How to Replace 316490000 Oven Temperature Sensor on Frigidaire Electric Range — Step-by-Step

Your Frigidaire oven is running 50 degrees hotter than the display shows, burning everything you bake. Or maybe it's the opposite — your FFEF3052TS barely reaches 300°F when set to 375°F. Nine times out of ten, you're looking at a failed temperature sensor probe. The 316490000 sensor is the component that tells your oven's control board the actual cavity temperature, and when it fails, your baking becomes a guessing game.

This repair works for Frigidaire, Kenmore, and Electrolux electric ranges including models FFEF3052TS, FGEF3036TF, LFEF3054TF, and hundreds more. One user put it perfectly: "The part came in a few days. Easy to install and the temp problem with the oven was solved." That's exactly what we're aiming for.

What You Need Before Starting

• 1/4-inch nut driver or socket wrench
• Flathead screwdriver (for wire harness clip)
• Work gloves (oven walls have sharp edges)
• Flashlight or headlamp
• Replacement 316490000 sensor probe

Repair Time: 15-20 minutes
Difficulty: Easy — No special skills needed

Safety First

Unplug your range from the wall outlet or flip the dedicated 240V breaker in your electrical panel. Electric ranges pull serious amperage, and you'll be working near live connections inside the oven cavity. If your range is hard-wired, test with a non-contact voltage tester before touching anything. The oven should be completely cool — waiting a few hours after your last bake session prevents burns from residual heat on metal surfaces.

Step 1: Remove the Oven Racks and Locate the Sensor

Pull out all oven racks so you've got clear access. The temperature sensor probe is mounted on the upper back wall of the oven cavity — it's a metal tube about 3 inches long sticking through a small bracket. On most Frigidaire models like the FGEF3059TF, it's centered horizontally and positioned about 6 inches down from the top. You'll see the probe tip exposed inside the oven, with wiring running through the back wall to the control area.

Step 2: Disconnect the Wire Harness

Open the back panel of your range by removing 4-6 screws along the edges. Some models have clips instead — just pull firmly. Once the panel's off, locate where the sensor wires connect to the main harness. There's a plastic connector clip that locks the two-wire plug in place. Press the release tab with your thumb and pull straight back. Don't yank on the wires themselves. If it's stubborn after years of heat cycling, wiggle it gently side-to-side while pulling.

Step 3: Remove the Mounting Bracket

From inside the oven cavity, you'll see the sensor held by a metal bracket with one or two hex-head screws. Use your 1/4-inch nut driver to remove these screws. The bracket might feel tight because heat expansion has basically welded it to the back panel over time. Once the screws are out, the entire sensor assembly pulls straight back through the oven wall. Keep track of any washers or spacers — you'll need them for the new sensor.

Step 4: Install the New 316490000 Sensor Probe

Feed your new sensor through the back wall from the rear of the range. The probe tip should extend about 2 inches into the oven cavity — not touching the back wall, just floating in the space where it can read air temperature accurately. Reattach the mounting bracket and tighten the screws snugly but don't overtighten. The sensor tube is relatively thin metal and can deform if you go Hulk-mode on those screws. Reconnect the wire harness until you hear the clip snap into place.

Step 5: Reassemble and Test

Replace the rear access panel, making sure no wires are pinched between the panel and the range frame. Restore power at the breaker or plug. Your display might flash or show an error code that clears after a few seconds — that's normal. Set your oven to 350°F and let it preheat. Use an oven thermometer placed on the center rack to verify accuracy. Most ranges settle within 10-15 degrees of the set temperature, which is perfectly acceptable. If you're still seeing wild swings or the symptoms haven't changed, you might be dealing with a bad control board, but that's rare.

Testing After Installation

Run a full preheat cycle and check the temperature with an independent oven thermometer. The reading should stabilize within 10 degrees of your set temp after about 15 minutes. Bake something you know well — like cookies from a mix — and watch how they brown. Even browning across the entire pan means your sensor's doing its job. If you had the "oven too hot" symptom before, you'll immediately notice your food isn't charring on the bottom anymore. For the "little to no heat when baking" issue, your oven should now actually reach and maintain the target temperature instead of cycling off prematurely.

Frequently Asked Questions

How do I know if my oven sensor is bad versus a heating element problem?

If your oven heats up but the temperature is wildly inaccurate — either way too hot or not hot enough despite elements glowing — that's the sensor. If the oven doesn't heat at all and you don't see the bake element glowing red, that's an element issue. The sensor doesn't prevent heating; it just tells the control board when to cycle the elements on and off. An easy test: set your oven to 350°F and watch if the element cycles. If it never turns on or never turns off, you've likely got a sensor sending bad data.

Will this fix the F10 or F11 error code on my Frigidaire range?

Yes, most likely. F10 and F11 codes indicate the control board is seeing an out-of-range temperature reading from the sensor — either a shorted or open circuit. The 316490000 sensor fails by developing resistance changes that throw these codes. Replacing the sensor clears these errors in about 90% of cases. If the code returns immediately after replacement, you're looking at damaged wiring or a control board fault, but start with the sensor since it's the cheapest fix.

Can I use the oven while waiting for the replacement part to arrive?

Technically yes, but it's frustrating and risky. If your sensor is reading too hot, the oven will shut off the elements early and your food will be undercooked. If it's reading too cold, the oven will overheat and potentially burn your food or even damage internal components from excessive heat. You can compensate by adjusting the temp dial — if your oven runs 50 degrees hot, set it 50 degrees lower — but that's annoying trial and error. For most people, it's worth waiting a few days for the part rather than ruining dinner.
