Electric Oven
It's stopped completely
If your range/oven doesn't seem to work at all, check these:
Fuse/circuit breaker
Main wiring
Range/oven wiring
Fuse/circuit breaker
Check to see if power is getting to the range/oven. Does anything turn on--even a light? If not, check for a blown fuse or tripped circuit breaker.
Main wiring
Often the main wiring connection from the house, at the range/oven, gets burned and so breaks the connection. Then you may have to replace the power cord to the range/oven, and the terminal block that the wire is attached to.
Range/oven wiring
There may be a broken or burned wire at the back of the range/oven. If you repair any of the wires, use only proper appliance-grade wire and wire connectors.
It won't bake
Usually, when an oven won't bake, it's because the bake element is burned out. The bake element is the black, pencil- thick tube at the bottom of the oven. When the oven heats, the element glows red. This element has an expected life-span of several years. It may last for only one; it may last for many more. When the element burns out, you need to replace it.
It bakes poorly
Here are two instances of when food "bakes poorly:"
When the food you're baking is done on top but not on the bottom--or when baking just takes far too long to finish--the bake element may be burned out.
 
You may get fooled into thinking it's working, because the oven is hot inside. But many electric ovens use the broil element, too, during the preheat and bake cycles. So the food may be getting heated only by the broil element, which causes poor baking results.
 
If the bake element is burned out, replacing it should solve the problem. Otherwise, you need to further troubleshoot the oven's electrical system to locate the defective wire or component.
When the temperature is consistent but too high or too low, it could be one of several different things. First check to see if the thermostat sensing bulb has come loose from its holder. It could be lying on the floor of the oven or resting on the heating element. This would cause the oven to not heat correctly.
 
If the thermostat bulb is not dislodged, it's likely that the thermostat or sensor is either mis-calibrated or defective.
 
Electronic ovens with a digital display use a sensor to monitor oven temperature. To solve temperature problems for these models, you may need to replace the sensor. On some digital-display models, you can calibrate the temperature using the key pad. See your operator's manual for details.
 
Ovens without a digital display often use a mechanical system for controlling temperature. On many of these units, you can remove the thermostat knob and adjust the knob itself to more accurately represent the actual setting of the thermostat.
 
If, when you remove the knob, there's a screw on the back of it with a small calibration plate, you can loosen the screw, adjust the plate, then tighten the screw again. If the knob isn't adjustable, and the oven temperature is off by more than 30 to 40 degrees, you need to replace the thermostat to solve the problem.
It won't broil
Usually, when an oven won't broil, it's because the broiler element is burned out. The broiler element in an electric oven is the black, pencil-thick tube at the top of the oven. When the broiler is on, the element glows red. This element has an expected life-span of several years. It may last for only one; it may last for many more. When the element burns out, you need to replace it.
A burner doesn't work
Heating elements eventually burn out. Sometimes, when an element burns out, you can see that the coil burns in two, or blisters and bubbles.
When your heating element burns out, you have to replace it because they are not repairable. If, when the heating element burns out, the infinite switch that controls it also fails, you have to replace it too. Also see the "A burner works only intermittently" section, next.
A burner works only intermittently
If one of your burner heating elements works only intermittently, it's probably because of worn or bad contacts in the receptacle that the element plugs into. On most electric ranges, you can remove the element by lifting it up several inches and firmly pulling it away from its attachment (receptacle). Read your owner's manual to learn the correct technique for your range.
If, after removing the element, you see that the ends of the element that were plugged in are pitted, corroded, burned, scarred, or rusted, replace both the element and the receptacle.
I can't adjust the burner temperature
If your burner always heats to "high" when it's on--regardless of how you set the burner knob--the switch contacts are shorted closed. Check the circuit for any other grounds, then replace the switch.
It won't bake or broil
If neither the bake nor the broiler heating elements heat, but the range burners still work, the clock may be set for a timed or self-cleaning cycle. Check to be sure the clock buttons and knobs are set properly. If your clock has a knob that says "push for man(ual)", push the knob in and try the baking and broiling elements again. If it still does not operate properly, you probably have a defect in the thermostat, selector switch, or common wiring.
If the oven does not have a separate bake/broil/etc. selector switch, the problem may be with the thermostat. But it's not easy to check the selector switch or thermostat for proper operation. If you suspect a problem in this area, call a qualified appliance repair technician.
The clock stopped
The non-electronic clocks on electric range/ovens often don't last long. That's a problem, because the clock is essential to the self-cleaning and timed-bake features. Clocks are rarely repairable--you usually just have to replace them.
Electronic clocks have been more reliable. But, they're often integrated with several other features of the range/oven. So when the clock develops a defect, it often renders the entire oven and broiler inoperative. The electronic clock is usually integrated with a circuit board, and the touchpad that holds the buttons you press is often a separate component. If your electronic clock is defective, you may need to replace the touchpad, circuit board, or both. Although these may be expensive, they aren't usually very complicated to replace.
The temperature is wrong
See the "It bakes poorly" section.
The oven light doesn't work
The interior oven light in most ovens is a standard 40 watt appliance bulb. Often, to change the bulb, you first need to remove a shield or glass dome. If the bulb isn't burned out, the problem may be with the switch on the oven door frame. If the switch works poorly, intermittently, or not at all, you need to replace it.
There's a self-cleaning problem
The self-cleaning system on an electric oven is fairly complex. To be able to set and use the self-cleaning feature, you need to read and understand the owner's manual. If you have problems with this system, call a qualified appliance repair technician.
The oven door won't close
If your oven door has gotten bent or warped (maybe you rested something heavy on it…), you need to remove the door, disassemble it, and straighten it. You can lift most oven doors off of their hinges by opening the door several inches to its first "stop," and lifting the entire door straight up.
If the hinges have become worn, damaged, or bent, you probably need to replace them. We recommend replacing both hinges at the same time, to prevent uneven wear of the undamaged hinge.
An indicator light doesn't work correctly
When an indicator light has stopped working, you may be able to replace just the bulb--but you usually have to replace the entire light assembly. Alternatively, there could be a problem with your burner sensor (stuck open or closed) or your indicator light circuit.
The oven is hot on the outside
It may be normal for your oven to become quite warm on the outside during baking, broiling, or self-cleaning. In some cases, the front door of an oven can become too hot to comfortably touch. Or, if the integrity of the door seal is poor, heat could escape from the oven and cause the overheating. Consult a qualified appliance repair technician.
Note… If you suspect that any part of the oven is dangerously hot, turn the oven off immediately and consult a qualified appliance repair technician.
I see sparks!
If you ever see sparks coming from the range or oven, unplug it immediately. Then, when the unit has cooled down, try to find exactly where the sparks came from.
If the sparks came from an obvious place like the surface burner heating elements or the bake/broil element, repair or replace any defective component you find. If you can't locate the place the sparks came from--or can't fix the problem yourself--contact a qualified appliance repair technician.
The drip pans need replacing
On most electric ranges, you can lift up the heating elements several inches and/or remove them, then remove and replace the drip bowl.
 
