Compressor capacitance detection
1. Appearance inspection: compressor capacitors are divided into dry type and oil-immersed type. Dry type capacitors are mostly encapsulated with plastic shell, while oil-immersed capacitors are encapsulated with metal shell. Replacement capacitors as far as possible is the original specifications, not optional replacement.


2. Capacity check: capacitor capacity will be attenuated due to harsh service environment and time extension. Generally, if the attenuation is more than 20%, it will be difficult to start, with large starting current and long starting time. Especially when the power supply voltage is lower than 20%, there will be a start stop, overcurrent protection, or even burn out the compressor. Therefore, when it is difficult to start, start time is too long, instantaneous jump stop phenomenon, the first to check the capacitor.


Measurement method:
a. measurement with digital multimeter capacitor or special capacitor;
b. Roughly measure the charging and discharging time with the resistance file of the pointer type multimeter: the red and black watch pens touch the capacitor poles respectively, and the watch needle rapidly rises and then slowly and quickly falls back to the original position, which is a good capacitor. If the watch needle does not rise or cannot return to the original position after rising, the capacitor is broken.
c. Start the test by comparing the old and new capacitors.
