Step-by-Step Guide to Reset a Mitsubishi Aircon Error Code

If your Mitsubishi aircon displays an error code, follow these steps to reset it:

1. Turn Off the Aircon

Start by switching off the air conditioner using the remote control. If the remote control is unresponsive, locate the power button on the indoor unit and press it to turn off the system.

2. Disconnect the Power Supply

Unplug the aircon unit from the power source or turn off the circuit breaker connected to the aircon. This step is essential to reset the system and clear the error code.

3. Wait for 5-10 Minutes

Allow the aircon system to fully discharge residual power by keeping it unplugged for at least 5-10 minutes. This helps reset the internal circuitry and may resolve minor software glitches.

4. Reconnect the Power Supply

After waiting, plug the aircon back into the power outlet or turn on the circuit breaker.

5. Turn On the Aircon

Use the remote control or the power button on the indoor unit to restart the air conditioner. Check if the error code has disappeared.

Set the desired temperature and mode (cooling, fan, or dry) and observe the system for any unusual behavior. If the error code persists, further troubleshooting or professional servicing may be required.
