original. I’m not sure if the motor itself is original.

What should the voltage be on my fan blower?

You should get a voltage reading of approximately 24 volts AC. If you do not get any voltage reading, your low voltage transformer might need replacing or you are not getting high voltage to power the transformer.

Why does my fan blower not come on?

If it does not come on then you might have a control board fan relay that is not sending 120 volts to the blower motor or a bad blower motor winding. You might try to change wires (speeds) on the blower motor to see if that fixes the problem.
