E49 - LP alarm

YES

Correct it.

YES

Is the low pressure sensor

correctly connected?

Check the value on the low

pressure sensor, via indoor

unit, in: (1) stationary

compressor, (2) compressor

operation.

Is the value around 0 MPa, without

significant change, both in states

(1) and (2)?

Check the insulation resistance on

the low pressure sensor.

Is the resistance greater than 100

ohm at DC 500 V?

Connect a pressure gauge to the

low pressure pipe and measure in
state (1). Compare with the value

shown on the indoor unit.

Replace the low pressure

sensor.

Is the difference less than 0.2 MPa?

Advance to checking the refrigerant

circuit on the next page.

Connect a new low pressure

sensor to the control PCB and

position it open in the atmosphere.

Is the pressure 0 MPa in the indoor

unit?

Replace the control PCB.

Replace the low pressure

sensor.
