318601500 frigidaire Oven Control is the electronic control assembly used to manage and coordinate oven functions on compatible Frigidaire electric ranges and wall ovens. The component is typically a printed circuit board (PCB) and user interface module that contains the microcontroller, display and keypad interfaces, input/output drivers, and power-handling components required to execute cooking programs and safety sequences.
Inside the appliance, the oven control acts as the central logic and timing unit: it receives user inputs, reads temperature feedback from the oven sensor (thermistor or RTD), switches power to bake/broil/heating elements or solid-state relays/triacs, controls convection fans and timers, and monitors safety interlocks such as door locks or over-temperature protection. It therefore interfaces with low-voltage inputs (keypad, sensors), line-voltage circuits (heating elements, relays), and diagnostic/error reporting systems, coordinating those subsystems to maintain set temperatures and operational states while protecting the appliance and user from unsafe conditions.
In this article readers will find a technical overview of the 318601500 control’s intended functions and typical applications, guidance on model compatibility and part cross-references, common failure symptoms to recognize (for example unresponsive controls, incorrect temperature regulation, or display errors), structured troubleshooting approaches (visual inspection, harness and connector checks, sensor resistance and voltage measurements, interpreting error codes), and practical replacement considerations including part verification, safety precautions, ESD handling, and post-installation checks. The information is aimed at technicians, engineers, and informed appliance owners who need a clear understanding of the component’s role and service implications without manufacturer marketing language.

Function and Role of the Oven Control Module in Temperature Regulation and User Interface
The 318601500 Frigidaire Oven Control functions as the primary control board that manages temperature regulation and coordinates the user interface. It continuously reads temperature feedback from the oven sensor (thermistor), compares that feedback to the selected setpoint, and modulates heater power by switching the appropriate outputs (bake, broil, convection fan) using relays or solid-state devices. The board implements the control logic-ranging from simple on/off duty cycling to more refined control algorithms-to minimize overshoot and achieve repeatable preheat and hold temperatures. Compatibility matters: replacement controllers must match the oven’s wiring harness, sensor type, and connector pinout because differences in sensor curve, output type, or input voltage reference will change the control behaviour and can produce incorrect temperatures or erroneous fault codes.
- Sensor inputs: thermistor/temperature feedback and door or safety interlocks
- Control outputs: element relays/triacs, convection fan, and door lock actuators
- Interface and logic: keypad/display handling, setpoint storage, preheat and timer sequences
- Diagnostics: sensor fault detection, relay state monitoring, and error reporting for service technicians
On the user interface side, the control translates button presses and knob positions into operational commands, drives the display and indicator lights, and maintains timing and program states (timed bake, delayed start, or temperature hold). It also exposes serviceable diagnostics: for example, an open or shorted thermistor will typically produce a specific fault code and inhibit heating, while stuck or chattering relays produce intermittent heating symptoms that the technician can verify by observing relay coil activation and output continuity. Practical troubleshooting therefore combines UI symptoms (unresponsive keys, incorrect display readout) with electrical checks at the control’s connectors (sensor resistance vs. temperature, relay coil voltages) to determine whether to repair wiring/sensors or replace the control module.
How the 318601500 Frigidaire Oven Control Works Inside the Appliance: Circuitry, Relays, and Sensor Interfaces
The 318601500 Frigidaire Oven Control is the appliance’s electronic command center: a microcontroller-based module that translates user inputs and timer settings into the line-voltage switching actions that drive bake, broil, convection fan, and oven light circuits. Internally the board contains mains input protection and filtering, relay or triac switching stages, relay-driver transistors or opto-isolators, and an analog front end for the temperature sensor. In normal operation the control reads the oven temperature sensor, executes a temperature-control algorithm (time-proportional or PID-like duty control), and energizes the appropriate switching devices to maintain setpoint; it also monitors interlocks (door lock, thermal cutoff) and communicates status to the user interface. Because heating elements and the switching hardware are on the line-voltage side, technicians should remember that the board integrates both low-voltage logic and high-voltage power sections and that replacement requires matching the exact part number and harness pinout for safe compatibility.
