Presence Of Lose Clips Or Screws
Just like any other electrical component, the inverter also has a number of screws. Basically, these screws help in fastening the internal components of the inverter. In case these screws are loose, chances are that you will hear an inverter noise anytime it is in operation. Besides loose screws, broken clips can make your inverter to be noisy.
Damaged Inverter Part
In case there is a damaged component in your inverter, be certain you will hear an inverter noise whenever the model is in use. If you are the victim of this circumstance, you might need to seek the help of a professional technician so as to avert this problem.
A Failed Inverter’s Self-Test
Most inverters usually perform a self-test after every 2 weeks. Ideally, this test is done in order to check your battery’s integrity. Although there are instances when the test goes on smoothly, there are moments it might fail.
Suppose the inverter fails this test, it shows that your battery is dead and needs to be replaced as soon as possible. If this happens, your inverter will start to make a beeping noise after every 4 to 5 hours.
Other Reasons Why Your Inverter Might Start Clicking Bring Inverter Noise:
Apart from the reasons that we have discussed above, here are other additional reasons why your inverter is producing a clicking sound:
- Your inverter’s motor has burned out.
- Your inverter has a loose wire inside it.
- Presence of a damaged cable.
- You have placed your inverter in a place that has poor ventilation.
- Your inverter has old or bad capacitors.
How Do I Stop My Inverter From Making Noise?
Since you already know the various reasons why you are experiencing inverter noise, time is ripe for you to know the various methods that can help keep this noise at bay. Some of the ideas that can help you get started include:
Things to Check to Stop Inverter Noise
Do Not Overload Your Inverter
