What is Daikin Air Conditioner Flashing Yellow Light?
The occurrence of issues in Daikin air conditioners after some time is inevitable. One of the problems you might encounter is the flashing yellow light error.
This is a complex issue involving various components of the air conditioner such as gas, components, condenser, cooling fan, etc. When the Daikin air conditioner flashes a yellow light on the indoor unit, the device may stop working.

5 Causes of Daikin Air Conditioner Flashing Yellow Light
Numerous factors contribute to the issue of Daikin air conditioner flashing yellow light, specifically:
- The Daikin air conditioner is low on gas or out of gas.
- The signal wire between the indoor and outdoor units is burnt or severed.
- The air conditioner has been in use for an extended period without proper maintenance.
- The cooling fan of the Daikin air conditioner is malfunctioning.
- The machine's condenser is not functioning.

How to fix Daikin air conditioner flashing yellow light
Depending on the specific cause of the yellow light flashing error on the Daikin air conditioner, there are different troubleshooting methods. Specifically:
1. Check the air conditioner's gas
+ Check if the air conditioner is low on, out of, or leaking gas.
+ If so, additional gas needs to be charged. In case of gas leakage, check and reinstall the gas piping.

2. Check the signal wire between the indoor and outdoor units
+ If the Daikin air conditioner continues to flash yellow despite having sufficient gas, inspect the signal wire between the indoor and outdoor units for any breakage or burnout.
+ If there is a break, connect or replace it with another wire of the same cross-section to address the yellow flashing light issue.

3. Check the filter mesh
+ After prolonged use without proper maintenance, dust accumulation on the filter mesh and cooling coil may hinder air intake. Consequently, the Daikin air conditioner may display a yellow light and cease operation.
+ To address the issue, clean the air conditioner, and remember to regularly maintain it every 3-6 months to prevent malfunctions.

4. Check the cooling fan
+ Thoroughly inspect the operation of the cooling fan to ensure normal functioning.
+ If you turn on the air conditioner and the fan doesn't spin, it indicates a malfunction. Check if the connecting electrical wires are severed or exposed.
+ If so, reconnect or replace the wires to restore the normal operation of the cooling fan, resolving the yellow flashing light issue.

5. Verify the operation of the air conditioner's condenser
+ If you've checked the above steps and found no abnormalities, there's a high likelihood that your air conditioner's condenser is damaged or overheated.
+ For this serious issue, self-repair is not recommended without expertise in air conditioning. Contact the manufacturer's warranty center if it's still under warranty or a professional air conditioner technician for the best assistance.
