Возврат к списку

Продукция японской корпорации Fujitsu известна во всем мире своей инновационностью, технологичностью и надежностью. Система интеллектуальной диагностики позволяет с высокой точностью определить ошибки и неисправности в работе кондиционера.

Индикация неисправностей отображается как с помощью кодов на пульте управления климатической системой, так и в виде мигания светодиодных индикаторов на внутреннем блоке кондиционера.

Обслуживание кондиционеров Fujitsu предполагает привлечение высококвалифицированных специалистов, поэтому в случае возникновения проблем в работе Вашей техники, позвоните в сервисный центр “Сервис-Климата”, назовите код ошибки оборудования и ожидайте приезда специалистов.

This is our latest fujitsu AC troubleshooting guide. We included the full list of fujitsu aircon error codes and some troubleshooting procedure.

Troubleshooting at the remote control LCD

If an error occurs, the following display will be shown. (“EE” will appear in the set room temperature display.)

If “CO” appears in the unit number display, there is a remote control error.

Refer to the installation instruction sheet included with the remote control. If you need still need a helping hand, our previous how to repair ac remote control guide may help.

Troubleshooting at the outdoor unit LED

Make a TEST RUN in accordance with the installation instruction sheet for the indoor unit.

When a malfunction occurs in the outdoor unit, the LED on the circuit board lights to indicate the error.

Refer to the following table for the description of each error according to the LED

LED	Error
1 flash	Communication error (Indoor unit – Outdoor unit)
2 flash	Discharge pipe temperature sensor
3 flash	Outdoor heat exchanger temperature (outlet) sensor
4 flash	Outdoor temperature sensor
5 flash	Outdoor heat exchanger temperature (mid) sensor
6 flash	Discharge pipe temperature abnormal
7 flash	Compressor temperature sensor
8 flash	Heat sink temperature sensor
9 flash	Pressure switch abnormal

General Troubleshooting

1. Fujitsu AC doesn’t operate immediately

Possible causes:

• If the unit is stopped and then immediately started again, the compressor will not operate for about 3 minutes, in order to prevent fuse blowouts.
• Whenever the Power Supply Plug is disconnected and then reconnected to a power outlet, the protection circuit will operate for about 3 minutes, preventing unit operation during that period.

2. Fujitsu AC have noise

Possible causes:

• During operation and immediately after stopping the unit, the sound of water flowing in the air conditioner’s piping may be heard. Also, noise may be particularly noticeable for about 2 to 3 minutes after starting operation (sound of coolant flowing).
• During operation, a slight squeaking sound may be heard. This is the result of minute expansion and contraction of the front cover due to temperature changes.
• During Heating operation, a sizzling sound may be heard occasional. This sound is produced by the Automatic Defrosting operation

3. Fujitsu AC have smell

Possible cause:

• Some smell may be emitted from the indoor unit. This smell is the result of room smells (furniture, tobacco, etc.) which have been taken into the air conditioner.

4. Mist or steam are emitted in Fujitsu AC

Possible causes:

• During Cooling or Dry operation, a thin mist may be seen emitted from the indoor unit. This results from the sudden Cooling of room air by the air emitted from the air conditioner, resulting in condensation and misting.
• During Heating operation, the outdoor unit’s fan may stop, and steam may be seen rising from the unit. This is due to Automatic Defrosting operation.

5. Fujitsu AC airflow is weak or stops

Possible causes:

• When Heating operation is started, fan speed is temporarily very low, to allow internal parts to warm up.
• During Heating operation, if the room temperature rises above the thermostat setting, the outdoor unit will stop, and the indoor unit will operate at very low fan speed. If you wish to warm the room further, set the thermostat for a higher setting.
• During Heating operation, the unit will temporarily stop operation (between 7 and 15 minutes) as the Automatic Defrosting mode operates. During Automatic Defrosting operation, the OPERATION Indicator Lamp will flash.
• The fan may operate at very low speed during Dry operation or when the unit is monitoring the room’s temperature.
• During SUPER QUIET operation, the fan will operate at very low speed.
• In the monitor AUTO operation, the fan will operate at very low speed.

6. Water is produced from Fujitsu AC outdoor unit

Possible cause:

• During Heating operation, water may be produced from the outdoor unit due to Automatic Defrosting operation.

7. Fujitsu AC doesn’t operate at all

Possible causes:

• Is the Power Supply Plug disconnected its outlet?
• Has there been a power failure?
• Has a fuse blown out, or a circuit breaker been tripped?
• Is the timer operating?

7. Fujitsu AC not cool

Possible causes:

• Is the Air Filter dirty?
• Air the air conditioner’s intake grille or outlet port blocked?
• Did you adjust the room temperature settings (thermostat) correctly?
• Is there a window or door open?
• In the case of Cooling operation, is a window allowing bright sunlight to enter? (Close the curtains.)
• In the case of Cooling operation, are there heating apparatus and computers inside the room, or are there too many people in the room?

7. Fujitsu AC operates differently from the Remote Controller’s setting

Possible causes:

• Are the Remote Controller’s batteries dead?
• Are the Remote Controller’s batteries loaded properly?

How to clean Fujitsu air conditioner intake grille?

1. Remove the Intake Grille

• Place your fingers at both lower ends of the grille panel, and lift forward; if the grille seems to catch partway through its movement, continue lifting upward to remove.
• Pull past the intermediate catch and open the Intake Grille wide so that it become horizontal.

2. Clean with water

Remove dust with a vacuum cleaner; wipe the unit with warm water, then dry with a clean, soft cloth.

3. Replace the Intake Grille

• Pull the knobs all the way.
• Hold the grille horizontal and set the left and right mounting shafts into the bearings at the top of the panel.
• Press the place where the arrow on the diagram indicates and close the Intake Grille.

• Dust can be cleaned from the air filter either with a vacuum cleaner, or by washing the filter in a solution of mild detergent and warm water. If you wash the filter, be sure to allow it to dry thoroughly in a shady place before reinstalling.
• If dirt is allowed to accumulate on the air filter, air flow will be reduced, lowering operating efficiency and increasing noise.
• During periods of normal use, the Air Filters should be cleaned every two weeks.

How to replace Fujitsu air conditioner air filter?

Replace filters with the following components (purchased separately).

• POLYPHENOL CATECHIN AIR CLEANING FILTER : UTR-FA13-1
• Negative air ions deodorizing filter: UTR-FA13-2

1. Open the Intake Grille and remove the Air filters.

2. Replace them by two new Air cleaning filters.

• Remove the old air cleaning filters in reverse order of their installation.
• Install in the same way as for installation of the air cleaning filter set.

3. Install the two Air filters and close the Intake Grille

In regard to the Fujitsu air conditioner air filter:

POLYPHENOL CATECHIN AIR CLEANING FILTER (one sheet)

• The Air Cleaning Filters are disposable filters. (They can not be washed and reused.)
• For storage of the Air Cleaning Filters, use the filters as soon as possible after the package has been opened. (The air cleaning effect decreases when the filters are left in the opened package)
• Generally, the filters should be exchanged about every three months.

Negative air ions deodorizing filter (one sheet) – light blue

• The filters should be exchanged about every three years so as to maintain the deodorizing effect.
• Filter frame is not a one-off product.

Maintenance of Deodorizing Filters

In order to maintain the deodorizing effect, please clean the filter in the follow way once three months.

1. Remove the deodorizing filter.
2. Clean with water and dry in the air.
3. Reinstall the deodorizing filter.
