Central air conditioner not cooling properly

If the central air condensing unit contactor is not receiving 24 volts or power is not getting to the furnace blower motor, a possible cause is a defective furnace main control board. While this is not a common problem, if all other potentially faulty components are working properly, the main control board should be replaced.

Central air conditioner won't turn off

If the furnace's main control board has a short, it may be providing continuous voltage to the central air condensing unit preventing it from turning off. Inspect the control board for any damage and replace if necessary.

Central air conditioner - home's humidity is too high

The main control board regulates the voltage to the compressor and the fan motor. If the control board fails, some components will not function properly or will not work at all. Control boards are often misdiagnosed; make sure to check more commonly defective parts first before replacing the control board.
