A kitchen range has electric elements or gas burners that provide heat to the cooktop and oven. Most gas ranges also have some electric features, such as a clock and lights, and sometimes an electric pilot.
Be sure the power cord and terminal block on a freestanding range aren't defective. Replace them if necessary.
Unreliable Oven Temperature
Unreliable oven temperature is a common complaint. The thermostat that maintains oven temperature is part of the oven control. If the thermostat fails, have the entire control replaced. But if it's only out of calibration, you may be able to adjust it.
The cooktop heating elements of most modern electric ranges simply plug into a receptacle, allowing for easy cleaning or replacement. The same is true of the baking and broiling elements.
Safety Tip: Turn off the power to the range or, if necessary, to the entire circuit before making any electrical checks or repairs.
Whether on the cooktop or in the oven, a gas burner that doesn't work may lead you to a pilot that has gone out. Pilots may be gas or electric (in the latter, a spark ignites the gas). Both types are easily relighted (see your owner's manual). A gas pilot that continually goes out calls for cleaning and adjusting and perhaps gas company help.
Keeping the Right Flame
The flame of a cooktop or oven burner should be a bright, steady blue. If it's not, you'll need to change the air-gas ratio by adjusting the burner's air shutter.
CAUTION: If you smell gas and the pilots are lighted, get out of the house immediately and call the gas company from a neighbor's house.
Be sure to turn off the power to a gas range if you'll be working on its electrical parts.
