318255006 Frigidaire Oven Range Bake Element is an electric resistive heating component designed for use in Frigidaire electric ovens and ranges; it is the replaceable tubular heating element mounted at the bottom of the oven cavity that converts electrical energy into the heat used for baking. Constructed as a sealed metal sheath containing a resistance alloy, the element terminates in insulated electrical connectors and is secured to the oven floor or support brackets to deliver radiant and convective heat to the cooking chamber.
Within the appliance system the bake element is a primary heat source and works in concert with the oven control board or mechanical thermostat, temperature sensor or probe, relays or triacsand the wiring harness. When energized by the control system it dissipates power as heat, and its thermal output and cycling determine oven temperature stability; faults in the element (open circuit, short to ground, hot spots) or its connections can affect temperature regulation, safety interlocksand component load on the control circuitry.
In this article readers will find a technical overview of the element’s function and typical electrical/physical characteristics, guidance on model compatibility and part-number considerations, common failure symptoms to recognise (such as no heat, uneven heating, visible damageor electrical arcing)and practical troubleshooting checks a technician or appliance owner can perform (visual inspection, continuity/resistance measurementsand wiring/connection verification). The article also covers replacement considerations including matching terminal types and ratings, proper mounting and sealingand essential safety precautions such as disconnecting mains power before inspection or service.

function and Role of the Bake Element in Heat Generation and Oven Temperature Regulation
the 318255006 Frigidaire Oven Range Bake Element is a tubular resistive heater that converts electrical energy into the primary radiant and convective heat used during bake cycles. Installed at the bottom of the oven cavity, the element heats by the Joule effect when supplied with the oven’s rated voltage; its steady, predictable resistance determines power output and thermal response. For compatibility, technicians should match the part number to the oven model, verify terminal type and mounting clips, and confirm the element’s electrical rating before replacement to ensure proper fit and safe operation.
- Function: generates steady radiant and convective heat in bake mode.
- Control behavior: cycles on and off under thermostat or electronic control to maintain set temperature.
- Compatibility checks: connector style, mounting bracketsand voltage rating must match the oven.
- Failure indicators: open circuit on an ohmmeter, prolonged preheator uneven baking across racks.
The bake element works in concert with the oven thermostat, temperature sensor (thermistor or thermocouple), and electronic control board to regulate cavity temperature. When the controller calls for heat the element energizes; as the cavity approaches setpoint the controller reduces duty cycle by switching power to the element on and off. in practical troubleshooting,measuring the element resistance and observing cycling behavior at the control (or using a clamp meter to observe current draw during a bake cycle) helps distinguish a failed element from control or sensor faults. Replacing a degraded element typically restores proper heat output and uniformity, while mismatch in rating or mounting can cause poor performance or connector failure.

How the 318255006 Frigidaire Oven Range Bake Element Integrates with Control Systems, Wiringand Thermal Sensors
The 318255006 Frigidaire Oven Range Bake Element is a resistive heating component that integrates directly with the oven’s control system by being switched on and off by relays, triacsor contactors on the control board.When the control applies mains voltage across the element terminals, the element converts electrical power into heat; the control system modulates that power (on/off cycling or phase control) to achieve the commanded temperature. Compatibility concerns during replacement include matching the element’s terminal spacing and mounting brackets, verifying the nominal voltage rating (typically 240 V for North American ovens)and confirming the element’s DC resistance matches the specification so control timing and thermal response remain consistent with factory calibration.
Thermal sensors - commonly an NTC thermistor or a simple mechanical thermostat/limit switch – provide the control board with real-time temperature feedback; the board uses that feedback for duty-cycle calculations or PID/hysteresis control to maintain setpoint. Wiring practice separates high-voltage element conductors from low-voltage sensor leads and uses secure spade connectors or crimp terminals to avoid intermittent contact; shielded or routed sensor wiring reduces noise that could cause erroneous temperature readings. Practical diagnostics include verifying the element’s continuity and expected resistance range, checking for shorts to chassis groundand measuring the sensor resistance at room temperature to confirm it matches the expected value for that sensor type; an open element or a sensor out of range will prevent the control from correctly energizing the element or will cause improper cycling.
