York manufactures many different types of air handlers that circulate air through various types of heat exchangers and air conditioning systems. Blower fan motors on York air handlers are built to last for years. Eventually, parts in your York air handler can wear out or break. When that happens, trust Sears PartsDirect to have the repair parts you need to fix your York air handler.
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.
