318255103 BAKE ELEMENT 2300W OEM
318255103 BAKE ELEMENT 2300W OEM is a resistive heating element intended for use as the primary bake heater in electric cooking appliances. The component is an OEM replacement part consisting of a tubular resistance element (typically a NiCr resistive core within a stainless-steel sheath, insulated with magnesium oxide) designed to convert electrical power into radiant and convective heat at a rated output of 2300 watts.
Inside an oven or range,the bake element provides the controlled heat source for the bake cycle and interfaces directly with the appliance’s power delivery and temperature control systems.it is switched by the appliance control board or a mechanical thermostat/relay, monitored indirectly by the oven temperature sensor (thermistor or thermocouple), and protected by over‑temperature cutouts and fuses. Mechanically it mounts in the oven cavity, connects to the appliance wiring harness via insulated terminals, and is exposed to the oven habitat, so terminal integrity, grounding and sheath condition affect both performance and safety.
In the following article readers will find a technical overview of the part’s function and construction, guidance on electrical and mechanical compatibility (including how wattage and supply voltage determine current draw and cold resistance), common failure symptoms (open circuit, short to ground, uneven heating, burned terminals), step‑by‑step troubleshooting checks (visual inspection, continuity and resistance measurements, verifying control signals and protective devices), and practical replacement considerations such as matching mounting style, terminal type, wattage rating, and safety procedures for disconnection and reassembly.

Function and Role of the Bake Element Within Oven Heating Systems
The 318255103 BAKE ELEMENT 2300W OEM is a resistive heating element that converts electrical energy into heat for the oven’s bake cycle. At its rated power and nominal supply voltage (approximately 230 V), its nominal resistance can be estimated by R = V²/P, which yields about 23 ohms; this value is useful for bench verification with a multimeter. Functionally the element supplies the majority of radiant and convective heat to the cavity and interacts directly with the oven thermostat or electronic control board and switching device (relay/triac) to produce controlled thermal cycles and maintain setpoint temperature during baking operations.
The element’s behavior during use depends on watt density, sheath material, placement in the cavity, and the oven’s airflow pattern; these factors determine heating speed, surface browning, and temperature uniformity. Compatibility for replacement requires matching electrical rating, physical mounting and terminal style, and sheath length-mismatches can produce slow preheat, inaccurate temperature control, or control board fault codes.Technicians typically diagnose faults by inspecting for visible damage, performing continuity and insulation-to-ground checks, and comparing measured resistance to the expected value; common symptoms of a degraded or failed element include extended preheat times, uneven browning, open-circuit readings, or nuisance trips of protective devices.
- Primary roles: radiant heating and working with controls for temperature regulation.
- Diagnostic checks: continuity/resistance measurement, insulation-to-ground test, visual inspection.
- Replacement factors: match wattage, voltage, mounting flange, and terminal configuration.
- Failure indicators: open circuit, short to ground, blistered sheath, uneven oven performance.

How the 318255103 BAKE ELEMENT 2300W OEM Operates Within Oven Electrical and Thermal Systems
The 318255103 BAKE ELEMENT 2300W OEM is a resistive heating element designed to convert electrical energy into radiant and convective heat within the oven cavity. Physically, it mounts under the oven floor or at the rear of the cavity and presents as a coiled resistance housed in a metal sheath; electrical feed-throughs are normally spade terminals or sealed studs. Electrical behavior follows Ohm’s law and basic power relationships: at 230 V the element’s steady-state resistance is approximately 23 Ω (R = V²/P), giving a nominal current draw near 10 A. Matching the element’s wattage, resistance, and terminal layout to the oven’s control and mounting system preserves the oven’s thermal response and prevents thermostat cycling anomalies or excessive load on relays and wiring.
