Quick Answer: Why Your Frigidaire Oven Runs at the Wrong Temperature#
Most likely: the oven temperature sensor (Frigidaire part 316490000) has drifted. It should read about 1,080 ohms at room temperature, and as it ages it reports a false value that pushes the actual cavity temperature off by tens of degrees — enough to under- or over-bake everything. Before replacing parts, check the simple one: Frigidaire lets you dial in a calibration offset, so an oven that is uniformly a bit off may just need recalibrating. After the sensor and calibration, a failed convection fan on Gallery models and a partially failed bake element are the other usual causes.
Likely Causes at a Glance#
| Cause | Likelihood | What to check |
|---|---|---|
| Temperature sensor drift (316490000) | Most likely | sensor near 1,080 ohms at room temp; drift throws the reading off |
| Calibration offset needed | Common | a uniform over- or under-bake; adjustable in the settings |
| Convection fan failure (Gallery) | Occasional | uneven heat that reads as a wrong temperature |
| Bake element partially failed | Occasional | element glows but puts out reduced heat |

Walking Through the Diagnosis#
Confirm the problem first with an oven thermometer, since "wrong temperature" is often a perception of uneven heat. Set the oven to 350°F, let it fully preheat, and read the thermometer at center rack after thirty minutes. If it is uniformly off by more than a small margin, start with calibration rather than parts.
To recalibrate, press Bake, then hold the Temp Up and Down arrows together for about three seconds to reach the offset setting; adjust in 5°F steps up to plus or minus 35°F, press Start to save, and re-verify at 350°F. If the oven is off by more than the 35°F the offset allows, or the error is erratic rather than uniform, the temperature sensor has likely drifted — cut power at the breaker, and on gas models shut the gas valve, then meter the sensor (316490000), which should read roughly 1,080 ohms at room temperature; a value well off that means replace it. On Gallery convection models, uneven results that feel like a temperature fault are often the convection fan not circulating air, so confirm the fan spins during a convection bake. And a bake element that glows but never brings the oven up to temperature has partially failed and needs replacing. Frigidaire's exact procedure and part fitment vary by model — for example the Gallery FGEF3036TF versus the standard FFEF3054TS — so match the sensor and steps to your unit from the serial-plate model number.
Repair or Replace? The Short Version#
None of this condemns the oven. Recalibration is free, and the temperature sensor is one of the least expensive parts in the appliance, so on a Frigidaire that otherwise heats it is clearly worth fixing rather than replacing. Even a convection fan or bake element stays well under the cost of a new range. Because a miscalibrated oven quietly ruins baking, it is worth checking the sensor and offset early — and if the reading is erratic despite a good sensor, have the control checked. book an EasyBear technician.

Frequently Asked Questions#
How do I calibrate a Frigidaire oven?#
Press Bake, then hold the Temp Up and Down arrows together for about three seconds to reach the calibration offset. Adjust in 5°F steps, up to plus or minus 35°F, and press Start to save. Verify the result with an oven thermometer at 350°F for thirty minutes before deciding anything else needs replacing.
How do I know if the temperature sensor is bad?#
Meter the sensor (Frigidaire 316490000) with the power off: at room temperature it should read roughly 1,080 ohms. A reading well off that value means it has drifted and is feeding the board a false temperature. Drift usually shows as an offset the calibration cannot fully correct, or as erratic readings.
My Frigidaire Gallery oven cooks unevenly — is that a temperature fault?#
Often it is the convection fan rather than the temperature itself. On Gallery models the fan circulates heated air, and if it stops the oven develops hot and cold spots that feel like a wrong temperature. Confirm the fan spins during a convection cycle before condemning the sensor or element.
How often should I check my oven's temperature accuracy?#
About every six months with an inexpensive oven thermometer at 350°F. If it is off by more than a modest amount, recalibrate using the Bake plus Temp-arrow offset. Catching drift early keeps baking consistent and flags a failing sensor before it gets worse.
