WINDOW AIR CONDITIONERS
About Lesson

To test the electrical connections of a window air conditioner, tools such as a multimeter, clamp meter, voltage tester, and insulation resistance tester are used. These tools check the continuity, voltage, current, and insulation of key components like the compressor, fan motor, capacitor, thermostat, and control board. Testing methods include measuring the resistance of motor windings, checking the capacitor’s functionality, verifying the thermostat’s operation, and ensuring proper power supply connections. Continuity tests confirm complete electrical paths, while voltage and current tests ensure that components are receiving the correct power. Proper testing helps diagnose electrical issues and ensures the unit operates safely.
