Mitsubishi AC Unit is Blinking Lights
Your Mitsubishi indoor unit blinking lights is a self-diagnosis feature signaling a potential issue. Start by checking the bottom louvre’s clasp, ensuring it’s secure. Loose clasps often cause the bottom lights to blink. For further troubleshooting, identify which LED light flashes and how many times, then consult your owner’s manual for a step-by-step guide. Electrical issues may require an electrician’s expertise.
Mitsubishi Mini Split is Leaking water.
A leaking Mitsubishi mini split suggests a clog in the condenser drain line. To address this, remove the unit, clean the pipes to eliminate blockages, and splash the entire piping system with water. Consider hiring an aircon servicing expert to ensure optimal performance for a thorough cleaning.
Mitsubishi Air Conditioner is Blowing Hot Air
Check the air filter and thermostat settings to see if your Mitsubishi AC blows hot air. A dirty filter may be the culprit. If the issue persists, contacting a licensed service provider like Socool is recommended for a proper diagnosis and resolution.

Reset your Mitsubishi AC by turning it off, plugging the power cord, and flipping the circuit breaker connected to your air conditioner. Switch the breaker back to its original position after waiting 30 seconds to a minute. Power on your air conditioner, and the reset should be complete.
