318254902 Frigidaire Oven Element is an electric tubular heating element designed for use in Frigidaire electric ovens and ranges; as a replacement part it is the resistive element that generates the primary heat used for baking or broiling. Physically, the component typically consists of a metal sheath surrounding a resistive wire (commonly a nickel-chromium alloy) and is formed to fit the oven cavity, with terminal lugs for electrical connection and mounting brackets for secure attachment.
Within the appliance, the element converts incoming electrical energy into thermal energy and is directly responsible for raising and maintaining oven temperature. It interfaces electrically with the oven control board, internal relays or switches, and the temperature-sensing system (thermostat or thermistor), and mechanically with the oven cavity and mounting hardware. Its condition and electrical characteristics (resistance, continuity, and insulation to chassis) affect temperature uniformity, cycle times, and interaction with control algorithms and safety devices such as thermal cutouts or fuses.
This article will cover the element’s functional principles and typical electrical and mechanical specifications, how to determine compatibility with specific Frigidaire models, common failure symptoms (open circuit, short to ground, hot spots, and uneven heating), practical troubleshooting checks a technician can perform (visual inspection, continuity and voltage checks at terminals), and considerations when sourcing and installing a replacement (matching part number, dimensions, terminal type, voltage/wattage rating, and safety precautions). The goal is to provide the technical context needed for informed diagnosis and appropriate replacement decisions without prescribing detailed procedural steps.

Function and Role of the 318254902 Frigidaire Oven Element in Heat Generation and Temperature Control
The 318254902 frigidaire Oven Element is a resistive heating element designed to convert electrical energy into infrared and convective heat for bake and/or broil functions. Internally it contains a high-resistance alloy conductor enclosed in a metal sheath; when line voltage is applied the conductor produces heat along the sheath surface.In operation the element is mounted to the oven cavity and transfers heat directly to the air and cookware; proper function depends on matching the element’s wattage, physical length, terminal type, and mounting bracket to the oven model so that the element draws the expected current and distributes heat as intended.
- Role in control: provides the heat source that the oven control modulates by switching the element on and off to maintain setpoint temperature.
- Symptoms of failure: no heat in bake or broil mode, uneven cooking, visible breaks, or a short to chassis causing tripped breakers.
- Practical checks: continuity and insulation-to-ground tests with a multimeter; visual inspection for blistering, breaks, or burned insulation at terminals.
- Compatibility considerations: confirm terminal style, element length, mounting holes, and rated wattage/voltage before replacing.
The element works in concert with the oven control board or mechanical thermostat and the oven temperature sensor to regulate temperature; the controller varies the element’s duty cycle (on-time versus off-time) rather then continuously varying power, so accurate temperature control relies on predictable element resistance and heat output. For example, a failing bake element may show open circuit resistance and produce no heat while the broil element (if separate) still functions, or a partially shorted element may cause longer on-times and overshoot set temperatures. Technicians typically verify function by measuring resistance in the low tens of ohms for common 208-240 V elements, checking for continuity to ground, and confirming that replacement parts match mechanical and electrical specifications to preserve oven temperature behavior.

How the 318254902 Frigidaire Oven Element Works Inside the Appliance: Electrical Characteristics and Thermal Behavior
the 318254902 frigidaire Oven Element is a resistive heating component engineered to convert mains electrical power into radiant and convective heat inside the oven cavity. Electrically it behaves as a low‑ohm resistor designed for typical household range voltages (generally 208-240 V) and a rated wattage chosen to meet the oven’s heat-up and recovery specifications; expected cold resistance values for similar elements usually fall in the range of roughly 15-35 Ω, with power determined by P = V²/R. The element is formed from a nickel‑chrome alloy conductor encapsulated in an inert sheath and terminated at insulated spade or stud terminals; correct terminal spacing, mounting brackets, and matching wattage are required for compatibility with the oven’s control circuitry and thermal profile. Technicians verify the element electrically with a digital multimeter (continuity and resistance) and check for insulation failure by testing for shorts to chassis ground before declaring a replacement necessary.
