- Monitor the system to see if the error flashing light code has cleared.
-
Observation and Verification:
-
- Check if the system is set to the appropriate mode (heat or cooling).
- Ensure that the heating or cooling is functioning properly after the reset.
Additional Tips:
-
Previous Cleanliness: Reflect on the state of the unit before it was cleaned. If it was notably dirty inside and outside, that could have contributed to the current issue.

Recurring Alarm: If the error persists after following the reset and cleaning steps, it might indicate a refrigeration leak caused by prolonged clogging. In such cases, it’s advisable to contact a professional HVAC technician to assess the system’s pressures and further diagnose the problem.
Common Causes of Fujitsu Timer Light Flashing 10 Times
When the timer light on your Fujitsu air conditioning unit blinks 10 times, it’s essential to understand the potential causes behind this issue. By identifying the root cause, you can take appropriate actions to resolve the problem and restore your AC system to optimal functioning. Let’s explore some common causes:
Faulty Connection Between Indoor and Outdoor Units
A faulty connection between the indoor and outdoor units of your Fujitsu AC system can trigger the timer light to blink 10 times. This connection issue could arise due to loose or damaged cables, improper installation, or even a malfunctioning circuit board. To fix this, you’ll need to inspect the connection points and ensure everything is securely connected and intact. If you notice any damage, it’s best to seek professional assistance for repairs.
Faulty PCB (Printed Circuit Board)
The PCB, or printed circuit board, is responsible for controlling various functions of your Fujitsu air conditioning system. If the PCB is faulty or malfunctioning, it can lead to the timer light flashing 10 times. A damaged PCB may occur due to electrical surges, excessive heat, or simply wear and tear over time. In this case, contacting a professional technician to inspect and replace the faulty PCB is recommended.
Power Supply Issues
Inadequate power supply or voltage fluctuations can also cause the timer light on your Fujitsu AC unit to blink 10 times. Insufficient power may be due to a faulty electrical connection, a tripped circuit breaker, or power outage in your area. To resolve this, check the power supply to ensure it is stable and compatible with the AC system’s requirements. If necessary, consult an electrician to address any electrical issues.
Refrigerant Leak or Low Refrigerant Levels
A refrigerant leak or low refrigerant levels can trigger the timer light to flash 10 times on your Fujitsu air conditioning unit. Insufficient refrigerant can result from leaks in the system, which may occur in the coils, pipes, or valves. If you suspect a refrigerant leak, it’s crucial to contact a professional HVAC technician who can locate and repair the leak, as well as recharge the refrigerant to the appropriate levels.
Outdoor Fan Motor Malfunction
The outdoor fan motor plays a vital role in dissipating heat from the condenser coils of your Fujitsu AC system. If the outdoor fan motor malfunctions, it can disrupt the cooling process, leading to the timer light flashing 10 times. This malfunction may occur due to motor wear and tear, electrical issues, or debris obstructing the fan blades. To address this issue, it’s advisable to consult a professional technician who can assess and repair the fan motor.
Sensor Malfunction
Another possible cause of the timer light blinking 10 times is a malfunctioning sensor in your Fujitsu AC unit. Sensors are responsible for detecting the temperature and humidity levels, allowing the system to adjust accordingly. If a sensor malfunctions or becomes faulty, it can disrupt the unit’s ability to operate efficiently, triggering the timer light. An HVAC technician can diagnose the sensor issue and replace it if necessary.
System Overload
If your Fujitsu AC system experiences a system overload, it can trigger the timer light to blink 10 times. A system overload may occur due to excessive heat, clogged air filters, or blocked airflow. It’s crucial to regularly clean or replace the air filters and ensure proper airflow to prevent system overload. Additionally, keeping the surrounding area clear of obstructions can contribute to the efficient operation of your AC system.
Internal Error Codes
Fujitsu air conditioning systems are equipped with internal error codes to indicate specific issues within the system. When the timer light blinks 10 times, it could be signaling an internal error code related to a particular component or function. Consulting the user manual or contacting Fujitsu support can provide you with valuable insights into the specific error code and its corresponding resolution. Following the recommended steps can help you address the internal error and resolve the timer light flashing issue.
Understanding the causes behind the timer light flashing 10 times on your Fujitsu air conditioning unit is essential for troubleshooting and resolving any issues. By identifying the root cause, you can take appropriate actions, whether it involves inspecting connections, repairing or replacing faulty components, or addressing power supply or refrigerant issues. If you encounter any difficulties or are unsure about the troubleshooting process, it’s always best to seek professional assistance to ensure the safety and efficient functioning of your AC system.
