Troubleshooting Tips for Motors for Air Conditioners

Every central HVAC system needs expert maintenance at least annually to operate with peak efficiency. Between professional service calls, there are some basic steps that owners may take to ensure proper mechanical functioning. Simple tasks like frequent filter and fuse replacement and washing components can significantly extend the useful lifespan of A/C units.

Following are some self-help methods to determine when professional intervention is required to fix parts or replace motors for air conditioners.

Motor Stops Running

Air condenser malfunction can have several causes. Two very common reasons are tripped electrical breakers and blown fuses. Either event disrupts the flow of energy that runs the device. Excessively high temperature settings can also cause the condenser to overheat. Resetting the thermostat about five degrees lower may cool the condenser enough to resume operating.

If the compressor or motor is defective or damaged beyond repair, expert installation of a total replacement is necessary. Inconsistent cooling that occurs due to imbalanced distribution also requires professional assistance.

If the motor works but cooling is inadequate, perform a few preliminary checks before calling an expert. Again, you should begin by examining the thermostat setting. Lowering it a few degrees may solve the problem. If that doesn’t work, inspect the evaporator coil and condenser unit for excessive dust and debris accumulation.

Carefully remove and clean both parts thoroughly by rinsing with plain water for several minutes. Next, wipe off and realign condenser fins. In some cases, airflow into the condenser can get obstructed by exterior barriers. Cut any weeds near your HVAC unit. Some more serious causes of compressor malfunction are defective parts and Freon deficiency or leakage. All those matters call for professional assistance to repair properly.

Motor Turns Off and On Constantly

When condensers turn on and off constantly, blockage or excessive dirt or grime buildup are likely causes. Eliminate any foreign matter that has become lodged inside the unit and wash the fins and coil completely. A dirty evaporating unit may be the culprit, too. Remove and rinse it off to see if that restores normal operation.

If not, seek experienced repair service immediately. On many occasions, simple things like cleaning off essential components is enough to cure a cooling problem.

However, when these easy DIY repairs do not seem to do the trick, your best bet is contacting a qualified air conditioning repair service immediately. Trying to make big repairs without proper training and the right tools and equipment typically winds up compounding the problem and expense.

When it comes to keeping motors for air conditioners running well throughout hot summer months, an ounce of prevention is literally worth many pounds of cure.

Annual AC Checks are Key

Annual checks and routine maintenance can nip many disasters in the bud before they even begin. Standard maintenance usually includes refrigerant level checks, electrical component inspections, evaporator coil cleansing, condenser coil cleaning, motor oiling, thermostat calibration and filter replacement or cleaning.

Every one of these individual services contributes to prolonged air conditioning system useful life. Not to mention adding to significant long-term savings by maximizing efficiency that minimizes energy and repair bills!
