Sharp Air Conditioner Troubleshooting
| Symptom | Troubleshooting |
|---|---|
| Air conditioner does not run if attem pt to immediately restart after a stop. | To protect the air conditioner upon immediate restart after a stop, the microcomputer controller will delay the unit for 3 minutes before the air conditioner will run. |
| Air conditioner blows out bad smell when it is initially started. | The air conditioner itself has no bad smell. If a bad smell has been accumulated from the environment, clean the airfilter. |
| You may hear ”Water Flowing” noise | When the air conditioner is started, or the compressor is started or stopped during running or the air conditioner is stopped, sometimes you may hear fluid gurgling noises. This is not a fault – it is the sound offlowing refrigerant. |
| Sometimes a thin mist will flow out of the outlet when air conditioner is running under cooling mode. | This might occur when indoor temperature and humidity are high. This is because the indoor air is quickly cooled down. After a period of time, the mist will disappear with the decrease of indoor temperature and humidity. |
| You may hear a slight cracking sound when the air conditioner is started or stopped. | This is the sound of friction caused by expansion and/or contraction of panel or other parts due to the change of temperature. |
| The unit will not run | Has the power been shut down? Has the circuit breaker device tripped off? Is the Timer correctly used? Have the wiring or connections been a damaged?P |
| Cooling (Heating) efficiency is not good. | Is Temp. setting suitable? Are inlet and outlet vents obstructed? Are the windows and doors closed? Is the fa n speed_set at low speed? Is there too much dust accumulated and obstructing the filter? |
| Wireless remote control is not working | Check that there is no magnetic or electrical interference near the main unit that may be affecting the operation of the controller. |
| Water is dripping or leaking from the indoor unit | The air humidity is on the high side. Condensing water has overflowed. The connection of indoor unit drainage pipe has been loosened. |
| Noise from indoor unit | Fan or compressor relay is switching on or off. When defrosting is started or stopped, there is a sound of refrigerant flowing in the reverse direction. |
| Moisture on air outlet vent | If unit is running under high humidity for a long time, moisture will be condensed on the air outlet grill and may drip off. |
