318601500 Frigidaire Oven Control is an electronic control module used to manage oven functions in Frigidaire electric ranges adn built‑in ovens. It is indeed a printed circuit board assembly that typically contains teh user interface circuitry, display drivers, microcontroller or microprocessor, power regulation components, and output switching devices (relays, triacs or solid‑state relays) that directly control heating elements and timers.
Inside the appliance the control acts as the central logic and timing unit: it receives input from the keypad or touchpad and temperature sensors (thermistors or RTDs), applies control algorithms, and then energizes the appropriate outputs for bake, broil, convection, timers, and safety interlocks. The board interfaces with the line voltage supply and with subsystem components such as the oven light, door latch (on self‑cleaning models), cooling fans, and any gas ignition circuitry on compatible models. Proper operation of the control is therefore essential for regulated temperature control,sequencing of heating cycles,and coordination of user commands with safety and diagnostic functions.
In this article you will find a technical overview of the 318601500 Frigidaire Oven Control covering its functional role, typical compatibility and connector details, common failure symptoms (for example no heat, continuous heating, unresponsive controls, or display/error codes), and step‑by‑step troubleshooting procedures suitable for technicians and knowledgeable appliance owners. The guide also discusses diagnostic checks (visual inspection,voltage and continuity measurements,sensor verification),safety precautions for working with mains voltage and stored energy on the board,and practical considerations for replacement such as verifying part numbers,connector pinouts,and post‑installation verification and calibration.

function and Role of the oven Control Module in Frigidaire Electric Ranges
The 318601500 Frigidaire Oven Control is the main electronic control module that coordinates user inputs, timing functions, and closed‑loop temperature regulation for the oven. It monitors the oven’s temperature sensor, interprets keypad and timer commands, and energizes the bake, broil and convection outputs through relays or solid‑state switching devices. The module also enforces safety interlocks (door lock, high‑limit) and manages auxiliary functions such as the convection fan and timed cycles. When assessing functionality, technicians should verify connector pinouts, line voltage to the board, and sensor feedback before replacing the control to avoid misdiagnosis of common wiring or sensor issues.
- Key symptoms of control failure: unresponsive keypad/display, heating elements not energizing, erratic temperature control, or persistent error codes.
| Item | Description |
|---|---|
| Inputs | Temperature sensor, keypad/display signals, line voltage, door/limit switches |
| Outputs | Bake/broil relay or triac lines, convection fan control, status indicators |
| Diagnostic checks | Verify sensor voltage/resistance per spec, confirm mains present at board, test switched output continuity with demand |
For compatibility and repair decisions, match the part number and harness configuration rather than relying solely on visual similarity; the 318601500 Frigidaire Oven control must be compatible with the oven model’s connector layout and feature set. In practice, a methodical diagnostic approach-checking incoming mains, measuring sensor feedback, observing relay/triac activation under commanded cycles, and reviewing fault codes-will distinguish between a failed control module and upstream components like a shorted element or open sensor.Replacing the board without these checks can leave the original fault unresolved or introduce needless expense.
How the 318601500 Frigidaire Oven Control Interfaces with Sensors, Relays, Power Supplies and User Inputs
The 318601500 Frigidaire Oven Control acts as the central control node between temperature sensors, line‑voltage switching elements, the control power supply and the user interface. it accepts low‑level analog inputs from the oven temperature sensor (typically an NTC thermistor or similar),interprets the temperature via an internal ADC and temperature lookup or compensation algorithm,and issues timed control commands to relays or solid‑state switching devices that feed the bake/broil elements. User inputs (membrane keypad, rotary encoder or touchpad) are read on dedicated input lines or a scanned matrix and are debounced and authenticated by the control firmware before changing setpoints or state; status and fault information are routed to the display and to diagnostic outputs for service access.
