SERVICE
MAIN CONTROL
The main control board is very robust and is rarely the
cause of system issues. It is important to fully diagnose
the board for any suspected failures before attempting to
remove the board for replacement or service. Follow the
guidelines below to fully test and diagnose the main
control.
Power Fault
If the unit does not (or seems to not) power on, follow the
flow chart below to help diagnose the issue. Before
beginning it is important to first verify the unit is not
simply set to sabbath mode.
ALL ERRORS
The All Errors option keeps record of any system errors.
When an error occurs it is recorded to all errors. The
number next to the error indicates the number of recorded
instances. Errors in the log may not be currently active.
The error log memory is non volatile and is persistent
should power be lost and restored to the unit. See below
for a list of logged errors and their respective descriptions.
