Function and Role of the Surface Element in Heat Generation and cooktop Control Systems
The surface element performs the direct conversion of electrical energy into heat through a resistive conductor and is the primary heat source for an electric cooktop. The 318178110 Frigidaire Oven range Surface Element 6″ is a 6-inch resistive element designed to deliver its rated wattage when operated at the appliance line voltage; its resistance value,terminal type,and mounting geometry determine current draw and heat output. In stove control systems the element is controlled either by an electromechanical infinite switch or by an electronic relay/PWM stage; those controllers modulate power to regulate surface temperature by cycling the full line voltage on and off rather than varying the element resistance. Heat transfer behavior depends on element thermal mass and cookware contact-smaller elements heat faster but have lower total energy capacity than larger elements rated at comparable power.
Technicians diagnose element faults by measuring continuity and cold resistance, inspecting for visible damage or terminal arcing, and verifying compatibility with the cooktop’s control and terminal hardware. Common failure modes include open-circuit heating coils, degraded insulation causing leakage or arcing at terminals, and partial shorting that produces hot spots; symptoms are no heat, intermittent heating, or uneven cooking.When replacing an element, match the diameter, nominal wattage, terminal configuration, and mounting style to avoid overloading the infinite switch or changing heat distribution. Practical examples: a 6″ element that reads infinite resistance indicates an open coil and requires replacement; substituting an element with higher wattage than the original can trip control relays or shorten control life.

How the 318178110 Frigidaire Oven Range Surface Element 6″ Operates Electrically and Mechanically Within the Appliance
The 318178110 Frigidaire Oven Range Surface Element 6″ is a resistive, radiant heating element designed to convert mains electrical energy into heat through a nichrome or similar resistive coil enclosed in a metal sheath. Electrically it functions as a simple load: when voltage is applied across its terminals the coil draws current and dissipates power as heat (P = I×V).In typical installations the element plugs into the cooktop terminal block and is switched by an infinite (variable-power) switch or an electronic control; the control modulates the average power delivered by cycling the element on and off or by varying the duty cycle.Proper compatibility requires matching the physical diameter, terminal configuration, and wattage rating so the element seats correctly in the mounting flange, aligns with the terminal receptacle, and draws the expected current from the circuit.
- Resistive heating: converts electrical energy to radiant and conductive heat to cookware.
- mounting: flange and retaining clips hold the element in the cooktop opening; terminals plug into the range’s terminal block.
- Control interaction: power is provided by an infinite switch or relay; cycling behavior affects perceived heat output.
- Common failure modes: open circuit (no continuity), short to chassis, loose arcing terminals, or mechanical deformation that prevents proper seating.
| Item | Description |
|---|---|
| Element size | 6″ diameter sheath designed to fit corresponding cooktop opening |
| Electrical behavior | Resistive load; current flow produces heat; controlled by switch or electronic control |
| Mounting and connections | Flange, retaining clips, and two terminal receptacles that mate with the range terminal block |
| Field diagnostics | Use a multimeter for continuity (open circuit indicates failure) and insulation test to chassis (should be open) |
Mechanically the element must seat squarely in the cooktop aperture and maintain solid terminal contact; any loose spade or corroded terminal can create resistance heating at the connection point, causing arcing and uneven performance even when the element itself tests good. In practical troubleshooting, technicians measure cold resistance to confirm continuity, verify that there is no continuity between the element and chassis (ground), and confirm the control supplies the correct voltage under load. For example, if a 6″ element shows normal continuity but receives no power at the terminal when a burner selector is set, the likely causes are the infinite switch, wiring to the terminal block, or a failed safety interlock rather than the element itself; conversely, an open reading at the element indicates the element must be replaced with a unit matching the 318178110 Frigidaire Oven Range Surface Element 6″ specifications. Always disconnect mains power before testing or replacing components.
common Failure Symptoms and Diagnostic Indicators of a Faulty Surface Element
The 318178110 Frigidaire Oven Range Surface Element 6″ is a removable radiant cooktop element that converts electrical energy into heat through a resistive coil and sheath assembly. In normal operation the element presents a stable, low-resistance path between its two terminals, heats evenly across the visible coil, and interfaces with the cooktop receptacle or terminal block using standard spade connectors. Compatibility is determined by the element diameter, terminal spacing, and power rating; physically mismatched elements can exhibit poor contact, uneven heating, or premature failure even if the connector fits. Perform a visual check for broken coils, severe deformation, or burned insulation before electrical testing to reduce the chance of misdiagnosis.
Common failure symptoms include complete loss of heating, intermittent operation, localized hot spots, arcing or sparking at the terminal area, and breakers or fuses tripping when the burner is energized. Diagnostic indicators from bench testing are straightforward: a reliable multimeter continuity check that shows an open circuit (infinite resistance) indicates an internally broken element, while a low-resistance reading to chassis ground indicates insulation breakdown and a short to ground.If an element reads within an expected low-ohm range yet does not produce heat, the fault often lies upstream (loose spade connector, wiring harness, or infinite switch); conversely, if only one element on the range fails, that isolates the fault to the element or its immediate connections. Always de-energize the appliance before disconnecting connectors or measuring resistance.
- No heat / open circuit between element terminals – internal coil break.
- Intermittent heating or cycling – loose connector, failing switch, or partial coil contact.
- Arcing/sparking at terminals - corroded/burned connectors or cracked sheath.
- Tripping breakers when energized – short to ground or shorted coil.
