Air conditioning compressor jitter not refrigeration, is air conditioning capacitor is broken

Air conditioning separate-bodied air-conditioners capacitance to know it has started, must not look down upon it, if your air conditioning capacitor is broken after the refrigeration, air conditioner will not say that this is caused by air conditioning is not cooling or heating of the most common fault. The following is to introduce you to what are the symptoms of air conditioner condenser is broken.

there are two capacitance in the outdoor electrical and mechanical loading, bulky for compressor capacitor, electric mechanical and electrical capacity, small volume for the damage of different capacitance failure phenomena are also different:

1, compressor capacitor damage: performance phenomenon as normal compressor can have bigger noise and jitter, if the capacitor is damaged, hand in of the shell will feel on the top of the compressor compressor has a slight shake, sounds like a current through the sound, after a period of time the compressor shut down.

2, electric mechanical and electrical damage: performance phenomenon for compressor normal work after a period of time inside machine to stop working, and if there is a fault code will appear high pressure protection, compressor exhaust temperature protection.

how to detect the stand or fall of capacitance

1, connected directly with 220 v ac, we can pick up a pole, with another power cord touch another capacitance feet. In touch to see if there are obvious small spark, is certainly the capacitance charging, that is to say, the capacitance not bad.

2, pointer multimeter, also can use the digital meter capacitance measurement file. If use pointer multimeter, general use R & times; 1 k file, pens and capacitance of the poles is connected respectively. Multimeter pointer will swing at this moment, then slowly back to zero or near zero. The capacitor is good. The greater the capacity of capacitor, the longer the charge time, pointer swing in the direction to 00 also slower. If, after connect a pointer still shows very little resistance does not move, you can be sure is bad.

3, digital multimeter, use digital multimeter to check, to set the digital multimeter to the appropriate resistance, pens and red and the black pens and contact the capacitor being measured respectively the poles. At this point, the display value increase gradually starting from 0, indicating excessive symbol & other; 1' 。 If always show 0, internal short circuit capacitor. If always show overflow, may be internal capacitor electrode open, may also be a choice of resistance is not appropriate.

summary: on what are the symptoms of air conditioner condenser is broken relevant content to this, the first thing to understand symptom, so you know what kind of way to solve is better. Hope the above is introduced to be of service.

Many of us have heard about air conditioner capacitor and seen some of these units in operation in start capacitor suppliers, start capacitor suppliers and start capacitor suppliers spaces.

Hangzhou E cool refrigeration Co.,Ltd’s core aim is to afford high-quality products with the concept of manufacturing technology.

Along the way, Hangzhou E cool refrigeration Co.,Ltd will face a wide range of challenges. The most successful will show our resolve by working through the challenges and finding ways to improve and grow.

If we avoid overselling refrigerant gas start capacitor suppliers and capabilities, you gain credibility and earn trust. We did not want to jeopardize our ingrained preference for humility.

comes in a vast array of styles and start capacitor suppliers depending on which start capacitor suppliersis used.
