318601500 Frigidaire Oven Control is an electronic control module used in Frigidaire ranges adn wall ovens; it is indeed the appliance’s central control board that manages user inputs, timing, display functions, and the switching of heating circuits.Physically, the component is a printed circuit assembly mounted behind the oven control console or user interface and typically contains a microcontroller, power regulation circuitry, driver stages (relays or triacs), and connectors for sensors and harnesses.
Inside the appliance the control board coordinates multiple subsystems: it reads the oven temperature sensor, interprets keypad or touch-panel commands, sequences bake/broil/convection cycles, and switches outputs to heating elements, ignitors, fans, lights, and door locks. It also hosts firmware that implements control algorithms (temperature regulation, preheat and timer logic), monitors safety interlocks and fault conditions, and provides status and error reporting to the user interface. Electrically, it interfaces with mains power through input fusing and surge protection, low-voltage logic, and high-current switching stages, so proper interaction with sensors, harness connectors and grounding is critical for reliable operation.
In this article readers will find a technical overview of the 318601500 module including its primary functions, compatibility considerations, common failure symptoms and diagnostic clues, basic troubleshooting checks technicians can perform safely (visual inspection, connector verification, sensor resistance checks and output switching verification), and practical replacement considerations such as confirming part number and connector compatibility, addressing ESD and mains safety, and verifying oven calibration after replacement. The content is intended to help technicians, engineers and appliance owners understand how the control behaves in service and what evidence to gather before deciding on repair or replacement.

Functional role and system interfaces of the oven control module in frigidaire electric ranges
The control board designated 318601500 Frigidaire Oven Control is the centralized electronic module that sequences oven functions,enforces safety interlocks,and executes temperature regulation algorithms. Functionally, the board reads temperature inputs (thermistor or probe), accepts user commands from the keypad assembly, and drives high‑voltage switching elements (relays or triacs) to energize bake, broil, and convection elements. The module also supervises ancillary loads such as the convection fan and oven light, monitors the door lock during self‑clean cycles, and reports fault conditions to the user interface; in many designs it implements closed‑loop temperature control (on/off or PID style duty cycles) to maintain setpoint accuracy under varying thermal loads.
- Line‑voltage outputs for bake/broil/convection element control (relays/triacs)
- Low‑voltage interface to keypad, display, and indicator LEDs
- Sensor inputs: oven thermistor and optional probe; door/lock position switches
- Auxiliary outputs: cooling fan, oven light, and door lock actuator
- Diagnostics and fault reporting via status LEDs or encoded display messages
| Item | Description |
|---|---|
| Element output | Line‑voltage switching circuits (relays/triacs) that supply bake, broil, and convection heating elements |
| Thermistor input | Low‑voltage analog input from the oven temperature sensor used for closed‑loop control and safety limits |
| User interface | Ribbon or keyed connector carrying keypad switches, display segments, and status indicators |
Compatibility and practical serviceability depend on connector pinout, mounting geometry, and firmware variants; technicians shoudl verify harness compatibility and harness color coding before installation rather than assuming interchangeability. In troubleshooting scenarios the board can be isolated by checking continuity of element circuits and verifying expected voltage at relay outputs with the cabinet powered and calling for heat, and by measuring the resistance curve of the thermistor at ambient and elevated temperatures. When replacing the control with a 318601500 unit,confirm identical connector layouts and test basic functions (display,key response,element switching,and sensor reading) during initial power‑up after reconnecting power and before final assembly.
How the 318601500 Frigidaire Oven Control processes sensor inputs, timers, and power outputs inside the appliance
The 318601500 frigidaire Oven Control acts as the appliance’s central manager for thermals, timers, user commands, and power distribution. it accepts inputs from the oven temperature sensor (thermistor or RTD), door and latch switches, user interface switches, and line-voltage sense circuits; these analog and digital signals are sampled by on-board ADCs and logic so the control can make real-time decisions. When a temperature input deviates from expected resistance ranges the control’s firmware will flag a sensor fault and inhibit element outputs or display an error, and during normal operation it converts the temperature feedback into a heating demand signal used to modulate element power. Compatibility depends on matching connector pinouts, sensor type and resistance range, and the board’s rated switching devices – replacing the board requires verifying that the replacement supports the same sensor characteristics and mains load handling as the original unit.
