If your ac compressor won’t come on, one of the possible culprits could be a faulty capacitor. The capacitor serves as a starting device for the compressor, providing the necessary jolt of electricity to get it going. If the capacitor is damaged or worn out, it won’t be able to do its job effectively, and your compressor won’t be able to start up.
Fortunately, checking the capacitor is a relatively simple process that you can do yourself. First, turn off the power to your AC and locate the capacitor, which is usually a shiny cylinder or oval with wires attached. Use a multimeter to check the continuity of the capacitor, as this will indicate if it’s still functioning properly.
If the multimeter shows no continuity, you’ll need to replace the capacitor. It’s important to note that working on your AC requires knowledge and caution, so if you’re unsure or uncomfortable performing this task, it’s best to call a professional.
Test the capacitor with a multimeter to confirm it is functioning properly
If you suspect that your capacitor is not functioning properly, the first step is to check whether it is still working by using a multimeter. A capacitor is an essential component of any electrical device, and it stores electrical energy, so it’s crucial that it’s in good condition. To check if it’s working, you need to set your multimeter to measure capacitance and then connect the test leads to the capacitor’s terminals.
If the multimeter reading shows values that are similar to the capacitor’s rating, then it’s a good sign that your capacitor is functioning correctly. If the values differ significantly, it may indicate a fault in the capacitor, and you may need to replace it. In conclusion, always test your capacitor with a multimeter to ensure it’s in proper working condition.
Don’t risk damaging other components by neglecting this crucial step.
Examine the Relay Switch
If your AC compressor wont come on, one possible issue could be a faulty relay switch. The relay is responsible for switching on and off the power supply to the compressor. You can examine the relay switch by checking for any signs of damage or wear and tear on the wires or connections.
Another thing to check is the voltage going to the relay switch to ensure that it’s receiving the correct amount of power. If the relay is not working correctly, it could be replaced or repaired. This is a job that should be done by a professional, as it requires specialized knowledge and equipment.
Replacing a relay switch can be a relatively quick and straightforward fix for an AC compressor that won’t come on, but it’s best to consult with an expert to ensure that you don’t cause any further damage to your system.
