Air handler blower not running/not turning on

The control board regulates the power supply to all of the components of the furnace or air handler. If the control board is defective, it might not send voltage to the blower motor.

Air handler blower runs all the time

The control board has relays that regulate the voltage to each component in the furnace or air handler. If the relay that controls the blower motor fails while it is closed, it will send continuous voltage to the blower motor, causing the motor to run continuously. If the control board is at fault, replace it.

Air handler not heating

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

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 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

If the blower won't run, a likely cause is a defective relay or other component on the furnace or air handler control board. If power is not getting to the motor, and the run capacitor (if applicable) is functioning properly, the control board should be replaced.

Heat pump won't turn on

If the heat pump unit contactor is not receiving 24 volts or power is not getting to the inside blower motor, a possible cause is a defective heat pump 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 compressor won't run

If the heat pump unit contactor is not receiving 24 volts or power is not getting to the inside blower motor, a possible cause is a defective furnace or air handler 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 won't turn off

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

Air handler has a burning smell

The control board regulates the power supply to all of the components of the air handler. If a component on the  control board fails it can produce a burning smell. If the control board is burnt it will need to be replaced. 


Air handler not cooling properly

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


Air handler is frequently cycling/short cycling

The control board regulates the power supply to all of the components of the air handler. If the control board fails, it might not send voltage to parts of the heating system, causing a loss of heat and frequent cycling.


Air handler circuit breaker keeps tripping

The control board regulates the power supply to all of the components of the air handler. If the control board shorts out it can trip the circuit breaker. A shorted control board will usually have burn marks or smell burnt and will need to be replaced.


Air handler wall thermostat not working properly

The control board regulates the power supply to all of the components in the system. If the control board fails, it might not send voltage to the thermostat, leaving the thermostat inoperable.


Heat pump is frequently cycling/short cycling

The control board regulates the power supply to all of the components of the furnace or air handler and heat pump. If the control board fails, it might not send voltage to parts of the system, causing a loss of heat or cooling and frequent cycling.


Heat pump - home's humidity is too high

	The 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.

Heat pump circuit breaker keeps tripping

The control board regulates the power supply to all of the components of the heat pump. If the control board shorts out it can trip the circuit breaker. A shorted control board will usually have burn marks or smell burnt and will need to be replaced.
