Oven, range and cooktop problems and their usual causes
An electric oven heats with a bake element at the bottom and a broil element at the top, and a temperature sensor tells the control when to cycle them. The cooktop burners each have their own switch or control. When one part of the range quits while the rest works, that narrows the cause quickly.
| What you notice | What it usually points to |
|---|---|
| Oven won't heat, but the cooktop works | Burned-out bake element (often with a visible break or blister), failed temperature sensor, control board relay, or a thermal fuse |
| Broil works, bake doesn't (or the reverse) | The element that isn't heating, or the relay on the control board that powers it |
| Nothing heats, but the display and lights work | One side of the range's double breaker tripped, or a problem at the power cord or terminal block |
| Runs hot, runs cold or bakes unevenly | Temperature sensor drift, a weak element, a worn door gasket, or the convection fan not running |
| One coil burner won't heat | The burner itself, a burned socket (receptacle), or the burner's infinite switch |
| Burner stuck on high, won't turn off | A failed infinite switch, or a stuck relay on glass-top and touch-control models |
| Glass-top burner won't heat, or the hot-surface light stays on | Radiant element, its switch or limiter, or the hot-surface indicator circuit |
| Self-clean door stays locked | Oven still cooling, or a failed door lock motor or lock switch |
| Display blank or showing an error code | Power interruption, a failed control board or touchpad, or a sensor fault the board is reporting |
Over-the-range microwaves fail in their own ways. If yours is above the cooktop, the microwave repair page covers it.
Quick checks for an electric oven or range
- Breaker. Electric ranges run on a double breaker. Turn it fully off, then back on. A half-tripped breaker can leave the display lit and nothing heating.
- Control lock and timers. A control lock, Sabbath mode or a delayed-start timer can keep the oven from heating. Check the manual.
- Look at the bake element. With the oven off and cool, a visible break, bulge or blister on the lower element means it's done.
- Swap coil burners. With the range off and cool, move the dead burner to a working socket of the same size. If it heats there, the socket or switch is the problem.
- Use an oven thermometer. If baking seems off, measure the real temperature on the middle rack after the oven has been at temperature for 20 minutes.
What an oven or range repair involves
- Supply check. The technician confirms the range is getting full 240-volt power and looks at the power cord and terminal block for heat damage.
- Testing. Bake and broil elements, the temperature sensor, infinite switches, the door lock and the control board's outputs are tested with a meter.
- Wiring inspection. Ovens and cooktops get hot, and wire terminals at elements and burner sockets can burn over time. Damaged terminals get replaced along with the part.
- Repair. Most element and sensor repairs are done from inside the oven or the back panel. Wall ovens are slid partway out of the cabinet. Glass cooktops are lifted to reach the elements and controls.
- Heat test. The oven is brought up to temperature and the burners cycled before the job is done.
What sets the price of an oven or range repair
Elements, sensors and coil burner parts are the common, moderate repairs. Control boards, touchpads and glass tops cost more.
- The part. A bake element or sensor is a simple part to replace. Electronic control boards and touch panels cost more and are often model-specific.
- Glass cooktop replacement. The glass top is one of the more expensive range parts. On an older range, it can tip the decision toward replacing.
- Wall ovens and double ovens. Built-in wall ovens are heavy and have to be slid out of the cabinet, which adds time.
- Heat damage. Burned wiring, terminals or burner sockets add parts.
- Self-clean lock failures. A lock stuck closed has to be released before the oven can be repaired.
If a big repair lands on an older range, our guide to repairing versus replacing lays out how to compare the two.
Range problems that need immediate attention
Most oven trouble means a few days of cooking around it. These do not. Switch off the range breaker and call:
- A burner or element that stays on and won't turn off.
- An oven element that sparks, flashes or burns through.
- Smoke that isn't from food, or a smell of hot plastic or wiring.
- A cracked glass cooktop. Don't use it, even on the burners away from the crack.
- The breaker trips whenever the oven or a burner turns on.

Electronic range controls and Bradenton power outages
FPL, the electric utility serving most of Bradenton, tells customers to turn off and disconnect electronic equipment during an outage, and to turn appliances back on one at a time when power is restored. Most ranges sold today have electronic controls, so that advice applies to the range too.
A range is hard to unplug: the cord is behind a heavy appliance, and wall ovens and cooktops are usually hardwired. The practical way to follow FPL's advice is to switch off the range's double breaker when the power goes out, and switch it back on once power has been steady for a while.
If the range acts up after the power comes back
- Clock flashing or the time reset: normal after any outage. Set the clock; some ranges won't start a bake until you do.
- An error code, or touch buttons that don't respond: turn the range breaker off for about a minute, then back on. That resets the control on most models.
- Display works but nothing heats: check that both sides of the double breaker reset fully.
- Still dead, still showing a code, or one element never heats: a relay or component on the control board may have been damaged. That's a repair call.
For the rest of the house, see our guide to appliances after a power outage.
Before the technician gets there
- Let the oven cool completely, and take the racks out.
- Clear the cooktop and the counter next to the range.
- Write down any error code and what the oven does before it stops.
- Find the model number, usually on the frame behind the storage drawer or the oven door, or under the cooktop on some models.
After the repair
Bake something familiar and check the result, or confirm with an oven thermometer. Don't line the oven floor with aluminum foil; most manufacturers warn against it because it traps heat and can damage the oven's enamel and hidden elements.
Keep coil burner drip pans clean so spills don't reach the sockets, and use cooktop cleaner on glass tops. Grit dragged across the glass scratches it.
Oven and range questions
Why does my oven bake unevenly or run hotter than the setting?
Put an oven thermometer on the middle rack and compare it to the setting after 20 minutes. Some swing is normal because ovens cycle on and off.
A steady difference usually points to a temperature sensor that has drifted, a weak bake element or a worn door gasket. Many ovens also have a temperature offset setting in the manual for small corrections.
Is it safe to use a cracked glass cooktop?
No. Stop using it and switch off the range breaker. Spills can reach the elements and wiring through a crack, and the glass can break further when it heats. The glass top can be replaced on most ranges and cooktops.
Why won't one coil burner heat?
With the range off and cool, swap the dead burner with a working one of the same size. If the dead burner works in the other socket, the problem is the socket or the switch for that position.
If it stays dead, the burner itself is bad. A socket with burned or melted contacts should be replaced along with the burner.
Do you repair gas ranges and ovens?
No. We work on electric ovens, ranges and cooktops only. Gas appliances need a company that services gas.
Should I use the self-clean cycle?
It's there to be used, but the cycle runs the oven far hotter than normal cooking, and that heat is when weak parts like sensors, fuses and door locks tend to fail. Avoid running it right before a holiday or a day you need the oven, and wipe out heavy spills first.
