Aircon Louvre Swing Motor
The louvre swing motor moves the indoor flap up and down to direct airflow. When it fails, the flap may stop moving, jitter, or stay stuck in one position.
What This Part Does
The louvre swing motor moves the indoor air flap. It changes airflow direction during swing mode.
The motor follows commands from the control path. It works with the vane linkage to move the flap smoothly.
If the motor stops or slips, the flap may not move as expected.
How You Would Notice
The flap may stay in one position and ignore swing commands. Some units jitter or move a little, then stop.
You may hear a small clicking sound from the flap area when the unit tries to move it.
Airflow direction can feel wrong even though cooling is still present.
- Swing flap not moving
- Flap jitters or clicks during swing command
- Airflow direction stuck in one angle
It Might Not Be The Louvre Swing Motor
A jammed vane linkage can block flap movement even when the swing motor is fine.
Remote or receiver issues can also stop the swing command from reaching the unit.
Indoor PCB faults can stop control signals to the motor. We check command, motor, and linkage path together.
How We Check
We confirm the unit is receiving the swing command first. Then we observe flap response and sound pattern.
We inspect the linkage for jams or broken movement points before blaming the motor.
If the linkage is free, we check the swing motor response and control behavior.
Replacement is recommended only when motor behavior is the confirmed cause.
What We Find And What Happens Next
Swing-flap issues usually end in motor fault, linkage jam, command-path issue, or normal motor with a setup problem.
| Finding | Next Step |
|---|---|
| Swing motor not responding | Replace swing motor and retest flap movement |
| Linkage jam or break | Repair linkage and retest |
| Command path issue | Check receiver or indoor PCB path |
| No part fault found | Confirm settings and usage pattern |
About The Repair
Swing-motor replacement is usually a small indoor-unit repair. Access is needed around the flap assembly.
The repair only helps if the command path and linkage are healthy. A stuck linkage can make a new motor fail again.
We confirm the movement path before recommending replacement.
After Replacement
The flap should move smoothly when swing mode is used. Clicking and jitter from motor failure should stop.
If the flap still does not move, the linkage or control path needs another check.
We retest flap movement and command response before closing the job.
When We Tell You To Wait
If cooling is normal and only swing mode is affected, planned repair may be reasonable in some cases.
If the flap is jammed and causing noise every cycle, earlier repair is better to avoid more wear.
We will tell you when the issue is minor convenience loss versus active mechanical stress.
