How to Fix a Broken Power Inverter How to Fix a Broken Power Inverter
If you ever use an RV or go camping, or maybe you even live in area with DC (direct currents) and you need AC (alternating currents), you will need to use a power inverter. If you use this device a lot, if it is older or you want to make it more efficient, read on to learn how to make repairs or improvements.
Though you likely already know this, always turn it off and unplug it before working on anything dealing with electricity. You may also want to use an anti-static electricity band to help keep you and the power inverter grounded. You can buy one at almost any technology/electronic goods store.
Diagnosing the Issue
Before you can diagnose the problem, you should learn how a power inverter works. Inside the inverter is a switch that houses two contact points. These contact points have a spring based contact between them, that oscillates among the two contact points. When plug-in to an electrical source, the electromagnets move the contact between the two points, back and forth.
Now that you know how it works, it should be easier to diagnose the problem. Find a diagram of the power inverter and use that as a reference to know what is what and where they are. You should start by checking the spring contact and the contact points. If they appear to be fine, check rest of the components in the inverter. You may need a voltmeter to test them, be sure to follow the guidelines and follow any safety precautions they advise.
Order Replacement Parts
Once you know what part is defective, you can order the newer parts in to make the repairs. Make sure they will fit and are at the right voltage for the power inverter. Otherwise it could blow it out or not fit in the sockets. You can order most parts online, the prices will depend on where and how you order. So be sure to do your research before ordering.
Once you have received the parts, the real work can begin. You will need to remove the older and non-working parts from the inverter. Be careful and try not to handle them roughly, because that could damage rest of the power inverter working components. Some parts will simply plug-in, while most will need to be soldered in.
When soldering in parts, be careful and again follow any safety precautions the manufacture advises you to follow.
When you are finished soldering or installing the new parts, while it still is open run a test. Make sure that the area is clear of any lose parts or debris. Also, when doing the test run, plug it in a limited power source. Like a power supply or lamp. Use a voltmeter to read the voltage to make sure it works.
If so, then you can put it back together. If it does not work, go back over these steps.
Remember to follow any safety guidelines and always have it unplugged before you begin to work on it.
