318601500 Frigidaire Oven Control is an electronic control module used in Frigidaire ovens; it is a microprocessor-based control board that manages user interface functions, timing and sequencing, and the switching of heating and safety circuits. As a central control component, the module typically includes the display and keypad interface, relay or solid-state drivers for bake/broil elements or igniters, and connections for temperature sensors and auxiliary devices.
Inside an appliance system the control acts as the coordination point between user inputs and the oven’s mechanical and thermal systems. it receives signals from the touchpad or knobs, interprets mode and temperature settings, monitors feedback from the oven temperature sensor (thermistor or RTD), and actuates relays or triacs to supply power to elements, igniters or fans. The board also interfaces with door lock mechanisms, timers and safety interlocks, and in some models communicates with other modules; as it controls both user commands and power switching, it is indeed typically used in Frigidaire electric and dual-fuel ranges and built-in ovens and is essential for correct operation and safety of the appliance.
In this article readers will find a technical overview of the 318601500 control’s functional role and typical architecture, guidance on model compatibility and identifying equivalent part numbers, common failure symptoms to look for (unresponsive controls, no display, oven not heating or overheating, erratic cycling, or persistent error codes), basic diagnostic approaches for technicians (visual inspection, connector and wiring checks, sensor verification and output voltage measurements), and practical replacement considerations such as matching harnesses and connectors, necessary safety precautions, and post-replacement checks to verify correct operation.

Functional Role, Power Requirements, and Control Interfaces of the Oven Control Module
The 318601500 Frigidaire oven Control is the central electronic module that sequences oven functions: it reads temperature sensors, interprets user setpoints from the keypad or touch interface, executes the control algorithm to regulate bake and broil elements, and enforces safety interlocks (thermal fuses, door switches). The board receives the appliance’s line power and provides switched AC outputs to heating elements via relays or triacs while also hosting a low-voltage regulated supply for the display and microcontroller. In practice this part implements a closed-loop temperature control (commonly PID or on/off with hysteresis) and stores user settings and diagnostic codes in nonvolatile memory, so replacement units must match the original harness and electrical ratings to ensure proper behavior and compatibility with the oven chassis and wiring harness.
Technicians should view the control as both a logic and power-handling device: the logic section manages timing,menus,and diagnostic reporting,while the power stage switches high-current AC to elements and safety devices. Typical failures manifest as unresponsive keypads, no element switching despite correct setpoints, or erratic temperature readings; troubleshooting examples include measuring the relay/triac output at the terminal block during a heat call, checking thermistor resistance at ambient against the service chart, and verifying continuity of thermal cutouts. Replacement considerations include ensuring matching connector pinouts, verifying the oven’s nominal supply (single- or double-line) and confirming that any model-specific configurations or calibration steps are followed after installation.
- User interface inputs: keypad, touchpad, or selector switches
- Sensor inputs: thermistor/RTD temperature input and oven door/door latch switches
- Power outputs: relay/triac-switched AC to bake, broil, convection fan, and broiler igniter circuits
- Diagnostics and memory: fault code reporting, status LEDs, and nonvolatile settings storage

How the 318601500 Frigidaire Oven Control Processes Inputs, Manages Relays, and Interfaces with Temperature Sensors
The 318601500 Frigidaire Oven Control handles operator commands and sensor feedback with a microcontroller that scans the keypad matrix, debounces digital inputs, and samples analog sensors through an ADC. User selections, clock/timer signals, and safety interlocks are read as discrete or matrixed inputs; the oven temperature input – typically a thermistor – is measured as a resistance value, converted to temperature, and validated against expected ranges. Measured temperature and setpoint are passed to the control loop so the controller can determine heating demand, detect open/short sensor conditions, and flag faults if the sensor reading deviates beyond configured thresholds or if expected element current/voltage is absent.
output management is done by driver stages that command line-voltage switching devices (mechanical relays or solid-state drivers) to energize the bake, broil, convection, and cooling circuits. The control enforces sequencing and interlocks (for example, preventing bake and broil from switching on concurrently, applying soft-start or minimum off-time to protect relays, and inhibiting element power during door-open conditions). In normal operation the control modulates power via time-proportional cycles or closed-loop PID/hysteresis behavior to maintain setpoint; practical troubleshooting frequently enough uses the control’s response to a simulated sensor (substitute resistor) and observation of relay chatter or fault codes to verify correct interface and timing.
