Mitsubishi Electric Air Conditioner Error Code P1

The P1 error code on Mitsubishi Electric air conditioners indicates a problem with the unit’s drainage system. This error typically occurs when the condensate drain is blocked or the water level in the drain pan is too high. As a result, the air conditioner may stop functioning properly, leading to longer cooling times, increased humidity levels in your space, and potential water damage if the issue is not addressed promptly. Users may also experience safety risks due to water overflow, which can lead to electrical hazards or mold growth in the surrounding areas.

Common Causes of Error Code P1

• Blocked condensate drain line
• Dirty or clogged air filters
• Improper installation or leveling of the unit
• Faulty float switch
