Mitsubishi Air Conditioner Error Codes


Mitsubishi Electric Slim A-control

 

EA code - The indoor and / or outdoor unit is not correctly installed. It is necessary to check the interconnection, the electrical circuit. The chain is broken.

 

EB code - Rough installation faults, tripping of protection until tripping.

 

EU code - A startup error message appears for 5 minutes. Turn off the power, de-energize split system Mitsubishi Electric, get the batteries from the remote control. After 5 minutes, collect everything in reverse order.

 

In this case, all settings manually reset to zero and return to the factory settings.

 

e motor is observed.

Error codes for Mitsubishi Electric air conditioners of inverter type.

 

The connection is broken.

 

Code E6 - Signal about the connection error of the outdoor and (or) indoor units, as well as the sensor receiving the signals (signals are not accepted).

 

No signal with a short circuit.

 

Code E7 - Signal on connection error of external and (or) internal transmission blocks

 

No signal with a short circuit.

 

Code E8 - The signal about the error of the sensor operation. It is necessary to check the power supply to the sensor. The chain is broken.

 

Code E9 - Signal of an error in the operation of external and (or) internal connections between the units. The chain is broken. No signal.

 

Code E0 - No signal from the remote control (signal not received). On the remote control, you need to replace the batteries.

 

Code E3 - An error signal. The signal coming from the air conditioner PU is not formed correctly.

 

For correction, look at the EU Code.

 

Code E4 - Check interconnection, integrity of pressure sensors and temperature.

 

Code E5 - Check the mains voltage. The equipment may malfunction.

 

Code EF - Error M-NET, - no signal.

 

It is necessary to check the interconnection, poor connections or breakage of connections.

 

Code Ed - Violations in the signal generation sequence. Stepper searcher fails.

 

To correct the watch the EU Electric Code Mitsubishi Electric, reset the air conditioner settings, set the factory default settings.

 

Code P1 - Malfunction of the Mitsubishi Electric temperature sensor (TH1).

 

Inspect the sensor for mechanical integrity. The hermetic connection of the sensor is destroyed. Closing of the connecting cable and sensor due to the presence of dirt and moisture on them.

 

Code P2 - Indication of indoor unit freezing sensor.

 

Contamination of the indoor unit, insufficient air exchange, which is a consequence of the fact that the indoor unit is frozen.

 

The cause of frostbite is a lack of gas. Unplanned preventive maintenance of the conditioner is necessary.

 

Code P4 - Check drain, drainage, because there was a trigger of the sensor indicating the highest level in the bath. The drain is corked.

 

Code P5 - No draining. Idling operation of the drainage motor is observed.
