Mitsubishi Aircon Error Code
The electric brand Mitsubishi was mostly popular in Singapore when it came to buying an air conditioner. They get their name from keeping perfect cooling for long and low energy consumption. But just like any other, even a Mitsubishi aircon is not completely immune to error codes when something is wrong.
Such strange pop-up aircon panel cases are quite odd, enough for customers to call us to inquire about error codes and what those codes mean: how can they be fixed? To simplify matters for you, we have developed a nifty guide to the Mitsubishi aircon error codes and what you should do about them.

What Are Mitsubishi Aircon Error Codes?
These are the predefined diagnostic signals. Whenever a fault is detected by your Mitsubishi air conditioner—whether with temperature sensors, wiring, or drainage—the system will somehow malfunction and show a code on the remote controller or an indicator light.
Instead of merely guessing, these codes let technicians see where the actual problem occurs.
Common Mitsubishi Aircon Error Codes & Their Meanings
Here are some of the most frequently seen error codes:
- P1 – Indoor unit coil sensor problem
- P2 – Outdoor unit sensor fault
- P4 – Communication error between the indoor and outdoor units
- E6 – Drainage issue (water not draining properly)
- U4 – Power supply issue or wiring error
⚠️ Keep in mind that the exact codes may vary depending on your Mitsubishi model. Always refer to your unit’s manual for detailed descriptions.
