318601500 Frigidaire Oven Control is an āelectronic oven controlā board assembly used in Frigidaire ranges āand ovens. It is a printed circuit assembly ā¢that combines the userā¢ interface, display/keypad inputs, control logic ā(microcontroller or processor)and power switching elements (relays or semiconductor switches) to manage ā¤ovenā functions. As āa ā¢primary control module, it replaces or repairs the oven’s central controlā¢ circuitry rather than āmechanicalā components such āas thermostats ā¢or heating ā¢elements.
Insideā the appliance the control board coordinates inputs and outputs āacross multiple subsystems:ā¢ it reads ā¢temperature feedback from the ovenā¢ temperature sensor/thermistor, actuates bake and broil heating elements or sends commandsā to gas ignitionā circuits, controls timers ā¤and user-selected programs,ā and interfaces with safety interlocks and āthe door lock āonā¤ models āthat include them. The board sits behind the ā¤control console or rear panel and bridges lowāvoltage user signals and mains power switching,so it ādirectly affects ā¤heating cycles,timing,andā¢ safety functions. Because it governs both command āsequencing and power delivery, its correctā¤ operation is essential for accurate temperature control, ā¤reliable cooking cyclesand safe shutdown in āfault conditions.
In this article you willā£ find a technicalā£ overview of the 318601500 control: how it functions, what systems and connectors ā¢to expectand common āmodel compatibilityā issues. The guide will describe typical ā¤failure symptoms (no display, unresponsive keypad, heating ā¤elements thatā£ do ānot switch on or thatā¤ remain energizedandā¢ diagnostic error codes), systematic troubleshooting steps (visual inspection, ā¤connector and harnessā¤ checks, sensor verification, āand voltage measurements at key terminals)and practical ā¤replacement considerations (electrostatic precautions, verifying āpart ā¢fit and connector pinout,ā£ and postāinstallation checks). Safety and correct diagnosis āare emphasized to avoid misattributing faults to the control when the āroot cause is a ā¢sensor, harnessor power-supply issue.

Function and Roleā of theā Ovenā Control Module in Frigidaire Ranges
The 318601500 Frigidaire Oven Controlā is ā¢the printed circuit board āthat coordinates all timed and temperature-driven activities insideā the range. It receives inputs from the userā interface, the ā¢ovenā¤ temperatureā sensor, door-lock switches and safety interlocks, than āsequences outputs – typically relays or triacs – to the bake āand broil ā¢elements, convection āfanand gas ignition ā¢circuitry where applicable. Theā¤ control alsoā£ manages timers, preheat logic and the self-cleanā¢ sequenceand records diagnostic fault codes in non-volatile āmemory soā¤ a technician can isolate electrical, sensoror user-interface failures without guessing at component-level behavior.
In operation the board converts sensor resistance into āaā temperature reading, enforces temperatureā setpointsā with closed-loop control, ā¢and protects theā¢ appliance by disablingā heating circuits when unsafe conditions areā£ detected. When evaluatingā compatibility ā¤or replacing the module,confirm the exact ā£model fit,connector āpinout,and harness arrangement since chassis ārevisions can change relay ratings and signal assignments; after replacement,verify oven response with a calibrated āthermometerā andā check recorded diagnostics. Common failure indicators that point to the controlā ratherā£ than an elementā or sensor include a functioningā£ display with no element switching, intermittent oven operation tied to specific modesor persistent control-panel error codes that continue afterā other components ātest good.
- Typical symptoms: no heating while ā¤displayā is active, elementsā¤ not energizing, inaccurate or unstable oven temperatureorā recurring diagnostic error codes.
| Item | Description |
|---|---|
| bake/Broil Relay | high-voltage switchingā¤ devices on ā¤the board that supply the oven ā¢elements or activate gas valve/igniter sequencing. |
| Temperature Sensor Input | Analog input that measures RTD/thermistor resistance and feeds the control’s temperature ā£algorithm. |
| user Interface Connection | Ribbon/harness link for keypad, display andā diagnosticā£ mode access; mismatch here preventsā¤ proper command ā¢interpretation. |
| Power / Logic Supply | Board power stages that provide low-voltageā¤ logic and high-voltage switching; failures here can leave the display on while outputs āare dead. |
How the 318601500 Frigidaireā Oven Control works Inside the Appliance
The 318601500 Frigidaire Oven ā£Control is the main logic and powerā interface board that coordinates temperature regulation, user inputs, timersand safety ā£interlocks inside the oven.ā It reads the ā£oven temperature via the oven sensor (an NTC thermistor), runs control algorithms to modulate bake/broil/convection outputsand switches those heating circuits throughā¢ relays or triacs.Theā¤ board also monitors āfor fault conditions (open/short sensor,door latch faults,supply voltage anomalies) and drives the display/keypad so the user can select modes and temperatures.Physically the unit connects to theā£ appliance through a ā¤multi-pin wiring harness, so mechanical connector compatibilityā and firmwareā revision are important when sourcingā¢ a replacement.
