E59 - Inverter error

(1) (2)

(1)

YES

Is power source voltage OK?

YES

Replace control PCB

Is the voltage 15VDC detected

between

䐠

and

䐡

of CNI3 on

the control PCB side?

Is the voltage 15VDC detected

after disconnecting the

connector of outdoor fan motor?

Can the compressor startup?

Is the pressure balance at

starting OK ?

Is the insulation resistance and

coil resistance of compressor OK?

Is the power transistor module

OK ?

Is the inverter output OK ?

Try to startup several times

Can start ?

Check power source.

Replace Inverter PCB

If not solved yet, replace

noise filter PCB as well.

Replace the outdoor

fan motor.

OK.

Check refrigerant amount

and refrigerant cir cuit.

Replace the compressor.

Replace the inverter PCB.

Replace the compressor.

Note (1): Under anomalous conditions,

the voltage becomes less than 14VDC.

Note (2): How to check voltage at

CN13

⇒

See E51.

Note: Several times restarting trial may

make a recovery from startup failure,

because liquid refrigerant migrated in

the compressor could be discharged

during several trial.
