Check the power to the oven. Ensure it's plugged in securely to the power source. Also, check the stove’s circuit breaker to see if it's been tripped, and if so, reset it by flipping the switch completely off and back on again. If the residence uses fuses, check the fuse box to see if the oven’s fuse has blown out, and if so, unscrew the fuse and replace it. If there are no problems with the power connection, proceed with the following repair steps.
Check the pilot light to see if it's lit. Depending on the model of your Lady Kenmore oven, the pilot light may be located below the bottom shelf of the oven cavity. Remove the bottom panel to access the pilot light. On some models, you may also need to remove an additional metal plate -- known as the flame spreader -- before you can see the pilot light.
If the pilot light is not on, remove any greasy or burned food in the area with a damp cloth. Then use a straight pen or extended gem clip to clean out the pilot light’s opening.
Place the bottom shelf back in the oven.
Disconnect the oven from its power source or cut off the stove’s circuit breaker -- or shut off the fuse if applicable. This is a safeguard against getting burned, electrocuted or starting a fire.
Check the oven knob to see if it needs adjusting. Remove the knob by pulling it toward you. Turn the knob over and look on the backside. There's a plate on the backside with a screw and either an arrow or a plus and minus sign. You may need to use a flashlight if you can't see the markings on the knob.
Increase -- or decrease, as desired -- the oven temperature on the knob’s screw, using a small flat-head screwdriver. Turn the screw counterclockwise to increase the temperature, or clockwise to decrease the temperature.
Place the knob back on the oven and reconnect the oven to its power source.