Gas Oven
It's stopped completely
Not all gas ranges/ovens require electricity. If yours has a clock, electronic igniters, self-cleaning, or any other electrical features, the unit needs electricity to work properly. Check to see whether there's power getting to the range/oven. Does anything turn on--even a light? If not, check for a blown fuse or tripped circuit breaker.
It won't bake
If your oven won't bake, check these:
Bake igniter
Other causes
Bake igniter
Usually when an oven won't bake, it's because the bake igniter is weak or burned out. The igniter is a small, round or rectangular device, that's about 1 inch by 4 to 8 inches. It's near the burner itself.
The burner is the tube-type device the gas flows through before it's ignited. It has many small holes on the sides to let the gas, when ignited, form a long, low flame. If the igniter is weak, if it glows red but doesn't get hot enough, or if it's burned out, the gas doesn't flow to the burner and the burner won't ignite. If this is the problem, you may need to replace either the igniter or the gas safety valve. Usually the igniter is to blame.
Other causes
Other reasons that your oven may not bake are:
The clock settings are incorrect (if you have timed baking or a self-cleaning oven).
The thermostat is defective.
The safety valve that prevents accidental gas flow is defective.
The selector switch is defective.
It bakes poorly
Here are two instances of when food "bakes poorly:"
When the item takes far too long to finish, you probably have a weak bake igniter. Often, you need to replace the igniter, but you may want to troubleshoot the oven's electrical system further to more precisely locate the defect.
When the temperature is consistent but too high or too low, the oven thermostat or sensor is either mis-calibrated or defective. If your oven uses an electronic temperature-regulating device, you may have an electric sensor in the oven instead of a mechanical thermostat. If the oven temperature is off by 30 to 40 degrees in this type of unit, you must replace the sensor.
 
On many units with a mechanical thermostat, you can remove the thermostat knob and adjust the knob itself to more accurately represent the actual setting of the thermostat. If, when you remove the knob, there's a screw on the back of it with a small calibration plate, you can loosen the screw, adjust the plate, then tighten the screw again. If the knob isn't adjustable, and the oven temperature is off by more than 30 to 40 degrees, you need to replace the thermostat to solve the problem.
It won't broil
If your oven won't broil, check these:
Broil igniter
Other causes
Broil igniter
Usually, when an oven won't broil, it's because the broil igniter is weak or burned out. The igniter is a small, round or rectangular device, about 1 inch by 4 to 8 inches. It's near the burner itself.
The burner is the tube-type device the gas flows through before it's ignited. It has many small holes on the sides to let the gas, when ignited, form a long, low flame. If the igniter is weak, if it glows red but doesn't get hot enough, or if it's burned out, the gas doesn't flow to the burner and the burner won't ignite. If this is the problem, you may need to replace the igniter or the safety valve. Usually the igniter is to blame.
Other causes
Other reasons that your oven may not broil are:
The clock settings are incorrect (if you have timed baking or a self-cleaning oven).
The thermostat is defective.
The safety valve that prevents accidental gas flow is defective.
The selector switch is defective.
A burner doesn't work
The most common problem for gas surface burners is that they get gas but don't light. This is generally caused by dirt or grease splatters on the burner itself. Residential-grade range/stove burners are round and have small holes around their perimeter to allow gas to flow out and create a round flame. The gas coming from these holes is often ignited by a small vertical row of holes on the side of the burner. If these vertical holes are clogged or obstructed, the gas can't ignite.
The solution is to clean the burners thoroughly. Use a toothpick to clear the small vertical holes, then allow the burner to dry completely and try lighting it again. If it doesn't light immediately, either repeat the procedure or call a qualified appliance repair technician.
It won't bake or broil
If neither the oven nor the broiler heats, but the range burners still work, the clock may be set for a timed or self-cleaning cycle. Check to be sure the clock buttons and knobs are set properly. If your clock has a knob that says "push for man(ual)," push the knob in and try heating the oven and broiler again. If they still don't work properly, you probably have a defect in the thermostat, selector switch, or common wiring.
Note… If the oven doesn't have a separate bake/broil/etc. selector switch, the problem is often with the thermostat. It's not easy to check the selector switch or thermostat for proper operation. If you suspect a problem with either of these, call a qualified appliance repair technician.
