Split system error fantasy timer pre def. Error codes, malfunctions and repair of Carrier air conditioners. What to do if the air conditioner does not follow the remote control commands

The indoor unit of the air conditioner can diagnose problems and at the same time fix them (if possible). A list of faults and their codes are contained in the table (see below).
In the process of diagnosing a malfunction, the green indicator (P) and the orange indicator (R) flash with a frequency of 0.1 sec, indicating a malfunction code. An orange indicator (R) corresponds to tens in the number - a fault code. The green indicator (P) corresponds to the units in the number - the fault code.
2 seconds elapse between flashing orange and green indicators. The sequence is repeated at intervals of 4 seconds.

Example: fault code 13:

  • Orange light flashes once
  • Both indicators are off 2 seconds
  • The green indicator blinks three times at 0.5 second intervals.
  • Both indicators are off 4 seconds

The sequence is repeated until the malfunction is corrected. If the DTC is less than 10, then the orange indicator does not flash.

SYMPTOMS NOT AIR CONDITIONING DEFECTS
Symptom 1: the air conditioner does not work
■ The air conditioner does not start immediately after pressing the ON / OFF button on the remote control. If the activity indicator is on, the system is in a normal state. To prevent overload of the compressor motor, the air conditioner starts 3 minutes after pressing the button.

■ If the operation and defrost indicators "PRE-DEF *" are on, it means that the heating mode is selected. When the air conditioner is turned on, the compressor does not start immediately (if the cold air protection function is activated) because the temperature of the air leaving the indoor unit is too low.

Symptom 2: Switching to Fan Only mode during cooling operation
■ To prevent freezing of the indoor unit evaporator, the system automatically switches to "Fan only" mode and returns to cooling mode after a while.

■ When the room temperature drops to the set value, the compressor stops and the indoor unit automatically switches to "Fan only" mode, and when the temperature rises, the compressor starts again. The same principle of operation is incorporated into the control system when operating in heating mode.

Symptom 3: white fog comes out of the block
Symptom 3.1: indoor unit
■ When the relative humidity of the air is high and the inner surface of the cooling unit is heavily soiled, the temperature distribution in the room becomes uneven. It is necessary to completely clean the indoor unit. For detailed cleaning information, contact your local dealer. This work must be done by a qualified technician.

Symptom 3.2: indoor and outdoor units
■ When the system switches to heating mode after the defrost operation is completed, the moisture generated during defrosting turns into steam and is discharged from the system.

Symptom 4: noise from the air conditioner in cooling mode
Symptom 4.1: indoor unit
■ When the system is operating in cooling mode or stopped, a continuous low hissing sound is heard.
A sound is heard when the drain pump (optional accessory) is running.

■ When stopping the system in heating mode, a quiet crackling sound is heard.
Sounds are caused by the deformation of plastic parts when their temperature changes.

Symptom 4.2: indoor and outdoor units
■ During system operation, a continuous, low hissing sound is heard. The sound is caused by refrigerant vapor passing through the indoor and outdoor units.

■ At startup, immediately after the end of a stop operation, or during defrosting operation, a faint hissing sound is heard. The sound is generated when the speed of circulation of the refrigerant in the refrigerant circuit changes.

Symptom 4.3: outdoor unit
■ The pitch of the air conditioner operating changes. A change in pitch is caused by a change in rotation speed
fan.

Symptom 5: dust is blown out of the unit
■ When using the air conditioner for the first time after a long period of inactivity.
Dust accumulated in it during the period of inactivity is blown out of the unit.

Symptom 6: the unit emits foreign odors
■ The unit can absorb odors from the room, furniture, tobacco smoke, etc., and then release them into the air stream.

Symptom 7: low speed of the outdoor unit fan
■ During air conditioner operation, the fan speed is adjusted to optimize system performance.

TROUBLESHOOTING
Air conditioner malfunctions and their causes
If any of the following abnormalities occurs, stop the air conditioner, turn off the power, and contact your local service organization.

■ The unit operation indicator blinks quickly (5 blinks per second). The operation indicator continues to flash rapidly after turning the power off and on again (see tables 7-1a, 7-1 b and 7-2).
■ The remote control has malfunctioned or the buttons on the remote control do not work.
■ A safety device (fuse or circuit breaker) often trips.
■ Foreign objects or water have fallen into the unit.
■ Water flows out of the indoor unit.
■ Other malfunctions have occurred.
If any malfunctions of the air conditioner, except for the above cases or malfunctions, the causes of which are obvious, analyze the behavior of the air conditioner according to the recommendations below (see the table).

Air conditioners have become indispensable household appliances designed to maintain human comfort. But because of the many different buttons, sometimes, especially for beginners, it is difficult to choose and find a suitable air conditioner mode.

Using this device is not as difficult as it might seem at the very beginning. As a rule, the buttons and their designations are the same on all remotes, and if you learn and remember them, you can easily use different models in the future.

The remote control is a monoblock with control buttons and a display that shows the selected mode. At the very end there is a special LED with infrared rays. Thanks to this diode, when the device is directed to the air conditioning device, it is possible to remotely control household appliances. When you constantly press the button with your finger, the signal is sent to the air conditioner all the time, and the battery charge is spent. But in a quiet state of the remote control, the battery is not active, which helps to economically consume electrical energy.