For practical troubleshooting and service, technicians treatā¢ the control āas both a logic controller and a power distribution device: verify incoming line voltage at ā¤the board, measure sensor resistance againstā expected values, ā£and observe weather the board’s bake or broil ā¤outputs switch to supply element voltage when a cook cycle is selected.If the ovenā£ displays sensor error codes or elementsā never energize despite correct inputs, the ā¢boardā£ outputs or the control’s sensing network are suspect; conversely,ā steady temperature overshoot canā indicate aā¤ failed sensor or a control that’s not modulating properly. When replacing the control, āmatch the 318601500 Frigidaire Oven ā¤Control to the applianceā model and connector pattern to avoid mismatches in wiring or feature set; after replacement, confirm ā¤clock/timer āsettings and run aā¤ short bakeā¤ cycle toā£ validate proper element switching and temperature response.
- Sensor input: oven thermistorā¢ monitoring for closed-loop temperature control
- Power outputs: relays/triacs for bake, broiland convection elements
- Userā interface: keypad/displayā and non-volatile āclock/timerā memory
- Diagnostics: error reporting for sensor faults andā supply anomalies
- Mechanical: multi-pin OEM wiring harnessā¢ required for compatibility
| Item | Description |
|---|---|
| Input voltage | 120/240 VAC depending on ā¤oven configuration; verify line ā¤voltageā£ at harness |
| Sensor type | NTC thermistor (approx. 1ā kĪ© at 25Ā°C) used for temperature feedback |
| Power outputs | Relay or triac-switched ā£circuits for bake, broilā and fan/convection elements |

Common Failure Symptoms and Diagnostic Indicators for the oven Control
The 318601500 Frigidaire oven Control ā¤is the ā¢central electronic module that interprets user commands, monitorsā the oven temperature sensor, ā£and drives the bake/broil outputs or solid-state switching elements to achieve and regulate setpoints.ā¤ Failures manifest as electrical, controlor feedback faults rather ā¤than purely mechanical problems: ā£a ādefective board ācan present a dead or erratic display, persistent appliance fault codes, relaysā¢ that do not energizeor incorrect temperature control. Before replacing the assembly, verify mechanical andā¤ sensor ā£inputsā¢ and confirm that the replacement board āmatches the oven model and harness pinout, because ā¤variant controls may use different āoutputā¢ arrangements orā¤ firmware that affect timing, ā¢safety āinterlocksand diagnostic behavior.
- Display/Keypad failure: noā¢ response or garbled characters-check low-voltage logic supply and ribbonā connector continuity.
- No heat or constant heat: relay/SSR ā¢outputs stuckā£ openā£ or closed-inspect output transistors/relays and wiring to ā£the heatingā elements.
- Intermittent cycling or inaccurate temperature: loose āconnector, failing triac/SSRor sensor out of specification.
- Persistent error codes or āaudible clicking: record codesā andā sounds;ā¤ they often point to sensor faults, power supply collapseor worn relay coils.
- Failure after power ā¤surge or moisture exposure: visible board damage, blistered componentsor corrosion around connectors.
| Item | Description |
|---|---|
| Unresponsive ādisplay | Measure board logic āvoltagesā¢ and inspect the UI ribbon;ā no logic voltage āindicates ā¤power-supply or fuse failure upstream of the MCU. |
| Incorrect temperature regulation | Compare oven ā£sensorā resistance to service specificationsā£ and observe relay/SSRā¤ drive whenā heat is commandedā to isolate ā¢sensor vs. output faults. |
| Persistent fault codes | Document the code, consult the service manualā¤ for its meaning, then test the implicated components (sensor, connectoror outputs) before concluding a board replacement. |
Diagnose systematically: isolateā¢ mainsā£ power, visually inspect for burned components and connector ā¤corrosion, then restore power to measure supply ārails, control signalsand outputā switching under command with appropriate ā¤safety precautions. For example, if the oven clicks butā does not heat, verify that the control is issuing a drive signal to the relay or SSR and measure the element circuit forā continuityā and proper line voltage; if ā£the control drives theā¢ output but theā£ element does not receive āvoltage, the fault is in theā£ wiring or element, ānot the control. āWhen replacing theā¢ board, match part number, harnessand functional ā£features; a correct mechanical fit ādoesā£ not guarantee compatibility if the āreplacement uses different ā£firmware or relay āassignments.
