318601500 Frigidaire Oven Control is an electronic control module used in a range of Frigidaire ovens adn ranges; it serves as the appliance’s primary control board and user-interface controller, managing timing, temperature setpoints, and user input interpretation. As a circuit assembly that typically includes a microcontroller, display/keyboard interfaces, and power switching components, the 318601500 replaces or interfaces with the original factory control that governs oven operation.
Inside the appliance, the control coordinates inputs and outputs across multiple subsystems: it reads temperature inputs from the oven sensor (thermistor or probe), interprets commands from the keypad or touchpad, drives the display, and switches power to heating elements or ignition systems via relays, triacs, or solid-state drivers. It also integrates with safety and interlock circuits (door lock, fuses, and over-temperature cutouts) and, where applicable, communicates with other modules such as convection fans or timed bake features. Proper function of the control is therefore critical to accurate temperature regulation, timing, and safe operation of the oven.
In this article readers will find a technical overview of how the 318601500 operates, guidance on determining compatibility with specific Frigidaire models and serial ranges, a summary of common failure symptoms and related error codes, diagnostic checks a technician can perform (visual inspection, sensor resistance checks, and output verification) and practical considerations for replacement including connector verification, handling precautions, and post-replacement checks. The focus will be on technical understanding and safe, methodical troubleshooting rather than promotional claims.

function and Role of the oven Control Board in Temperature Regulation and User Interface
The oven control board functions as the central control node for temperature regulation and the user interface. The 318601500 Frigidaire oven Control reads temperature feedback from the oven thermistor, executes the control algorithm (typically PID or timed bang‑bang logic depending on the model firmware), and actuates heating outputs through relays or solid‑state devices to maintain the setpoint. It also manages timers, keypad/display input, door-lock and safety interlocks, and stores fault codes in non‑volatile memory so technicians can diagnose faults. In normal operation the board continuously compares measured temperature to the setpoint, adjusts element duty cycle to reduce overshoot, and enforces safety timeouts and high‑limit shutdowns when thermistor or element behavior indicates a fault.
Practically, behavior and compatibility depend on both electrical wiring and firmware. Replacement or repair requires matching the part number or confirming connector pinouts, control logic, and sensor types; a mechanically identical board with different firmware can exhibit different fault thresholds, diagnostic displays, or feature sets.Technicians verify operation by measuring thermistor resistance against published tables, confirming line voltage to element outputs when the board commands heat, and observing stored error codes via the display. Common field checks and symptoms include:
- Display blank but clock/spare power present – check 5V/3.3V logic rails and connector power pins.
- Oven does not heat despite proper setpoint – verify relay/triac switching and measure element voltage when energized.
- Err codes or runaway temperature – inspect thermistor resistance and replace if out of tolerance, then confirm board fault logs.

How the 318601500 Frigidaire Oven Control Works Inside the Appliance: Components, Signal Flow, and Control Logic
The 318601500 Frigidaire Oven Control is the main printed circuit board that coordinates user inputs, timing, and power switching inside compatible Frigidaire ranges. Internally the board contains a low-voltage power supply, a microcontroller that runs the control firmware, driver circuits for display and keypad, and power switching devices (relays, triacs or solid-state relays) that energize bake, broil, convection fan and timer circuits. The board interfaces directly with the oven temperature sensor (typically a thermistor or RTD), door and safety interlocks, and-on gas models-the igniter/valve control chain; these interfaces determine whether the control will operate heating elements, open gas valves, or inhibit operation for safety faults. As the control combines logic, timing, and power switching, replacements must match the original part number and harness pinout to ensure correct voltages, switching behavior, and firmware compatibility with the oven’s sensors and actuators.
Signal flow through the control follows a closed-loop pattern: user command from the keypad or knobs is read by the microcontroller, which transitions the oven into a state (preheat, maintain temperature, broil, etc.) and executes a temperature-control algorithm (time-proportional control or PID-like duty cycling) that actuates the appropriate power switch outputs. Feedback from the temperature sensor is sampled continuously to modulate duty cycle and prevent overshoot; safety inputs such as the high-limit thermostat or door switch will immediately disable power outputs if they indicate a fault. Common practical failure modes illustrate this flow-no display but fan running points to the low-voltage supply or microcontroller reset; continuous cycling or inability to reach temperature often traces to a degraded thermistor or a failing relay/triac; constant heat with no control can indicate a shorted output device. Typical internal components and their functions are:
- microcontroller – runs the control logic and user interface
- Low-voltage power supply – provides regulated voltages for electronics
- Power outputs (relays/triacs/SSRs) – switch line voltage to heating elements,fan,or igniter
- Temperature sensor input – closed-loop feedback for temperature control
- Safety and interlock inputs – high-limit,door switch,and thermal cutoffs

