1.) Capacitor –
The capacitor is responsible for delivering a jolt of electricity when your air conditioner first turns on. This helps begin the cooling process. Once the AC is up and running the capacitor still provides voltage until the end of the cooling cycle.
2.) Contactor –
Contactors are what controls the flow of electricity into your unit. When you turn off your AC the contactor blocks power, and when turned on it allows electricity through the system. Think of it like an electrical bouncer, it decides what goes into the system electrically and when.
3.) 220V High Voltage Line In –
The high voltage in is responsible for delivering the electricity into the connector. It takes current from a hardwired input, like a plug or direct wire and inputs it into the system in order to make it function.
4.) Load Out –
The load out is responsible for taking the electricity from the connector and distributing it to the fan, compressor, and other internal components. It takes the power from the high voltage line in and delivers it to the proper points in the system.
5.) Thermostat Wires –
These wires take input from the thermostat and communicate it to the air conditioner system to tell it what temperatures to operate to. It is how you are able to tell your AC what to do from your thermometer placed on the wall.
6.) Liquid Service Valve –
The liquid service valve is how HVAC techs are able to remove the refrigerant from your air conditioner, without needing to remove all of the refrigerant in the system. This allows the technician to also add small amounts of refrigerants in the event of a leak. Its third use is being used to measure refrigerant gas pressure in a system. This is how refrigerant is pushed into the system.
7.) Suction Service Valve –
The suction service valve can be used to isolate your compressor. Your compressor is where your refrigerant undergoes its cooling, and a majority of it can be located there. In the event of a refrigerant leak this valve can be used to lock off your AC unit from the rest of the system. This is how refrigerant is sucked through the system.
