Trouble shooting 43
OUTDOOR UNIT Error Method:
Compressor 2 Error
Indicate or Display:
Detective Actuators:
Current sensor 2 (for constant speed
compressor)
Detective details:
"Protection stop by "current sensor value 0.1A continued for within 5 hours
during compressor ON command"" generated 2 times
Forecast of Cause :
1. Main PCB to magnetic relay (for constant speed compressor) wiring disconnection, open
2. Compressor power supply system wiring disconnection, open (terminal to magnetic Relay
for constant speed compressor) to constant speed compressor)
3. Magnetic Relay (for constant speed compressor) defective
4. Current sensor 2 (current sensor for constant speed compressor) to Main PCB wiring disconnection,
open
5. Current sensor 2 (current sensor for constant speed compressor) defective
6. Main PCB defective
7. Compressor 2 defective (winding open, protector operated)
Check Point 1 : Check the wiring connection state (main PCB to magnetic Relay (for
constant speed compressor))
OK
Check Point 2 :
Compressor Power supply system (terminal to magnetic Relay (for constant
speed compressor) to constant speed compressor) wiring connection state
OK
Check Point 3 : Check Magnetic Relay (for constant speed compressor)
Magnetic relay (for constant speed compressor) operation check
(Refer to "Sarvise Parts Information 13")
OK
Check Point 4 : Check the wiring connection state (current sensor 2 (current sensor
for constant speed compressor) to Main PCB
OK
Check Point 6 : Main PCB check
OK
Check Point 7 : Replace compressor 2
Compressor 2 replacement
OK
Check Point 5 :
Check the current sensor 2 (current sensor for constant speed compressor)
Current sensor 2 (current sensor for constant speed compressor) check
(Refer to "Service Parts Information 7")
Connector and wiring connection state check
Cable open check
Wiring connection state check
Cable open check
Outdoor Unit : E. 92. 1
Indoor Unit : Operation LED 9 times Flash, Timer LED 15 Times Flash,
Filter LED Continuous Flash.
Error Code : 92
Chack Main PCB. (Refer to "Sarvise Parts Information 4")
>>If replace Main PCB, Refer to 06-03 page Main PCB removal.
04-51
Connector and wiring connection state check
Cable open check
After fixing the problem and for canceling the Error, Error Reset (F3-40) will be required after power reset
