Split AC Problems and Solutions

● Cautions

Regular maintenance includes cleaning air filters, the unit cabinet, and the condenser coil and conducting a general inspection. But you have to be aware of some cautions:

1) Always disconnect the power supply before removing access panels to service the unit. Failure to do so can result in severe injury or death.

2) Turn off the main power before performing any maintenance.

● Cleaning Air Filters

Split ACs feature washable filters. It is crucial to keep air filters clean.

1) Inspect them monthly during constant operation and weekly in new buildings for the first four weeks.

2) Clean the filters with mild detergent and water and ensure they are thoroughly dried before reinstallation.

● Cleaning Condenser Coils

Unfiltered air can clog the condenser coil with dust and dirt in any type of AC. To maintain efficient operation, brush the coil's surface vertically with a soft-bristled brush. Keep vegetation away from the condenser coil area.

● When the Air Conditioner Is Not in Use for an Extended Period

1) Operate the air conditioner on air circulation mode for 2-3 hours to dry internal parts.

2) Turn off the circuit breaker to prevent fire.

● When Using the Air Conditioner Again

1) Clean and reinstall the air filter.

2) Ensure the air inlet and outlet are not blocked.

3) Run the air conditioner on air circulation mode for 2-3 hours to dry internal parts.

● Efficient Operation

To keep your Air conditioner operating perfectly for a long time, follow the steps below:

1) Avoid overcooling the room to save electricity and maintain health.

2) Keep blinds or curtains closed to prevent direct sunlight from entering.

3) Clean the air filter regularly to ensure optimal airflow and cooling efficiency.

4 Ensure doors and windows are tightly shut to keep cool air inside.

5) Occasionally ventilate the room by opening windows instead of air conditioning.

● AC Troubleshooting

Here is a guide on how you can solve some common dual-fan AC issues without calling a professional service:

i) Check timer settings.

ii) Ensure the fuse has not blown or the circuit breaker has not tripped.

iii) Verify the remote controller does not display an error signal; if it does, contact a service center.

Determine if the odor is coming from damp walls, carpet, furniture, or cloth items.

This can occur when the AC airflow cools the warm air.

After restarting, the AC may not operate for about three minutes due to a protection device. Wait for the operation to begin.

i) Check if the air filter is dirty.

ii) Allow time for the room to cool down if it was initially very hot.

iii) Ensure the temperature is set correctly.

iv) Ensure air inlet or outlet vents are not obstructed.

Check if the circuit breaker has tripped.

The AC will automatically retrieve previous operating conditions after a power outage, but additional functions need to be reset manually.

● Professional Inspection

To ensure safety and efficiency, have a qualified serviceman do the AC maintenance by checking the entire system annually or more frequently if necessary. The inspection should cover:

-        Cleaning filters

-        Checking motors and drive system components

-        Cleaning condenser coils

-        Mechanical cleaning of safety controls

-        Inspecting electrical components and wiring

-        Cleaning the condensate drain

-        Ensuring duct connections are sound and sealed

-        Verifying the unit mounting support is secure

-        Checking for any obvious deterioration
