Panasonic Air-conditioning Error e04

What does this problem mean that the Panasonic air conditioner has?

Oh no! The hot and summer season has arrived and your air conditioner is showing an error code that you simply don't know what it could mean. It's time to understand what we are facing, so you can enjoy the cold this season and forget about the heat once and for all.

As we all know, the air conditioner allows us to have a pleasant temperature in our home and at our workplace. The error code e04 in Panasonic air conditioners indicates that there is a problem with the temperature sensor, and it may be short-circuited.

In this article, we will explain what this error code might mean, what its possible causes are, and how to solve it simply and effectively. This way, you can avoid major damage to your equipment and save time and money on repairs.

The temperature sensor of the indoor module is responsible for measuring the air temperature that enters and exits the unit. This information is sent to the controller to regulate the operation of the compressor and the fan. If this sensor fails or does not receive the correct signal, it can cause this type of error to appear on the screen of the indoor split unit. This failure can have different causes, including:

• The sensor is dirty or damaged: Dust, moisture, or some impact can affect the sensor and make it malfunction. This can alter the temperature reading and cause the failure.
• The wiring is loose or cut: The sensor connects to the PCB electronic board via cables that can become loose or cut for some reason. This prevents communication between the two components and generates this type of error in your air conditioner.
• Failure in the PCB electronic board: The control board is the brain of the air conditioner and is responsible for processing the information received from the sensor and sending commands to the compressor and the fan. If the board is defective, it could misinterpret the sensor's signal or not send the correct commands.

These are the causes that make this failure appear on the screen of your Panasonic air conditioner. But don't worry, let's see what solutions you can apply yourself so that we can fix this problem together.

How could I fix the error code e04 of the Panasonic air conditioner?

The good news about this problem is that you don't have to endure the heat this summer season and you can reactivate your air conditioner if you follow our advice to the letter. Don't skip any of the steps we will leave you below:

1. Restart the air conditioner to help reset the sensors: Sometimes, a simple restart can solve the problem as this resets the sensors. To perform this simple procedure, you need to completely turn off your air conditioner using the remote control, unplug it from the electrical outlet, and wait a few minutes. Then, plug it back in and turn it on again to see if the error has disappeared. If the error persists, you will need to follow the steps we leave you below.
2. Check and clean the temperature sensor of your Panasonic air conditioner: Perform preventive maintenance on your air conditioner to clean this temperature sensor. If the sensor is dirty, you can clean it using an electronic cleaner and a cloth dampened with this liquid. If you have knowledge in electronics and have a multimeter, take the opportunity to check if this sensor is working correctly. After cleaning it and verifying its operation, put it back in its position, connect it, and turn on the air conditioner to check if the error has disappeared.
3. Check the temperature sensor wiring and your air conditioner in general: If the wiring is loose, cut, or burnt, you can try to connect it properly or replace it with a new one. To do this, you will need to open the cover of the indoor module (split) with a screwdriver and locate the cables that go from the sensor to the PCB electronic board. Make sure to unplug the equipment from the electrical outlet before handling the cables to avoid shocks. Once you have fixed the wiring, turn on the air conditioner and check if the error code has disappeared.
4. Replace the temperature sensor if you notice it is not working well: Check your sensor again with a multimeter and verify if it has continuity and is working correctly. You will need to have knowledge in electronics to do this yourself, and if the sensor is damaged, you will need to replace it with a new one. After replacing the sensor, turn on the air conditioner and check if the error has disappeared.
5. Check the PCB electronic board and replace it if necessary: Inspect the components of the PCB board that controls all the functions of your air conditioner. Verify that these components have good continuity on the multimeter, or otherwise, you will need to locate the replacement part and replace it or change the PCB electronic board entirely. After replacing the PCB board, turn on the air conditioner and check if the error has been resolved.
6. Review all the steps we have described above to rule out omitted details: If after performing all the previous steps, the error still appears on your Panasonic air conditioner, there may be another damaged component or the problem may be more complex than it seems. In that case, we recommend that you repeat all the previous steps with more care and attention to ensure that you did not miss any detail or that you have not omitted any of the previously mentioned steps.
7. You can contact Panasonic technical support to solve this problem: If after repeating all the previous steps the error still appears, it is most likely that you need the help of a qualified professional. And who better than the Panasonic service technicians? The manufacturer itself will provide you with a service you can rely on in these cases. You lose nothing by giving them a call and requesting a service, especially if the equipment is still under warranty. Let's go!

In summary, the error code e04 in Panasonic air conditioners is a problem related to the temperature sensor. This problem can be caused by different factors, such as a general failure in the temperature sensor, problems with the internal wiring of the air conditioner, or a PCB electronic board with some defective components. To find a solution to this problem, you need to follow all the steps we have detailed for you.

That's all for today! A fault that may not be very complicated to fix, especially if you follow everything we have mentioned above. Perhaps what your temperature sensor or your air conditioner needs is a general preventive maintenance and that's it. Good luck!