- Visible deformation, discoloration, or hot spots – localized overheating or mechanical damage.
| Item | Description |
|---|---|
| continuity check | Low-resistance reading between terminals indicates intact coil; infinite indicates open element. |
| Ground insulation | Any continuity between a terminal and chassis ground indicates dielectric failure and requires replacement. |
| Visual signs | Broken coil, collapsed sheath, or burned terminal lugs point to mechanical or thermal failure. |
Compatibility, Replacement Considerations and Installation Procedures for the 6″ Surface Element
The 318178110 Frigidaire Oven Range Surface Element 6″ is a resistive heating element designed to deliver controlled heat to a cooktop zone; it converts electrical energy into heat via a coiled resistive conductor enclosed in a sealed tubular housing. Compatibility depends on three physical and electrical factors: the element’s nominal diameter (6″), the terminal style and spacing (plug-in spade, threaded stud, or screw terminal), and the element wattage/voltage rating. Functionally, the element must match the oven’s control device (infinite switch or relay) and the cooktop cutout or receptacle to avoid poor electrical contact, uneven heating, or nuisance failures. Technicians commonly verify compatibility by comparing the OEM part number, terminal configuration, and by measuring cold resistance with a multimeter to confirm it falls within the expected range for the rated wattage.
- Verify terminal type and spacing against the cooktop receptacle.
- Measure element diameter and length to confirm physical fit.
- Match wattage and voltage rating to the original element and control switch.
- Inspect insulating boots and mounting clips for secure electrical contact.
Disconnect power before performing any removal or replacement. Typical replacement steps: lift the element from the cooktop, slide the element back to access and disconnect the terminal connectors or remove mounting screws, swap the old element for the new one while preserving insulating boots and orientation, than secure terminals and restore the element to its mounting. After reassembly, verify continuity and that measured resistance corresponds to the element’s rated wattage (a rough reference for 240 V elements is tens of ohms depending on wattage); restore power for a short functional test and confirm incremental heat stages through the control knob. Use an exact-match part number or ensure terminal geometry and wattage are identical to prevent overheating, control mismatch, or premature failure.

Q&A
What is the Frigidaire 318178110 surface element and which ranges does it fit?
The 318178110 is an OEM Frigidaire 6″ electric surface (coil) element designed as a direct replacement for compatible Frigidaire/Frigidaire gallery/other electrolux-built ranges that use 6″ coil elements. Compatibility depends on the cooktop’s element socket/terminal style and the model year – always verify fit by checking yoru range model number or comparing the old element’s terminal type and mounting shape to the replacement before purchasing.
How do I confirm this 6″ element is the correct size for my cooktop?
Measure the element across its widest outer edges; a 6″ element measures approximately 6 inches from outer edge to outer edge. Also check the base/terminal assembly: the replacement must have the same plug-in spade terminal layout and flange shape so it sits correctly in the cooktop receptacle. If possible, compare the part number stamped on the old element to 318178110 or consult your appliance’s parts diagram.
What are the signs that this element (318178110) needs to be replaced?
Common failure symptoms include: the element does not heat at all,heats intermittently,heats unevenly or has cold spots,visible breaks or blistering in the coil,or arcing/sparking at the terminal area. Also inspect the receptacle under the cooktop – melted or discolored sockets often indicate the socket needs replacing even if the element looks fine.
Can I test the element before replacing it, and how?
Yes.First disconnect power to the range at the breaker. Remove the element and use a multimeter set to the ohms (Ω) range to check for continuity between the two terminals; a working heating element will show a finite resistance (not open/infinite). You can also calculate expected resistance from the element wattage and supply voltage using R = V² / P (such as, for a 1,500 W element at 120 V, R ≈ 9.6 Ω).If the meter reads infinite resistance (open circuit), the element is bad and should be replaced.
What is the correct procedure to replace the 318178110 element safely?
Turn the range breaker off and confirm there is no power. Remove the control knob and lift or remove the cooktop per your model’s instructions to access the element terminals. Pull the old element straight out from the terminal block (most are plug-in with 1/4″ spade terminals). Install the new element by seating the terminals into the receptacle and securing any clips or retaining hardware. Lower the cooktop, reinstall knobs, restore power, and test. If you are unsure at any step, hire a qualified appliance technician.
Do I need to replace any other parts when swapping the element?
Not always, but you should inspect the receptacle (terminal block) for heat damage and the control (infinite) switch for proper operation. If the receptacle is melted or the terminals are corroded, replace it – or else a new element will likely be fine. If the element still does not work after replacement, the infinite switch or wiring should be tested and may need replacement.
What type of electrical connection does this element use and what should I check electrically?
The 318178110 typically uses two flat spade (quick-disconnect) terminals that plug into the cooktop socket. Before installing, verify the terminal size and orientation match your range. Electrically, ensure the replacement matches the voltage and wattage requirements of your range. If you measure voltage at the socket (only if qualified), expect the proper supply (usually 120 V per leg for individual elements on some ranges or part of a 240 V system) - if voltage is missing at the socket while the switch is on, the problem might potentially be with the switch or wiring rather than the element.
Where can I get an authentic 318178110 part and is an aftermarket part acceptable?
OEM 318178110 parts can be purchased through Frigidaire parts distributors,authorized dealers,or reputable appliance parts websites using your range model number to confirm fit. Aftermarket/universal elements are often cheaper and can work, but you must match the physical dimensions, terminal type, and electrical ratings. OEM parts are recommended if you wont exact fit and original specifications.
