Troubleshooting Mitsubishi inverter air conditioners can be a daunting task, but understanding how to check the error codes is the first step in resolving any issues. This comprehensive guide will walk you through the process of identifying, displaying, and interpreting Mitsubishi inverter error codes, equipping you with the knowledge to diagnose and address problems effectively.
Identifying the Error Code
The first step in checking the Mitsubishi inverter error code is to locate the upper or left operation indicator lamp on the indoor unit. If this lamp is flashing, it indicates that an error has occurred. To identify the specific error code, count the number of times the lamp flashes between the delay periods.
Each error code is represented by a unique number of flashes, allowing you to pinpoint the issue. For example, if the lamp flashes three times, followed by a delay, and then repeats this pattern, the error code is likely “03.”

Once you have identified the flashing pattern, the next step is to display the error code on the handheld remote controller. To do this, follow these steps:
- Ensure that the handheld remote controller is powered off.
- Position yourself within 2 meters (6.5 feet) of the indoor unit, pointing the remote controller at the receiving section.
- Using a fine-tipped object, press and hold the small “CHECK” button on the remote controller.
- While holding the “CHECK” button, continue pointing the remote controller at the receiving section of the indoor unit until you hear a beep and the error code appears on the display.
This process allows you to access the error code information directly from the remote controller, providing a clear and concise way to identify the problem.
Interpreting the Error Code
With the error code displayed on the remote controller, you can now refer to the Mitsubishi error code table to determine the specific issue. Each error code corresponds to a particular problem, such as a sensor failure, compressor malfunction, or communication error.
If the display shows “00,” it indicates that there is no error. However, if any other error code appears, it means that the air conditioner requires inspection and repair. In such cases, it is crucial to stop using the air conditioner, turn off the breaker, and contact your dealer or a certified Mitsubishi technician for further assistance.
