When the oven is o, there are no lights or indicators.

Start Up:

Press the Cook/O/Cool Down rocker switch to the "Cook"
position. The green lamp will light indicating the oven is
powered in cook mode.
The oven will begin to heat to the temperature set on the
thermostat dial. The amber lamp will light indicating the heat
is active. As the heat cycles on and o to maintain the set
temperature this light will go on and o accordingly.
The door must be closed for the oven to operate in cook
mode. Opening the door will cause the heat to stop. The
motor and fan will shut o. This is a safety feature.

Lights:

The oven lights are activated by pressing the light switch on
the control panel. This is a momentary switch and the lights
will stay lit as long as this button is held in the on position.
Lights will work whenever there is electrical power connected
