E48
Outdoor fan motor anomaly
(Models SRC40-60)
1. Applicable model
5. Troubleshooting
Models SRC40-60
Diagnosis
Countermeasure
YES
NO
Does any
foreign material intervene
in rotational area of fan
propeller?
NO
Does the
fan rotate smoothly when turned
by hand?
NO
Is DC308~336V
detected between (CNFAN
(black)-
(red)) of fan motor
connector?
Is F3 (250V1A) fuse blown?
Is normal state restored?
YES
YES
NO
YES
NO
YES
Power supply reset
Remove foreign matter.
Replace fan motor.
If resistance between
(FG):blue -
(GND):black
is detected 1k
:
or lower, it
is faulty.
Check power supply
voltage.
Replace faulty fan motor
and outdoor PCB.
Replace fan motor (If
anomaly persists after
replacing fan motor, replace
outdoor PCB.)
Malfunction by temporary
noise
2. Error detection method
Detected by rotation speed of
outdoor fan motor
3. Condition of Error displayed
When actual rotation speed
of outdoor fan motor drops to
75min
-1
or lower for 30 minutes
continuously, the compressor
and the outdoor fan motor stop.
After 3-minutes delay, it starts
again automatically, but if this
anomaly occurs 3 times within
60 minutes after the initial
detection.
4. Presumable cause
• Defective outdoor PCB
• Foreign material at rotational
area of fan propeller
• Defective fan motor
• Dust on outdoor PCB
• Blown F3 fuse
Note: When E48 error occurs, in almost cases F3 fuse (1A) on the outdoor PCB is blown. There are a lot of cases that fuse is blown and E48 occurs
due to defective fan motor. And even though only the outdoor PCB ( or fuse) is replaced,, another trouble could occur. Therefore when fuse is
blown, check whether the fan motor is OK or not.
