Troubleshooting Guide

Problem: The motor is heard operating but the air-conditioner dose not work when the indoor unit is powered on

Cause: Since the air-conditioner is powered on, it will come to working condition as long as you press the ON/OFF button of the remote control and the signal is well received.

Problem: The compressor stops running but the indoor fan motor keeps working when it is at cooling mode with the indoor temperature higher than set temperature.

Cause: If you turn off the air-conditioner and restart it immediately, it will return to normal in 3 minutes, after that, the air-conditioner will automatically adjust the indoor fan speed to what you set.

Problem: The compressor works discontinuously at dehumidifying mode.

Cause: The air-conditioner will automatically control the working of the compressor according to the inside temperature

Problem: The air-conditioner dose not work while the LED display is on.

Cause: The TIMER is set with the air-conditioner,it will be in hold on condition. If the TIMER setting is cancelled, the air-conditioner will return to normal working condition.

Problem: The compressor works discontinuously at cooling and dehumidifying mode, and the indoor fan motor slows down.

Cause: The compressor stops internally or the fan motor slows down to prevent the indoor heat exchanger from being frozen.

Amana Through the Wall (TTW) AC Error Codes and Troubleshooting

/0 Comments/in , /by

Amana Ac Maintenance Dubai

Amana Air Conditioner Normal Operating Sounds And Conditions:

Popping Or Gurgling Sounds: This sound is the refrigerant traveling through the lines. This is a normal sound which may be heard for a few seconds after the unit shuts off.

Water Trickling Sounds: This sound is produced by the water as it is picked up and run over the coils. This procedure improves the efficiency of the unit and helps with water removal.

Water Dripping: Water will collect in the base pan during high humidity days.

Starting Delay: You may notice a short delay in the startup if you try to restart the unit too soon after turning it off or if you adjust the thermostat right after the compressor has shut off. This delay protects the compressor.

Error Code: F1

Status: Outdoor ambient thermostat not registering on the board.

Corrective Action: Replace or re-connect the thermostat.

Error Code: F2

Status: Outdoor ambient thermostat not registering on the board.

Corrective Action: Replace or re-connect the thermostat.

Error Code: F4

Status: Outdoor coil thermostat not rgistering on the board.

Corrective Action: Replace or re-connect the thermostat.

Error Code: FJ

Status: Indoor discharge thermostat not registering on the board.

Corrective Action: Replace or re-connect the thermostat.

Additional Information

  • The remote control will operate all the control panel features. Instructions will be the same.
  • The “COOL” circuit has an automatic 3 minute time delayed start if the unit is turned off and on quickly. This prevents overheating of the compressor and possible circuit breaker tripping. NOTE: The fan will continue to run during this time.
  • The control will maintain any set temperature between 60°F and 90°F (cooling), 55°F and 80°F (heating).
  • The control is capable of displaying temperature in degrees (Fahrenheit) or degrees (Celsius). To convert from one to the other, press and hold the UP and DOWN Temperature Selection Pads at the same time for 3 seconds.

Compressor

The compressor is hermetically sealed, permanently lubricated and requires no additional oiling.

Front Panel And Grille

The front panel and grille can be cleaned with a mild soap or detergent. Do not use hydrocarbon-based cleaners (e.g. acetone, benzene, naphtha, gasoline, etc.) to clean the front panel or grille. Use care when cleaning the control area. Do not use an excessively wet cleaning cloth.

Scheduled Ac Maintenance

To achieve continuing top performance and high efficiency, a regular cleaning/inspection schedule must be established. Maintaining this schedule can be accomplished by either a local maintenance staff or an authorized service and must follow the instructions described in this manual.

  • If the unit is operated in a dusty climate, dust may collect in the base pan and clog the condenser coil. It is advisable to remove the unit from the sleeve and thoroughly clean the base pan and condenser coil on a periodic basis.
  • If the unit is installed ocean side or in a corrosive atmosphere, its life may be greatly reduced by the corrosive environment. Under these conditions, the unit should be removed from the sleeve and completely cleaned once a year. At that time any scratches or blisters on the painted surfaces should be sanded and repainted.

Air Conditioner Outdoor Coil Cleaning

The coils on the outdoor side of the air conditioner should be checked regularly. For cleaning outside coil, remove the 6 screws that mount the condenser coil top cover to condenser shroud.

  3. Dirty air filter — clean the filter.
  4. Fan speed is set to LOW — increase.
  5. Other sources of heat in the room — check

Problem: Indoor unit does not work straight after restarting it

Possible cause and solution: This is not a fault. Once the air conditioner is stopped, you will have to wait for approximately 3 minutes before the unit can be restarted

Problem: Strange odour coming from the outlet

Possible cause and solution:

  1. Odour in the room (from building material, furniture or smoke) is recirculated
  2. Dirty air filter — clean the filter

Problem: Noise like running water when cooling

Possible cause and solution: Refrigerant is flowing inside the unit — no cause for concern

Problem: Mist is emitted when cooling

Possible cause and solution: Cold air used for rapid cooling of the air in the room may resemble fog — no cause for concern

Problem: Mist is emitted when heating

Possible cause and solution: Moisture from the defrosting process generates mist — no cause for concern.

Problem: Low noise is emitted during operation.

Possible cause and solution:

  1. A low hissing sound is caused by the refrigerant flowing.

Safety Cautions

  1. Do not use unit near gas appliance, fires or in the vicinity of flammable liquids.
  2. Do not let children put their fingers into the air outlet to avoid danger.
  3. Do not incline the unit more than 35° while moving the unit.
  4. Do not beat or extrude unit to prevent unit broken, do not vibrate the unit.
  5. Keep the unit two meters away from TV sets or radios to avoid the risk of electromagnetic interface.
  6. Do not use unit with the air outlet too close to walls or cover the outlet to avoid overheating.
  7. Do not use the unit in a very crowded room.
  8. Do not use the unit directly under sunshine to avoid surface color fading.
  9. Do not use the unit in water or near water to avoid leakage of electricity.
  10. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or similar qualified person in order to avoid a hazard.
  11. when the room temperature is higher than 25 degrees, it is better not to use the heating function.

Special Guide Line

  1. Do not incline the unit more than 5° degree, if so, please turn off power supply immediately and ask for advice from your local dealer.
  2. Do not spray insecticide or other chemicals to avoid deformation of plastic case.
  3. The unit, due to its moving feature, it can be moved from room to room and it is different from window type or split type air conditioner. If the unit cannot cool down the room temperature efficiently, it is not the unit’s quality problem. The unit can only work efficiently in certain room area. ( see technical specification )
  4. In order to prolong the unit’s lifetime, please empty the water completely in the water tray at the bottom of the unit while the unit is not going to use for a long period of time.
  5. The unit can drain water automatically. It is not necessary to use the hose to drain the water under the cooling mode because the condenser can evaporate the water.
  6. when turning “on” or “off” the unit under the heating mode, some noise of airflow inside the unit can be heard obviously, this is not a faulty problem, no need to repair.
