It may be irritating, not to mention costly, to cope with a defective air con compressor. Fortunately, there are methods to check your compressor and decide if it is really malfunctioning. Whether or not you are a seasoned DIYer or an entire novice, understanding how one can check an AC compressor can prevent time, vitality, and cash in the long term. Let’s dive in and discover the easy but efficient strategies for diagnosing your compressor’s well being.
Earlier than embarking on any testing process, security must be your prime precedence. Be certain that the ability to your AC unit is totally turned off on the breaker or fuse field. Moreover, it is advisable to put on gloves and security glasses to reduce the danger {of electrical} shock or damage from sharp edges. With these precautions in place, you’ll be able to proceed with confidence, figuring out that you take the mandatory steps to guard your self.
To start the testing course of, you will want a multimeter, a standard device used for electrical measurements. Set the multimeter to the AC voltage setting and join the probes to the terminals on the compressor. With energy restored to the unit, observe the voltage studying on the multimeter. A correctly functioning compressor will sometimes show a voltage studying inside a particular vary, normally between 110 and 125 volts. If the voltage studying falls exterior this vary, it might point out an issue with the compressor or different electrical parts within the AC system. Nevertheless, it is necessary to seek the advice of your particular AC unit’s guide for the precise voltage specs.
The way to Take a look at an AC Compressor
An AC compressor is an important a part of an air con system. It compresses refrigerant fuel, which will increase its strain and temperature. The compressed fuel is then despatched to the condenser, the place it condenses right into a liquid. The liquid refrigerant then flows to the evaporator, the place it evaporates and absorbs warmth from the air. The cooled air is then blown into the room or constructing.
If the AC compressor shouldn’t be working correctly, the air con system will be unable to chill the air successfully. There are a number of other ways to check an AC compressor to see whether it is working correctly.
Instruments and supplies wanted:
- Multimeter
- Refrigerant gauge set
- Wrenches
- Screwdriver
Steps:
- Verify the ability provide to the compressor. Be sure that the circuit breaker or fuse shouldn’t be tripped or blown.
- Verify the capacitor. The capacitor is a small, cylindrical machine that’s linked to the compressor. It shops electrical vitality and helps the compressor to start out. If the capacitor is defective, the compressor will be unable to start out.
- Verify the refrigerant strain. The refrigerant strain must be inside a sure vary. If the strain is simply too low, the compressor might not be capable of compress the refrigerant correctly. If the strain is simply too excessive, the compressor could also be overloaded and should fail.
- Verify the compressor’s amperage draw. The amperage draw must be inside a sure vary. If the amperage draw is simply too excessive, the compressor could also be overloaded and should fail. If the amperage draw is simply too low, the compressor might not be capable of compress the refrigerant correctly.
In case you are undecided how one can check an AC compressor, it’s best to name a professional technician. A technician can check the compressor and guarantee that it’s working correctly.

What are the signs of a foul AC compressor?
There are a number of completely different signs which will point out that your AC compressor is dangerous. These signs embody:
- The AC unit shouldn’t be cooling the air successfully.
- The AC unit is making a loud noise.
- The AC unit is leaking refrigerant.
- The AC unit is tripping the circuit breaker or blowing the fuse.
How a lot does it value to interchange an AC compressor?
The associated fee to interchange an AC compressor will fluctuate relying on the make and mannequin of your AC unit, in addition to the labor prices in your space. Nevertheless, you’ll be able to count on to pay between $800 and $1,500 for a brand new compressor.
Can I change an AC compressor myself?
It’s attainable to interchange an AC compressor your self, however it’s not a easy job. In the event you wouldn’t have expertise working with electrical and refrigerant programs, it’s best to name a professional technician to interchange the compressor for you.
