How to judge the good or bad of Compressor Capacitor?
Using instrumentation, testing. Or with experience directly with the test machine (detection of the replacement capacitor), the problem is that the capacitor is broken.
1. to see whether the expansion of the shape (drum up), whether there is no leakage2., with multimeter, the number of capacitive file micro method, compared to the tag tag capacitor3. with pointer (such as type 500), multimeter, resistor, capacitance, open circuit or short circuit, all proved to be broken. A good capacitor pointer will show the charge and discharge process and will clearly see a sharp shake.
