Air Conditioner Troubleshooting

If your AC system is not working correctly, air conditioner troubleshooting is what you should think of. The first thing you need to make sure is that your thermostat has been set to a lower temperature than the room’s temperature. The mode should be switched onto ‘cool’. Also make sure that the thermostat has fresh batteries.

The next thing of air conditioner troubleshooting is to check the power by turning the switch of the fan to ‘on’ from ‘auto’. In case nothing happens, it means that the control has been burned or the power has been disconnected. But, if the air blower works, it means that the power is there. If your system uses a furnace to create heat, confirm if the emergency button has been switched on.

If you know the circuit breaker panel or fuse, look up for tripped breakers or blown fuses. Fix up the problem only once. If the problem repeats, it is advisable to call for a trained technician.
At the time of air conditioner troubleshooting, when the fan is aimed to ‘auto’ and selector switch to ‘cool’, turn the thermostat down than the actual room temperature. If the condenser doesn’t work, but the blower does, examine the circuit breaker panel. The problem may be with the condenser if the breaker is working correctly.

Some of them may have a high-pressure cutout. This is a button that sticks out from the outside of the cabinet, usually next to the refrigerant pipes. Press and hold it inside as long as possible to reset it. If both the things are working rightly, but still there is no cooling, check the bigger copper line in the condenser.

A warm copper line tells that either the compressor has turned down or the system is not functioning. On the other hand, a cold copper line means that there are some problems with the airflow inside, such as a clogged filter and others. A lower charge of freon also causes freezing. Shut down the system and allow it to melt entirely. In case, after air conditioner troubleshooting, it freezes again, look for a professional
