What causes the air conditioner compressor not to work?

We always make sure to acquire The best types of air conditionersHowever, you will notice that there is a specific time in the summer when the temperature rises very high.

This is where air conditioner malfunctions begin to appear and increase day after day due to the continuous use of these air conditioners.

On the other hand, you'll find that there are some easy problems that you can handle yourself, including cleaning the air conditioner filter and other things. However, in the following lines, we'll learn about the reasons why the air conditioner compressor isn't working.

What is an air conditioner compressor?

The air conditioner compressor is one of the important parts of which air conditioners are composed, as the compressor is the part responsible for the cooling process. Therefore, in the event of any malfunction in it, all parts stop working.

It may be made up of interconnected elements that work together, or it may be one of the basic pieces, including:

• Capacitors: These are one of the components of the compressor and are often subject to failure.
• Starting relays: If the capacitors are working fine, the starting relays are likely faulty and should be replaced.
• Valves: If one of the valves is broken, you will find that the air conditioner continues to operate, but no cold air is coming out of it. In this case, the broken valve must be replaced with another one.
• Electrical connections: Most likely, all parts of the air conditioner will be fine and working properly, but one of the electrical wires may be cut, disconnected, or otherwise damaged, causing the air conditioner to stop working. The solution to this is to replace the wires.

What is the function of the air conditioner compressor?

A compressor is a component located on the high-pressure side of an air conditioning system that converts the refrigerant gas into a liquid when it passes through the condenser.

It also compresses the refrigerant gas, which makes it very hot. It is then passed to the condenser, which cools the gas until it turns into a liquid.

Then it is recirculated to the dryer receiver and expansion valve, and thus you find that the evaporator enters until it is exposed to heat from the air in the cabin and thus returns again to become a gas.

This cooling occurs through metal tubes and evaporator fins, delivering cool air to the cabin based on what the blower fan produces. Thus, it becomes clear to you that the compressor is an essential part of this process.

Reasons why the air conditioner compressor does not work

The reasons why the air conditioner compressor is not working are divided into two main points. One of them is related to the internal components of the compressor itself, and the other point is related to the electrical power and the connected wires. We will list them below:

• Damaged condenser: One of the reasons why an air conditioner compressor is not working is because it is damaged. The solution is to replace it.
• The thermostat is not in the cooling position: One of the most common reasons for this is that the air conditioner is not set to cool at a temperature lower than the room temperature, so you must make sure that it is set correctly.
• Damaged valves or valves: Damaged valves or valves may cause the air conditioner compressor to stop working or to work without any cooling.
• There is a problem with the electrical connections: they may have been moved, loose, etc.
• Insufficient lubricants: If the air conditioner lacks lubricants, this will result in several problems, including compressor failure.
• Dirty coils: Dirt or dust on the capacitor can cause increased pressure or heat inside it.
• Electrical problems: When there is an electrical failure, it results in the presence of a small amount of acid that will affect the entire air conditioning system, as well as the compressor.
• Compressor lifespan: There is a possibility that the reason the air conditioner compressor is not working is that its lifespan has expired, which ranges from 10 to 15 years.

The car's air conditioner compressor is not working.

There are undoubtedly some reasons why a car's air conditioner compressor may not be working, including the following:

• Higher than normal temperature: This is the most common cause, and there are approximately 3 reasons that cause a high temperature, including:
  • Low coolant level.
  • Coolant leak.
  • Compressor damage.
• Loud noise when the air conditioning system is running.
• Compressor clutch not moving.
• No electricity reaching the compressor.
• There is a break or blockage in the air conditioning pipes.
• There is damage to the electrical wiring.

The compressor starts and stops quickly.

There are reasons why the compressor starts and stops quickly, including:

The thermostat may not be working properly, as it is a small device that adjusts the temperature and stops the compressor at a specific time.

Or there may be a fault in the electrical terminals: This is because the compressor operates via electrical terminals.

Another reason that can cause the compressor to start and stop quickly is a weak electrical current. This is because the current is generated by the battery that powers the compressor, or a fault in the compressor's capacitor.

Why the air conditioner does not work

There are many reasons why the air conditioner does not work, including the following:

Power outages.

• The outside temperature is high.
• Small air conditioner size.
• Thermostat fault.
• There may be a blockage in the internal air filter.
• Low refrigerant level.
• Compressor failure.
• Dirty condenser coils.

How to check the split compressor

The ohmmeter leads are connected between C + R and the number is recorded, most often it will be 002.

Then connect the ohmmeter leads between C + S and write down the number. Normally you will find it is 005.

The ohmmeter terminals are connected between R + S and you will find it is 007 and this is the sum of the number or value of the ohmmeter between C + R, C + S.

Central air conditioning compressor

You'll notice that central air conditioning compressors vary in price from one type to another. There are several types, including Bec air conditioners, vertical air conditioners, central air conditioners, hermetically sealed compressors, semi-hermetic compressors, rotary compressors, reciprocating compressors, and other types.

Split air conditioner compressor repair

When repairing a split air conditioner compressor, all parts of the unit must be in good condition, but the focus should be on the air conditioner compressor.

Without it, it will not function properly. You can repair the split air conditioner compressor by following these steps:

• The circuit breaker is checked to make sure it is working properly.
• Make sure the air conditioning unit is blowing cold air while operating.
• Verify that the thermostat is a programmable program.
• If there is a fault in one of them, it must be repaired.

You cannot bear the high temperature especially when you are working or at home especially in summer.

Here you will notice that the air conditioner may suddenly stop working over time, which makes you search for the reasons why the air conditioner compressor is not working, which we explained in the previous lines.
