Power Transistor Check
Warning: Never touch any live parts for at least 10 minutes after turning off the circuit breaker.
If unavoidably necessary to touch a live part, make sure the power transistor's supply voltage is below 50 V using the tester.
For the UVW, make measurements at the Faston terminal on the board or the relay connector.
Power transistor's supply voltage is below 50 V?
Measurements made at the Faston terminal on the board or the relay connector?
Sign off on the power transistor check
Turning Speed Pulse Input Check
<Propeller fan motor> Check
Voltage of 320±30V is being applied
Stop the operation first and then the power, and disconnect the connector S70
DC voltage between pins 4 and 7
With the system and the power still off, reconnect the connector S70
Turn of the fan motor with a hand, and make sure the pulse (0-15 V) appears twice at pins 1 and 4
Is the fan motor protection fuse blown out?
If the fan motor protection fuse is blown out, the outdoor-unit fan may also be in trouble. Check the fan too
If the voltage in Step (2) is not applied, it means the PCB is defective. Replace the PCB
Sound Blanket Removal
Warning: Be sure to wait 10 minutes or more after turning off all power supplies before disassembling work.
1. Remove the right side panel
Remove the outer panels and plates.
Remove the electrical box.
1 Loosen the 3 screws on the right of the right side panel.
2 Loosen the 2 screws on the back.
3 Remove the packing. There is a hook on the back.
4 Pull up the right side panel.
5 Loosen the 2 screws of the wiring fixture.
Elecrical Box Removal
Warning: Be sure to wait 10 minutes or more after turning off all power supplies before disassembling work.
1. Disconnect the connecting wires

1 Inside structure.
2 Disconnect the connecting wires.
Connecting wires of the A, B, C, D port
(1) - Black Power supply
(2) - White Power supply
(3) - Red Transmission
Capacitor Voltage Check
Warning: Check the main circuit for short-circuit before proceeding
Main circuit checked for short-circuit?
Warning: Be careful never to touch any live parts.
Measure the voltage according to the model's drawing
Upload a photo of the voltage reading
