TCL AC Failure Display Screen
Basic Troubleshooting:
- If an error code appears on the TCL AC display, turn the unit off and then back on to attempt a reset.
Error Code Display:
- The protection display function can be selected in the hardware settings.
- When the protection display is active, the controller will exhibit the error code.
- The digital LED provides both the error code and the temperature.
- In cases of multiple failures, the primary error will be displayed first.
- Failures specific to the outdoor unit will persist for a maximum of 2 minutes after recovery.
Outdoor Failure or Error Light Indicators:
- The outdoor power board has an LED indicator.
- When the compressor is running: LED is continuously illuminated.
- Lack of feedback from the compressor: LED blinks (on for 1 second, off for 1 second).
- In case of a failure: LED lights up for 0.5 seconds, goes off for 0.5 seconds, and this pattern repeats several times before going off for 3 seconds to indicate an error cycle.

TCL Split System AC Error Codes FAQ
What should I do if an error code appears on my TCL AC display?
If an error code appears on the TCL AC display, turn the unit off and back on again to attempt a reset. You can also try cleaning the indoor AC unit to clear the error code. If water is leaking from the indoor AC unit, you can try the troubleshooting methods provided.
How does the outdoor failure or error light display work?
There is an LED on the outdoor power board. When the compressor is running, it is normally illuminated. When there is no feedback of the signal to the power board from the compressor, the light will blink by lighting 1 second and going out 1 second. If a failure occurs, it will light 0.5 seconds then go out 0.5 seconds, blinking several times and go out 3 seconds for a cycle to indicate a failure.
What should I do if my TCL AC shows a P9 error?
The P9 error indicates a Drive protection (software control issue). This means a computer-controlled or software component of the AC is not working properly. This type of issue may require an AC professional to address.
How can I reset my TCL AC split system with error codes?
To reset your TCL AC split system, turn the unit off and then back on. If the error persists, you may need to clean the indoor AC unit or refer to the specific error code for further troubleshooting.
What does it mean if water is leaking from my indoor AC unit?
If water is leaking from the indoor AC unit, it could be due to a clogged drain line, a frozen evaporator coil, or other issues. It’s recommended to check the drain line for clogs and ensure that the unit is not set to a temperature that’s too low, causing the coil to freeze. If the problem persists, consult with a professional.
How can I download the TCL Wall Mounted Split Air Conditioner Service Manual?
The TCL Wall Mounted Split Air Conditioner Service Manual is available for specific TCL AC Models like KFTHP-12, KFTHP-18 & KFTHP-24. You can usually find it on the official TCL website or contact their customer service for assistance.
What should I do if there’s an LED blinking on the outdoor power board?
If there’s an LED blinking on the outdoor power board, it indicates a potential issue. The LED behavior, such as the duration it stays on and off, can provide clues about the specific problem. For instance, if the LED lights for 0.5 seconds and then goes out for 0.5 seconds repeatedly, it indicates a failure. It’s recommended to refer to the user manual or contact a professional for a precise diagnosis.

Lowell,
Can you tell us what part of the TCL split system AC is flashing the codes? Inside unit or outside?

i have TAW05crb0N model and when i turn it of it will immediately turn off flash a sequence of lights then show the number 23 and code f2 so what do i do
Tam,
When you switch on the first TCL TAC-12CSA/XAB11 unit and see the display showing 4A and 0A without cool air coming out, this could potentially indicate an issue with the compressor or cooling coils, as these are core components of the AC system.
A malfunctioning compressor, dirty cooling coils or low refrigerant levels might lead to the AC not blowing cold air.
As for the second AC unit showing 2A, this could be a sign of an electrical issue, such as a blown fuse or tripped breaker.
It’s important to inspect the electrical connections and ensure the thermostat is set to an adequate temperature, as these could also cause the AC not to blow cold air.

Hello,
I have 2 units of TCL TAC-12CSA/XAB11. When I switch on the first one it Shows 4A and 0A with no cool air coming out. When I switch on the second AC it shows 2A but works however not optimally. Kindly advice what these codes represent as I do not have the manuals. They have only been operational for 3 weeks.
Jannie,
Can you give us the model number of your TCL split system AC?
