EXTERNAL AIR FILTERS Your residential filter could be one of three types: disposable, washable, or electronic. Before you clean or replace your filter, you must switch off your system. Replace disposable filters as needed with a new filter of the same proportions. If you own an electronic filter, consult your owner’s manual for maintenance tips.
If during your inspection you notice any cracks or water damage in the drain line, do not operate the heater. Contact your Carrier dealer for servicing.
BLOWER CARE Blower wheels and motors should be inspected for dust. The entire blower should be inspected annually.
Remember, only certified professionals, like your Carrier dealer, are qualified to perform maintenance. Your furnace’s gas supplies should be switched off before servicing.

THE COIL Make sure that there is nothing obstructing your outdoor unit’s air flow, including grass, leaves, plants, or paper. To clean the coil, you may vacuum it or wash it down with a garden hose after switching off the main disconnect. Keep the fan motor and control box as dry as possible. After cleaning the coil, flush any dirt from the base pan.
Caution: You should contact your Carrier dealer to have your coil installed, serviced, or replaced.
FAN MOTORS Normally, your motor should not need oiling for years. If it does, check your unit for motor lubrication ports first. Use 10-15 drops or ¼ tsp of SAE 20 non-detergent electric motor oil or automobile oil ONLY to lubricate each bearing. If you have an add-on type system, you should do the same for the furnace blower motor.