Timers and power outputs are managed by deterministic firmware routines that implement preheat cycles, timed cook functions, and safety interlocks. The control uses short-duration timing (for element duty cycles) and longer count-down timers (for cook duration and delayed starts) and converts heating demand into element drive signals via relays or solid-state switching devices depending on the model; many circuits use closed-loop control with hysteresis or proportional duty control to reduce overshoot. For practical troubleshooting or integration, check the sensor resistance behaviour while heating, verify that the control’s output relays or triacs receive mains and switch under command, and ensure the replacement board’s output ratings match the oven’s element current and voltage specifications.
- Key checks: validate sensor resistance change, confirm line voltage at input terminals, observe relay/SSR actuation while commanding heat, and verify connector pinout match for replacement boards.
| Item | Description |
|---|---|
| Temperature input | Thermistor/RTD resistance signal sampled by ADC for closed-loop temperature control |
| Timers | Firmware timers for preheat, cook duration, and delayed start; separate PWM/timing for element duty cycles |
| Power outputs | Relays or solid-state switches rated for oven element current; controlled according to temperature demand and safety interlocks |
Common failure symptoms and diagnostic indicators for oven control faults
The oven control board coordinates user input, timing, and power switching to the bake and broil elements; models that use the 318601500 Frigidaire Oven Control integrate display, relay/triac drivers, sensor input, and safety interlocks on a single PCB. Typical control-board failures present as electrical and functional anomalies rather than purely cosmetic faults: persistent error codes or a blank display, failure to energize the bake or broil circuits despite correct user settings, intermittent operation where the element cycles on and off unpredictably, or unresponsive front-panel controls. Technicians should separate control-board malfunction from downstream causes by confirming line voltage at the incoming terminals and checking the oven temperature sensor and element continuity before attributing symptoms to the control module itself.
- Blank or garbled display, or persistent F‑codes indicating control errors
- Elements receive no voltage when a heat mode is selected (no heat)
- Intermittent heating or rapid cycling indicating relay/triac failure
- Touchpad or knobs unresponsive while othre functions work
- Visible damage: burned traces, charred connectors, or swollen capacitors
Practical diagnostics start with power and harness verification: measure mains presence at the controlS input, then command a heat mode and measure the output terminals for the expected line voltage; absence of output with correct input points to the control as the fault, whereas correct output with no element heat suggests element or wiring faults. Check the oven temperature sensor resistance (many Frigidaire sensors read roughly 1 kΩ at room temperature) and inspect for cold solder joints or cracked solder pads on the control board; replace the control only after confirming harness pinout and mounting compatibility with the appliance model, as substitutions require identical terminal assignments and mounting to avoid miswiring. the table below summarizes common symptom-to-cause mappings and the fast checks a technician can perform on site.
| Item | Description |
|---|---|
| No heat with correct display | Control failed to drive element; verify mains in, then measure voltage on bake/broil outputs when commanded |
| Intermittent heating or clicking | Relay/triac driver degradation or loose connector; inspect solder joints and test outputs under load |
| Blank display or error codes | Power supply or microcontroller fault on board; check incoming voltage and look for blown components |
Compatibility, replacement considerations, and step‑by‑step installation procedures for affected Frigidaire models
The 318601500 Frigidaire Oven Control is a microcontroller-based control module that coordinates key oven functions: user interface, bake/broil element switching, sensor monitoring, and safety interlocks.Its outputs typically drive relays or triacs to switch mains power to heating elements while logic-level circuits handle the display and keypad. Troubleshooting compatibility requires inspection of the board part number, connector harness arrangement, and any inline fuses or thermal cutouts; physically similar boards can differ in connector pinouts or firmware, causing incorrect behavior if swapped without verification. Technicians should verify the harness pinout and the oven temperature sensor resistance against the service manual before installation to confirm electrical compatibility rather than relying solely on chassis fitment.
