Panasonic air conditioners are very common because they have not only a good set of functions, but also offer users a variety of automatically controlled systems. Their job is to finely clean the air, ionize it, and destroy viruses and dangerous bacteria.
The automatics can turn off the air conditioner if it needs cleaning or repairs. In this case, the device signals the occurrence of problems. In particular, the signal LED flashes, which means that it is necessary to read and decode the fault codes. This helps to understand what happened and how serious the problem is.
What malfunctions most often occur
The control automation that controls the indoor unit can give a signal and block the operation of the Panasonic air conditioner, not only when it needs repairs. The fact that the device does not turn on and the warning lamp is on or flashing may mean that cleaning of the air conditioner is required. panasonic... This situation occurs quite often, because:
- the indoor unit of some models (depending on the marking) is equipped with an E-Ion cleaning system. Its sensors monitor the state of the air, and in case of contamination, the generator of charged ions is turned on, killing mold and fungal spores. When the sensor shows acceptable air quality, the E-Ion system shuts down and a timer signals the problem. It is easy to understand that an alert can indicate both that the sensor or generator needs to be repaired, and that it is just time to clean the filters;
- the Air Purifying filtration system is also constantly monitored and any malfunctions in this structure, which fights against pathogenic bacteria, viruses and allergens, will cause the air conditioner to turn off. Often, you just need to disassemble, clean the filters, after which the device turns on again and works without interruptions.
Sometimes, when the control system determines that parts need to be replaced, the air conditioner shuts down by itself. This is a sure sign that major repairs are ahead. In this case, the control relay will block the activation of the device until the moment when the failed parts correspond to the passport parameters.
Careful care requirements
The instructions for the air conditioner describe the periodic maintenance procedures for the Panasonic product. This is a critical piece of documentation and should be studied as thoroughly as operating mode management.
Repairs and spare parts to restore functionality and troubleshoot can be very expensive. Therefore, care in compliance with all manufacturer's requirements is critical for Panasonic equipment.
Some maintenance procedures are not time-consuming, while others require partial disassembly of the indoor or outdoor unit, for which it is better to seek the help of a qualified technician.
How the faults of Panasonic climate systems differ
Problems and malfunctions of climatic technology, which are signaled by a timer and a blinking light, can be divided into large groups. A short list looks something like this:
- malfunctions in the air conditioning system;
- the device does not turn on, since a signal is received from control sensors, which record the exit of parameters from safe limits;
- blocking of work is caused by the indoor or outdoor unit;
- there are faults in the electronic control system.
Naturally, there are minor troubles when malfunctions will only cause minor repairs, for example, replacing a relay. But there are also difficult cases when a warning light means that the device will need to be disassembled and expensive parts replaced.
How to determine what happened and which malfunctions require intervention
If the air conditioner does not turn on and the signal lamp flashes, it is necessary to determine the nature of the malfunction. This requires reading and decoding the corresponding code, which is returned by the control system of the device. Error codes for panasonic air conditioners can be determined in the following ways, depending on the model marking and its design features:
- a device equipped with a screen displays the fault code by itself. In this case, the internal timer periodically starts repeated diagnostics;
- a model without a digital indicator and a test button on the remote control requires pressing the UP button on the timer setting panel, after which it is easy to read the error code on the indicator on the remote control. You just need to scroll through the list, if the block error coincides with the code on the remote control, the device will emit a sound signal;
- in the case when the control panel has a test button (it looks like a hole), it must be pressed and held. When the first error code appears on the screen, you need to scroll through the list. When the displayed error, the code of which is easy to understand, matches the contents in the memory of the unit, the air conditioner will emit a long beep or a series of short ones.
It is extremely rare, but there are problems when the control relay of the warning system fails and it is not possible to determine the error code of the unit and the spare parts to be replaced. In this case, you should immediately seek qualified help.
It should be remembered that the control and monitoring system is present in two parts of the air conditioner. Therefore, if a problem occurs, both indoor and outdoor units should be “interrogated” to determine the corresponding error code and required repairs.
Decoding error codes
Air cooling is a key function of the air conditioner, so the related systems and parts are under constant load and tightly controlled. Both passive sensors, relays and a system of periodic checks are used, the interval of which is controlled by an internal timer. Below are some error codes describing air conditioning system malfunctions.
H11 - the indoor and outdoor units cannot establish communication or the control does not work due to a malfunction in the electronic boards.
H12 - the outdoor unit does not have the appropriate capacity to work with the indoor unit.
H15 - malfunctions of the compressor temperature control sensor.
Н16 - malfunctions in the freon exchange system, manifested in the fact that the external unit consumes a small current. Another reason is an open circuit in the transformer or a malfunction of the IPM power module, disassembly is necessary. This test is controlled by a timer and is repeated continuously.
Decoding of codes responsible for sensor system malfunctions
Below are some codes showing breakage or failure of control devices, relays, sensors, which makes it impossible to control the air conditioner. A clear indication that replacement parts will be required.
H14 - air sensor.
H21 - float sensor.
Н51 - the relay of the AC Robot system, which is responsible for controlling the clogging of the nozzle, has been triggered.
Н52 - malfunctions of the limiter relay.
Н98 - the temperature relay has triggered, which controls the operating mode of the indoor unit when the air is heated, the signal indicates insufficient heat extraction.
A complete table of malfunctions includes several dozen codes; there is a separate list of industrial air conditioner malfunctions and their corresponding indications, which are generated by an internal timer.
Having correctly identified the malfunctions, you can clearly understand what parts will be needed, what repairs are to be done, whether the electronic control system needs intervention, or whether the signal markings indicate minor malfunctions. In general, you can give advice - if the timer light is on or flashing, you should call a qualified technician.
