All errors of the Power Boards and the Clock Board are displayed using the seven segment digits on
the Clock Board display.
In the double models the upper cavity power board is the master board, the lower cavity power
board is the slave board.
There are two types of fault codes,
A – Alert codes: These are customer errors which can be solved by generally letting the product
cool down, or powering it off then on at the wall. These codes will show the letter A, followed by a
number.
F – Failure Faults: These are generally caused by component failure, and will either be in the User
Interface (UI) or the Power Board (PB).
