What to do if, after the power supply, the device does not turn on and no error codes of the conditioner:

  • Make sure the integrity of the fuse;
  • Make sure the air conditioner serves 220 volts. If there is no power transformer on the primary winding, you should change the internal module fee. If the voltage is normal, you should check the secondary winding. With a positive result, it is necessary to change the internal module fee. With a negative to make sure that there are 14.5 volts at the output of the transformer. With a negative response, a transformer should be changed.

If after powering the indicator, the operation is disabled, the timer indicator blinks:

  • Put another control board. If it does not help, you should change the internal module fee. If it helped, then the current voltage is low.

Instructions to the control panel and air conditioners Lessar

To configure the operation of the climate equipment of this brand, a remote control for Lessar. It can be wired, wireless or central and differ in the number of functions, design or quality assembly.

In most cases, the instruction to the Lessar air conditioners in their composition already has a full description of the buttons. However, if for any reason it was absent in the complete supply of the air conditioner, you can read it with it.

Cassette air conditioner lesser error codes

The following reasons arising in the case when the air conditioner compressor does not work, are indicated from the most likely to the least probable. Check or test every reason since most likely reasons.

cassette, conditioner, lesser, error

Cause 1 Temperature Control Thermostat

The temperature control thermostat has inside electrical contacts, which over time burn out. In this case, the thermostat may continue to include the fan motor, but not the compressor engine.

Cause 2 Temperature Control Panel

Temperature control board gives a current on the fan engine and compressor. If the control board is faulty, it may stop supplying the current to the compressor. Control panels are often mistakenly diagnosed, so before it is replaced, make sure that you checked increasingly breaking parts, in particular, the compressor fuse, the condenser and the compressor itself. If you are sure that all other components work correctly, then replace the temperature control fee.

Thermostat controls air temperature. When the air temperature rises above the specified value, the thermostat activates the switch to ensure the flow of the current onto the fan and the compressor. If the thermostat is faulty, it may interfere with the compressor work. If you have determined the compressor malfunction, then replace it.

Cause 4 fuse

The fuse protects the compressor from the brave if it consumes too much current. Over time, the fuse can overcome. To determine whether the fuse burned, use the multimeter to check its continuity. If the continuity of the fuse is broken. Replace it.

The compressor itself can also be faulty, but it happens rarely. Before replacing the compressor, be sure to check more often broken components, in particular, the fuse and the compressor condenser. If the compressor is faulty, it can only be replaced by a licensed master.

Termistor. This is a sensor connected to the control board, which determines the air temperature. If the thermistor is faulty, it may interfere with the compressor work. To determine whether the thermistor is defective, use the multimeter by checking it on continuity. If the continuity of the thermistor is broken, then replace it.

The relay board provides voltage for many air conditioning components, including compressor. If the relay board works incorrectly, the compressor may not work from this. Relay cards are often mistakenly diagnosed; So before replacing the board, make sure that you checked all the details that break more often, especially the fuse, the condenser and the compressor itself. If you are sure that all other components work correctly, then replace the relay fee.

Cause 8 Home Management Board

The main management board controls the flow of current to all components of the air conditioner. If a problem arose with the control board, then it may stop supplying the current to the compressor. Control boards are often mistakenly diagnosed; So before replacing the main control board, make sure that you checked increasingly breaking parts, namely the fuse, the condenser and the compressor itself. If you are confident that all other components work correctly, replace the main management fee.

The condenser is connected to the compressor using electrical wires. If the condenser has blown, then the compressor will not work. To determine if the condenser has blown up, use the multimeter to check for continuity. If the continuity of the condenser is broken. Replace it.

Cause 10 Selector Switch

Selector switch gives a voltage to the compressor. If the selector switch is faulty, then the compressor will not work. First check the condenser, the fuse and the compressor itself. If none of these parts are damaged, the switch can be faulty. If the compressor works with interruptions when you press the buttons on the switch or turn the switch knob, then replace the selector switch.

Error ELECTROLUX. Code Decryption Rules

Air conditioners error codes are service information related to software varieties. It is brought into the air conditioner control unit by the so-called “firmware” method.

The decoding of air conditioners is important not only for specialists, but also for users.

Any error code ELECTROLUX allows you to instantly determine the nature of an existing malfunction.

Depending on the complexity of split systems, as well as the number of functions under control, the decoding of these aggregates can take from one and more page of the printed text.

Any error of the ELECTROLUX air conditioner is issued by the control unit code and reports the faulty functioning of the sensors, the winding of the compressor, overloads at the temperature and so on.

Each series of air conditioners from Electrolux can have its own “firmware” of codes.

Lesser air conditioners are equipped with automatic troubleshooting feature. Having found a problem, the system issues an air conditioner error code Lesser on the front panel of the indoor unit. Error code is a special combination of flashing LEDs. Error air conditioner lesser is highlighted until measures have been taken to eliminate it.
