Compressor startup failure
(Models SRC40-60)
1. Applicable model
5. Troubleshooting
Models SRC40-60
Diagnosis
Countermeasure
NO
NO
Is power
supply voltage
OK?
Is
the pressure balance
at starting OK?
NO
NO
Is the
insulation resistance
and coil resistance of
compressor OK ?
Is power transistor
module OK?
Try to startup
several times
Does it start?
NO
NO
Is
the output of inverter
checker OK ?
Compressor does not start at all.
Neither noise nor vibration cannot be heard
Disconnect the outdoor fan motor
connector and try to startup
Does
compressor
startup?
YES
NO
Note: Several times restarting
may resolve it, because migrated
liquid refrigerant in the
compresser is discharged from
the compressor.
YES
YES
YES
YES
YES
Replace outdoor fan motor
Check power supply
voltage
Check refrigerant amount
and refrigerant circuit
Repalce compressor

Repalce compressor
2. Error detection method
If it fails to change over to the
rotor detection operation of
compressor motor
3. Condition of Error displayed
If compressor fails to startup for
42 times
4. Presumable cause
• Outdoor fan motor anomaly
• Outdoor PCB anomaly
• Anomalous power supply
voltage
• Improper refrigerant amount
and refrigerant circuit
• Faulty compressor (Motor
bearing)
Note: Insulation resistance
•
The unit is left for long period without power supply or soon after installation, migrated liquid refrigerant may dissolve in the refrigerant oil in the compressor.
In such case insulation resistance decreases upto several M
Ω
or lower. If the electric leakage breaker is activated due to low insulation resistance,
check followings.
➀
Check whehter the insulation resistance can recover or not, ater 6 hours has passed since power ON.
(By energize the crankcase heater, migrated liquid refrigerant in the refrigerant oil in compressor can be evaporated)
➁
Check whether the electric leakage breake conforms to high-hermonic specifications
(As units has inverter, in order to prevent from improper operation, be sure to use high-hermonic one.)
