Heat pump not cooling

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

Heat pump not heating

The main control board regulates the power supply to all of the components of the furnace or heat pump system. If the control board fails, it might not send voltage to the ignition system, causing the unit not to heat.

Heat pump won't turn off

If the heat pump won't turn off, a possible cause is a shorted component on the heat pump's main control board. While this is not a common problem, if all other potentially faulty components are working properly, the control board should be replaced.