The control’s sensor interface typically expects a resistive temperature sensor (NTC thermistor or RTD) wired to an ADC input with a precision pull-up/pull-down and filtering; the board implements open/short detection and will generate fault codes or inhibit heating if the sensor value is out of range. On the power side, the board uses mechanical relays or semiconductor switches to route mains to elements and fans; common failure modes are welded relay contacts, failed triacs, or damaged driver components. Practical troubleshooting steps include measuring the sensor resistance against the oven’s service spec, confirming coil continuity on mechanical relays or checking for gate drive on semiconductor switches, and verifying connector pin assignments between the harness and the replacement board. Exercise caution during live tests because relay/element circuits are mains-voltage and remain hazardous even when the control logic operates normally.
- Typical symptoms indicating control or interface issues: elements never energize, oven overheats, persistent sensor fault codes, or user-interface unresponsiveness.
- common checks: sensor resistance, harness continuity, relay coil/driven outputs, and board visual inspection for burned traces or bulging components.
| Item | Description |
|---|---|
| temperature sensor input | Analog ADC with pull-up; open/short detection and temperature-to-code conversion. |
| Switching stage | Mechanical relays or triacs that apply mains to bake/broil/convection elements. |
| Safety interlocks | Inputs for door lock, thermal cutoff, and high-limit thermostats that inhibit heating when triggered. |
Common Failure Symptoms and Electrical Fault Indicators for Oven Control Malfunctions
The 318601500 Frigidaire Oven Control is the central electronic module that sequences the oven’s timers,display,user interface,and power switching for the bake/broil elements. Failure of this control typically produces symptoms that overlap with wiring, element, or thermal-protection failures, so diagnostic steps should separate user-interface errors (blank or erratic display, unresponsive keypad) from power-switching faults (elements not energizing, elements stuck on). This control interfaces with the range harness and sensors; confirm connector pinouts and model compatibility before replacing the board to avoid mismatched relay ratings or harness configurations.
- Blank, flickering, or garbled display while oven elements do not respond.
- Unresponsive or intermittent touchpad/controls despite powered clock.
- Oven fails to reach set temperature,or cycles incorrectly-elements do not switch on or remain energized continuously.
- Unit trips breakers or blows fuses when specific functions are called.
- Visible damage at board connectors, burned components, or odor of overheating indicating electrical fault.
Electrical fault indicators for the oven control are primarily measurable: verify line voltage at the range (typically 208-240 VAC across L1-L2) and the control’s logic supply (commonly ~120 VAC from L1 to neutral on many Frigidaire models). Use a multimeter to check for voltage at the control’s element output terminals while the controller is calling for heat-if proper line voltage is present at the control’s output but the element does not draw current,the element or its connections are suspect; if voltage is absent,the control’s switching device (relay or triac),an on-board fuse,or a failed driver circuit is more likely. Inspect for intermittent shorts to chassis ground, blown board fuses, swollen capacitors, or scorched traces; these are strong indicators that the control has suffered an electrical failure rather than a simple sensor fault. safety: disconnect main power before probing or replacing the control, and document harness pin assignments to ensure correct reconnection.
| Item | description |
|---|---|
| Supply voltage | Expect ~208-240 VAC across L1-L2; absence indicates supply or incoming breaker/fuse issue. |
| Control logic supply | Expect ~120 VAC (L1 to neutral) on many models to power the display and CPU; no logic voltage with oven powered indicates blown thermal fuse or board power regulator failure. |
| Bake element resistance | Typical low-ohm reading (often between ~10-50 Ω depending on element length); open circuit indicates failed element. |
| Relay/triac output | When calling for heat, output terminal should present line voltage; no output points to failed switching component on the 318601500 control. |
Replacement Considerations and Installation Procedures for the 318601500 Control Module
The 318601500 Frigidaire Oven Control is an electronic control module that coordinates user inputs, oven temperature regulation, and power switching to the bake and broil elements. This board contains the user interface PCB, low-voltage logic, temperature-sensor input and one or more high-current switching devices (relays or triacs). Before replacement, visually confirm the board part number and connector pinouts against the oven model plate as identical-looking controls can have different harness pin assignments or sensor-scaling firmware. Failures that indicate a control-module fault include persistent error codes, unresponsive keypad/display, continuous element heating with no thermostat response, or intermittent switching; tho, similar symptoms can also be caused by a failed oven sensor, shorted element, or wiring harness fault, so isolate and verify those components frist.
