318601500 Frigidaire Oven control is an electronic control module used too manage oven functions on compatible Frigidaire ranges and wall ovens. It is a printed circuit board assembly that typically incorporates the user interface logic, timing and sequencing circuitry, power switching elements (relays or triacs) and the connectors required to interface with the appliance wiring harness; in service and parts literature it is commonly referred to as the oven control or main control board.
Inside the appliance the control performs central coordination: it accepts user inputs from the keypad or touchpad, displays status details, reads temperature feedback from the oven temperature sensor, and drives outputs that energize bake and broil elements (or gas valves), convection fans, interior lights and other subsystems. Technically, the board contains low-voltage control electronics, power conversion and switching components, and diagnostic firmware; it therefore interfaces with the line-voltage supply, temperature sensors (thermistors/rtds), door and safety interlocks, and the heater/circulator circuits. Understanding those interfaces and the control’s role in sequencing and safety interlocks helps technicians and engineers isolate electrical, sensor or software-related faults more efficiently.
In this article readers will learn how the 318601500 oven control is designed to function, wich models and control variants it is compatible with, common failure symptoms (such as no heat, incorrect temperature regulation, non-responsive controls or error codes), and a structured approach to troubleshooting such failures. The article will also cover practical replacement considerations – matching part numbers and wiring harnesses, basic pre- and post-installation checks, and safety precautions when working with line-voltage appliances – so appliance owners and service technicians can make informed diagnostic and repair decisions.

Functional Role and Electrical Interfaces of the Oven control Module
the 318601500 Frigidaire Oven Control is the main electronic module that coordinates user commands,timing,temperature regulation,and safety interlocks on compatible Frigidaire ranges. It accepts inputs from the keypad/knobs and the temperature sensor, implements control logic to reach and maintain set temperatures, and sequences outputs such as the bake and broil circuits, convection fan, oven light, and door lock. When replacing this part, verify the harness pinout and physical connector shape; identical-looking boards may have different firmware or connector assignments and can power up without correctly controlling the oven if not fully compatible.
- Line-voltage inputs for element power and relay/triac switching
- Low-voltage DC supply and logic domain for microcontroller and display
- sensor inputs (thermistor/RTD) for temperature feedback
- Switched outputs to bake, broil, convection fan, and oven light
- User-interface and diagnostic/communication lines (display, LEDs, serial)
Electrically, the module separates high-power switching and low-voltage control: high-current feeds for the heating elements are routed through relays or triacs driven by the board, while the microcontroller and display run from a regulated low-voltage supply. In troubleshooting, check for presence of the control supply, verify sensor resistance at ambient and compare to expected values, and confirm that the board is commanding the high-voltage outputs – for example, measure 120 VAC at the bake output connector when the oven is calling for heat. practical service steps include checking connector pinouts against the oven wiring diagram, measuring voltages with the oven in the appropriate mode, and inspecting grounding and harness continuity; mismatched boards often exhibit correct display behavior but fail to energize the correct element circuits.

| Switched outputs | Relays or triacs for bake, broil, convection fan, light, and door lock |
| Diagnostics | Display drivers, status LEDs, and sometimes serial/diagnostic communication lines |
how the 318601500 Frigidaire Oven Control Works: Circuit Architecture, Firmware Logic, and Signal Flow
The 318601500 Frigidaire Oven Control is a compact PCB assembly that integrates a microcontroller, power regulation, user interface drivers, temperature-sensor inputs, and the switching stage for the oven elements. On the hardware side you will typically find a low-voltage supply for logic and display, a dedicated thermistor or RTD input with conditioning resistor network, and discrete outputs implemented as triacs or relays that switch the bake/broil elements and the convection fan. Functionally the board acts as the central coordinator: it translates keypad commands into setpoints, monitors sensor feedback and safety interlocks, and energizes the appropriate outputs while providing diagnostic feedback to the user. Compatibility depends on connector pinout and harness orientation rather than just the board form factor, so technicians must verify pin assignments and mounting features before swapping controls between model variants.
