Midea
10 codesWater collection tray full alarm — unit emits 8 beeps and displays P1 when tray reaches maximum water level.
Indoor temperature sensor error — the indoor temperature sensor is not functioning properly.
Outdoor temperature sensor error — the outdoor temperature sensor is not functioning properly.
Communication error between indoor and outdoor units — the indoor and outdoor units cannot communicate properly.
Condenser temperature sensor error — the condenser coil temperature sensor has malfunctioned (on some models).
Display panel communication error — the control panel cannot communicate with the main circuit board.
Room temperature sensor error — the indoor temperature sensor has malfunctioned.
Evaporator temperature sensor error — the evaporator coil temperature sensor has malfunctioned.
Refrigerant leakage detection malfunction — the refrigerant leak detection sensor has malfunctioned (on some models).
Bottom tray is full — water collection tray has reached maximum capacity and unit has stopped cooling/dehumidifying.
Black & Decker
7 codesIndicates a fault with the room temperature sensor.
Indicates a fault with the condenser temperature sensor.
Indicates a water drainage issue detected in cooling mode.
Indicates a fault with the evaporator temperature sensor.
Indicates a water drainage issue detected in heating mode (for models with heat feature).
Indicates a noise detection issue, signaling potential overheating or malfunction.
Indicates that the remote control is not functioning properly with the unit.
Sanyo
5 codesError related to branch tubing temperature sensor or outdoor temperature sensor malfunction.
Indicates system detected fault (e.g., compressor overtemperature, faulty sensor, electrical component issue).
Overheating detected — internal temperature too high.
Drain error — water is not draining from the unit.
Indicates system was initialized and turned off but is now back on, possibly due to auto-fault detection.
Frigidaire
4 codesSensor failure — a sensor in the unit has failed and the system cannot operate properly.
Internal memory chip failure — the control board's memory has failed and the unit cannot operate properly.
Communication malfunction of main control board — the control board is not communicating properly with other components.
Indoor ambient temperature sensor is open/short circuited — the temperature sensor is not functioning properly.
