Top reasons why your Kenmore 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.

Kenmore air handler safety tips

• Conduct yearly maintenance. Have a HVAC service technician inspect, clean and perform required maintenance on your air handler annually. The service technician will examine the unit thoroughly for possible safety hazards such as worn components and shorts in the electrical system.
• Change the air filters regularly. The air filters remove contaminants from the air in your home. Use allergen air filters to remove dust and pollen that can cause breathing problems.
• Disconnect electrical power from the air handler anytime you perform maintenance or access internal wiring or components to complete repairs.
• Read and follow all operational and safety instructions in the owner's manual for your air handler.
• Have a service technician examine and repair the air handler whenever it fails and you're not able to fix the problem with simple troubleshooting steps described in the owner's manual.
