Does any foreign
material intervene in rotational area
of fan propeller?
NO
Does the
fan rotate smoothly when turned
by hand?

Remove foreign material.
Replace fan motor.
If resistance between

1k
Ω
or lower, it is faulty.
Check power supply
voltage.
Replace faulty fan motor
and control PCB.
Replace fan motor (If
anomaly persists after
replacing fan motor, replace
control 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 (FMo1)
drops to 100min
-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 5 times within
60 minutes after the initial
detection.
4. Presumable cause
• Defective outdoor control
PCB
• Foreign material at rotational
area of fan propeller
• Defective fan motor
• Dust on outdoor control PCB
• Blow fuse
• External noise, surge
Note: When E48 error occurs, in almost cases F2 fuse (4A) [Model 71:F3 fuse (2A)]on the outdoor control 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 control PCB ( or fuse) is replaced,, another
trouble (*1) could occur. Therefore when fuse is blown, check whether the fan motor is OK or not.
After confirming the fan motor normal, check by power ON. (Don't power ON without confirming the fan motor normal.)
*1 The error which does not seem to relate E48 may occur like as “
WAIT
”, Stay OFF of LED on outdoor control PCB, inverter
communication error (E45) and etc.
