316490001 Frigidaire oven Temperature Sensor Probe is a resistive temperature⤠sensor used in Frigidaire ovens and ranges; it is â˘indeed typically implemented as a thermistor-style probe that converts oven-cavity temperature intoâ a measurable electrical signal for the controlâ electronics. As a discrete sensing element, the probe consists of a temperature-sensitive resistor mounted inâ a protective sheath âŁwiht a wiring harness and connector sized to match factory appliance wiring.The part number identifies the specific OEM form factor, connector âtypeand mounting arrangement used on compatible Frigidaire models.
Inside the appliance, the temperature sensor probe provides real-time temperature feedback to the oven control board and, where present, the temperature regulation subsystem (timedâ heating cycles, convection controland safety limits). It interacts electrically with the main control board’s input circuitry and mechanically with the oven liner or mounting âŁbracket that positions it in the cavityâ toâ measureâ representative â¤air temperature. Correct functioning ofâ the probe is essential⣠for closed-loop temperature control:⤠the control board uses the probe signal to⣠decide when to apply or remove power from the heating elements⣠and to â¤detect out-of-range or fault conditions.
In this articleâ readers will find a technical overview of how âthe 316490001 probe functions, guidance on model compatibility and identifying the correct replacement, common failure symptoms (open/short circuit, driftor intermittent readings), âŁand stepâbyâstep troubleshooting methodsâ including resistance checks and wiring inspections. âThe âarticle also covers practical replacement considerations such as âconnector type, probe length and mounting orientation,â and â˘basic verification procedures after installation to ensure accurate oven temperature regulation.

function and Role of the Oven⣠Temperature Sensor Probe within Frigidaire Oven Control Systems
The 316490001 Frigidaire Oven Temperature Sensor Probe is a twoâwire thermistor that translates oven cavity âŁtemperature into a variable electrical resistance for the oven control board. As a negative temperature coefficient (NTC) device, it’s resistance falls as temperature rises;â the control boardâ interprets this resistance toâ regulate bake and broil elements, implement preheat timingand maintain setpoint stability. in practice⤠the sensor provides continuous, realâtime temperature feedback rather than on/offâ switching, which â¤enables proportional control algorithms and more stable oven temperatures across different modes and loads.
- Primary role: provide accurate, repeatable temperature feedback to⢠the control board.
- Common symptoms of failure: slow or no preheat,⤠persistent temperature error codes, oven cycling erratically,â or sustained over/under temperature.
- Replacement considerations: match the sensor’s resistance curveâ and connector type to â¤the control board; mechanical mounting and probe location â˘affect readings.
| Item | Description |
|---|---|
| Sensorâ type | NTC thermistor (twoâwire probe providing resistance vs. temperature) |
| Typical electrical note | Resistance decreases withâ temperature; nominalâ roomâtemperature resistance varies by design (verify against service specification before replacement) |
| Compatibility | Designed for use⤠with Frigidaire oven⣠control systems that accept a âtwoâwire⢠temperature sensor; confirm connector, mountingand resistance curve when substituting |
Technicians diagnosing ovenâ temperature issues commonly measure the sensor’s cold resistance withâ a multimeter and compare it to the manufacturer’s specification or to a known good sensor; a significantly outâofâspec reading or open circuit indicates replacement.â When installing a 316490001 âsensor or a compatible equivalent, âŁensureâ the probe is positioned and secured in the original âmounting location so the⤠control⣠board receives representative cavity temperature. Using â¤a sensor with a different resistance curve or different⣠probe placement âcan produce erroneous control behavior⤠even if the connectorâ fits physically.
How the 316490001 Frigidaire Oven Temperature Sensor Probe Works âInside the Appliance
The 316490001 Frigidaire Oven Temperatureâ Sensor Probe â˘is a sealed sensing element, typically âan NTC thermistor, installed inside the oven cavity to provide the control âboard withâ a temperature-dependent resistance. As the cavity temperature changes, the sensor’s resistance decreases, producing a measurable voltage change across the control board’s reference circuit; the board interprets that voltage and adjusts bake/ broil element duty cycles to maintain setpoint. The probe’s physical location (usually near the oven â˘rear wall) and low thermal mass allow it to represent the⣠oven⣠air temperature reasonably âquickly,and the part interfaces to the appliance via âa twoâpin connector and a short⤠harness that must match the range wiring⤠for compatibility.