Thermally, the part produces a rapid rise in surface temperature when energized and then cycles with the oven thermostat or relay to maintain setpoint, so heat flux, emissivity, and the element’s thermal mass determine warm‑up time and temperature uniformity. Uneven heating, localized blistering of the sheath, or a progressive increase in measured resistance are typical indicators of internal degradation; conversely, a perfectly open circuit or a clear short to ground are definitive failure modes. Compatibility issues manifest as slow recovery times or nuisance breaker trips if a replacement has significantly different wattage or resistance; practical diagnostics include IR thermography to check for uniform surface temperature, timed warm‑up checks against known oven performance, and comparison of measured resistance to the nominal range for the replacement part.
- Operating voltage: 208-240 V (household range ovens)
- Typical wattage range: ~2,000-3,500 W depending on element role (bake vs. broil)
- Cold resistance (typical): approximately 15-35 Ω
- Common failure signatures: open circuit, short to chassis, sheath blistering, uneven heating
| Item | Description |
|---|---|
| Example operating condition | 240 V, 2,800 W → cold resistance ≈ 20.6 Ω (approximate) |
| Warm‑up time | Several minutes to reach steady radiant temperature; varies with wattage and oven size |
| Diagnostic checks | Multimeter resistance/continuity, insulation to ground, IR surface scan |
Common Failure Symptoms, Visual Indicators and Electrical Test Results for Oven Elements
The 318254902 Frigidaire Oven Element typically fails in ways that produce distinctive electrical and visual clues. Visible indicators on a failed element include breaks or pinholes in the sheath, localized blistering or white powder (oxidation), sagging or kinks, and dark burn marks around the terminal ends. Functionally, a defective element can cause no heating, partial heating with cold spots, long recovery times, uneven bake results, or intermittent operation; in some cases a short to chassis will trip circuit breakers or fuses. Technicians should also inspect terminal connections and mounting clips for corrosion or loose fittings, since poor connections can mimic element failure by increasing contact resistance and producing heat at the terminals rather than along the element length.
- No heat at all - typically indicates an open circuit inside the element or a failed internal connection.
- Uneven heating or hot spots - suggests partial breaks,internal shorting,or sheath damage allowing localized heating.
- Tripping breaker or blowing fuses – consistent with short to ground caused by insulation breakdown.
- Visible arcing, soot, or burning at terminals – points to terminal failure or poor connection rather than element resistance change.
Electrical testing confirms the symptoms: isolate power to the appliance and disconnect the element before measuring. Use a digital multimeter set to the low-ohm range to measure resistance between the two element terminals; a correctly functioning bake element will show a low resistance in the low tens of ohms (for example, a 3,000 W element on 240 V is approximately 19 Ω), whereas an infinite reading indicates an open element. Measure between each terminal and the metal sheath (or chassis); a normal result is open/very high resistance, and a low reading indicates a short to ground. Also verify wiring, terminal clips, and any thermal cutouts or sensors in series with the element, because a failed thermal fuse or poor terminal contact can produce identical symptoms even when the element resistance is within specification.
| Item | Description |
|---|---|
| Continuity between terminals | Low resistance (typically low tens of ohms) indicates a continuous heating element. |
| Open circuit | Infinite resistance between terminals; element has failed and requires replacement. |
| Short to ground | Low resistance from terminal to element sheath or chassis; insulation breach-replace element and inspect wiring. |
Replacement Considerations, Model Compatibility and step‑by‑Step Installation Procedure
The 318254902 Frigidaire Oven Element is a resistive heating component that converts line voltage into thermal energy to heat the oven cavity. Structurally it consists of a coiled resistance conductor sealed in a metal sheath with mounting tabs and insulated terminal spades; electrical failure modes include open circuit (no continuity), reduced output due to partial breakage or scaling, and insulation breakdown causing a ground fault. Technicians verify condition by measuring continuity with a multimeter and by estimating expected resistance from the nameplate wattage and supply voltage (for example,R = V²/P gives roughly 23 Ω for a 240 V,2500 W element),and by visually comparing terminal/spade geometry and mounting tab locations to ensure mechanical and electrical compatibility with the appliance model.
Replacement and installation require safe isolation of power and attention to terminal orientation and mounting geometry so the element seals and heats evenly.Disconnect the appliance at the circuit breaker, remove interior panels or rear access as required, label and photograph wire connections, unfasten mounting hardware, swap the element while preserving wire order and insulation, then verify continuity and perform a short functional test at low temperature before reassembling. Practical tips include confirming spade size fit,using heat-resistant anti-seize on metal threads if specified by the manufacturer,and checking for gasket or insulation damage that should be replaced concurrently to prevent heat loss or arcing.
