Ceiling air conditioner blinking lights - Causes and Solutions
1. Steps to diagnose errors on ceiling air conditioners
1.1. For Wall-Mounted Remote-Controlled Models
This model will self-diagnose errors and display corresponding error codes on the remote control. So, you just need to look at the corner of the control screen (near the eye symbol) to know what problem the unit is encountering.

- Step 2: Aim the control signal light towards the ceiling-mounted air conditioner and continuously press the “CANCEL” button. Each time you press the button, the 'Power' light on the air conditioner will blink once, and the error code will sequentially appear on the corresponding screen each time the 'Power' light blinks.
- Step 3: The 'Power' light will illuminate and emit a continuous beeping sound for about 4 seconds once you have correctly identified the error code the ceiling-mounted air conditioner is encountering,
- Step 4: After knowing the error code, simply press and hold the “CANCEL” button for 5 seconds to end the error checking process on the ceiling-mounted air conditioner. Additionally, this feature will automatically turn off if you do not perform any further actions within about 20 seconds,
- Step 5: To temporarily clear the error code, you can turn off the air conditioner or press the “AC Reset” button on the remote. Then, simply restart the air conditioner.
1.3. For New Generation Handheld Remote-Controlled Air Conditioners
The process of diagnosing errors for the new generation air conditioner models is similar to older models but with fewer steps, specifically:
- Step 1: Press and hold the “CANCEL” button on the remote for about 5 seconds until the display shows “00”.
- Step 2: Press the “CANCEL” button in rhythmic pulses (meaning, don’t hold it down) to check each error code; the ceiling air conditioner will emit a beep if it’s the correct error code.
- Step 3: At this point, the error code appearing on the control panel is the same as the one the ceiling air conditioner is encountering.
2. Signs of Identifying Ceiling Air Conditioner Blinking Light Errors
When the ceiling air conditioner encounters blinking light errors, it exhibits the following signs:
- Approximately every 30 minutes, the unit blinks its lights once, and you don’t feel any cool air emanating from it.
- The ceiling air conditioner autonomously turns on/off irregularly.
- The light on the ceiling air conditioner remains on, doesn’t turn off, and the air vents close.
When noticing these signs, it means the ceiling air conditioner is experiencing an issue, and you should inspect the unit to identify the cause and promptly rectify the error.
