What is the A5 Error Code on Daikin Air Conditioners?
According to the error code table provided by Daikin, the A5 error code signifies high-pressure control issues in heating mode and frost protection control in cooling mode.
The A5 error code is most commonly encountered in Daikin Inverter air conditioners, domestic Daikin units, and VRV central air conditioning systems (evaporator units).
How to Check the A5 Error Code on Daikin Air Conditioners
Most Daikin air conditioner models lack a display screen. Hence, when encountering the A5 error code, the device signals users by flashing lights on the indoor unit while ceasing operation.
To accurately diagnose the issue with your Daikin air conditioner, follow these steps:
+ Step 1: Direct the remote control towards the indoor unit.
+ Step 2: Press and hold the CANCEL button for 5-7 seconds until the remote control's screen displays error code 00.
+ Step 3: Press and release the CANCEL button in intervals. When you hear a beep from the indoor unit, it indicates the Daikin air conditioner's error code.
Causes of Daikin Air Conditioner Displaying A5 Error Code
There are several reasons why a Daikin air conditioner may display the A5 error code, but there are four main causes:
+ The outdoor and indoor units have not been cleaned for a long time, with the filters accumulating excessive dust.
+ The refrigerant has run out or is running low.
+ The heat exchange thermistor is damaged.
+ Faulty circuit board in the indoor unit, specifically in the frost prevention system.
How to Fix the A5 Error Code on Daikin Air Conditioners
The A5 error code on Daikin air conditioners is quite common, so you can troubleshoot it at home following these instructions:
+ Step 1: Thoroughly clean both the outdoor and indoor units of the air conditioner, especially the filter.
+ Step 2: Check the refrigerant level of the air conditioner; if it's low or depleted, it needs immediate replenishment.
