What is Daikin Air Conditioner E0 Error?
According to the error code chart provided by the manufacturer for Daikin air conditioners, the E0 error indicates a fault in the protection devices of the outdoor unit. Specifically, it could be due to a faulty high-pressure switch, broken coils, overloaded fan motor, loose connections, or a malfunctioning outdoor unit circuit board.
The E0 error often appears on Daikin ceiling-mounted air conditioners. When the Daikin air conditioner encounters the E0 error, the E0 message will flash on the remote control screen.
Causes and Solutions for E0 Error on Daikin Air Conditioners
For each cause, there is a corresponding solution as follows:
1. Cause and Solution for E0 Error Due to High-Pressure Switch
+ Cause: The high-pressure switch activates when the pressure leaving the compressor is higher than normal, causing the system to shut down. A faulty high-pressure switch triggers the E0 error on Daikin air conditioners.
+ Solution: What you need to do is check the high-pressure switch to see if it is functioning. If not, replacement is necessary to ensure the Daikin air conditioner operates normally.
2. Cause and Solution for E0 Error Due to Overloaded Fan Motor
+ Cause: When the fan motor of the outdoor unit is overloaded, the Daikin air conditioner reports the E0 error. Causes of overloaded fan motor include insufficient air conditioner capacity, high outdoor temperatures preventing heat dissipation, improper outdoor unit placement exposed to excessive sunlight, high or low refrigerant pressure, and faulty or underpowered fan.
+ Solution: Check if the outdoor fan motor is overloaded and still operational. If not, repair or replace the fan motor. Also, inspect the placement of the outdoor unit to ensure it is not exposed to direct sunlight or incorrectly positioned. Additionally, check the air conditioner's refrigerant levels for deficiencies and top up if needed.
3. Cause and Solution for E0 Error Due to Broken or Loose Coil Connections
+ Cause: Coils with loose or broken connections.
+ Solution: Examine the coils for any loose or broken connections. If broken, replace them; if loose, tighten them securely.
4. Cause and Solution for E0 Error Due to Faulty Outdoor Unit Circuit Board
+ Cause: Malfunctioning outdoor unit circuit board.
+ Solution: Conduct a check to see if the circuit board is faulty and still operational. If it has minor damage, repair it; if severe, replace it.
5. Cause and Solution for E0 Error Due to Impact on Outdoor Unit Protection Devices
+ Cause: Outdoor unit protection devices impacted, including temperature sensor at the compressor discharge head, high and low-pressure sensors, and gas return cutoff sensor; temperature sensor on the return line to the compressor.
+ Solution: Use equipment to measure the temperature and pressure of the temperature sensor at the compressor discharge head, high-pressure sensor, temperature sensor on the return line to the compressor, and low-pressure sensor to check if they exceed allowable limits. Simultaneously, check if the gas return line is obstructed. Resolve any issues or malfunctions to ensure normal operation of the Daikin air conditioner.
To troubleshoot the E0 error on Daikin air conditioners, you need specialized tools and knowledge in air conditioning. If you lack understanding of air conditioning and don't have the necessary repair tools, it's advisable to contact Daikin's warranty center or a repair service for assistance and safety assurance.
Some Notes When Using Daikin Air Conditioner to Avoid E0 Error
Some tips when using Daikin air conditioner below will help minimize Daikin E0 error:
