318255006 Frigidaire Oven Range Bake Element is a tubular resistive heating element used as the primary bake heater in electric Frigidaire ovens and ranges. physically, it is a metal-sheathed (tubular) element that contains a resistance coil and insulating fill; it mounts to the oven cavity (typically on the back wall) and connects to the range’s power terminals via insulated studs or a terminal block.
Inside the appliance, the bake element’s role is to convert electrical energy into radiant and convective heat for the bake cycle. It is energized by the oven control (mechanical thermostat, electronic control board, or relays/SSRs) and works in conjunction with the oven temperature sensor/thermistor, door seals, and the cavity interior to achieve and maintain set temperatures. Proper electrical connections, correct voltage rating (commonly the appliance supply nominally in the 208-240 V range), and intact insulation/grounding are critical for correct operation, temperature uniformity, and electrical safety; faults in the element can affect control logic, cause uneven cooking, or create hazardous conditions such as short-to-ground or arcing.
This article will explain the bake element’s construction and operating characteristics, how to determine compatibility with specific Frigidaire models, common failure modes and diagnostic symptoms (open circuit, short-to-ground, visible damage, overheating, or poor heat output), and practical troubleshooting steps for technicians, engineers, and informed appliance owners-including safe power isolation and multimeter checks. It will also cover replacement considerations such as matching electrical ratings and mounting configurations, handling and installation best practices, and verification tests to confirm a successful repair or replacement.

Function and Role of the Bake Element in oven Heat Generation and Temperature Uniformity
The 318255006 Frigidaire Oven Range Bake Element is a resistive heating component that converts electrical energy into radiant and convective heat to create and maintain the oven’s bake temperature. Physically mounted at the bottom of the oven cavity, the element heats as current passes through its resistive alloy and radiates heat upward while also transferring energy to the air that the oven’s natural or forced convection distributes. The oven controller cycles line voltage to the element to regulate temperature; this on/off duty cycle, combined with the element’s wattage and placement, largely determines how quickly the oven recovers temperature after a door opening and how even the heat distribution will be across racks and bakeware. Replacement compatibility requires matching terminal type, mounting bracket spacing, and rated wattage/resistance to preserve control calibration and prevent over- or under-heating when substituting parts.
functionally, bake elements influence temperature uniformity through radiant flux and their interaction with airflow: a properly specified element provides a stable base temperature and predictable thermal gradients, whereas a degraded or mismatched element can cause hot or cool spots and longer recovery times. Technicians commonly verify operation by checking continuity with a multimeter and calculating expected resistance using the power-voltage relationship (R = V² / P) to confirm the element’s wattage rating; a confirmed open circuit or a short to chassis indicates failure. During installation, ensure secure electrical connections, intact insulation at the terminal block, and that the replacement element’s wattage matches the oven’s control design to avoid nuisance cycling or control inaccuracies.
- Common symptoms of element issues: no heat (open circuit), uneven bake, visible blistering or break-through, tripping breakers (short to ground).
- Compatibility checks: terminal type, mounting spacing, rated voltage and wattage, and physical length/shape.
- Practical tests: continuity check,resistance comparison using R = V² / P,and visual inspection for hotspots or breaks.

How the 318255006 Frigidaire Oven Range Bake Element Operates Electrically and Thermally Within the Appliance
The 318255006 Frigidaire Oven Range Bake Element is a tubular resistive heater that converts electrical energy into thermal energy via Joule heating. When the oven control supplies the element with line voltage, current passes through a nichrome resistance coil embedded in magnesium-oxide insulation and enclosed by a stainless‑steel sheath; the resulting heat is radiated into the oven cavity and conducted to cookware. the element is switched by the oven control board, mechanical thermostat, or a relay/triac, so its electrical behavior is best understood as a resistive load that is periodically cycled to maintain setpoint temperature. Proper electrical function requires intact continuity between terminals, correct line voltage at the harness, and secure terminal/mount compatibility with the appliance wiring harness and mounting brackets.
- Continuity check with power off to detect open-circuit failure.
- Verify terminal voltage with power on (use caution) to confirm control/relay operation.
- Inspect for visible breaks, blistering, or grounding of the sheath indicating thermal fatigue or shorting.
- Confirm physical fit: terminal type,mounting tab position,and element length must match the oven for correct heat distribution.
Thermally, the element exhibits relatively fast surface heating and then radiates and convects heat into the cavity; its thermal time constant and cycling duty determine how uniformly the oven tracks temperature setpoints. Repeated thermal expansion and contraction stress the internal coil and insulation, so common failure modes are open circuits or localized hot spots rather than gradual loss of resistance. For practical troubleshooting, an open reading on a multimeter signals element replacement, whereas correct resistance with no heat at runtime suggests a control, relay, or supply issue. When replacing the part, match the element’s electrical rating, terminal configuration, and mounting geometry to maintain safe operation and expected baking performance.

