318191000 Frigidaire Oven Switch is an electromechanical switch used as a replaceable control component in Frigidaire oven assemblies. It is indeed a circuit-actuating device-typically implemented as a microswitch or selector-type switch-designed to open and close electrical paths within the oven’s control and safety systems, and it is supplied as a service part for repair and maintenance tasks.
Within an appliance system the switch interfaces directly with the oven control board, power supply lines and the loads they govern (heating elements, internal lights, cooling fans or door interlocks), and it often provides a discrete on/off or signal input that the control electronics use to sequence operation. Its electrical ratings,contact configuration and physical mounting determine which circuits it can safely control; failures or poor connections at the switch can produce loss of heating,unintended operation,or incorrect status reporting to the control electronics,so its proper function is crucial for both performance and safety.
In the body of this article readers will find a clear description of the switch’s intended function and typical mounting locations (control panel or door assembly), guidance on compatibility and how to verify correct part selection (electrical ratings and connector type), common failure symptoms to watch for (open contacts, intermittent contact, stuck closed, visible damage), step‑by‑step troubleshooting methods (visual inspection, continuity checks with a multimeter, line-voltage verification and isolation procedures), and practical replacement considerations (matching part numbers, mechanical fit, connector orientation and safe power isolation practices during service).

Function and Role of the Oven switch in Temperature Regulation and Safety Systems
The 318191000 Frigidaire oven Switch is an electromechanical line-voltage switching component that routes mains power to the oven’s heating circuits under command from the temperature control or selector mechanism. in operation the switch provides discrete on/off and mode-selection functions (bake, broil, clean) and works together with the thermostat or electronic control to implement duty‑cycle temperature regulation: when the control calls for heat the switch closes the appropriate circuit to the heating element, and when the setpoint is reached the control opens the circuit to reduce temperature. The switch also serves as a primary isolation point for safety systems, allowing the control to remove power from high-current elements during fault conditions, self-clean cycles, or when a mechanical interlock is engaged.
- Routes line voltage to bake/broil elements and accessory circuits
- Implements on/off cycling used by thermostats and control modules for temperature regulation
- Provides a safety isolation point to disconnect elements during faults or clean cycles
- Requires matched terminal layout and voltage/current rating for direct replacement
| Item | Description |
|---|---|
| typical rating | Designed for household oven line voltage (up to 240 V) and sized for heating-circuit currents; verify manufacturer’s rating when replacing. |
| Terminal layout | multiple spade terminals for element and line connections; correct mapping of terminals to control and element leads is required for compatibility. |
| Common failure indications | No heat, intermittent heating, continuous heating, or visible arcing at terminals; confirm with continuity and visual inspection before replacing. |
For troubleshooting, verify continuity across the switch contacts in the expected actuator positions with a multimeter and inspect for burn marks or loose terminals; low contact resistance when closed and open circuit when actuated off are normal electrical behaviours.When replacing the switch, match the electrical ratings, terminal arrangement, and mechanical mounting to the original; mismatched ratings or incorrect wiring can cause control faults or safety hazards. In practical service scenarios, a failing switch can mimic control board or sensor problems, so confirm wiring, thermostat signals, and control outputs as part of a systematic diagnosis before installing a new 318191000 Frigidaire Oven Switch.
How the 318191000 Frigidaire Oven Switch interfaces with Ignition, Heating Elements, and Control Boards
The 318191000 Frigidaire Oven Switch is an electromechanical interface component that routes mains power between the oven’s control electronics, the igniter (or spark module on gas models), and the heating elements. In practice this switch completes or interrupts line-level circuits so the bake or broil element and the igniter receive full supply voltage when called by the control board or the front-panel selector. physically it presents a set of terminals for the incoming hot legs and the corresponding load outputs; understanding which terminal is ”line” vs. “load” is essential when tracing why an element or igniter is not energizing during a cook cycle.
Technically, the switch behaves as a high-current contactor: it must maintain low contact resistance under load and present predictable continuity when actuated. Compatibility considerations include terminal layout, voltage/current ratings (appliance mains, typically ~240 V AC), and mechanical fit with the oven’s knob or actuator. For troubleshooting, a service technician measures incoming voltage at the switch and continuity across the switch while the control board requests heat; a failed switch frequently enough shows no continuity when actuated or intermittent contact under load, which contrasts with control-board failures where the switch will measure correctly but no voltage is supplied to its line terminals. Practical replacement requires matching the terminal configuration and rating to avoid nuisance trips or open circuits.
- Primary functions: route mains to bake/broil elements, provide power to igniter/spark module, and serve as a user or control-board actuated selector.
- Common symptoms of failure: oven does not heat,elements remain cold while control board indicates demand,or intermittent heating cycles.
