Cause : in case it senses that door is open for more than 1 hour.
Check point : F/R door is opened or not.
8) “C1” error
Cause : in case comp. works for over 3 hours when FD-S or RD-S temp. is over 23
℉
Check point : Refrigerant leakage.
11) “r3” error
Cause : in case defrosting return is done by time limit of 50 min
Check point : Measure the resistance between both terminals of the Fridge defrost heater.
(Assembled with evaporator)

13) “Communication error between MPCB and FCP
Cause : Communication data problem between MPCB and FCP more than 30 seconds.
Control :
At test mode :
1) "Er CE“ : Not received he data at FCP, because Tx/Rx communication line disconnection
or other problems(MPCB – FCP) or
Tx
communication line is
disconnection(MPCB)
2) " cE" : Not received the data, because of Rx
communication line(at MPCB) is
disconnection or other problems
How to reset : MPCB - FCP Auto clear when communicating normally
