Compressor Damage Alarm

Error Code

E6

Applicable

Models

REYQ-T

Method of Error

Detection

Determine the symptom to be error by detecting the revolutions of the compressor and pressure values detected by the high and low pressure sensors, and further making a comparison between a theoretical current value of the compressor calculated from parameters detected and an actual current value detected by the power transistor.

Error Decision

Conditions

When a state in which the actual current value of the compressor is abnormally high (by 130% or more) compared to the theoretical current value continues for a period of 30 minutes.

∗ In case of a system with multi outdoor units, the system will return an alarm if there is any operational unit other than that applicable to “E6” or determine to be error if not.

Supposed Causes		Defective compressor Defective high pressure sensor
		Defective low pressure sensor
		Defective control PCB
		Defective inverter PCB

Troubleshooting

Replace the control PCB (A1P).

Replace the inverter PCB.

Replace the inverter compressor.

Note: ∗1.Make a comparison between voltage measured by the pressure sensor and that read by the pressure gauge.

(The pressure sensor makes measurement of voltage at its connector block to convert it to pressure. CHECK 12 )
