Why Are the Lights Flashing?

When the operation and timer lights flash 10 times, it means there is an error. The air conditioner is trying to tell you something is wrong. It is important to find out what the problem is. This will help you fix it quickly.

Common Causes

There are a few common reasons for the lights to flash. Here are some of them:

• Dirty Air Filter: The air filter might be dirty. This can block the airflow.
• Low Refrigerant: The refrigerant level might be low. This can cause the unit to not cool properly.
• Sensor Issues: There could be a problem with the sensors. This can make the unit act strangely.
• Electrical Problems: There might be an issue with the electrical components. This can cause the unit to not work correctly.

Steps to Fix the Issue

Here are some steps you can take to fix the problem. Follow these steps one by one.

Step 1: Check The Air Filter

The air filter is an important part of the air conditioner. It helps keep the air clean. If it is dirty, it can cause problems. Here is how you can check the air filter:

1. Turn off the air conditioner.
2. Open the front panel.
3. Remove the air filter.
4. Look at the filter. Is it dirty?
5. If it is dirty, clean it. You can use a vacuum or wash it with water. Let it dry before putting it back.
6. Put the filter back in the unit.
7. Close the front panel.
8. Turn the air conditioner back on.

If the lights stop flashing, the problem was the dirty filter. If not, go to the next step.

Step 2: Check The Refrigerant Level

Low refrigerant can cause the air conditioner to not cool properly. You might need a professional to check the refrigerant level. But here is how you can tell if the refrigerant is low:

• The air conditioner is not cooling as well as before.
• You hear a hissing or bubbling sound.
• There is ice on the refrigerant lines.

If you think the refrigerant is low, call a professional. They can add more refrigerant and fix any leaks.

Step 3: Check The Sensors

Sensors help the air conditioner work properly. If there is a problem with the sensors, the unit might act strangely. Here is how you can check the sensors:

1. Turn off the air conditioner.
2. Open the front panel.
3. Look for the sensors. They are usually near the air filter.
4. Make sure the sensors are clean and not damaged.
5. Close the front panel.
6. Turn the air conditioner back on.

If the lights stop flashing, the problem was the sensors. If not, go to the next step.

Step 4: Check The Electrical Components

Electrical problems can cause the air conditioner to not work correctly. Here is how you can check the electrical components:

1. Turn off the air conditioner.
2. Check the power cord. Make sure it is not damaged.
3. Check the circuit breaker. Make sure it is not tripped.
4. If you find any problems, fix them or call a professional.

If the lights stop flashing, the problem was the electrical components. If not, it is best to call a professional. They can help you find and fix the problem.
