2.1.12 Replacing O.U. main PCB
1. Remove the front cover and upper cover following “2.1.2 Removing the front cover and upper cover”.
2. Remove the side electrical box cover following “2.1.3 Removing the Side cover and Side Electrical box cover”.
3. Remove the electrical box as shown following “2.1.10 Removing the electrical box”.
Remove all terminals from the O.U. main PCB and disconnect the PFC inductor terminals, compressor terminals, the input
power cable, and the earth terminals.
All terminals are located as shown below, and the terminals which need to be inserted and disconnected during the
replacement are marked in red.
Note: When removing the PFC inductor terminals, the wiring harness terminals have their own latches which can be removed
