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.