- Keypad and touch inputs (matrix scanned, debounced)
- Oven temperature sensor (thermistor/RTD analog input)
- Line-voltage sense, door and safety interlocks (discrete inputs)

| Temperature input | Analog thermistor voltage converted to temperature; used in PID/hysteresis loop and fault detection |
| Relay outputs | Driver stage controls line voltage to bake/broil/convect elements with enforced sequencing and minimum on/off times |
Diagnostic Symptoms and Common Failure Modes: Temperature Deviations, Relay Sticking, and Display/Keypad Errors
The 318601500 Frigidaire Oven Control is the primary electronic module that monitors oven temperature, commands the bake/broil outputs, and interprets user inputs. It reads the oven temperature via the temperature sensor (NTC thermistor), drives mechanical relays or solid-state switching elements to energize heating circuits, and processes keypad/display activity. When the control or related wiring fails, technicians commonly observe temperature deviations such as overshoot, long recovery times, or inability to hold setpoint; these behaviors can result from a damaged thermistor, intermittent harness connections, incorrect calibration, or welded relay contacts that prevent the element from cycling correctly.
- Temperature swings or inaccurate temperature relative to setpoint
- Continuous heating or failure to energize elements (stuck relay)
- Intermittent operation, random resets, or oven shutting down mid-cycle
- Unresponsive keypad, scrambled display segments, or persistent error codes
Relay sticking typically presents as a heating element that remains energized regardless of commanded state; this is usually caused by contact welding, failed relay drivers on the control board, or a short in the wiring harness. To isolate the fault, check for continuity and visible contact damage at the relay, verify the control’s drive signal with a multimeter or oscilloscope, and inspect connectors for corrosion. Display and keypad errors more often trace to ribbon cable failures, moisture ingress at the overlay, or failed display driver components on the board; swapping the user interface assembly (if compatible) or reseating the ribbon can confirm whether the fault is in the interface or the 318601500 Frigidaire Oven Control itself.
| Item | Description |
|---|---|
| Temperature deviation | Often caused by a faulty thermistor, loose harness, or incorrect calibration; verify sensor resistance curve and control temperature PID behavior. |
| Relay sticking | Welded or mechanically failed relay contacts or failed relay driver; symptoms include continuous element power or no cycling. |
| Display/keypad errors | Ribbon cable, connector corrosion, or display driver faults on the control board; symptoms include unresponsive keys or garbled readout. |
Compatibility, Replacement Considerations, Installation Sequence, and Troubleshooting Procedures for Service Technicians
The 318601500 Frigidaire Oven Control is the primary control board responsible for user interface, temperature regulation, and switching the oven’s heating circuits. Technicians must confirm compatibility by matching the printed part number, connector pinout, and mounting footprint to the oven model and serial; visually similar boards can have different relay/triac ratings or sensor input scaling. Replacement considerations include transferring thermistor/temperature-sensing hardware and door interlocks to preserve calibration, and verifying that the harness harness locking tabs and EMI filters line up with the chassis openings. Such as, two ranges within the same family may use identical front panels but different power relay ratings-installing a lower-rated board can produce overheating or premature failure.
- Common symptoms to verify before replacement: blank or flickering display, unresponsive keypad, oven fails to heat while elements show continuity, persistent error codes, or visible burnt components on the board.
- Pre-replacement checks: confirm mains voltage at the junction, photograph connector positions, label harnesses, and check thermistor resistance against the service specification.
Follow a controlled installation sequence and structured troubleshooting: disconnect mains power,remove the access panel,document harness positions,and transfer sensors and terminal blocks as needed. After reassembly,restore power and perform diagnostic tests-verify incoming line voltage at the board,measure the board’s element output terminals under a bake cycle,and read thermistor resistance to confirm proper temperature feedback. If heating is absent but the control is commanding heat,test relay or triac output for switching and inspect for cold solder joints or blown surface-mount components; if the display is dead yet control logic is active,check the display ribbon and related power rails. Clear stored diagnostics, run a self-test or a controlled bake at a moderate setpoint, and confirm stable control cycling and correct temperature ramp as the final verification.
| Item | Description |
|---|---|
| Part verification | Match printed 318601500 marking, harness pinout, and relay/triac ratings to service manual before installation. |
| Diagnostic checks | Measure incoming L/N,check element outputs for switched voltage,and verify thermistor resistance per spec. |
| Installation note | Transfer sensors and secure mounting; ensure harness locking tabs engage to prevent intermittent faults. |
Q&A
What is part number 318601500 for Frigidaire ovens?
Part 318601500 is an electronic oven control (the main user/display/control board assembly) used on certain Frigidaire/Frigidaire-affiliated electric oven and range models. It manages the front display, user keypad, temperature control, timers and the switching logic that tells bake/broil circuits and relays when to apply power. always confirm compatibility with your exact appliance model number before purchasing.
What are common symptoms that the 318601500 oven control is failing?
Common signs include a blank or garbled display, unresponsive touchpad/keys, oven functions that won’t start or stop, incorrect temperature regulation, frequent unexplained error codes, or visible damage on the board (burn marks, blown components). Note that many symptoms can be caused by wiring, fuses, the oven sensor, or the power supply – so the control board isn’t always the root cause.
How can I diagnose whether the control board (318601500) is bad or something else is at fault?
start with these steps: 1) Disconnect power and visually inspect the board and connectors for burns, corrosion or loose pins. 2) Verify incoming line voltage at the range (with power on, use caution) and check house breakers. 3) Check the oven sensor (temperature probe) resistance with a multimeter - it’s typically around 1,000-1,200 ohms at room temperature; a large deviation suggests a bad sensor. 4) Check any thermal fuses or cutoff thermostats for continuity. 5) Swap or test the keypad ribbon/cable connection. If all external components and supply are correct and the board still behaves erratically (or shows damaged components), the control board is highly likely defective. If you’re not agreeable with high-voltage tests,have a qualified technician perform them.
How do I safely replace the 318601500 oven control?
Basic replacement steps: 1) Turn off power at the breaker and verify power is off. 2) Remove oven parts as required to access the control (lower access panel or control panel). 3) Photograph wiring and label connectors so you can reconnect them correctly. 4) Disconnect ribbon cables and harness connectors,remove mounting screws,and transfer any bezels or mounting hardware to the new control. 5) Install the new board, reconnect connectors, and reassemble. 6) Restore power and test all functions. Important safety notes: always cut power first, avoid touching circuitry with static-prone clothing (discharge yourself), and if you are not experienced with electrical appliances, hire a technician.
How can I tell if a display/keypad issue is caused by the board 318601500 or just the keypad?
Keypad issues caused by the user interface or membrane often manifest as unresponsive or stuck keys while other oven functions controlled by the board still operate. If the display is visible and the oven can start using timed or knob-based functions while some keys don’t respond, the keypad assembly might potentially be the culprit. If the display is blank, erratic, or all functions fail, that points more strongly to the electronic control. You can also check the keypad ribbon cable for damage and reseat it - if reseating or replacing the ribbon fixes it,the board may be fine.
Are there specific error codes related to the oven control 318601500 and what do they mean?
Frigidaire ovens use fault or “F” codes to indicate problems; codes can indicate keypad faults, temperature sensor failures, relay/triac faults, or interaction errors between modules. Exact meanings vary by model. If you see an F/P code, note the full code and consult the model’s service manual for the code list and troubleshooting procedures. Many codes should prompt checking the sensor, wiring, and board connections before replacing the control.
Will replacing the oven control 318601500 fix temperature accuracy problems?
Not always. Temperature accuracy is commonly caused by a failing oven temperature sensor (probe) or incorrect sensor resistance, poor wiring connections, or door seal/insulation issues.The control board regulates power based on the sensor input; if the sensor gives wrong readings, the control will behave incorrectly even if it’s functioning. Replace or test the sensor first (measure resistance at room temperature - about 1,000-1,200 ohms). Replace the control only if diagnostics point to the board itself.
How do I confirm that 318601500 is the correct replacement part for my Frigidaire oven?
Do not rely solely on the appliance’s model name. Locate and record your full appliance model and serial number (usually on a tag inside the oven frame, behind the door, or on the back of the range). Use those numbers with the manufacturer’s parts lookup, the Frigidaire parts website, or a reputable parts dealer to confirm compatibility. Cross-reference part numbers and any sub-model variations; some boards are visually similar but have different connectors or firmware and will not work interchangeably.
