Troubleshooting
If a connector is in poor contact,
insert it securely.
If an input or output cable of the
main control board is not
properly connected, reconnect
the cable terminal.
If there is dust, use a brush or
compressed dry air to remove
dust from various electrical
components, control
components, SPDs, and voltage
detection boards.
If a board has aged, replace it.
If a contactor does not open or
close smoothly, replace it.
