ACTION TO BE TAKEN AFTER IDENTIFICATION OF ERROR

Fault Message E 1 E 2 F 8 F 6 F 1 Action To Be Taken Check room sensor wiring, Change room sensor, Track/ SMD on PCB in series of room sensor. Check coil sensor wiring, Change coil sensor, Track/ SMD on PCB in series of coil sensor. Check motor wires, Feedback wires, Motor Jam, Track burn/ SMD burn in series with feedback signal. Check room sensor wiring, Change room sensor, Track/ SMD on PCB in series of room sensor. Green Led blink Check coil sensor wiring, Change coil sensor, Track/ SMD on along with operation PCB in series of coil sensor. LED Green Led blink Check room sensor wiring, Change room sensor, Track/ SMD on along with operation PCB in series of room sensor. LED Only Green Led blink after 1 min Check motor wires, Feedback wires, Motor Jam, Track burn/ SMD burn in series with feedback signal.

Fault Message F 8 F 6 F 7 H 6 F 2 F 1 C 5 E 6 E 2 E 1 Action To Be Taken Check coil sensor wiring, Change coil sensor, Track/ SMD on PCB in series of coil sensor. Check motor wires, Feedback wires, Motor Jam, Track burn/ SMD burn in series with feedback signal. Check room sensor wiring, Change room sensor, Track/ SMD on PCB in series of room sensor. Check motor wires, Feedback wires, Motor Jam, Track burn/ SMD burn in series with feedback signal. Check coil sensor wiring, Change coil sensor, Track/ SMD on PCB in series of coil sensor.

ODU FAULT MESSAGES Sr No 1 2 Problem Red Light Yellow Light Green Light Outdoor Evaporator Temperature Sensor Malfunction Outdoor Ambient Temperature Sensor Malfunction 5 Blink 6 Blink 3 Over current Protection 5 Blink 4 IPM Protection 4 Blink 5 Communication Malfunction Off Problem Action To Be Taken Check sensor wiring, Connector of Sensor, Change outdoor sensor, Track/ SMD on PCB in series of sensor. Check sensor wiring, Connector of Sensor, Change outdoor Ambient sensor, Track/ SMD on PCB in series of sensor. Check Compressor Wiring for Short Ckt, Room Sensor/ Wiring/ Connector faulty. If fault is permanent after 6 times, Check the PCB for Module Burnt/ Track Burnt/ Any damage. Check the Communication cable between IDU & ODU for Cable Cut/ Loose connection/ Any other High Power cable adjacent to the AC cable. IDU FAULT MESSAGES Action To Be Taken Error Code 1 Jumper Cap Malfunction C 5 Clean & Place connector 04 properly. 2 Indoor Sensor Malfunction FP Check room sensor wiring, Change room sensor, Track/ SMD on PCB in series of room sensor. 3 Indoor Fan Failure H 6 Check motor wires, Feedback wires, Motor Jam, Track burn/ SMD burn in series with feedback signal. 4 IPM Protection H 5 If fault is permanent after 6 times, Check the PCB for Module Burnt/ Track Burnt/ Any damage.

Connector 04 ( C 5 Error In VPS )

WAC Control PCB SMD in series with Room sensor signal.

WAC Power PCB Relays Can Damage Due To: 1 Short Circuit in wiring 2 Wrong Wiring 3 Loose connections at Terminals ( Sparking ) VDR 10 K 561 ( Over-Voltage protector )

F 6 Or H 6 Error in SAC Motor Feedback connector ( 3 Pin) Includes Vcc, Feedback & Gnd. ( Check 5 V between Vcc & Gnd ) Can Be Due to: 1 Motor Wires Cut 2 Feedback wires cut 3 Motor Jam ( Feedback signal not received) 4 Track Burn on PCB ( Feedback not reach to MICON 5 Faulty Connector of Feedback.