Electrically, the board separates the low‑voltage logic domain from high‑voltage switching using opto‑isolators, driver transistors or relay coils and appropriate snubbing to protect semiconductor outputs from inductive transients. the onboard power supply converts incoming mains to regulated DC rails required by the microcontroller and display, and typically includes thermal or fuse protection and a standby input for clock/timekeeping.For practical troubleshooting and compatibility assessment, technicians should verify connector pinouts, harness continuity and expected signal types: sensor inputs are passive resistance measurements, relay outputs present switched line voltage to elements, and user input lines are digital/analog logic levels. Below are the main interface points typically encountered on the board for service reference.
- Sensor inputs (thermistor/RTD analog lines)
- Relay or triac outputs to heating elements
- Mains power input and internal DC power rails
- User input matrix and display connections
- Diagnostic/dialog pins for service mode
| Item | Description |
|---|---|
| Sensor input | Analog thermistor/RTD lines read by ADC for closed‑loop temperature control |
| Relay/SSR outputs | High‑voltage switching points that energize bake/broil elements or fans |
| Power supply | Mains conversion to regulated DC rails, standby clock power and protection devices |
| User interface | Keypad/display connections and scanned input matrix with debouncing |
Common Failure Symptoms, Error Codes and Diagnostic Indicators for the oven Control
The oven control board is the central electronic module that interprets user commands, drives the user interface, and controls power to heating elements and fans through relay outputs; the 318601500 Frigidaire Oven Control is an OEM replacement that performs these functions and must match the original connector pinout and mounting to be compatible. Technically, the control monitors inputs from the oven temperature sensor, thermal cutouts, and the thermostat, executes the control algorithm for bake/broil cycles, and reports diagnostic codes when it detects faults. In practice,a failed control will ofen present symptoms that overlap with sensor or wiring faults,so identifying whether the board,sensor,or harness is at fault requires targeted electrical checks rather than replacing parts on symptom alone.
- No display or blank clock while other power is present – possible failed power supply on the control or open incoming voltage circuit.
- Intermittent heating, elements not switching, or continuous heating with correct display – suspect relay failure or driver transistor on the board.
- Specific fault/error codes appearing on the display – these are diagnostic indicators; consult the service manual for exact code mapping for your model.
- Temperature drift or inaccurate oven temperature – verify oven temperature sensor resistance (≈1.1 kΩ at 25°C) and wiring before condemning the control.
- Physical signs: burned connectors, cracked solder joints, or swollen components around power relays often indicate board failure.
| Item | Description |
|---|---|
| Blank display | Loss of low-voltage supply or failed control power regulator; verify incoming line voltage and internal DC rails. |
| Error code on display | Model-specific mapping; start with sensor and harness checks, then test relay outputs if sensor is within spec. |
| Elements not switching | Measure line voltage at relay outputs; if mains present but no switching, relay/driver failure on the control is likely. |
For troubleshooting, begin with non-destructive verification: confirm correct incoming mains voltage at the oven junction and inspect the control harness for burnt pins or loose connectors, then measure the oven temperature sensor resistance and continuity of the heater circuits. use the appliance’s diagnostic mode and compare displayed codes against the Frigidaire service literature for the specific model; for example, a temperature-related code with a sensor reading near 1.1 kΩ indicates a wiring or sensor issue, whereas a correct sensor reading with no relay switching points to the control board. When replacing a control, ensure the replacement part number and PCB connector layout match the original 318601500 Frigidaire Oven Control to avoid compatibility issues, and transfer any interchangeable components (such as a separate keypad or harness) only after confirming thay are compatible with the replacement board.
Replacement Considerations: Model Compatibility, Wiring Harnesses and Step‑by‑Step Installation Guidelines
The 318601500 Frigidaire Oven control is an electronic control module that interprets user inputs, drives the display and keypad, and switches heater circuits through relays or triacs; confirm the replacement board matches the oven model series, connector layout, and labeled terminal functions before installation. Functionally, the control contains low-voltage logic, line-voltage switching outputs, and sensor input conditioning for the oven temperature probe; differences in connector pin counts, relay ratings, or firmware revisions can prevent proper element switching, produce error codes, or leave the display unresponsive.Compare the physical harness plug shapes and the service sheet pinout for the target model, and verify that any replacement board supports the same sensor type (thermistor vs. RTD) and control strategies used by your range or wall oven.