The firmware implements the control and safety logic that governs signal flow across the assembly: input processing reads the keypad and door switches, the temperature sensor routine measures oven temperature and filters noise, and the control algorithm modulates power to the heating elements via phase-angle or time-proportional switching to maintain setpoint.The code also handles timers, preheat sequencing, lockout states, and fault detection routines that flag sensor open/short, element failures, and communication errors; when a fault is detected the firmware will disable outputs and set an error code on the display. Signal flow is thus deterministic-user command → MCU processing → control decision → power-driver activation → sensor feedback-allowing service technicians to trace failures by checking connector voltages, continuity of heaters and sensors, and observing displayed error codes or LED diagnostics.
- Key signal paths: user input to MCU, thermistor input to ADC, MCU output to triac/relay drivers, safety interlock inputs (door, high-limit).
- Common behaviors: duty-cycled element control for temperature hold,time-based preheat,and locked-down modes for child safety.
- troubleshooting hints: confirm harness pinout, measure DC supply rails, read sensor resistance at room temperature, and observe whether outputs are switching under commanded conditions.
| Item | Description |

| Microcontroller | Runs firmware, reads inputs, executes control algorithm, updates display. |
| Temperature sensor input | Thermistor/RTD interface providing oven temperature for closed-loop control. |
| Power outputs | Triacs or relays that switch bake/broil elements and fans; controlled by MCU drivers. |
| Connectors & diagnostics | Pinouts for harness, status LEDs or error codes used for service diagnostics. |
Common Failure Symptoms, Error Codes and Diagnostic Indicators for Oven Control Malfunctions
The 318601500 Frigidaire Oven Control typically presents failures through a set of reproducible symptoms that reflect either user-interface faults, sensor feedback problems, or power/output stage failures. Technicians will commonly encounter a blank or unresponsive display, intermittent relay clicking with no element activity, inaccurate oven temperatures, and the appearance of diagnostic codes on the display. These behaviors can result from failed components on the control board (drivers, triacs, relays), degraded solder joints, corroded harness connections, or upstream electrical issues; some faults that appear as control failures are actually caused by a defective oven sensor or wiring harness rather than the control module itself.
- Blank or garbled display / unresponsive keypad
- Oven does not heat or heats continuously
- Temperature offset or fluctuation during cooking cycles
- Intermittent operation or relay/coincident clicking
- Specific error codes shown on display indicating sensor, communication, or control faults
- Visible signs: burnt traces, discoloration, or corrosion at connectors
| Item | Description |
|---|---|
| UI/Keypad | Display blank, stuck keys or erratic inputs; often caused by keypad failure, shorted traces, or front panel connector faults |
| Sensor feedback | Error codes related to temperature sensing; usually points to an open/short thermistor, poor connector pin contact, or intermittent wiring |
| Output stage | No heat or constant heat indicates failed relays/triacs, driver circuits, or interrupted mains supply to the board |
For practical diagnostics, verify incoming line voltages and measure the oven temperature sensor resistance against the manufacturer specification before condemning the control. Inspect connectors and harnesses for heat damage, and visually examine the board for cracked solder joints or burned components; intermittent faults commonly correlate with mechanical stress fractures on solder pads. Use the oven’s built-in diagnostics (if available) to capture stored fault codes, then correlate those codes with sensor readings and output voltage checks – for example, if a sensor-related code is present and the thermistor measures open or out-of-range resistance, replace the sensor or repair the harness prior to replacing the control module. When replacing the board, confirm compatibility with the model and document any recurring patterns (specific codes, timing of failures, or environmental factors) that could indicate a systemic wiring or installation issue rather than an isolated control failure.
Compatibility, Replacement Considerations and Step-by-Step Installation Procedures for the Oven Control
The 318601500 Frigidaire Oven Control is an integrated user interface and control module that manages timer functions, temperature regulation, and power switching for bake and broil circuits. Internally it typically contains a microcontroller, solid-state or relay outputs for line-voltage elements, and analog/digital inputs for the oven thermistor and door-switch sensors. compatibility depends on the board harness, connector pinout, and chassis mounting – functionally identical assemblies must match the oven’s molex connector layout, control logic voltage levels (logic supply vs. mains switching), and display/keyboard interface. In practice, technicians verify the part number against the oven’s service manual and compare the harness pinout and mounting geometry rather than relying solely on model-year similarity, because cosmetic or firmware differences can prevent a drop-in replacement from operating correctly.