Remote control with a classic set of buttons

Designations on the remote control of air conditioners

Consider the basic designations on the control device:

  1. The dry function located in the air conditioner dehumidifies the air in the apartment. This button is very helpful during rainy periods, in autumn or spring before turning on the heating, when the room is humid.
  2. The trv button means the thermostatic valve is working. In other words, this function can be used to adjust the cooling operation.
  3. The fan icon indicates fan speed control or air flow rate mode. By pressing this button again, you can change the operating speed to the required one.
  4. The heat function on any air conditioner literally translates as heating. It is possible to turn on the heating of the room thanks to the warm air currents. The heat mode is indicated by the schematic drawing of the sun on the air conditioner.
  5. The dehumidification mode is the same dry mode in the air conditioner, only it is called differently and has a designation in the form of a drop.
  6. The cool button performs the reverse function of heating. Thanks to this button, you can turn on the room cooling mode. This is especially good on hot summer days, when the heat makes the stay in a city apartment unbearable. This button is indicated by a snowflake.
  7. The TURBO function means enhanced airflow. By turning it on, you can force the fan to deliver an increased air flow at a high speed. Thus, artificial ventilation of the room is carried out without opening the windows. And the time will be spent several times less.

TURBO button

  1. The Swing function helps the air to be evenly distributed throughout the apartment. This is due to a special flap movement.
  2. The Ifeel mode is designed to determine the individual comfort temperature. Due to the fact that users often do not know what temperature in the room will be most comfortable for them, a thoughtless waste of electricity occurs. And in this case, the I feel button comes to the rescue. The technology is distinguished by high accuracy: if for some reason the temperature in the apartment is below the required degree, the household appliance, set to this mode, begins to warm the air, turning on the heat mode automatically. Conversely, when the temperature rises, the device immediately turns on the air cooling. Thanks to this function, the room temperature will be kept as comfortable as possible for your stay.
  3. Hi or H1 - the designation of these characters appears on the screen during failures as an error. When these combinations appear on the display, you should know that the device, for some reason, has entered the defrosting mode. In order to eliminate the error, you just need to turn off the remote control, wait a while and turn it back on. After that, you can set the required mode.
  4. Pre def is also an error code that often occurs in the operation of air conditioners. It means that contact with the temperature sensor is temporarily lost. This happens due to a variety of failures in the electronic system or in case of problems with electricity. In order to restore the operation of the device, you just need to wait for the contact with the temperature sensor to resume.
  5. On timer / Off timer - the setting will help to set the operation of the device to automatic mode. It can be configured to disable or enable the desired mode at a specific specified time. This function is very convenient at night or during the absence of the apartment owners.

On / Off timer button

  1. The on and off buttons of the household appliance are necessary in order to turn on or off the equipment if necessary.
  2. The CANCEL or CANCEL button helps the user to cancel an erroneous mode.
  3. Using the CLOCK button, you can set the time, which is very convenient for automatic mode, on / off timer and simply using this device as a clock.
  4. The LOCK function helps to lock all buttons on the remote. This feature helps out when there are children or pets in the family, and they accidentally press and thereby knock all the settings.
  5. If the remote has a backlight function, the LED button may come in handy. It is needed to automatically illuminate the remote control. Helps out well in the dark.

What to do if the air conditioner does not follow the remote control commands

If the device does not respond to the remote control, you should:

  • make sure that the power supply system is working;
  • check the integrity of the case, screen, buttons;
  • make sure that the remote control emits infrared rays by taking a photo, otherwise you will need to purchase a new remote control;
  • check the electrical network in the room to eliminate the cause of the power surges;
  • check the batteries for performance.

In order for the remote control not to be lost and not subjected to mechanical stress, blows, presses, it is necessary to purchase a special mount for it. You need to install it in a place accessible for use, handy and convenient.

The remote control for the air conditioner is an important component of this household electrical appliance. Without it, the air conditioner can only be started in automatic mode. But if for some reason the remote control is lost or broken and cannot be restored, you can purchase a universal one, suitable for all models and manufacturers.

Universal remote control for air conditioners

An inverter air conditioner is a device whose operation is independently controlled by a compressor. When the maximum temperature is reached, such an air conditioner does not turn off, but reduces degrees to maintain a comfortable temperature at a constant level.

If you take a little time and understand the designations of the buttons on the air conditioner remote control, it turns out that using this device is not so difficult. Moreover, only a few main buttons stand out, the rest are used quite rarely.

Why is the air conditioner blinking (flashing)?

The blinking of the air conditioner indicates errors in its operation. It warns the user about the presence of malfunctions, ignoring which can lead to extremely undesirable consequences - failure of the engine, compressor or board. Blinking indicators are equipped with those models of home air conditioners that are equipped with a self-diagnosis system. It prevents the device from turning on and provokes the flashing of the timer.

A blinking air conditioner can signal the following malfunctions:

  • Data transfer between the indoor and outdoor unit is disrupted;
  • Overvoltage or undervoltage in the network;
  • Refrigerant pressure exceeded;
  • Compressor temperature is out of range;
  • Broken evaporator thermal sensor;
  • There is no condensate drainage, etc.
