Set the time of day, if the oven does not operate. Change or enter the time by pressing the "Clock" button, then press the "up" or "down" buttons to adjust the clock. To set the countdown timer, press the "Timer On/Off" button. Press the "up" button repeatedly to increase the time in one-minute increments, or hold the "up" button to increase the time in 10-minute increments. Pressing the "down" button sets the timer to 11 hours and 59 minutes. Note that the countdown timer does not actually turn the oven off after it reaches zero.
Change the bulb, if the interior light does not come on. Buy a 40-watt appliance bulb from any store that sells household light bulbs. The general installation instructions for many oven models include disconnecting the electrical power, removing the glass shield and unscrewing the burned-out bulb. Screw in the new bulb, replace the glass shield and reconnect the power. Consult your owner's manual for specific instructions.
Press the "Clear" button if the F1, F3 or F9 error codes appear on the display screen. This usually means that there was a momentary power failure or fault in the home. Everything should be okay after power is restored, such as after a lightning storm. However, if these error codes reappear, there is another fault issue with the oven and you need to contact an appliance service technician.
Wipe up excess spills in the bottom of the oven to reduce the presence of flames and smoke in the compartment. Spills are a normal part of baking and cooking, but the buildup can create serious eye and nose irritation when it starts to burn. Also, wipe up spills before setting the self-clean cycle, because the extreme heat will only make the flames and smoke worse. Generally, the natural gas flame is not the source of these problems.