Replacement and installation require both electrical verification and procedural care: disconnect mains power, label harness connectors, confirm that the replacement 318601500 Frigidaire Oven Control has the same connector pin assignments and element switching ratings, and inspect the thermistor and relay contacts before reassembly. A typical installation sequence is the following, each step intended to reduce risk of miswiring or damage to control electronics.
- Power off: Cut mains power at the breaker and verify with a multimeter.
- Remove access panel and photograph existing wiring and control orientation.
- Disconnect and label each harness; compare pin-to-pin against the replacement control.
- Transfer mounting hardware and secure the new control; avoid over-torquing plastic standoffs.
- Reconnect harnesses in the documented order and restore power briefly to check display/LED diagnostics before final reassembly.
- Perform a bake and broil functional test with a temperature probe to confirm proper regulation and no unexpected element energization.

Q&A
What is part 318601500 and which Frigidaire ovens does it fit?
Part 318601500 is the electronic oven control / clock-timer assembly used on a range of Frigidaire (and some Kenmore/related brand) electric ovens and ranges. It controls the display, keypad, bake/broil cycles and oven functions.It does not fit every Frigidaire model – you must verify compatibility by matching the part number to your oven model number (usually on a tag inside the oven door frame or on the back of the range) or by using an OEM parts cross-reference. Physical appearance, connector locations and mounting holes should match exactly.
What are common symptoms that the 318601500 control is failing?
Common signs include a blank or garbled display,unresponsive or stuck keypad,oven not heating or not turning elements on while the display indicates it should,intermittent operation,random starts/stops,persistent error codes,and incorrect oven temperature readings. Visible burn marks, cracked solder joints or a burnt smell behind the control are also indicators of control-board failure.
How can I diagnose whether the control board (318601500) is bad?
Diagnose in stages: first verify basic power (breaker on, main fuses intact). Check for visible damage on the board (burns, bulging capacitors).Use a multimeter to confirm supply voltage is reaching the control and to check continuity of fuses and heating elements. Measure the oven temperature sensor resistance (many Frigidaire oven sensors are roughly ~1000-1150 ohms at room temperature – consult your model spec). Review any displayed error codes and compare to the service manual. If the sensor and elements are good and power reaches the board but outputs don’t switch when commanded, the control is likely defective. Because mains voltages are involved, consider having a qualified technician complete electrical checks.
Can I replace the 318601500 myself, and what precautions should I take?
Yes, a competent DIYer can replace it, but you must take safety precautions. Disconnect power at the breaker (do not rely on turning the oven off) and confirm no voltage present. Remove the console or back panel per your model’s service instructions, photograph wiring and connector locations for reassembly, and carefully unplug ribbon and wire connectors.Avoid touching circuitry and discharge any large capacitors if present. Use insulated tools and reassemble securely. If you are uncomfortable working with live circuits or the replacement requires structural disassembly, hire a qualified appliance technician.
Does a replacement 318601500 need programming or special configuration after installation?
Most Frigidaire control modules are direct replacements and require no special programming – the board will accept the oven’s basic settings once installed. After replacement you will typically need to set the clock, run a self-test or diagnostics (if available), and recalibrate the oven temperature if necessary.Check the service/installation sheet for your model; a few units may retain model-specific configuration on the old board, but this is uncommon.
How do I calibrate oven temperature after replacing the control?
Use an accurate oven thermometer placed in the center of the oven. Preheat to a known temperature (for example 350°F). Compare the thermometer reading to the set temperature. If the oven is consistently off by a fixed amount, use the oven temperature adjustment or calibration feature in your owner’s manual to add/subtract degrees (many Frigidaire models allow ± adjustments in 1°F or 5°F increments). Re-test until readings match within an acceptable tolerance. If temperature swings wildly rather than being offset, check the sensor, element and door seal rather than the control.
Where should I buy a genuine 318601500 and what does it typically cost?
Buy from authorized Frigidaire dealers, official parts distributors, or reputable appliance-parts retailers to ensure an OEM part and warranty. Prices vary by supplier and region; expect an OEM control board to commonly range from about $100 to $300 USD. Avoid very cheap unbranded boards without return/exchange policies – they may be unreliable or incompatible. Always verify compatibility with your oven model before purchase.
