Official Haier air handler parts

Common parts that fail in Haier air handlers

• Blower fan motor. The blower fan motor spins the blower wheel to circulate air through the evaporator and into your home. You'll need to replace the blower fan motor if it's getting current but won't run.
• Evaporator coils. Evaporator coils are part of the heat exchange system. These coils remove heat from the air. If the coils are dirty or damaged, they'll need to be cleaned or replaced to work properly.
• Thermostat. The thermostat detects the temperature inside your home and turns the air handler and air conditioner or heater on and off to maintain the set temperature inside your home. You'll need to replace the thermostat if it isn't detecting temperature properly or it isn't turning on the air handler and air conditioner or heater.
• Air filter. The air filter removes fine particulates from the air to protect the internal components of the air handler and helps improve the air quality inside your home. If the filter is too dirty, then it may restrict air flow and will need to be replaced.

Top reasons why your Haier 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.
