5. Using a needle nose pliers, disengage the control board from all
the plastic standoffs by lightly pressing the tiny protruding clip on
each standoff, while simultaneously pulling the simmer board off
the standoff (see Figure 113).

NOTE: Please explore other possible causes before
replacing the simmer control board. Approximately 75%
of all simmer control boards returned to the factory turn
out to be ok.