- Power rating: 2300 W – determines heat-up rate and control setpoint behavior
- operating voltage: typically 230-240 V; design must suit supply voltage
- Approx.resistance: ~23 Ω @ 230 V – useful for continuity checks
- Terminations: spade or stud; OEM dimensions ensure mechanical fit
- Nominal current: ~10 A; circuit protection typically sized higher to cover other loads
| Item | Description |
|---|---|
| Power rating | 2300 W – determines element heat flux and oven temperature rise |
| Approximate resistance | ~23 Ω at 230 V (calculated); use multimeter to confirm continuity |
| Connector type | Standard spade terminals or sealed studs; match OEM mounting for safe replacement |
In the oven electrical and thermal system the element is driven by the control module or thermostat through relays or solid-state switching devices; duty cycle and cycling frequency are set by the control algorithm and the oven’s thermal mass. Thermal interactions include conduction to internal surfaces, radiation to cookware, and convective mixing when a fan is present – a correctly rated element provides the expected bake curve, while a degraded or mismatched element can cause slow heat-up, uneven browning, or premature thermostat cycling. Technicians commonly verify element condition by measuring cold resistance (expect the calculated value within tolerance), checking for insulation-to-ground faults, and confirming that control relays supply full line voltage; an open element requires replacement, while a short to ground mandates immediate service and verification of wiring and protective devices.
Common Failure Symptoms and Diagnostic Indicators of Bake Element Degradation
The 318255103 BAKE ELEMENT 2300W OEM is a tubular heating element designed to convert electrical power into radiant and convective heat for the oven cavity; at its rated 2300 W the element will present a cold DC resistance in the mid-20 ohm range when operated on typical 230-240 V household supplies. Functionally it must match the oven’s mounting, terminal type, and voltage rating to restore correct watt density and thermal response; mismatched length, terminal spacing, or wattage changes will alter heat distribution and may cause control or safety devices to operate out of specification.Degradation of the element typically occurs through internal wire breakage, sheath oxidation, or insulation breakdown that reduces effective power output, causes localized overheating, or allows leakage current to the chassis, all of which produce distinct operational symptoms technicians can observe and measure.
- Complete loss of heating (infinite resistance between terminals indicating a break in the element).
- Slow preheat and uneven baking (partial element failure or increased resistance lowering delivered wattage).
- Visible blistering, discoloration, or arcing at terminals indicating sheath failure or loose connections.
- Repeated tripping of thermal cutouts or circuit breakers (possible leakage or short to chassis).
- Odors or smoke during operation localized to the element area (insulation breakdown or embrittled sheath).
| Item | Description |
|---|---|
| expected cold resistance | Approximately 23-25 Ω for 2300 W at 230-240 V; notable deviation suggests degradation or incorrect part rating. |
| Continuity test | Multimeter between terminals should show low finite resistance near the calculated value; infinite/open indicates a broken element. |
| Insulation/ground leakage | Resistance from terminal to chassis should be very high (ideally megohms); measurable continuity to chassis indicates leakage or sheath failure. |
When diagnosing, isolate power and perform a terminal-to-terminal resistance check first, then a terminal-to-chassis insulation check; an element that reads much higher then the expected resistance will produce reduced heat and long preheat times, while a lower-than-expected reading or continuity to chassis indicates a short or leakage path that can trip breakers. For practical replacement decisions, confirm that the replacement 318255103 BAKE ELEMENT 2300W OEM matches the oven’s terminal type, mounting brackets, and voltage rating; if measurements or visual inspection show brittleness, sheath breaches, or abnormal resistance values, replacement with the correct OEM-specified element restores original thermal characteristics and safer operation.
Replacement Considerations and Step-by-Step Installation Procedures for the 318255103 BAKE ELEMENT 2300W OEM
The 318255103 BAKE ELEMENT 2300W OEM is a resistance heating element designed to provide the primary radiant heat in the oven cavity; its 2300 W power rating implies operation on typical household higher-voltage circuits (nominally 230-240 V). When evaluating replacement compatibility, match the element’s terminal type, mounting flange spacing, and electrical rating to the original part; mismatched terminal spacing or a different wattage can change heat-up time and temperature distribution. You can estimate the element’s cold resistance from R = V²/P - for example,at 240 V the expected resistance is about 25 Ω (≈24-26 Ω tolerance depending on construction),so measuring continuity and comparing resistance with the original part helps confirm correct specification before installation.
