How Does an Electric Range Work?

What Is an Electric Range?

An electric range is a type of kitchen appliance that combines both an electric stove and oven, allowing you to cook on the stovetop and bake or roast within the oven compartment. These ranges are popular for their ease of use, steady heat control, and fewer safety risks compared to gas appliances.

Core Components of an Electric Range

To understand how an electric range works, let’s first look at its key components:

• Heating Elements: Electric ranges have two types of heating elements—one for the stovetop and one for the oven. Heating elements work by sending a stream of electrical current through a high-resistance wire that heats up as electrons collide with current-resistant metal.
• Stovetop Burners: Coils elements or radiant surface elements for a ceramic glass top ranges heat up to provide direct heat for pots and pans.
• Oven Heating Elements: Usually located at the top and bottom of the oven, these elements create the temperature needed for baking and roasting.
• Surface Burner Control Switches: Also known as burner infinite switches, these components control the heat level of stovetop burners.
• Electronic Oven Control Board: This circuit board governs oven operations including the bake mode, broil mode and self-cleaning mode.
• Oven Temperature Sensor: This device senses oven temperature and sends that signal to the electronic oven control board to accurately control oven temperature.
• Control Panel: Houses oven and stovetop controls that allow you to adjust the oven temperature, timer, and control surface elements.
• Electrical Wiring: Powers the heating elements and controls, allowing electricity to flow through the appliance safely.

How Electric Stovetop Burners Work

When you turn on an electric stovetop burner, a few steps occur to generate heat:

Step 1: Turning burner control knob on the control panel allows electricity to flow to the coil or ceramic element.
Step 2: The heating element’s resistance to the electricity causes it to heat up. This principle, known as Joule heating, is the same process that warms up an electric space heater.
Step 3: The stovetop burner will continue to heat up until it reaches the desired temperature, and then the control switch maintains that temperature by cycling the element on and off.

How the Electric Oven Works

The electric oven functions in much the same way as the stovetop but involves more complex temperature control to ensure consistent cooking.

Step 1: When you set the oven to a specific temperature, electricity flows to the oven’s heating elements (usually at the top and bottom).
Step 2: These elements warm up and distribute heat evenly across the oven interior.
Step 3: The oven’s temperature constantly monitors the oven cavity temperature, cycling the heating elements on and off to keep it consistent.

Oven Heating Options:

• Bake Setting: Activates the bottom heating element, making it ideal for baking.
• Broil Setting: Activates the top heating element, providing direct heat from above for browning and finishing dishes.
• Convection Option (if available): A fan circulates hot air, offering more uniform cooking and quicker results.

Advantages of Electric Ranges

Electric ranges have several benefits:

• Steady, Even Heat: Electric burners heat consistently, allowing for precise cooking.
• Ease of Installation: Most homes are equipped with electrical outlets, while gas lines are less common.
• Low Maintenance: Electric ranges have fewer parts and are easier to clean, especially with smooth-top surfaces.
• Safety: No open flame reduces fire risks and eliminates the need for ventilation.
• Rebates: Using an electric range helps the environment when compared to a gas range, so you can soon get up to an $840 rebate for switching from a gas to electric range under the HEEHRA electrification provisions of the 2022 Inflation Reduction Act passed by the U.S. Congress.

Maintenance Tips for Electric Ranges

To keep your electric range working efficiently and safely, consider these maintenance tips:

• Clean Regularly: Wipe down the stovetop after each use, and regularly clean oven spills to prevent buildup.
• Inspect Heating Elements: Check for visible damage, like cracks or worn-out coils, and replace if necessary.
• Use Correct Cookware: Ensure the cookware is flat-bottomed and appropriate for electric burners.
• Professional Maintenance: Schedule annual range maintenance to have a professional inspect the wiring, controls and components to ensure the stove stays in good condition. Immediately schedule range repair if you notice any issues or failures.

Troubleshooting Common Electric Range Issues

If your electric range isn’t functioning correctly, these DIY troubleshooting tips might help.

Oven Won’t Heat

An inadequate power supply, wiring failure, bad bake element, defective temperature sensor or failed electronic control board all could all prevent an electric oven from heating. Watch this video from Sears PartsDirect to see how to troubleshoot the problem.

If you’re unable to find and fix the oven heating problem yourself, schedule range repair service to have a Sears Home Services technician resolve the issue.

Surface Element Won’t Heat

A failed element, wiring failure or a broken surface element control switch could be the reason that a stovetop element is not working. Follow the DIY troubleshooting steps in this video to resolve the problem on your own.

If you’re unable to fix the surface element heating problem on your own, schedule repair service and we’ll send a technician to your home to fix the issue for you.

Range Won’t Power Up

When your range doesn't work at all, it's likely that the range has no electrical power for the display or controls. Possible causes are a tripped house circuit breaker for the range, a problem with the outlet cord (not plugged in or broken) or an internal wiring failure.

Check the house circuit breaker for your range and reset the breaker if you find it tripped.

Unplug the range and check the terminal block on the back of the range for loose wires or broken terminals. Replace the terminal block if damaged.

A blown thermal fuse can prevent the control from powering up on some ranges. Some ranges have a relay control board that supplies power to the display and controls so a failed relay control board could prevent the range from working.

If you’re unable to find the cause of the power problem, schedule range repair service and we’ll send a tech to your home to fix the range for you.

Understanding the workings of an electric range can help you make the most of this appliance and ensure it operates safely and efficiently for years to come. By knowing how each part functions—from the stovetop burners to the oven’s heating elements—you’re better equipped to troubleshoot issues, maintain the appliance, and make delicious meals with confidence.
