Controller Function Procedure Results
ERC3 NSC Clock Display Press and hold Clock pad until SET TIME
flashes in the display. Within 30 seconds,
initially press one of the slew up or slew down
pads. Continue to press the appropriate slew
pad(s) until the correct time displays.
Sets the Time-of-Day clock.
ERC3 NSC Bake
Function Press the Bake pad until 0:00 and BAKE is
displayed. Press the slew up pad until 350° F is
displayed, then use the slew up and slew down
pads to set the desired bake temperature (170°
to 550° F ± 25° F).
Oven begins bake operation after a
four-second delay. Bake function will
automatically cease after 12 hours.
ERC3 NSC Broil
Function Press the Broil pad until 0:00 and BROIL is
displayed. Use the slew up and slew down
pads to enter the appropriate broil temperature
range (LO or HI).
Oven begins broil operation after a four-
second delay. Broil function will
automatically cease after 12 hours.
ERC3 NSC Off/Cancel Press the Off/Cancel pad. Cancels all oven functions except the
timer and clock.
