How to Repair Compressor of AC?

I have been using my Aircon AC for the last few years and recently, it hasn’t been working properly. To learn about the issue, I hired an AC technician from NoBroker. He examined the AC and told me that the compressor of the AC had gone bad. Following this, I asked him if it could be repaired and, if yes, then how to repair AC compressor. 

How to Repair Aircon Compressor?

He told me that the compressor could be repaired but there is a chance that it might go bad in the future again. The best course of action according to him was to replace the compressor. To learn how to replace the compressor he asked me to follow him as he replaces it. Here is what he did. 

• He examined the AC again to check if there was anything else that needed repalacing other than the compressor. 

• As everything else seemed to be working properly, he started removing the AC compressor.

• He located the compressor belt on the front of the compressor and removed it by loosening it. 

• Next, he located all the electrical connectors on the compressor and unplugged them. 

• After that, he used a wench to disconnect the refrigerant lines of the compressor. He also capped these lines to restrict the contaminants from entering the system.

• Now, he removed the bolts and carefully removed the compressor. 

• After that, he installed the new compressor in the same position. Following this, he reattached the bolts, connected the refrigerant lines, plugged in the electrical connector, and finally, reattached the compressor belt. 

And that is how to repair air conditioner compressor, as performed by the AC technician. I hope this process helps. 

Hi there, I recently encountered a faulty compressor, because of which my AC stopped working. I called an AC technician who showed me how to repair air conditioner compressor. Well, he actually suggested I replace the compressor because it had broken down and there was no other alternative. So, let me take you through the process for the replacement.

How to Fix AC Compressor?

Here is how you can assess and repair your AC compressor. 

1. First, check whether the AC turns on normally or not.

2. Next, check the circuit breaker box switches. See whether the AC has power. Find the circuit breaker box, which is located on the outside of your home. 

3. Once you find the box, see if the circuit for the AC has its switch in the right order and place. 

4. After this, see the circuit breaker box for power to your AC. If you observe that the AC is not getting power, flip the breaker to the off position and then turn it back again.

5. Find the fuse box of your AC and make sure it is in a healthy state. 

6. Before you lift out the compressor, remove all the refrigerant lines. Carefully remove the orifice tube, receiver drier and the expansion valve.

7. Get rid of any dirt and dust present in the AC unit. 

8. Place in the new compressor, orifice tube, and the receiver drier.

As you must have observed, this is highly technical work, which should be done by a professional. So, instead of taking the job into your hands, call an expert.

A failed compressor can reduce an AC system's efficiency and increase the likelihood that it will completely fail. I suggest you shouldn’t try to address your air conditioners without having the necessary information, expertise, or skills. Let me guide you first on can AC compressor be repaired.

How to repair AC compressor?

1) Check for the circuit breaker

You must turn off the condensing unit of the air conditioning system before beginning any air conditioning repair. Find the circuit breaker, it's normally near the building's electric metre in the major electric system.

2) Remove the cover

You need to find and remove the compressor covering and electrical board. There must be wires accessing the condenser unit at the side where the electrical board is located. If the compressor cover of the device has a fan installed on it, you must properly remove the screws holding the cover in place. It must be done before rotating the cover to transfer it to the side of the device. This way you will know how to repair chiller compressor.

3) Check the compressor

You need to check into the condenser electrical box where the compressor capacitor is placed. Check for the compressor, which is a metal cylinder with a round or circular form with wire connections coming out of the top. You must change that cover with the exact same component if it has stretched or is leaking. This will assist you in how to repair compressor of AC.

4) Check the capacitance

You should activate the capacitance option on your multimeter and pull that out. In order to match the reading to the capacitor's capacitance value, connect the multimeter wire to each capacitor terminal. The multimeter measurement needs to hold steady at 10% of the capacitor value. If this isn't the situation, replace the capacitor piece and reconnect the condenser wires to the appropriate terminals.

5) Check wire connectors

You must check the wire connectors that are fastened to the compressor's terminals with good caution. Use a compressor terminal tool kit to repair damaged wire connectors if the terminals appear to be burned or if they don't hold the terminals. Strictly adhere to the method of wire connecting. Replace the terminal covering for the compressor once you're done. This is what you must know about how to repair window AC compressor.

Now you are aware of can AC compressor be repaired.
