A CHECK-UP CHECKLIST
Your furnace represents an important investment in your family’s comfort and your home’s value. To keep it performing properly and
to prevent future problems, have a trained qualified agency service specialist give your furnace a professional check-up annually. The
following checklist can be used as a guideline to proper service:
• Inspect all flue gas passages, burners, heat exchangers, coupling box(es), and inducer assembly.
• Inspect all combustion-air and vent piping inside structure and pipe terminations outside the structure for leaks.
• Check gas pipes leading to and inside of your furnace for leaks.
• Inspect and clean the blower motor and wheel.
NOTE:
The inducer and blower motors are pre-lubricated and require no additional lubrication. These motors can be identified by
the absence of oil ports on each end of the motor.
• Inspect and change or clean air filter(s) if necessary.
• Inspect the return-air duct connection(s) at the furnace to ensure it is physically sound, sealed to the furnace casing, and terminates
outside the space containing the furnace.
• Inspect all supply- and return-air ducts for obstructions, air leaks, and insulation. Remedy any problem when necessary.
• Inspect electrical wiring, connections, and components for loose connections.
• Perform an operational checkout to determine whether your furnace is working properly and if it requires adjustments.
• Inspect all condensate drain tubes and condensate trap assembly for leaks. The condensate removal system should be cleaned
annually by a qualified service agency. Refer to the Service Guide for further information.
• Examine the physical support of the furnace. The support should be sound with no cracks, sagging, gaps, etc. around the base.
• Check furnace for any obvious signs of deterioration.
BEFORE YOU REQUEST A SERVICE CALL
If your furnace is not operating or not performing properly, you may save the expense of a service call by checking a few things
yourself before calling for service.
FOR INSUFFICIENT AIRFLOW:
• Check for dirty air filter(s).
• Check for blocked return-air or supply-air grilles throughout your home. Ensure they are open and unobstructed.
If problem still exists, call your dealer for service.
IF FURNACE FAILS TO OPERATE:
Follow this checklist step by step, advancing to the next step only if furnace fails to start.
• Check thermostat for proper temperature. Is thermostat set above room temperature?
