318255006 Frigidaire Oven Range Bake Element is a replaceable tubular resistive heating element designed for the bake circuit of Frigidaire electric ranges. It is a metal-sheathed electrical heater that mounts inside the oven cavity, terminates in two power connectors, and converts electrical energy to heat to produce the steady radiant and convective heat required for baking. As a component, it is a straightforward resistive load but must match the appliance’s mechanical and electrical interfaces to function safely and predictably.
Inside the appliance the bake element is the primary heat source for the bake mode and interfaces directly with the range’s power supply, the user control board or mechanical thermostat, and several safety devices such as thermal cutoffs and door interlocks. Proper operation depends on secure electrical connections, intact sheath insulation and mounting, and coordination with the oven’s temperature sensing and control system; failures can affect temperature regulation, cause tripping of protective devices, or create an electrical fault. The element is typically located at the bottom of the oven cavity in residential Frigidaire electric ranges and is critical to achieving uniform cavity temperatures and reliable bake performance.
In this article readers will find a technical examination of the bake element’s function,electrical and physical compatibility considerations,common failure symptoms (such as loss of heat,intermittent operation,visible damage,or short-to-ground),and practical troubleshooting steps a technician can use such as continuity checks and voltage verification. the piece will also cover replacement considerations-matching part number, terminal style, mounting configuration, and ratings-and safety precautions to take when servicing the bake circuit so appliance owners and service professionals can make informed repair decisions.

Function and Role of the Bake Element in Oven Heat Generation and Temperature Regulation
The 318255006 Frigidaire Oven Range Bake Element converts electrical energy to thermal energy via resistive heating, forming the primary heat source for the lower oven cavity. Mounted at the oven floor or rear under the baking surface, the element heats its metal sheath and radiates/convects heat into the cavity; the control system modulates power to this element using an infinite switch, relay, or solid‑state controller and a temperature sensor (thermistor/thermostat) to maintain the setpoint. proper operation depends on matching the element’s voltage and wattage to the oven’s control and load characteristics-incorrect watt density or terminal configuration alters warm‑up rate, temperature recovery after door openings, and uniformity across racks.
Functional failures usually present as open circuits, short-to-ground, or localized sheath breakdown that produces hotspots and impaired heat distribution; technicians verify condition with a continuity check and compare measured cold resistance to the expected range for the oven’s rated voltage. Replacement compatibility requires matching electrical rating, overall length, mounting bracket and terminal style so the control timing and thermal mass remain consistent; for example, swapping in the correct factory part preserves designed heat‑up times and sensor calibration, while a mismatched high‑wattage element can cause overshoot or shortened component life. For safe diagnostics and replacement always disconnect mains power and follow manufacturer service procedures.
- Common symptoms: no heat (open circuit), uneven baking (partial failure or sheath corrosion), tripping breakers (short to ground).
- Replacement checklist: voltage rating, wattage, element length, terminal type, mounting position.

how the 318255006 Frigidaire Oven Range Bake Element Works Inside the Appliance’s Electrical and Thermal Systems
The 318255006 Frigidaire Oven Range Bake Element is a resistive heating element that converts mains electrical power into thermal energy and serves as the primary heat source for the oven’s bake function. Electrically it is a low-inductance resistive load that is energized by the oven control through a relay or triac; applied voltage and the element’s cold resistance determine steady-state wattage according to P = V^2/R. Thermally, heat is transferred from the tubular element to the oven cavity by a combination of radiation and conduction (direct contact with oven floor and reflected from surfaces), and the element’s thermal mass and placement determine the time constant for preheat and recovery after door openings.Control systems regulate average oven temperature by cycling the element on and off; engineers and technicians should expect cyclical temperature overshoot/undershoot related to control algorithm tuning and the element’s thermal inertia rather than a change in element performance alone.
- Electrical interface and behavior: two insulated spade terminals, nominal 240 V operation in North American ranges, resistive heating that scales with applied voltage.
- Common failure modes: open circuit (no heat), short to chassis ground (trips breaker/GFCI), localized burn spots causing uneven heating.