Technicians evaluate the sensor by⤠measuring resistance and observing its monotonic change with temperature: a functioning probe shows a predictable resistance at ambient⣠temperature and decreases smoothly âas heat is applied. An open circuit, erratic readingsor âa resistance that differs⤠substantially from â¤the expected range indicate failure and will cause the controller to display error codes orâ run â˘incorrect cycles (overheating,â underheating, long preheat).Replacement requires matching the 316490001 Frigidaire Oven Temperature Sensorâ Probe’s connector, lead lengthand mounting clip; swapping a compatible sensor restores accurate closedâloop temperature control without modifying the control board.
- Common failure symptoms: inaccurate oven temperature,â long preheat times, intermittent temperature faultsor error â˘codes related to the sensor circuit.
- Basic bench test: measure resistance at ~25 °C â¤and then again while warming; resistance should fall smoothlyâ (no jumps or open readings).
- Replacement considerations: verify connector type, lead lengthand mounting orientation to ensure proper sensing and fitment.

Common Failure Symptoms, Resistance Readings and Observed Oven Behavior
The â316490001â Frigidaire â¤Oven Temperature Sensorâ Probe is an NTC â¤thermistor-style probe used by many Frigidaire range modelsâ to âprovide the control board with real-time oven cavity temperature.The probe senses temperature by changing resistance: âŁas oven⤠temperature rises the resistance⢠falls. In practical terms the control board reads that resistance to regulateâ bake/ broil elements and to⣠display oven⢠temperature; compatibility depends on connector type and the board’sâ expected resistor curve, âŁso confirm the two-pin connector and mounting location match the original before replacing the sensor.
- Symptoms: oven runs too⤠cool or too hot, long or inconsistent preheat times, temperature overshoot/undershootor intermittent âŁfaults⤠and error codes related to temperature sensing.
- Multimeter checks: an open circuit (infinite resistance) or ânear-short âindicates failure; a â˘steady resistance markedly different from the expected room-temperature value suggests a degraded sensor.
- Behavior: intermittent resistance changes under no-temp-change â˘conditions often produce âcycling elements âŁand unstable âoven temperature.
technicians typically confirm operation⤠by measuring resistance at ambient temperature and comparing it to the expected value for the model; many Frigidaireâ oven sensors readâ on the â˘order of 1.0-1.2 kΊâ at roughly 20-25 â°C, though exactâ nominal values vary by design. âIf resistance changes smoothly and predictably with applied â¤heat (useâ a controlled heat source or compare against published⢠resistance-vs-temperature curves) the sensor is functioning.Replace â¤the probe if readings are erratic, outside the expected tolerance bandor if physical⢠damage/corrosion âis present, as a marginal sensor canâ cause persistent control-board cyclingâ and inconsistent cookingâ results.

replacement Considerations, Installation Procedure and âŁPost-Install Calibration
The 316490001 Frigidaire âOven Temperature Sensor Probe is a thermistor-style sensing element⣠that changes resistance⢠with temperature and communicates oven cavity temperature to the ârangeâ control board. The control board converts that resistance into a temperature reading used to cycle the bakeâ andâ broil elements; a sensor thatâ is out of tolerance, shortedor open will cause incorrect temperature regulation, long heat âcyclesor âdiagnostic fault codes.â This probe is a direct-fit replacement where the âoriginal â˘sensor uses the same twoâwire connector and â˘mounting âbracket; compatibility depends on the range model’s harness and mounting âŁlocation rather âthan the sensing element alone.
- Power off and isolate the appliance before accessing⢠the rear panelâ and sensorâ bracket.
- Verify the twoâpin connector and wiring for⤠corrosion or damage before âreplacement.
- Mount the sensor tip âcentered in the oven cavity without contact withâ sideâ walls or insulation.
- Measure ambient resistance âwith âa multimeter (typicalâ reference ~1.1 kΊ at room temperature) âŁand check for âopen/short âŁafter installation.
- Perform a bake verification âwith an self-reliant oven thermometer and apply model-specific calibration⤠if a consistent offset remains.
Installation requires removing the back âpanel or âinterior access plate,unscrewing the retaining bracket,disconnecting the twoâwire plug,and transferring the probe to the new⢠bracket âŁand harness. After reassembly, verify electrical continuity and that the resistance at ambient temperature matches the expected thermistor⢠curveâ for the sensor; a simple twoâpoint check (ambient andâ after a âcontrolled warm-up) confirms proper⤠response. If measured oven⣠temperature deviates by a consistent amount⢠(for example, an independent thermometer reads â20°F lower at â350°F), confirm correct sensor positioning and wiring before â˘using the oven’s temperature offset or service calibration procedure-refer to the appliance âservice manualâ for the exact calibration sequence for your model.