Installation for affected Frigidaire models follows standard appliance-control procedures: remove all power,document and photograph existing wiring and connector orientations,and observe ESD precautions when handling the replacement board.Installers should transfer any user interface membranes, thermistor leads, and retainers, inspect board-mounted fuses and solder joints for damage, and secure the module to the chassis with the original hardware to maintain grounding. after reassembly,perform a controlled power-up and run the oven’s self-test or diagnostic mode to confirm keypad response,display operation,proper switching of bake/broil elements,and correct sensor readings; if error codes appear,consult the model-specific service chart before further disassembly.
- Disconnect power and verify zero voltage at the control harness.
- Label and photograph connectors; transfer harnesses exactly as found.
- Observe ESD control (ground strap or touch metal) and avoid flexing ribbon cables.
- Inspect and, if blown, replace on-board fuses and check for burned traces.
- Perform diagnostic/self-test and verify element activation and sensor resistance.

Q&A
What is part number 318601500 for a Frigidaire oven and which models use it?
Part 318601500 is an electronic oven control/clock assembly used on a range of Frigidaire ovens and some Electrolux/GLS-built models.It provides the user interface, timer/clock functions and controls oven relays for bake/broil. Compatibility depends on the specific oven model and production date, so always check the appliance model/serial tag and the parts diagram or retailer listing to confirm fit.
What symptoms indicate the 318601500 oven control might be failing?
Common symptoms include an unresponsive or blank display, touchpad/buttons not working, oven not heating though broiler or elements show activity, erratic operation (random cycles or beeps), or persistent error codes related to control or dialog. Intermittent faults that clear after power-cycling can also point to a failing control board.
How can I diagnose whether the problem is the control board or another component (like the temperature sensor)?
Start by recording any displayed error codes and consult the oven’s tech sheet/service manual. Check obvious items first: ensure the oven has proper power and that fuses/circuit breakers are OK. For temperature issues, measure the oven temperature sensor resistance at room temperature with a multimeter – typical oven sensors are roughly ~1,000-1,200 ohms at room temp (consult your model’s spec). If the sensor reads open or far outside expected range,replace the sensor. If the sensor and power are good but the control is unresponsive or shows unrelated errors, the control board is more likely at fault.
Can I replace the 318601500 control myself, and are there any special tools required?
Many technicians and handy owners can replace the control board. Basic tools (screwdrivers, nut drivers) and a multimeter for verification are usually sufficient. Always disconnect power at the breaker before starting. The job typically involves removing the console panel, disconnecting wire harnesses, and swapping the boards. If you’re uncomfortable working with live circuits or removing panels, hire an appliance technician.
After installing a new 318601500 control, does it need to be programmed or reset?
In most cases a control will power up with default settings once installed. Perform a power cycle (disconnect power for 30-60 seconds and restore) to ensure a proper reset. Some models require setting the clock or entering basic configuration options (temperature units, child lock, etc.) via the control panel. If your oven has a service/program mode for calibration or options, consult the service manual for model-specific steps.
Are there common error codes associated with this control and what should I do when one appears?
Different Frigidaire models show varying error codes; common categories include sensor/temperature errors, keypad faults, and communication or relay failures. When an error appears, write down the exact code, power-cycle the oven to see if it clears, then consult the owner’s manual or service sheet for that code’s meaning. If the code indicates a sensor fault,measure the oven sensor resistance; if it indicates keypad/control faults,the control assembly may need repair or replacement.
What safety precautions should I take when handling or replacing the oven control board?
Always disconnect power at the household breaker before touching internal components. Avoid working on a hot appliance. Use anti-static precautions if possible (discharge yourself by touching grounded metal) and avoid touching circuit traces or solder joints. Keep liquids away from electronic parts and secure all wire harnesses and screws when reassembling. If the unit has capacitor-containing power supplies, allow time for them to discharge or consult a technician.
Where is the best place to buy a replacement 318601500, and how do I ensure I get a genuine part?
Buy from Frigidaire’s official parts site, authorized dealers, or reputable appliance parts retailers (online or local). Verify the part number against your oven’s parts diagram and the appliance model number. Check return policies and warranty; genuine OEM parts will frequently enough have a manufacturer warranty and proper fit/connector layouts,which reduce the risk of incompatibility versus generic or aftermarket substitutes.
