How to troubleshoot Mitsubishi Aircon Error Code?

1. Identify the issue with the aircon.


Is the Aircon cold? Are your Mitsubishi Starmex Aircon lights blinking? Blinking lights indicate Mitsubishi Aircon Error Codes. If the lights are blinking, proceed with the next step.

2. Identify if it is a multi split or single split unit.


If this is a multi split unit, find out how many indoor units that your Mitsubishi Starmex Aircon lights are blinking. For example, if this is system 3 but there is only one unit showing Mitsubishi Aircon error code, the problem is likely due to parts defect in that particular Mitsubishi indoor unit instead of the outdoor unit. On the other hand, if there are multiple units showing error codes, the outdoor unit is likely faulty instead. Typically the price for repair of the indoor unit is much cheaper than that of the outdoor unit.

3. Prepare and find out the model number of the indoor and outdoor unit which can be found here.