- Turn off and lock out power at the breaker panel.
- Remove oven racks and access panels; document wiring orientation.
- Disconnect terminal spades and remove mounting screws/tabs.
- Install new element aligning tabs and reconnect wires to original terminals.
- Verify continuity and perform a brief heat test before full reassembly.

Q&A
What exactly is the 318254902 Frigidaire oven element and how do I know if it is indeed the right part for my oven?
The 318254902 is an oven heating element sold as a replacement part for certain Frigidaire/Frigidaire Gallery/frigidaire Professional ovens. It might potentially be listed as a bake or broil element depending on the specific oven model. To confirm fitment, locate your oven’s full model number (usually on a tag inside the oven frame, on the door frame, or behind the kickplate) and cross‑reference that model number with the part listing from Frigidaire/Electrolux or an authorized parts supplier.Also compare the physical shape, mounting bracket style and terminal type of the replacement to the old element.
What are the common symptoms that indicate the 318254902 oven element is failing?
Common symptoms include: the oven not reaching set temperatures, uneven baking or hot spots, one function (bake or broil) not heating at all, the element not glowing when it should, visible breaks, blisters or white powder on the element, and sometimes tripping a breaker or a GFCI. If only one element (top or bottom) is affected and other oven functions work, the element is a likely culprit.
How do I test the 318254902 element with a multimeter?
First disconnect power at the breaker. Remove the element so you can access its terminals and isolate it from wiring. Set a multimeter to continuity or resistance (ohms). Measure between the two element terminals: a good heating element should show low resistance (not infinite). If you get OL (open circuit) the element is failed. Also test between each terminal and the metal element housing (ground): you should see no continuity (infinite resistance). If there is continuity to ground, the element is shorting and should be replaced. Exact resistance depends on element wattage and voltage; the test is primarily for continuity and absence of ground short.
What electrical specifications (voltage, wattage, expected resistance) should I expect for this element?
Most residential electric oven elements for U.S. models are designed for 240 VAC. Wattage varies by application (commonly 1000-4000 W depending on bake vs. broil and oven design). Resistance can be estimated by R = V^2/W if you know the wattage (for example a 240 V, 3000 W element ≈ 19.2 ohms). Because the exact wattage for part 318254902 depends on the oven model,check the oven’s service manual,the part listing,or the label on the old element for the precise rating rather than relying on a single nominal number.
How do I replace the 318254902 oven element safely and correctly?
Turn off power at the circuit breaker and verify power is off. Remove oven racks and access the element (usually held by screws or a mounting bracket). Note or photograph wire positions, then disconnect the element’s quick‑connect terminals (use pliers if needed, avoid pulling on wires). Remove the old element and install the new one by reversing steps: secure mounting screws/bracket, reconnect terminals in the same positions, replace racks and restore power. After installation, test oven functions at a moderate temperature to verify proper operation. If you’re not comfortable working around mains voltage, hire a qualified technician.
Can a heating element like 318254902 be repaired if it’s damaged?
Heating elements are designed as sealed units and are not generally repairable. Visible damage (breaks, holes, corrosion) or an open circuit means the element should be replaced. Attempting to patch or weld an element is unsafe and unreliable.Replace with an OEM or equivalent rated element that matches the original specifications.
What safety precautions should I take when removing or testing the 318254902 element?
always disconnect power at the breaker and verify the circuit is de‑energized. Wear gloves and eye protection to avoid cuts on sheet metal edges. Allow the oven to cool fully before starting work. when testing with a multimeter, isolate the element from the oven wiring to avoid false readings and accidental shorting. Reconnect wiring only after confirming correct terminal placement. If you detect burning odors, smoke, or melted insulation, stop and contact a technician.
Where can I buy a genuine 318254902 replacement and is there a warranty?
You can purchase the 318254902 from Frigidaire/Electrolux parts departments, authorized appliance dealers, or reputable online appliance parts retailers. When buying, look for OEM (original equipment manufacturer) listings or authorized aftermarket equivalents. OEM parts typically carry a limited manufacturer warranty-check the seller’s warranty policy and Frigidaire’s parts warranty terms.Keep receipts and part numbers for warranty or return purposes.
