![]() ![]() The infrared beams of light are invisible to the naked eye. A remote control emits pulses of infrared light and those pulses are detected by a receiver, usually situated on the air conditioning unit itself. ![]() Most air conditioner remote controls rely on infrared technology (IR). Knowing how to differentiate between air conditioner remote controls that you can fix yourself and ones that need expert help can save you money, and possibly your life. You tend to take it for granted…until it stops working. Your air conditioner remote is a godsend in the hotter months of the year, allowing you to easily adjust the temperature with minimal effort. Nowadays, they’re so commonplace that it’s not unusual to have at least half a dozen different remote control devices around the house. A remote control would have been regarded as an instrument of black magic or witchcraft. It's connected to a small plastic drain tube that directs the moisture outside your home.Only a few hundred years ago, no-one would have dreamed that you could control something without even touching it. Drain port: A small hole in the back of the drain pan.The drain pan is tilted at an angle towards the back of the unit to direct the moisture into the drain port, and to prevent moisture from leaking into your room. Drain pan: The pan on the bottom of the unit that collects the moisture produced from the evaporator.The thermostat is often a small copper tube about three or four inches long, and usually clipped onto the front of the evaporator. Thermostat: Responsible for sensing the room's temperature to regulate the air conditioner's on/off cycle.Blower: Located on the other side of the fan, the blower pulls the room's hot air over the evaporator coils to cool it down before recirculating it back into the room.Compressor fan: Blows outside air against the compressor coils to cool them.The capacitor usually connects to the compressor and fan motor with two electrical terminals that protrude from the top of the cylinder. Capacitor: A cylindrical device that stores an electrical charge to start and operate the compressor and fan motor.The compressor is typically located between the evaporator and condenser and is operated by an internal motor (compressor motor). Compressor: Compresses the refrigerant into a hot liquid for the condenser and a cold liquid for the evaporator.Refrigerant: A liquid (in the condenser) or gaseous (in the evaporator) compound that circulates through the air conditioner’s evaporator and condenser coils to capture and/or cool hot air.Condenser: Located on the very back of the unit, the condenser has the same components as the evaporator (copper tubing, fins, and refrigerant), but it captures the room's hot air and releases it outdoors with a fan (the condenser fan).The evaporator coil contains refrigerant to convert your room's hot air into cold air. Evaporator: Located directly behind the filter, the evaporator is composed of copper tubing (evaporator coil) surrounded by thin aluminum fins.The filter will either be located inside or directly behind the face panel. Filter: A thin, pleated screen that protects the air conditioner’s internal components from the damaging effects of dirt and debris and cleans the air before it's recirculated back into the room.Depending on the unit, the face panel may be held in place by screws, tabs and clips, or both. The face panel is the first thing that needs to be removed to access the rest of the air conditioner's parts. Face panel: Also known as the grille cover, this is the plastic or metal cover attached to the front of your air conditioner. ![]()