- Typical diagnostic steps: verify mains supply to element, measure element resistance, check for ground shorts, measure sensor resistance, inspect spade connectors and wire routing.
- Control interactions: relays/triacs switch mains to the element; sensors provide low-voltage feedback to the control board for temperature regulation.
- Common failure modes: open element, short to ground, intermittent connectoror sensor drift/failure causing incorrect regulation.

Common Failure Symptoms and Diagnostic Indicators of a Faulty Bake Element
the 318255006 Frigidaire Oven Range Bake Element is the primary resistive heater used for bake cycles; it converts electrical energy into radiant and convective heat distributed across the oven cavity. As a tubular heating element, its expected behavior is steady resistive heating when the control relay or infinite switch supplies 240 V; variations in mounting, terminal spacing, and sheath length determine compatibility with specific Frigidaire range models. Functionally the element is a simple resistive loop, so mechanical damage to the sheath, terminal corrosion, or insulation breakdown will alter its electrical characteristics and heat output without changing the oven control logic.
- No heat or considerably reduced heat during bake cycles while other circuits (for example, broil) still operate.
- Uneven cooking or hot spots caused by partial open circuits within the element.
- Visible deformity, blistering, breaks in the sheath, or evidence of arcing at terminals.
- Circuit breaker trips or oven control faults that coincide with element energization, indicating shorts to ground or intermittent contact.
| Item | Description |
|---|---|
| Typical cold resistance | Approximately 20-40 Ω for common 240 V bake elements (varies with wattage). |
| Failure electrical signatures | Open circuit (OL/infinite) = open element; low resistance to chassis = insulation short to ground. |
Diagnosing the element starts with a visual inspection and progresses to electrical checks after power is disconnected at the breaker. A continuity or resistance check across the two element terminals should read in the low tens of ohms; an open reading indicates a broken heater, while a measurable low-resistance path between either terminal and the oven chassis indicates insulation failure and risk of arcing. For in-circuit ambiguity, remove the element from its mounting and retest to isolate wiring or control board faults; technicians commonly confirm a defective element if removal yields an OL reading or shows visible sheath damage when inspected under good lighting.
Replacement Considerations, Step-by-Step Installation Procedureand Safety Checks for the Bake Element
The 318255006 Frigidaire Oven Range Bake Element is a resistive heating element that provides the primary radiant heat for the oven bake cycle.It converts electrical energy into heat thru a metallic resistance conductor encapsulated in an inert sheath; normal behavior includes dull-red thermal emission during active heating and repeatable temperature response under control of the thermostat/controls.Common failure modes are open-circuit (no heat), partial shorts to chassis (tripped breakers or blown fuses), and mechanical damage such as kinking or sheath breaches that cause uneven heat distribution. Verify compatibility by matching the element’s physical mounting flange, terminal type (fast-disconnect or screw), voltage ratingand overall length to the oven model; replacement elements are not universally interchangeable even within the same manufacturer family because of these mechanical and electrical differences.
Replacement requires simple mechanical access but strict electrical safety and basic verification with a multimeter. Before reassembly, perform the procedural checks below: the element must be mechanically secured with the correct fasteners, electrical connectors must be tight and insulated, and the oven should be energized only after confirming continuity and absence of short-to-ground. After powering up, validate operation at a low bake temperature and confirm even heat across the oven cavity; if temperatures remain low or breakers trip, re-isolate power and re-check wiring and insulation. For technicians,document the original terminal positions (photograph if necessary) and note that acceptable cold resistance for most 240 V bake elements typically falls in the low tens of ohms - a significantly higher or infinite reading indicates an open element.
- Disconnect power at the breaker and verify with a voltmeter before touching terminals.
- Remove racks and access back/interior panel to reach mounting screws and terminals.
- Photograph terminal connections, then disconnect and remove the old element; inspect for sheath damage or carbonization.
- Install new element, secure mounting screws, reconnect terminals in original orientation, and ensure strain relief and insulation are intact.
