KELVINATOR – ELECTROLUX INVERTER SPLIT SYSTEM Fault codes, blinking codes and repair procedure - Part - 2

KSV 26CRE, KSV 35CRE, KSV 70CRE, KSV 26HRE, KSV 35HRE, KSV 53HRE, KSV 62HRE, KSV 70HRE and  KSV 80HRE Models
Communication Fault

*  Disconnect the main power supply to the indoor unit by means of the isolation switch. After approximately one minute, turn the power supply back on & attempt to operate the unit in “Auto” mode with a set temperature of two degrees above or below the ambient temperature.
If the Communication fault has not cleared:
*  Check for supply voltage at the following points.
• Between the Active -Out & Neutral points on the indoor PCB.
• Between the Active & Neutral points on the indoor terminal block.
• Between the Active & Neutral points on the outdoor terminal block.
• Between the Active & Neutral points on the outdoor PCB.
Note: If all the above checks relating to the supply voltage points have been completed, yet the error code still exists, continue:
* Disconnect the supply power & check the continuity of the COM-U wire from the following
points:
> COM-U terminal point on the indoor PCB.
> To the communication terminal points on the indoor terminal block.
> To the communication terminal points on the outdoor terminal block.
Note: When checking the continuity between the indoor terminal block & the outdoor terminal block, disconnect the COM-U & Active wires on the indoor terminal block, then attach them together. This will create a circuit that can then be tested between the COM-U & Active terminal points on the outdoor terminal block.
Note: If all the above checks relating to the COM-U points have been completed, yet the error code still exists, continue.
* Check the continuity of the reactor. If open circuit, change it.
* If the reactor is okay, replace the outdoor PCB assembly.
H5, Indoor unit.
Yellow LED, Outdoor flashing 10 times.
(IPM Protection)
* Disconnect the supply power to the unit by means of the isolation switch.
* Remove the Blue-U, Yellow-V & Red-W flag terminals from the compressor, then measure the resistance value of each winding from these points.
Note: The resistance value should be the same across any terminal combination.
# If all resistance checks are okay, replace the outdoor PCB assembly.
F3 Indoor unit.
Red LED, Outdoor flashing 6 times.
(Outdoor Ambient Sensor)
F4, Indoor unit.
Red LED, Outdoor flashing 5 times.
(Outdoor Coil Sensor)
F5, Indoor unit.
Red LED, Outdoor flashing 7 times.
(Outdoor Compressor Discharge Sensor)
* Check the Condenser Coil, Outdoor Ambient & Compressor Discharge triple point sensor plug for correct connection.
* Check the continuity of each individual sensor, if anyone of the sensors is open circuit; replace the complete triple connector plug assembly.
Note: If all the above checks relating to the sensors & wiring have been completed, yet the error code still exists, replace the main outdoor PCB.
F1, Indoor unit.
(Room Temp Sensor Failure)
F2, Indoor unit.
(Tube Temp Sensor Failure)
* Check the Indoor Ambient & Indoor Tube sensors for correct connection.
* Check the continuity of the relevant sensor, if the sensor is open circuit, change it.
Note: If all the above checks relating to the sensors & wiring have been completed, yet the error code still exists, replace the indoor PCB.
H6, Indoor unit.
(Indoor Fan Stall)
* Check to see if the indoor barrel type fan blade is turning freely.
* Check the evaporator fan motor for correct operation. If the fan motor is not operating check if both three pin AC-Motor connector plugs are anchored correctly to the indoor PCB.
* Check for AC voltage between the Brown & Red wires located on the upper AC-Motor connector plug:
Cooling Mode
Heating Mode
1 speed: 192 Volts AC.
1 speed: 185 Volts AC.
2 speed: 220 Volts AC.
2 speed: 215 Volts AC.
3 speed: 290 Volts AC.
3 speed: 235 Volts AC.
Note: The above AC voltage readings can fluctuate within a range of 10 volts.
* Remove the three pin upper AC-Motor connector plug & check the resistance value from the following points:
> Brown & White (332 ohms)
Note: If the above AC voltage checks are not available, replace the main indoor PCB assembly.
Note: If the above resistance values are not available, replace the indoor fan motor.
L3, Indoor unit.
Red LED, Outdoor flashing 14 times.
(Outdoor DC Fan Motor Malfunction)
* Check the condenser fan for correct operation. If the fan motor is not operating check the three pin DC-Motor connector plug for correct termination to the outdoor PCB.
* With the unit set in heating or cooling mode (depending on ambient conditions) Check for DC
voltage from the points illustrated below, located on the main outdoor PCB.
> Red & Yellow wires: < 13 Volts DC.
> Red & White wires: < 13 Volts DC.
H3, Indoor unit.
Yellow LED, Outdoor flashing 8 times.
(Compressor Overload Protection)
* Check the following points:
> Refrigerant charge.
> Restrictions within the capillary tube.
> Poor air flow across the indoor & outdoor coils.
> Correct operation of the four-way reversing valve.
*  Check the compressor Over Temperature connector plug located on the outdoor PCB for correct termination & continuity to the over temperature protector.
*  Check the over temperature protector located next to the three compressor terminals.
Note: This over temperature protector is “normally closed”.
C5, Indoor unit.
(Jumper Cap Malfunction)
* Check the Jumper Cap for correct termination to the indoor PCB.
Note: If the Jumper Cap is correctly terminated, yet the C5 fault still exists, replace the indoor PCB assembly.