- Diagnostic methods: measure cold resistance with a multimeter and check for continuity to chassis, inspect mounting and terminals for corrosion or loose connections.

Compatibility is largely mechanical and electrical: replacements for the 318255006 Frigidaire Oven Range Bake Element must match terminal spacing, mounting bracket, and rated voltage/wattage to preserve oven control behavior and safety margins. In practice, technicians confirm compatibility by comparing physical dimensions and measured resistance to manufacturer specifications and by verifying that the control board or relay supplies correct voltage when the bake cycle is commanded. Such as, if a bake cycle is selected and the control board outputs no voltage to the element but the element shows correct continuity, the fault is in the control/relay rather than the element; conversely, an open element with correct control voltage indicates the element needs replacement. Performing these checks prevents needless replacements and ensures the oven’s electrical and thermal systems remain properly matched.
Common Failure Symptoms and Diagnostic tests for Bake Element Degradation
The 318255006 Frigidaire Oven Range Bake Element is the tubular resistive heater that supplies the primary radiant heat for the oven cavity; it is typically a 240VAC direct-replacement element rated for the oven’s specified wattage. Normal operation presents as an even orange-red glow along the entire length of the sheath and a steady resistance consistent with the element’s wattage. Degradation occurs as internal coil breaks, sheath corrosion, or breakdown of the internal insulation, which can produce localized hot spots, reduced heating output, intermittent operation, arcing to the chassis, or nuisance tripping of protective devices. Compatibility with a given Frigidaire range depends on mounting dimensions, terminal type, and wattage rating rather than cosmetic shape, so matching those technical specs is necessary when assessing replacement suitability.
Diagnostic tests begin with disconnecting power and a visual inspection for blistering, breaks, discoloration, or arcing marks.Electrical tests include a continuity/ohms measurement across the element terminals and an insulation-to-chassis test: a healthy bake element will show low, stable resistance across terminals and no continuity between either terminal and the metal sheath (open to chassis). As a practical guideline, typical 240VAC oven bake elements measure in the tens of ohms (roughly 15-40 Ω depending on wattage); an infinite resistance indicates an open coil, a significantly higher-than-expected reading indicates partial coil degradation, and any continuity to chassis indicates a leakage/short. If bench measurements are inconclusive, verify supply voltage, oven control relays, and wiring harnesses before replacing the element, as similar symptoms can originate outside the element itself.
- Uneven baking or hot/cold spots in the oven cavity
- Element does not heat (no glow) while control indicates heating
- Element glows only intermittently or only in sections
- Tripping breakers or visible arcing to the oven chassis
- Visible blistering,breaks,or discoloration on the element sheath
| Item | Description |
|---|---|
| Typical terminal-to-terminal resistance | Approximately 15-40 Ω for common 240VAC bake elements (varies with wattage) |
| insulation-to-chassis | High/OL (no continuity). Any continuity indicates leakage/short. |
| Visual indicators | Blistering, ruptures, discoloration, or arcing marks suggest sheath failure. |
Compatibility,Replacement Considerations,and Step-by-Step Installation Procedure
The 318255006 Frigidaire Oven Range Bake Element is a direct-resistance heating element that provides radiant heat from the oven floor to the bake cavity; its proper behavior is characterized by continuous metallic resistance with no leakage to chassis and uniform heat output across its length. Compatibility is determined primarily by electrical rating, terminal style and spacing, and mounting flange geometry-elements with the same OEM part number will match these parameters, but technicians should confirm voltage rating, stud/plug type, and physical length before replacement. Common failure modes include an open circuit (no continuity), resistance-to-ground (shorting to chassis), or localized hot spots from internal breaks; diagnosing these requires a visual inspection for burns or blisters and electrical tests with a multimeter to measure continuity and insulation resistance prior to ordering the replacement element.
- Verify OEM or cross-reference part number and measure terminal spacing and overall length.
- Check terminal type (quick-disconnect vs. bolt studs) and mounting flange orientation.
- Symptoms to confirm: no heat during bake,uneven browning,visible blistering or arcing,or a tripped breaker.
