There are 3 types of failures associated with the cooktop. The description of these failures and the impact they will have on the rest of the cooktop are
listed in the following.

Failure - Type 1

Failure type 1 comes from the power control board. This failure will affect only one burner. The user may continue to use the other burners.

Failure - Type 2

Failure type 2 usually comes from the power control board (there could be some exceptions). These failures affect all burners associated with that power
control board; the user may continue to use the burners that belong to the other power control board.

Failure - Type 3

Failure type 3 comes from the User Interface. This failure disables the entire cooktop. When this type of failure occurs, all the burners are switched Off by
the User Interface.
