Panasonic air conditioners are very common, because they have not only a good set of functions, but also offer users a lot of automatically controlled systems. Their work is to fine-tune the air, its ionization, as well as the destruction of viruses and dangerous bacteria.
Automation can turn off the air conditioner if it needs to be cleaned or repaired. In this case, the device signals a problem. In particular, the alarm LED flashes, which means that it is necessary to read and decode the trouble codes. This helps to understand what happened and how serious the problem is.
What malfunctions most often arise
Automation controls that control the indoor unit can give a signal and block the operation of the Panasonic air conditioner, not only when it needs repair. The fact that the device does not turn on and the indicator light is on or flashing may mean that the air conditioner needs cleaning panasonic. This situation arises 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, with pollution, the generator of charged ions that kill mold and fungal spores is turned on. When the sensor indicates acceptable air quality, the E-Ion system shuts down and a timer signals a problem. It is easy to understand that an alert can indicate that repair of the sensor or generator is necessary, and that it is just time to clean the filters;
- The Air Purifying filtration system is also under constant control and any malfunctions in this structure that fights pathogenic bacteria, viruses and allergens cause the air conditioner to turn off. Often, just disassembling, cleaning the filters is required, after which the device turns on again and works without failures.
Sometimes, when the control system determines that the parts need to be replaced, the air conditioner switches itself off. This is a sure sign that a serious repair is ahead. The control relay will block the inclusion of the device until the moment when the failed parts correspond to the passport parameters.
Care Requirements
The instructions for the air conditioner describe procedures for periodic care of a Panasonic product. This is a critical piece of documentation that needs to be studied as carefully as mode control.
Repair and parts to restore performance and troubleshoot can be very expensive. Therefore, care in compliance with all manufacturer's requirements is crucial for Panasonic equipment.
Some maintenance procedures do not take a lot of time, but for others it is necessary to partially disassemble the internal or external unit, for which it is better to use the help of a qualified specialist.
How malfunctions of Panasonic climate systems differ
The problems and malfunctions of the climate technology, which are signaled by a timer and a flashing 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 that record the output of parameters from safe limits;
- operation blocking is caused by an indoor or outdoor unit;
- There are malfunctions in the electronic control system.
Naturally, there are minor troubles when malfunctions cause only minor repairs, for example, replacing the relay.But there are also difficult cases when the signal light means that the device will need to be disassembled and replaced with expensive parts.
How to determine what happened and what malfunctions require intervention
If the air conditioner does not turn on and the warning light flashes, it is necessary to determine the nature of the malfunction. This requires reading and decoding the corresponding code that the device control system returns. The error codes of panasonic air conditioners can be determined in the following ways, depending on the marking of the model and its design features:
- a device equipped with a screen displays the fault code on its own. In this case, the internal timer periodically starts re-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 parse the error code on the remote control on the indicator. You just need to scroll through the list, if the block error coincides with the code on the remote, the device will emit a sound signal;
- in case there is a check button on the control panel (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 parse, matches the contents in the unit's memory, 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 unit error code 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 there are malfunctions, you should “interrogate” both the indoor and outdoor units and determine the corresponding error code and the required repair.
Decoding Error Codes
Air cooling is a key function of the air conditioner, therefore the corresponding systems and spare parts are under constant load and are 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 that describe air conditioning malfunctions.
H11 - the internal and external units cannot communicate or control does not work due to a malfunction in the electronic circuit boards.
H12 - the outdoor unit does not have the appropriate power to work with the indoor.
Н15 - malfunctions of the compressor temperature control sensor.
H16 - malfunctions in the Freon exchange system, manifested in the fact that the external unit consumes low current. Another reason is an open circuit in the transformer or a malfunction of the IPM power module, disassembly is necessary. This check is controlled by a timer; it is repeated continuously.
Decoding codes for sensor system malfunctions
Below are some codes that indicate the breakdown or failure of control devices, relays, sensors, which makes controlling the air conditioner impossible. A clear sign that replacement parts are required.
H14 - air sensor.
H21 - float sensor.
Н51 - the AC Robot system relay was activated, which is responsible for controlling the nozzle blockage.
H52 - limiter relay malfunctions.
Н98 - the temperature relay has tripped, which controls the operation mode of the indoor unit when the air is heated, the signal indicates insufficient heat removal.
A complete table of faults includes several dozen codes, there is a separate list of faults of industrial air conditioners and their corresponding indications, which form an internal timer.
Having correctly identified the malfunctions, you can clearly understand which spare parts will be needed, what repairs are to be done, whether the electronic control system needs intervention, or if signal markings indicate minor malfunctions. In general, you can give advice - if the timer lamp is on or blinking, you should call a qualified master.