Replacement Considerations and Step-by-Step Installation āGuidelines
The 318601500 Frigidaireā Oven Control is ā¤the printed circuit board that coordinates user inputs, displayā¤ functions,ā£ element switchingand temperature feedback on compatibleā Frigidaireā ranges. The board containsā relay ā¢or triac outputs that switch bake/broil elements,ā¢ analog or digital inputs for ā¤the oven ātemperature sensorand logic circuits for āthe keypad and ādisplay; failures can present as unresponsive controls, persistent error codesorā¤ heating elements that do not cycle. Before replacement verify the part number andā boardā¢ revision against the āappliance model and service sheet, confirm connector pin countsā and harness compatibilityand inspect the ā£oven temperature sensor and high-limit fuses because thes peripheral failures commonly mimicā£ control board faults.
Follow ā¢a methodical replacement ā¤and āvalidation workflow to avoid diagnostic ambiguity or damage: disconnect power at the breaker and confirm zero voltsā£ at the control āharness,ā document or photograph ā¤all connector positions and wire colors, then remove āmounting fasteners and transferā¢ sensors and harnesses to the replacement board. Afterā¤ reassembly,ā¢ restoreā power and run aā controlledā£ test (display/clock set, ādiagnostic mode if availableand aā short bake/broil cycle) while monitoring element activation andā¤ oven temperatureā¢ with anā external thermometer; check ā¢for error codesā£ and reconfirm proper operation of timed functions and safety interlocks.
- Safety and verification: ā¤disconnect power, verify harness pinoutand inspect ā¤fuses/thermistor ā¤before swapping boards.
- Documentation:ā£ photograph connector locations, label wires,ā£ and ānote boardā£ revision numbers.

Q&A
What ā£is the 318601500 Frigidaire Oven control and what does it do?
The 318601500 is aā Frigidaire electronic oven control assembly (the ācontrol board/user interface āand āassociated electronics) used ā¤on certain āFrigidaire ranges/ovens. It manages the clock, timers, ākeypad/displayand the switching of bake/broil/clean circuits (via relays or solid-state outputs) and processes input from the ovenā¤ temperature sensor to regulate heating.
How can Iā¢ tell āif the 318601500 control is failing?
Common symptoms of a failing āoven controlā¢ include an unresponsive or ā¢blank display,ā keys ā¢thatā don’t register, oven not heating while display appears normal, ovens thatā¢ start heating butā then act erratically (random shutdowns or temperature swings)or ā¤persistent error codesā tied āto control/keypad ā¤faults. Always rule out obvious issuesā£ first (blown fuses, tripped breakers, badā element, loose wiring,ā¤ or a failed temperature sensor) before concludingā¢ the control board is bad.
How do āI diagnose whether the ā¤control board is the problem?
Start ā¤by cutting power at the breaker. Visuallyā inspectā the control board for burned components, cracked solder jointsor corrosion. With powerā restored and proper safety precautions, āuse aā multimeter to verify the board is receiving ā¤line voltage āand thatā¤ the boardā is supplying voltage toā¢ the ābake/broilā¢ elementā outputs whenā theā¢ oven ā¤is ā£calling ā¢for heat.ā£ also measure the oven temperature sensor resistance ā(compare to the ā¤value in the service āmanual-manyā¤ NTC-type oven sensors are roughly 1.0-1.2 kĪ© at room temperature). If the board āhasā¤ inputā¤ power and the sensor is good but ā¢the board does not energize the outputs, the control is likely defective. if unsure, consult aā¤ qualified technician.
Can Iā£ replace ā£the 318601500 myself ā¢andā£ what ā¤safety steps shouldā I follow?
Yes, āan experienced DIYerā£ canā replaceā the control, butā you āmust disconnect all āpower at the circuit breaker beforeā starting.