Common Failure Symptoms and Performance Indicators of a Failing Bake Element
The bake element is the primary resistive heating component that provides radiant and convective heat from the bottom of the oven cavity. The 318255006 Frigidaire Oven Range Bake Element is a direct replacement-style part used in many Frigidaire ranges; its function is purely resistive, converting line voltage into heat when the control element closes the circuit. Common failure mechanisms include open-circuit breaks in the internal coil, insulation breakdown causing shorts to the mounting bracket or chassis, and surface damage such as blistering or corrosion that changes heat distribution. Behaviorally, a healthy element will glow uniformly and allow the oven to reach and hold set temperatures, while a failing element may produce insufficient heat, uneven hot spots, or electrical faults that affect oven controls or trip breakers.
Technicians should verify element condition with a visual inspection and electrical measurements before replacement: a continuity check with a multimeter identifies open circuits, and a resistance reading gives a rough indication of element integrity (values vary by wattage and design). Practical examples include an oven that preheats very slowly (suggesting reduced output),or one that heats only on one side (indicating a partial internal failure or localized corrosion). Because compatibility depends on terminal type, element length, mounting bracket location, and rated wattage/voltage, confirm these physical and electrical parameters match the oven model before installing the 318255006 Frigidaire Oven Range bake Element as a replacement.
- No heat at all or oven fails to reach set temperature.
- Uneven baking, localized hot spots, or one-sided heating.
- Visible breaks, blistering, or corrosion on the element surface.
- Circuit breaker trips or evidence of short to chassis ground.
- Longer-than-normal preheat times without thermostat or sensor errors.

Compatibility, Replacement Considerations, Step‑by‑Step Installation, and Diagnostic Checks
The 318255006 Frigidaire Oven Range Bake Element is a straight-replacement heating element designed for many frigidaire electric ranges that use a rear-mounted U-shaped bake element. Compatibility depends on terminal type and spacing, mounting ear configuration, rated voltage and wattage, and physical length. confirm that the replacement has the same two-terminal configuration, identical mounting ear positions, and the equivalent voltage/wattage rating to avoid under‑ or over‑heating; mismatched wattage changes oven recovery time and can stress the control board or wiring. For practical verification, compare the old element’s terminal spacing and measure cold resistance with a multimeter-cold resistance for typical 240 V bake elements commonly falls in the ~15-40 Ω range depending on wattage-then confirm the replacement matches those parameters and fits the oven cavity without bending or forcing the element into position.
- Disconnect power before any continuity or insulation tests.
- Inspect for visible breaks, blistering, or arcing at the terminals.
- Measure continuity between the two element terminals (should show low resistance) and check for no continuity between each terminal and chassis/ground.
- Verify terminal spacing and mounting ear alignment against the oven cutout before final installation.
- After installation, apply power and run a short bake cycle to confirm even heat and no tripping of breakers or control faults.
| Item | Description |
|---|---|
| Part number | 318255006 - OEM Frigidaire bake element,check OEM cross-reference for exact model matches |
| Terminal type | Two flat spade terminals (verify spacing and orientation) |
| Typical cold resistance | Approximately 15-40 Ω for 240 V elements (varies with rated wattage) |
| Mounting style | Rear-mounted U‑shape with two mounting ears; confirm fit to existing bracket |
installation proceeds by removing the oven back panel or access panel,carefully documenting or photographing wiring and terminal positions,unplugging the element leads,and extracting the old element from its mounting ears. with the new element in place, tighten mounting hardware without over‑torquing, reconnect the spade terminals ensuring tight, corrosion-free connections, and restore power only after verifying there is no continuity to chassis ground; if a live-voltage verification is required to confirm 240 V at the element, perform that test with insulated tools and appropriate PPE or defer to a qualified technician. Post‑installation diagnostics include observing element behavior during a controlled heat-up (element should heat uniformly, not arc), confirming oven control cycles correctly, and re-checking for absence of leakage to ground-if breakers trip or control faults persist, inspect wiring harness, relay/contactors, and the oven control for faults before assuming element failure.
