Basic Troubleshooting Steps (After Identifying the Error)

After using the error code chart, you may be able to attempt some basic troubleshooting steps:

1. Power Cycle the Unit: Turn off the unit and the circuit breaker that supplies power to it. Wait a few minutes, then turn the breaker and the unit back on. This can sometimes clear minor errors.

2. Check Air Filters: A dirty air filter can restrict airflow and cause performance issues. Clean or replace the air filter as needed.

3. Inspect the Outdoor Unit: Make sure the outdoor unit is free from obstructions (leaves, snow, debris) that could be blocking airflow.

4. Verify Wiring Connections: Carefully inspect the wiring connections to both the indoor and outdoor units. Make sure the wires are securely connected and not damaged.

5. Consult the User Manual: Review the troubleshooting section of your Daikin user manual for more specific guidance.

While some problems can be resolved with basic troubleshooting, it’s best to consult a qualified HVAC technician in the following situations:

• You are uncomfortable working with electrical components.
• The error code indicates a serious issue, such as a refrigerant leak or compressor failure.
• You’ve tried the suggested solutions, but the problem persists.
• You lack the tools or expertise to perform the necessary repairs.
• Your unit is still under warranty. Contacting a professional ensures the warranty remains valid.
