4.1.16 Low-voltage Power Supply PCB (1) Remove screw "a" and take off the low-voltage insulator sheet. (2) Remove screws "c" and "d" to release the grounding wire and power inlet support, respectively. (3) While pulling the right rear of the main cover (placed upside down) outwards to release the ON/OFF switch, lift up the power inlet support. (4) Remove screw "b." (5) Slightly lift up the low-voltage power supply PCB and disconnect the low-voltage power harness and heater harness (of the blue and brown wires).