Q&A
What is the 316490001 Frigidaire oven temperature sensor probe and what does it do?
The 316490001 is anâ OEM oven temperature sensor (a thermistor) used in many Frigidaire electric ovens/ranges.â It measures⣠the oven cavity temperature and sends that signal to âŁthe ovenâ control board so the controller can maintain the set temperature by cycling the heating elements.
What are common symptoms of a failing 316490001 âsensor?
Typical symptoms include the oven âŁnotâ reachingâ the set⤠temperature, temperature fluctuating widely, very long preheat times,⣠or the oven⤠running too hotâ or too cool. A failedâ sensor may also cause temperature-related error messages on some models.⤠Mechanical⤠damage or visible corrosion on the probe can also indicate failure.
How do I safely â¤test the 316490001 sensor with â˘a multimeter?
Disconnect âŁpower to the range (unplug or turn off the breaker). Access the sensor (usually inside the⤠oven at the âback wall), unplug âthe two-pinâ connector⣠or remove âŁthe sensor âŁfrom the oven and test âacross the two terminals with a digital âmultimeter set to ohms (Ί). At⤠room temperature (~70°F / 21°C) you should typically see around 1,000-1,100 ohms (values can vary by a few hundred ohms depending on design). Resistance should change noticeably when âthe probe is heated (e.g.,â with a⤠hair dryer). An âŁopen reading (infinite) or a short⣠(near 0 Ί)â indicates a badâ sensor.
Canâ I test the sensor âwithout removing⤠it from the oven?
You can often test it in placeâ by first disconnectingâ power and unplugging⣠the sensor’s two-pin harness to measure resistance across the two terminals. Testingâ while the sensor is still connected to the control board is not recommended because other circuitry can affect the reading.⣠For the⣠most accurate result, remove or at âleast unplug âŁthe sensor before measuring.
Is the 316490001 sensor compatibleâ with âŁmy Frigidaire model?
316490001 fits many Frigidaire electric ovens and ranges but not all.⣠Always verify compatibility using your appliance model number (usually on a tagâ inside⤠the oven door frame, behind the kick⢠plateor on the back of the range) and â˘cross-reference that with the âpart listing from theâ manufacturer or âŁan authorized parts supplier before purchasing.
How do âŁI replace the⤠316490001 sensor and what tools are ârequired?
Basic â¤replacement steps: 1) Disconnect power at â¤the breaker or unplug the range. 2) Open the oven â˘and remove the oven racks.3) Locate the⣠sensor at the back wall, remove the mounting screwsand pull the â˘probe forward toâ access the two-pin connector. â˘4) Disconnect the harness, swap in the new â˘sensor, reconnectand remount with screws.⤠5) Restore power and test. Common tools needed are⢠a screwdriver â(usually Phillips), needle-nose âpliers, â˘and a multimeter for testing. Allow ~15-30 minutes for the job âif you’re pleasantâ with basic appliance repair.
Can I recalibrate the oven rather of replacing the sensor?
Many ovens have a temperature offset or calibration feature in theâ control that can correct âsmall,consistent temperature differences.â However, if the sensor is⣠faulty (giving incorrect or unstable resistance), calibration will not reliably â˘fix âthe problem and you should replace the â˘sensor. Test the sensor⣠first to determine weather replacement is necessary.
How much does the 316490001 sensor cost and should I hire a technician?
Replacement sensors are generally inexpensive as parts (typically in the $20-$60 range),but âŁlabor costs vary if you⢠hire âŁa technician. If âŁyou areâ comfortable disconnecting⢠power and handling simple screw-and-plug replacements, it is a common DIY job.⢠hire a qualified appliance technician if you are unsure, uncomfortable working with electrical appliancesor if the issue mightâ involve the control board or⤠wiring.
To Wrap It up
The 316490001 Frigidaire oven âŁtemperature sensor probe serves asâ the âŁoven’s primary temperature-sensing element, providing the control board with real-time feedback to regulate heating cycles. Accurate sensing is essential for consistent cooking results, energy-efficient operation,⤠and âprevention of overheating or prolonged bake times;⣠a properly functioning sensor therefore contributes directly to oven performance, food qualityand appliance longevity.
Because temperature-related symptoms âŁcan arise from wiring, control electronicsor the sensor itself, careful diagnosis is vital before replacing parts. When â˘testing or replacement is required, using the correct OEM part and following manufacturer-recommended procedures or enlisting a qualified âservice technician helps ensure compatibility, safe⣠installationand restorationâ of accurate â¤temperature control.