- Measure continuity and check for short-to-ground before restoring power; perform a low-temperature test bake and inspect for even heating and abnormal smells or smoke.

Q&A
What is part 318255006 and which ovens does it fit?
Part 318255006 is the OEM bake (lower) heating element used in many Frigidaire-built electric ranges and wall ovens.It is commonly used across various Frigidaire, Electrolux and Kenmore models built by Frigidaire. compatibility varies by model and production year, so always verify fit by checking your appliance model number (usually on a tag inside the oven door frame or on the rear panel) and cross-referencing with the manufacturer’s parts list or a trusted parts supplier.
What are the common symptoms that the bake element is failing?
Common signs of a bad bake element include: the oven not heating to set temperature or heating very slowly; uneven baking or hot spots; visible damage such as blisters,breaks,or white/gray powdery insulation; a burning or electrical smell when the oven is on; or the circuit breaker tripping when the oven is used. Note that some symptoms (like uneven heating) can also be caused by a faulty thermostat/temperature sensor or control board, so test the element before replacing other components.
How do I test the bake element to see if it’s faulty?
Always disconnect power at the breaker before testing. Remove the element access (usually by unscrewing mounting screws and pulling the element slightly out to expose the spade connectors). Use a multimeter set to the ohms (Ω) scale: measure continuity across the two element terminals - a working 240V oven element typically reads roughly 10-40 Ω depending on wattage (you can calculate expected resistance using R = V² / P if you know the element wattage). Also check for leakage to ground by measuring between each terminal and the metal chassis; you should see infinite (open circuit). Any open circuit across the two terminals or continuity to chassis indicates a bad/shorted element.
Can I replace the 318255006 bake element myselfand what safety steps should I follow?
Yes, many owners can replace the bake element themselves if they are cozy with basic hand tools. Safety steps: turn off power to the oven at the breaker (do not rely on the oven’s controls), confirm power is off with a non-contact tester if available, remove oven racksand let the oven cool fully. Unscrew the element mounting screws (ofen at the rear of the oven cavity), pull the element forward slightly to access the spade connectors, disconnect the wires (note orientation or take a photo), install the new element by reversing the stepsand restore power to test.If you’re not comfortable working with household wiring, hire a qualified technician.
What resistance value should I expect when measuring the 318255006 element?
Resistance depends on the element’s wattage. For a 240 V element, use R = V² / P. Example: a 2500 W element gives about 23 Ω (240² / 2500 ≈ 23 Ω). A 3000 W element is around 19 Ω. Many common bake elements fall in roughly the 10-40 Ω range. The crucial checks are that there is continuity across the two terminals (not open) and no continuity to the metal chassis (no short to ground). if reading is open or there’s continuity to chassis, the element is defective.
How long does a replacement take and what tools/parts do I need?
Typical replacement takes 15-45 minutes for someone prepared with basic tools. You’ll need: the correct replacement element (318255006 or verified equivalent),a screwdriver or nut driver to remove mounting screws,needle-nose pliers to remove spade connectors if needed,and optionally a multimeter to test. Have gloves and eye protection. If connectors are corroded or nailed down, additional tools or replacement connector terminals may be required.
What differences are there between a bake element and a broil element?
The bake element (part 318255006) is mounted at the bottom of the oven cavity and is used for sustained, lower-position heating during baking. The broil element is located at the top of the cavity and is designed for short, high-temperature surface heating. they differ in shape, length, wattage and mounting style; they are not interchangeable unless explicitly specified. When ordering,be sure you are replacing the bake element specifically.
My oven still won’t heat after replacing the element – what else should I check?
If a new element does not restore heating, check: 1) the household circuit breaker and wiring (ensure the oven is receiving both hot legs on a 240 V circuit), 2) the oven temperature sensor (measure its resistance; typical thermistors are ~1,000 Ω at 72°F but check your model specification), 3) the oven control board/relay and electronic controls, 4) high-limit thermostats or thermal fuses (some models have safety cutouts), and 5) proper wiring connections to the element. If you’re unsure or suspect control board or electrical supply issues, call a qualified technician to diagnose and repair safely.
