Common York air handler replacement parts

• Electronic control board. The electronic control board receives signals from the thermostat and sends current to the fan motor to circulate air.
• Thermostat. The thermostat monitors temperature in the home and sends signals to the air handler control board to control air handler operations.
• Blower fan motor. The blower fan motor spins the blower wheel to circulate air through the heat exchanger and the home.
• Transformer. The transformer converts high-voltage AC power to low voltage DC power which is used by electronic control boards to control the air handler.

Top reasons why your York air handler won't work

• Lack of power. Check the house circuit breakers for the air handler. Reset the circuit breakers if they're tripped.
• Failed electronic control board. Shut off power to the air handler for 1 minute then restore power to reset the electronic control board. If that doesn't work, then you may need to replace the electronic control board.
• Bad transformer. A bad transformer won't send low voltage DC power to electronic control components so the air handler won't work. Replace the transformer is it doesn't send DC current to the controls.
• Thermostat problems. Check the thermostat settings and adjust the settings if needed. If the thermostat is bad, you'll need to replace it.
• Bad blower fan motor. If the blower fan motor gets power and doesn't run, you'll likely need to replace the blower motor.