- Verify model and part-number compatibility and inspect connector pin counts and keying.
- Label and photograph all wiring before disconnecting to preserve terminal mappings.
- Check harness continuity and mains voltage at the terminal block with a multimeter.
- Handle the control board by the edges and observe basic ESD precautions.
| Item | Description |
|---|---|
| Connector Type | Match keyed multi-pin plugs; differing shapes or pin counts indicate incompatibility. |
| sensor Input | Confirm thermistor resistance curve or RTD specification to ensure correct temperature readings. |
| Relay/Output Ratings | Ensure outputs are rated for the oven’s element current and the expected mains voltage. |
for safe, repeatable replacement: disconnect power at the breaker and verify zero voltage at the appliance before touching terminals, then remove the chassis access panel and document each connection. After swapping the control, re-route the harness away from insulation and heat sources, secure strain reliefs, and restore power to perform functional checks – confirm keypad responsiveness, confirm the oven sensor reports a plausible temperature, and run a short bake cycle while monitoring element activation and error codes. If the replacement board’s harness connector or pinout does not match exactly, do not modify wiring by force; obtain the proper wiring harness or an adapter harness and consult the service manual wiring diagram for any necessary pin remapping.
Q&A
What is Frigidaire part 318601500?
Part 318601500 is an electronic oven control (also called an EOC or control board) used on certain Frigidaire electric ovens and ranges. It manages the display, user interface, timers and the oven’s heating cycles by switching power to bake/broil elements and processing sensor input.
How do I know if the 318601500 control board is bad?
Common signs include a blank or erratic display, unresponsive touchpad/controls, oven not heating or only heating intermittently, incorrect error codes, or visible damage on the board (burn marks, blown components or bulging capacitors). Before concluding the board is bad, check fuses, wiring, the thermal fuse/kit and the oven temperature sensor as those can produce similar symptoms.
Can I test the control board to confirm it’s faulty?
You can do preliminary checks: visually inspect the board for damage, verify household power is reaching the range, check the oven’s internal fuses, and read any error codes displayed. For a more definitive test a qualified technician measures voltages at the control board terminals and checks outputs to the bake/broil elements and the oven temperature sensor with a multimeter. Component-level testing/repair should only be done by someone experienced as live-voltage testing is hazardous.
Is replacing the 318601500 something I can do myself?
Many owners with basic appliance repair skills can replace the board: disconnect power at the breaker, remove the console or back panel, photograph and label all connectors, swap the board and reassemble. However, because mains voltages and fragile connectors are involved, stop and call a licensed technician if you’re uncomfortable working with electrical components.
Will I need to program or calibrate the oven after installing a new 318601500?
Most replacement boards are plug-and-play for functionality. You typically need to reset the clock and any user settings. If you notice temperature offset after replacement, perform the oven temperature calibration (or verify/calibrate the oven sensor) per your owner/service manual to ensure accurate temps.
How do I check the oven temperature sensor and what should its resistance be?
The sensor (a separate probe) should be checked with the oven unplugged: disconnect the sensor harness and measure resistance with an ohmmeter.Many Frigidaire sensors read roughly 1,000 ohms (about 1 kΩ) at room temperature, tho exact values vary by model-check your service documentation. A drastically different reading indicates a bad sensor rather than the control board.
Where should I buy a replacement 318601500 and how much does it cost?
Buy OEM parts from Frigidaire-authorized dealers, reputable appliance parts websites, or local appliance parts stores. Prices vary by seller and region but expect the control board to be a notable portion of a repair bill (hundreds of dollars including labor). Verify the part number against your oven’s model and serial number before purchasing.
Is it better to replace the control board or replace the entire oven?
Decide based on the oven’s age and overall condition: if the range is newer and in good shape otherwise, replacing the control board is usually cost-effective. If the oven has multiple major failures, poor energy efficiency, or is very old, replacement might be more economical. Consider repair cost, expected remaining life, and whether safety or reliability are concerns.
