Daikin Cora model split systems are known for their efficient operation and user-friendly
features, but like any complex machine, they can develop problems from time to time. In this
blog post, we’ll go over some of the most common issues that users experience with Daikin
Cora model split systems, along with step-by-step troubleshooting guides to help you resolve
these issues and get back to enjoying your climate-controlled environment. Please note that this
is a guide yo give you an understanding of what is required and in most cases requires a
licensed technician
- Airflow Issues
One of the most common issues that users face with their Daikin Cora model split system is
airflow problems. If you notice that your system’s airflow has decreased or stopped altogether,
there are a few things you can do to troubleshoot this:
Step 1: Check the air filter. A dirty air filter can restrict airflow, so it’s essential to check and
replace the filter if necessary.
Step 2: Check the vents. Make sure that nothing is blocking the vents, such as furniture or other
objects. Also, ensure that the vents are open and not closed.
Step 3: Check the outdoor unit. If the outdoor unit has debris, such as leaves or sticks, it can
obstruct airflow. Clear away any debris from the outdoor unit. - Refrigerant Leaks
Another common issue that users experience is refrigerant leaks. A refrigerant leak means that
the system is losing refrigerant over time, causing the AC to stop producing cold air. Here’s how
you can troubleshoot this issue.
Step 1: Check for ice build-up. If there’s ice build-up on the evaporator coil, it may be due to a
refrigerant leak. Turn the AC unit off and let it defrost for a few hours. Once it’s defrosted, check
for any leaks.
Step 2: Check the unit’s pressure levels. If the refrigerant levels are low, it’s due to a leak. You
can use a refrigerant gauge to check the pressure levels (must be done by licensed technician).
Step 3: Inspect the copper pipe joints. Check the copper pipe joints for refrigerant leaks. Apply
soapy water to the pipe joints and look for bubbles. If there are bubbles, it means that there’s a
refrigerant leak (must be done by a licensed technician). - Sensor Malfunction
Another issue that users experience with their Daikin Cora model split system is sensor
malfunctions. If the system’s temperature or humidity sensors stop working, it can cause the unit
to malfunction. Here’s how you can troubleshoot this issue:
Step 1: Check the sensors. Locate the sensors and ensure they’re not covered by anything,
such as curtains, furniture, or other objects.
Step 2: Clean the sensors. Dirt, dust, and debris can cause the sensors to malfunction. Use a
soft cloth to clean the sensors gently.
Step 3: Replace the sensor. If the sensor is damaged, you may need to replace it. You can
contact a technician for help with this. - Fan Motor Malfunction
If the outdoor unit’s fan motor isn’t working correctly, it can cause the air conditioning system to
stop cooling. Here’s how you can troubleshoot this issue:
Step 1: Check the fan blades. Ensure that the fan blades are not obstructed by any debris, such
as leaves or twigs.
Step 2: Check the fan motor. Turn off the power to the AC unit and check the fan motor for any
damages or issues (must be done by a licensed technician).
Step 3: Replace the fan motor. If the fan motor is damaged or not working, it will need to be
replaced. Contact a technician for assistance with this (must be done by a licensed technician).
Conclusion
In conclusion, Daikin Cora model split systems can experience a range of issues, from airflow
problems to sensor malfunctions and refrigerant leaks. However, with the troubleshooting
guides we’ve provided, you can diagnose and fix many of these issues yourself. Remember to
keep your system maintained, replace the air filter regularly, and contact a technician for further
assistance if needed. By following these steps, you can keep your Daikin Cora model split
system running smoothly and comfortably.