Common Failure Symptoms and Diagnostic Indicators for Oven Control malfunctions
The oven control board manages user interface,timing,and power switching for bake and broil elements; failures of the 318601500 Frigidaire Oven Control typically alter those functions in measurable ways. Faulty output switching devices (relays, triacs or solid-state switches), corrupted firmware or broken connector pins will produce symptoms such as a blank or garbled display, persistent heating (element stays energized after cycle), failure to reach or hold set temperatures, and stored error codes. Compatibility matters: the 318601500 assembly must match the appliance harness and mounting, and swapping a visually similar board between models can introduce connector, sensor calibration or firmware mismatches that mimic control failure even when the board itself powers up correctly.
- Blank or intermittent display or touchpad response
- Element remains on or never energizes despite commands
- Oven temperature too low, too high, or erratic cycling
- Stored error codes or flashing indicators tied to sensor or relay faults
Diagnosis begins with isolating inputs and outputs: verify correct sensor resistance (oven thermistor values are typically around 1.1 kΩ at room temperature), check continuity of wiring and connector terminals, and measure line voltage at the control board output while commanding heat (expect line voltages in the 208-240 VAC range on residential ranges). Intermittent faults frequently enough point to cold solder joints, fractured traces, or connector abrasion; consistent over- or under-temperature typically indicates a bad sensor or a failed switching device on the control board. Use targeted tests (multimeter resistance and AC voltage checks, visual inspection for burnt components, and reading stored error codes) before replacing the board, since many symptoms can be resolved by repairing wiring, replacing the oven sensor, or reseating the harness.
| Item | Description |
|---|---|
| Blank display | Verify 120 VAC supply to display/backlight and check connector pins; may indicate failed power regulator on the board |
| Element never energizes | Command bake and measure voltage at element terminal; if voltage present, element is bad; if absent, suspect relay/triac or board driver |
| Incorrect temperature | Measure oven sensor resistance at ambient and compare to expected value (~1.1 kΩ); if sensor is correct, test control output duty cycle and relay switching |
Compatibility, Replacement considerations, and Step‑by‑Step Installation procedures for the Oven Control
The 318601500 Frigidaire Oven Control is a user-interface and power-control module that supervises bake/broil elements, the oven sensor, timers, and safety interlocks. It contains the control logic, relay/triac switching stages, and connectorized harnesses that mate to the oven’s temperature sensor (NTC), door lock, and heating elements; mismatches in connector pinouts or firmware revisions will prevent proper operation even if the board physically fits. Compatibility assessment should include checking the board’s connector layout and keying, the overlay/control-pad style, and any revision codes printed on the PCB - for example, two visually identical boards can differ in keypad scanning or error-code mappings, so confirm harness pin assignments and sensor wiring before installation.
Replacement requires basic electrical safety and careful verification of connectors and sensor continuity: disconnect power at the breaker,document connector locations with photos or labels,then remove the console fasteners and unseat the control assembly to access the harnesses. After swapping the board,verify the oven sensor with a multimeter (NTC sensors are typically around 1.1 kΩ at 25°C) and perform functional checks - bake, broil, and a temperature hold test – to confirm element switching and PID response; if error codes appear, re-check pin mapping and ground continuity. The following rapid checklist and reference table summarize common installation steps and critical specs.
- Safety: Disconnect mains and confirm zero voltage.
- label and photograph all harness connectors before disconnecting.
- Remove control fasteners, then gently release ribbon and Molex connectors.
- Transfer any mechanical parts (knobs,bezels) and reseat new board securely.
- Confirm oven sensor resistance and run bake/broil tests; monitor for error codes.
