Air Conditioner Troubleshooting

Before you request dealer service, check for these easily solved problems:

09

Check the indoor and outdoor disconnect switches. Also check your main electrical panel circuit breakers or fuses.
Check for sufficient airflow. Air filter(s) should be reasonably clean and interior vents should be open and unobstructed.
Check thermostat settings. For cooling, your desired temperature setting should be LOWER than the displayed room temperature, and the System/Mode control should be on Cool or Auto. For heating, your temperature setting should be HIGHER than the displayed room temperature, and the System/Mode control is set to Heat or Auto.
Time delays — depending on the Bryant air conditioner you have, there may be delays in unit operation that are built–in to protect the equipment and your comfort. Don’t be alarmed if you notice a time delay in operation. It may be a standard protection feature of your equipment. Check with your Bryant Dealer for more information on time delays.
If you need to contact your Bryant dealer for troubleshooting and/or repairs, be sure to have the model and serial numbers of your equipment available (there are spaces on the cover for you to write this information). With this information, your dealer may be able to offer helpful suggestions over the phone or save valuable time through knowledgeable preparation for the service call.

Regular dealer maintenance

In addition to the routine maintenance that you perform, your home comfort system should be inspected regularly by a properly trained service technician. Many dealers offer this service at a reduced rate with a service contract. Some service contracts offer additional benefits such as parts discounts and no additional charge for ”after hours” or emergency service.
Your annual system inspection should include:
Routine inspection of air filter(s) with replacement or cleaning as required
Inspection and cleaning of the blower wheel housing and motor
Inspection and, if required, cleaning of indoor and outdoor coils
Inspection of the indoor coil drain pan, as well as the primary and secondary drain lines. If the system has an auxiliary drain pan and line, they should be inspected at this time as well. Service should include cleaning if required.
Check all electrical wiring and connections
Check for secure physical connections of individual parts in each unit
Operational check of the air conditioning system to determine actual working condition. Necessary repair and, r adjustment should be performed at this time.
