How to fix air conditioner short cycling? Have you ever experienced your AC suddenly turning on and off repeatedly?

Well, if your AC often turns on and off quickly or even repeatedly without a clear cycle, then your AC may have a malfunction called short cycling.

This can be caused by a few reasons, such as clogged air filter, low refrigerant level, or even failing compressor.

How to Fix Air Conditioner Short Cycling?

1. Check the Electrical Power Supply

The first thing you can do is to check the power supply.

Sometimes, a simple problem like a loose cable can cause the AC to turn off. Therefore, checking the power supply is the first step to identify and fix the problem.

Make sure the circuit switch or circuit breaker for your AC unit is not in the off position. If so, press the switch or reset the circuit breaker to restore the power supply.

After that, you can check the power cord connected to the AC unit and make sure the cord is not unplugged from the outlet or the AC unit itself. If there is a loose cord, reconnect it properly.

If you have an electrical tester, use it to check if the outlet where the AC is connected is still supplying electricity.

Check the power switch by making sure it is in the “on” position.

2. Fix the Thermostat Settings

The second way you can try is to fix the thermostat settings.

The thermostat plays an important role in controlling the desired room temperature. Sometimes, a mismatch in the settings on the thermostat can cause the AC to short-cycle. Here’s how to fix it:

Check the temperature setting on the thermostat, if it is at the desired level. Sometimes, setting the temperature too high or too low can cause the AC compressor to turn off.
Next, make sure your AC thermostat is set to the correct operating mode, such as cooling mode, and also check that it is not in “off” mode.
Try to reset the thermostat by turning it off first, then back on after a while. This can help restore any incorrect settings on the thermostat.
Clean the thermostat with a soft brush or low-pressure vacuum cleaner to keep the area around the thermostat free of dust and dirt that can interfere with the performance of the AC compressor.
If your AC thermostat uses a battery, make sure to check whether the battery has run out or not. Replace the batteries if necessary to ensure the thermostat is working properly.

3. Fix the Condenser that Might be Faulty

The third way to solve the problem of the AC short cycle is to check and repair the damaged AC condenser.

Why does the AC turn itself on and off and the lights flicker? One of the reasons could be a faulty condenser that causes the system to shut down. Here’s how to fix it:

Start by visually inspecting the condenser to see if there are any signs of physical damage such as cracks, breaks, or loose parts. If found, make repairs or replacements as needed.
A dirty condenser, or one that is blocked by dust and dirt, can impede the airflow needed to dissipate heat. Use a soft brush to clean the AC condenser.
Check the condenser fan, if the fan is damaged or stops spinning it can cause the AC condenser to overheat and cause the AC to short cycle. If necessary, replace the AC condenser with a new one.
Make sure that the condenser is properly mounted on its foundation or platform and that no components are loose or detached.

4. Clean the Air Filter

Another important way to solve the problem is to clean the air filter. The air filter in an air conditioner serves to filter dirt, dust, and other particles from the air entering the unit.

If the air filter is dirty or clogged, it can impede the airflow needed to keep the AC compressor functioning properly.

Start by turning off the AC unit and locating the air filter, then carefully remove the air filter from its holder.
Inspect the air filter to see if there is any dirt, dust, or other particles stuck to its surface. If the filter looks very dirty or clogged, this is a sign that it needs to be cleaned or replaced.
Use a soft brush to clean the surface of the air filter. You can also wash the filter with clean water if the filter is made of waterproof material.
If the air filter is too dirty or clogged and impossible to clean, it is better to replace it with a new one.

5. Check the Refrigerant Level

If you’re wondering why your AC compressor suddenly shuts off? Another possible cause could be a low refrigerant level that prevents the system from producing effective cooling.

Therefore, checking and recharging the refrigerant is an important step to keep your AC performing effectively. Here’s how to check the refrigerant:

Check the refrigerant level by using a pressure gauge. Make sure that the refrigerant level is within the range recommended by the AC manufacturer.
Check the AC system for signs of refrigerant leaks such as liquid trails or spots around the unit. A refrigerant leak could be the cause of the low refrigerant level and should be repaired immediately.
If a low refrigerant level is found, you can recharge the refrigerant. Make sure to follow the correct guidelines and procedures to recharge the refrigerant safely.
Perform regular checks on the refrigerant level periodically to help prevent AC compressor shutdown issues caused by low refrigerant.

But did you know that the AC needs to be certified before being sold and distributed in Indonesia?

Yup, the AC is one of the many products that are mandatory to be certified by the SNI certification.

This is because the risk of an air conditioner might be concerning for the Indonesian consumers, as the air conditioner that is not properly manufactured can cause a failure and can even be dangerous for its users.

The air conditioner that is about to be distributed in Indonesia must undergo a series of tests to determine its quality and safety.

After all of those tests have passed and the air conditioner is met with the requirements that have been set, the air conditioner is ready to be distributed and sold in the Indonesian market.

For the air conditioner and other household electrical devices, the regulation is clearly stated in SNI IEC 19-6713-2002.