- Basic diagnostics: verify supply at the switch, check continuity when actuated, and inspect for burnt terminals or loose connectors.
| Item | Description |
|---|---|
| Function | Switches line-level power from incoming mains to heating elements or igniter circuits |
| Interface points | Line (incoming hot legs), Load (element/igniter outputs), ground/neutral reference as applicable |
| Typical electrical context | Appliance mains switching (~240 V AC in north American ovens) with appropriate current rating for bake/broil circuits |
| Diagnostics | Measure voltage at line terminals, continuity across switch when actuated, and inspect for physical damage or oxidation on terminals |
Common Failure Symptoms and Electrical/Mechanical Diagnostic Indicators for the Oven Switch
The 318191000 Frigidaire Oven Switch is the user-actuated contact assembly that routes line voltage to the bake and/or broil elements; it uses a rotary shaft or cam and discrete contact sets to select power paths. In properly functioning systems the switch provides low-resistance, positive connections when a given position is selected and isolates the circuit in off positions. As a replacement part it is physically and electrically compatible only with oven models that use the same terminal layout and mounting; technicians should confirm terminal numbering and shaft orientation against the original switch before installation. Practical examples of failure include a cooktop that will not heat on the bake cycle while broil still works (indicating a failed bake contact), or an oven that remains powered in the off position because a contact pair is welded closed from arcing or overheating.
- Intermittent or no heat on a particular function while other functions operate normally (suggests single-contact failure).
- Visible arcing, pitting or charring at terminals and contact faces (mechanical damage and degraded conductivity).
- High resistance or open reading across the expected closed contacts when tested with a multimeter at DC ohms with power removed.
- Continuity that appears only under pressure or with the shaft held in a certain position (worn cam or misaligned actuator).
- Unexpected energizing of elements in off positions (contacts welded or stuck closed).
Diagnostic procedure combines visual inspection with electrical verification: first de-energize the appliance and check for burnt terminals, loose spades, or broken actuator pieces; then measure continuity across the switch terminals in each selector position-closed contacts should show near-zero ohms, open contacts should show no continuity. For live-voltage troubleshooting (performed only by qualified personnel) measure AC voltage to the element feed terminal while rotating the switch to confirm the contact supplies mains when selected; any arcing observed during this test indicates replacement. Below is a quick reference for interpretation of common test outcomes to guide repair decisions.
| item | Description |
|---|---|
| Visual inspection | Look for pitted contacts, melted housing, discolored terminals; evidence of heat damage means replace. |
| Continuity test | With power removed, expected closed-contact reading = continuity (low ohms); open position = no continuity. |
| Operational test (live) | Measure AC at output terminal while selecting function; presence of mains only in correct positions confirms proper switching. |
Replacement Considerations, Model Compatibility, and Step-by-Step Installation Guidelines
The 318191000 Frigidaire Oven Switch is a mechanical electrical switch that routes line voltage to the oven’s heating circuits (bake, broil, or selector stages) according to the control shaft position. It contains multiple spade terminals and contact sets designed to handle the oven’s high AC current; contact wear, carbon build-up, or loose terminals will produce symptoms such as intermittent heating, buzzing, arcing, or a failure to reach set temperature. Technically, diagnosis should include visual inspection of contacts and terminals, continuity checks across switch positions with a multimeter, and verification against the oven’s wiring diagram to confirm which terminals are switched in each selector position.
For replacement and installation, choose a switch that matches the original part number or has an identical terminal layout, shaft diameter/length, mounting pattern, and electrical rating; mismatches in terminal arrangement or current rating can create unsafe conditions or miswire heating elements. Before disassembly, document wire locations (photos or a wiring diagram) and isolate mains power. Typical installation steps: remove access panels, detach wires from the old switch, transfer or align the shaft and mounting hardware, secure the replacement, and verify continuity in each selector position before restoring power. After power is restored, perform a controlled functional test at a low setting and confirm stable element operation and correct selector indexing.
- Disconnect power: turn off the oven at the breaker and verify no voltage at terminals.
- Document wire positions; label or photograph connectors for reassembly.
- Remove access panels and unscrew the switch from its mounting bracket.
- Transfer or match the control shaft/knob orientation and secure the new switch.
- Reconnect wires to the correct spade terminals and verify continuity across positions.
- Reassemble panels and perform a low-power functional test to confirm correct operation.

Q&A
What is the Frigidaire part 318191000 and what does it do?
Part 318191000 is a replacement control switch used on some Frigidaire ovens (function/selector or temperature-control style switches depending on model). It selects oven functions or regulates the oven control circuit. When the switch fails it can prevent the oven from heating, cause the oven to stay on, or make selected functions unresponsive.
How can I tell if the 318191000 switch is the cause of my oven problems?
Common symptoms of a failing switch include the oven not heating at all, heating only on one mode (bake or broil), intermittent operation, or the oven staying on constantly. Before replacing the switch, verify other components such as the thermal fuse, igniter (gas ovens), elements (electric ovens), thermostat/thermistor, and control board.Use the oven’s error codes and simple tests (visual inspection of wiring and elements) to narrow the cause.
Can I test the 318191000 switch at home and how?
Yes. Turn off and lock out power to the appliance first. Remove the control panel to access the switch and note or label the wire connections. Use a multimeter set to continuity or resistance (ohms). With the switch in different positions,check for continuity between the expected terminals according to the oven wiring diagram or service sheet. If the switch shows no continuity where it should, or shorts where it should be open, it is indeed likely faulty. If you are not confident interpreting readings or identifying terminals, consult a technician.
