Range Common Parts Glossary

Bake element

The bake element is at the bottom of an electric oven and provides heat for baking.

Broiler element

The broiler element is at the top of an electric oven interior and provides the heat for the broiling.

Ceramic glass cooktop

The ceramic glass cooktop for an electric range provides a flat, smooth cooking surface. The radiant elements attached under the cooktop provide heat.

Coil surface element

The coil surface element, also known as the coil element, plugs into the terminal block in an electric cooktop. It's controlled by a surface element switch (also called a surface burner switch or infinite burner switch) and sits above a drip pan. It heats that location on the cooktop.

Control panel

The control panel houses the control keypad, temperature display and other displays. Switches and the electronic control board are attached to the control panel.

Door light switch

The oven door light switch is a plunger switch on the frame of the oven above the opening to the oven. The oven door pushes the oven light switch plunger in when the door is closed to turn the light off. When the door is open, the plunger is released and the light is on.

Electronic oven control board

The electronic oven control (EOC) board governs the timing and execution of oven functions in the range. It's usually attached to the control panel and often has a digital display clock mounted on the front of its housing.

Limiter

The limiter is a limit switch on a radiant element that shuts off the element to protect the ceramic glass cooktop from overheating. One some models, the limiter can be replaced as a separate component, but on some others it's incorporated into the element. If a surface element fails to heat, or the limiter isn't regulating the maximum temperature properly, replace the limiter.

Outer oven door glass panel

The outer oven door glass panel is the heat-resistant piece of glass that forms the outer part of the oven door.

Oven control thermostat

The oven thermostat is mounted in the control panel of the oven and has a control dial for setting the desired oven temperature. The oven control thermostat turns the heat on and off to maintain the set temperature. The control thermostat connects to a sensor tube; that sensor tube then connects to a sensor bulb that detects the actual temperature inside the oven.

Oven door hinge

The hinges on an oven door control the rate at which the door opens and also allow the door to stay open at an angle. Hinges are usually installed in pairs so the hinges and tension springs match, ensuring the smooth operation of the door.

Oven door hinge kit

The hinges on an oven door control the rate at which the door opens and also allow the door to stay open at an angle. Hinges are usually installed in pairs so the hinges and tension springs match, ensuring the smooth operation of the door. The oven door hinge kit usually has 2 hinges, one for each side of the oven door. It has related parts such as receivers for the hinges that mount in the frame of the range.

Oven door lock assembly

The oven door lock assembly is a safety mechanism that prevents accidental burns and oven fires by latching the door shut during self-cleaning. The door unlocks when the oven cools to a safe temperature (usually less than 200 degrees F). It's also used on ovens with the child lock-out feature. The assembly includes the lock and switches that detect whether the door is locked.

Oven igniter

In a gas oven, the oven igniter is a glow bar that glows white hot to ignite the gas for the oven burner. It's in a series electrical circuit with the safety gas valve. The safety gas valve opens when it detects that the igniter is hot enough to light the gas. Some gas ovens have a separate bake igniter and broiler igniter, instead if a single oven igniter for both the bake burner and broiler burner.

Oven temperature sensor probe

The oven temperature sensor probe is at the top of the back of the oven and detects the temperature inside the oven. Temperature is measured by the change in resistance in this sensor, which is why the sensor is also referred to as an Resistance Temperature Detector (RTD). A wire harness connects the oven temperature sensor probe to the electronic control board so the sensor can communicate the oven temperature to the control board.

Radiant surface element

The radiant surface element is mounted on the bottom of a ceramic glass cooktop and provides heat for that area of the cooktop. It's controlled by a surface element switch (also called a surface burner switch or infinite burner switch). The radiant surface element has a limit switch that shuts off the element to protect the ceramic glass cooktop from overheating.

Range 6-foot power cord

The electrical range cord is 6 feet long and has a plug on one end that inserts into the electrical outlet for the range. The other end has either 3 or 4 wires that attach to the connection terminals on the terminal block at the back of the range.

Relay control board

Some ranges have a relay control board that's separate from the timer and control board. The relay board has electrical relays (switches) that control voltage going to major loads such as the bake element or a surface element, based on signals from the control board.

Solid surface disc element

A solid surface element (also called a solid disc element) is a solid metal surface element that's mounted on the top an electric cooktop or range for surface cooking. The cookware sits directly on the solid metal disc element. Ribbon heating coils under the solid metal disc transmit heat to the surface of the disc and then to the cookware. Solid disc elements are uncommon in the United States.

Spark igniter electrode

The spark igniter electrode provides an ignition spark to light a surface gas burner. It's an insulated electrode that sends a spark to the burner head when the spark module provides voltage. It sparks with a ticking sound when you turn the burner switch on a control knob to the Lite position.

Spark igniter switch

The spark igniter switch, or surface burner igniter, provides an ignition spark to light a surface gas burner. It's an insulated electrode that sends a spark across to the burner head when voltage is supplied by the spark module. The igniter sparks or "ticks" when the control knob is turned to the "Lite" position.

Spark module

The spark module receives signals from the burner switches. When a burner control knob is in the Lite position, the spark module provides voltage to the burner igniter electrodes and lights the surface gas burner.

Surface element receptacle

The surface element receptacle is the heavy-duty wire receptacle for the outlet cord connection. It's positioned under the cooktop at an opening of a coil surface element. The connection prongs of the coil surface element plug into the surface element receptacle to provide electrical power to that coil surface element. The wires that are connected to the receptacle go to the burner switch which turns the coil surface element on/off and controls the heat level.

Surface element switch

The surface element switch (also called a surface burner switch or infinite burner switch) is mounted on the control panel of an electric range or cooktop. It's an electrical switch that turns on and off the associated surface element and also controls the how much heat the element produces.

Terminal block

The terminal block is an electrical connection component. Located on the back of the range near the electric power cord, the terminal block has connection points for the wires of the electrical power cord and is the connection point for incoming electrical power. It is the wire receptacle on the back of the range.

Thermal fuse

Many ovens have a bi-metal thermal fuse—also called a thermal limit switch—that protects the oven from overheating. The oven thermal fuse trips when the controls aren't working properly and the temperature in the oven gets too hot.