Follow a controlled installation procedure to avoid damaging the new module and to restore safe operation: de-energize the range at the breaker, document the wiring layout with photos, discharge any stored voltage on capacitors, and observe basic ESD precautions when handling the PCB. After replacing the board and re-seating all connectors, confirm mechanical mounting and clearances, then power the oven and run a functional verification sequence (display checks, diagnostic mode if available, and a short bake cycle while monitoring sensor resistance and element switching). Typical checks and steps useful for technicians are listed below.
- Verify the replacement part number against the unit’s model and the PCB silk-screen before disconnecting harnesses.
- Shut off power at the breaker and photograph wiring to preserve connector locations and orientation.
- Check oven sensor resistance (room temperature ~1100-1200 ohms for most NTC sensors) before and after swap.
- After installation,test bake/broil cycles and observe element on/off cycling and any stored error codes via the service diagnostic mode.
| Item | Description |
|---|---|
| Connectors | Multiple keyed harness connectors (verify pin count and orientation; some variants use different pinouts despite similar housings) |
| Switching Devices | relays or triacs on the board control high current to elements; heat damage or short circuits commonly disable switching |
| Diagnostics | Service mode verifies display, keypad, sensor input, and relay actuation – useful to confirm prosperous replacement without full bake cycle |
Q&A
What is the 318601500 Frigidaire oven control and what does it do?
318601500 is the electronic user interface and oven control (frequently enough called the clock/control board) used in certain Frigidaire ranges.It handles the timer/clock/display, keypad input, and low-voltage logic and drives the high-voltage relays or triacs that switch bake, broil, convection fan, and other oven outputs. In short, it’s the central control that runs oven functions and reads temps/timers.
What are the common symptoms of a failing 318601500 control?
Common symptoms include a blank or garbled display, unresponsive keypad/buttons, oven functions not starting when selected, elements that are on continuously or not at all (stuck relays), random cycling or error codes, and visible burnt components or corrosion on the board. As other parts (wiring, thermal fuse, temperature sensor, elements) can cause similar symptoms, proper diagnosis is critically important.
How can I tell whether the control is bad or something else (sensor,element,wiring)?
Begin with non-invasive checks: confirm the range has proper incoming power and inspect connectors for burns or loose wires. Verify the oven temperature sensor resistance and element continuity with a multimeter. If the control display is dead but incoming power is present at the board’s harness, or if relays are not switching outputs correctly while inputs are valid, the control is suspect. Because mains voltage is involved, basic testing is okay for a trained person; otherwise have a qualified technician diagnose it.
Can I replace the 318601500 myself, and what safety precautions should I take?
Yes, a competent DIYer can replace the control, but always disconnect power at the circuit breaker before accessing the control. Take photos of wiring harness positions before removal, avoid touching plated contacts or circuitry with bare hands, and reattach connectors correctly. If you are uncomfortable working around live mains or removing panels, hire a qualified appliance technician.
How do I confirm that 318601500 is the correct replacement for my oven model?
Check the oven’s model number (found on the frame behind the door or on the oven’s information tag) and compare it to the part listing from Frigidaire or an authorized parts retailer. Confirm the part number printed on the existing control and verify connector pin locations and mounting points match. When in doubt, provide your oven model number to the parts supplier or Frigidaire customer service for confirmation.
Will replacing the control fix temperature accuracy problems?
Not always. Temperature inaccuracy is often caused by a failing oven temperature sensor or incorrect calibration settings rather than the control board itself.The control can be at fault if it misreads the sensor signal or if its internal calibration is corrupted, but you should first check the sensor resistance and try oven calibration/adjustment options in the user/service menu before replacing the control.
How do technicians normally test the control outputs without replacing it right away?
Technicians typically verify incoming mains voltage to the board, check the control’s low-voltage power supply, and then command bake/broil while measuring the control’s output pins/harness for the presence of voltage to the element. They also inspect the board for burned traces, blown components, or swollen capacitors. As these checks involve mains voltage, they should be done by someone experienced with safe electrical procedures.
How much does a replacement 318601500 cost and is ther a warranty?
Price varies by source and whether the board is new or refurbished; typical retail prices are often in the low hundreds of dollars. Labor to install (if you use a technician) is additional. Parts sellers commonly offer limited warranties (for example 90 days to one year) on controls-confirm the exact warranty and return policy with the seller before purchase.