- Required tools: insulated screwdrivers, multimeter, needle-nose pliers, and appropriate replacement grommets or insulators.
| Item | Description |
|---|---|
| Voltage | Matches oven supply (typically 240 V for ranges); confirm before install |
| Terminal Type | Quick-disconnect or threaded studs; must match appliance harness |
| Failure Modes | Open circuit, short to chassis, or localized breakdown from overheating |
For replacement, first disconnect power at the breaker and verify absence of voltage at the oven terminals with a meter; remove oven racks for access, then remove the fasteners securing the bake element to the rear or side flange and carefully pull the element forward to expose the terminal connections. Note the wiring orientation, detach the terminals (use pliers if necessary for tight connectors), and inspect mounting grommets or insulation-install the new element only if terminal spacing and mounting flange align; reconnect the terminals, secure the element with the original fasteners, restore grommets to prevent chassis contact, and reapply power to perform a test bake while observing for correct heat-up and absence of arcing or tripped protection. If the new element shows continuity but trips breakers or exhibits leakage to chassis, remove power and verify insulation resistance or consult a qualified technician before continuing.
Q&A
What models is the Frigidaire bake element 318255006 compatible with?
318255006 is an OEM Frigidaire replacement bake element used in a range of Frigidaire/Frigidaire Gallery ovens and some affiliated brands. Compatibility depends on the oven model number – always verify by entering your oven’s full model number on the frigidaire parts lookup or a reputable appliance parts site before ordering. Do not rely on visual similarity alone.
What are the common symptoms that the bake element is failing?
Common symptoms include the oven not heating or heating very slowly, uneven baking, visible cracks or blisters on the element, visible burn-through, a burning smell when the oven is off, or the circuit breaker tripping when the oven is used. Some faults are intermittent (works sometimes, fails other times).
How do I test the bake element with a multimeter?
First turn off power at the breaker. access the element terminals (usually by removing oven racks and the rear/inside fasteners) and disconnect the wires. Set the multimeter to continuity or low ohms and measure between the two element terminals – a good element will show continuity and a low resistance (usually in the low double-digit ohms for most 240V elements). Also test each terminal to the metal sheath (element body); those readings should be open/infinite (no continuity). Continuity to ground indicates the element is shorted and should be replaced.
How do I safely replace the 318255006 bake element?
safety first: disconnect power at the main breaker. Remove oven racks, locate and remove the mounting screws or bolts that secure the element (often at the back interior), gently pull the element forward to expose the wire terminals, disconnect the push-on connectors, and remove the old element. Install the new element by reconnecting the wires to the corresponding terminals, secure the element with its mounting screws, replace racks, restore power, and test the oven at a bake setting. If you’re unsure or wiring looks damaged, have a qualified technician perform the replacement.
Can I use the bake element interchangeably with the broil element?
No - the bake (bottom) and broil (top) elements are designed for diffrent locations, mounting types, and heat loads. Broil elements typically radiate more directly and might potentially be a different shape or resistance. Use the correct OEM or approved replacement for each location.
Is it normal for the bake element to glow red during operation?
Slight red/orange glow can be normal at high temperatures, but bake elements frequently enough do not glow as brightly as broil elements as their heat is more radiant/conductive and spread over a larger surface. Shining,uneven glowing,visible hotspots,or sections that do not heat can indicate damage and require replacement.
Why does my circuit breaker trip when I turn on the oven?
A breaker trip can be caused by a short to ground in the bake element (element insulation failure), a shorted wire or terminal, or a failure elsewhere in the oven electrical system (control board, wiring harness). To isolate the element, turn power off, disconnect the element and test it for continuity to ground. If the element is shorted to ground, replace it. If the element is OK, further diagnosis by a technician may be needed.
How should I clean and maintain the bake element to extend its life?
Allow the oven to cool before cleaning. Light splatters can be wiped off with a soft cloth or non-abrasive sponge and mild detergent. For heavy spills, remove the element (after disconnecting power) and clean gently – do not bend or scrape the sheath aggressively. Avoid harsh chemical cleaners, metal scouring pads, or immersing electrical terminals in liquid. Regularly remove baked-on food from the oven floor and racks to reduce stress and hotspots on the element.