Follow a controlled procedure for replacement to avoid damage and ensure safe operation: disconnect power at the breaker and use a multimeter to verify absence of voltage at the oven terminals before touching wiring. Remove oven racks, detach the back or bottom access panel as required, note the wire routing and any insulating sleeves, unscrew the element mounting screws, and gently pull the element forward to expose the spade terminals.Reinstall the new element in reverse order, secure mounting hardware so the tube does not contact the oven walls, reconnect insulated terminals firmly, replace panels, and perform a test heat cycle while observing proper mounting and absence of smoke or arcing. Common troubleshooting checks after installation include verifying continuity, confirming the correct breaker/fuse rating, and monitoring that the oven reaches expected set temperatures within normal time for the model.
- Pre-checks: confirm OEM part number,measure old element resistance,inspect connectors and insulation.
- Safety: breaker off, multimeter voltage check, use insulated tools.
- Installation: align flange, secure screws, attach terminals, check clearances.
- Post-install: functional test, check for unusual odors, re-torque fasteners after cool-down.

Q&A
What is the 318255103 bake element and where is it used?
The 318255103 is an OEM oven bake (lower) heating element rated at 2300 W, designed for electric household ovens that use a 220-240 V supply. It supplies the primary radiant heat for baking and is typically mounted on the bottom interior of the oven cavity. To confirm fit, match the OEM part number, physical shape and mounting points, and terminal type to your oven model.
How can I tell if the bake element is failing or needs replacement?
Common signs of a failing bake element include no heat when in bake mode,uneven heating (hot spots or cold spots),visible damage such as blisters,cracks,breaks or burnt areas,sparking at the terminals,a burning smell,or the element tripping breakers. Before replacing, visually inspect the element and test electrically with a multimeter (see next question) to confirm an open circuit or a short to chassis.
how do I test the 318255103 element with a multimeter?
First disconnect power to the oven. Remove the element’s access panel or cavity screws so you can access and disconnect the wires. Set a digital multimeter to the low ohms range and measure resistance across the two element terminals; for a 2300 W element on 240 V you should see approximately 24-26 Ω (R = V²/P ≈ 240²/2300 ≈ 25 Ω) at room temperature. Then check each terminal to the metal chassis/ground-there should be no continuity (infinite/very high resistance). An open circuit (OL) across terminals means the element is broken; continuity to chassis indicates internal short/leakage and the element should be replaced.
What are the safe steps to replace this bake element?
Turn the oven power off at the breaker and verify power is off. remove oven racks and the access screws or rear panel to reach the element, disconnect the terminal wires (note their positions), remove mounting screws or retainers, and carefully pull the element out. Install the new 318255103 by reversing removal: seat the element, secure fasteners, reconnect wires using insulated connectors as original, restore panels and racks, then restore power and test on a short bake cycle. Avoid bending the element, touching sharp sheet-metal edges, and ensure terminals are insulated and not touching the oven body.
What resistance and electrical specifications should I expect for this 2300 W element?
The element is specified at 2300 W for use on 220-240 V circuits.Its cold resistance is approximately 24-26 ohms when measured at room temperature on a 240 V system (calculated R = V²/P). Expect the resistance to increase significantly when the element is hot. Do not attempt to measure live voltage across the element with a multimeter except when you know what you are doing-prefer voltage checks with appropriate safety precautions if diagnosing control or supply issues.
Can I substitute a non-OEM element or use a different wattage?
You can substitute with an aftermarket element that matches the OEM part number,terminal type,mounting,dimensions,and wattage. Do not use an element with higher wattage than specified for your oven-higher wattage can overload thermostats and wiring and change cooking performance. A lower-wattage element may not reach temperatures properly. When in doubt, match the OEM number (318255103) or consult the oven manufacturer for approved replacements.
Why might my oven still not heat properly after replacing the bake element?
If the new element tests good but the oven still won’t heat properly,possible causes include a faulty bake relay or control board,a bad oven temperature sensor/thermostat,wiring/terminal connection issues,a blown thermal fuse or safety thermostat,or incorrect selector switch operation (e.g., set to broil instead of bake). verify correct voltage is reaching the element, check the oven sensor resistance and control board functions, and inspect wiring and connectors for damage.
Is there any special maintenance or care to extend the life of the bake element?
Avoid abrasive cleaning that can damage the element surface; clean spills promptly to prevent corrosive residue from degrading the sheath. Do not contact the element with metal utensils and be careful when removing racks to avoid bending or striking the element. Regularly inspect for visible damage and address any sparking or unusual smells immediately-replace the element if any sheath damage or electrical leakage is suspected.
