Can I keep running the equipment with this fault active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

What part is most commonly replaced for Frigidaire Oven Temperature Sensor (RTD Probe) Replacement?

The most frequently replaced parts for Frigidaire Oven Temperature Sensor (RTD Probe) Replacement are listed in the Parts Reference section of this guide with OEM part numbers and typical price ranges. Check the table for direct replacements.

Is Frigidaire Oven Temperature Sensor (RTD Probe) Replacement a DIY repair or do I need a technician?

Sensor swaps, fan motor replacements, and condenser cleaning are typical DIY-level repairs. Anything involving refrigerant, gas, or high-voltage (>240V) work requires a licensed technician for both safety and code-compliance reasons.

Q: What does Frigidaire Oven Temperature Sensor (RTD Probe) Replacement mean?

Erratic oven temps, undercooked food, or error codes mean your RTD sensor is bad. Replacing the oven temperature probe fixes inconsistent heating and restores accurate control.

Q: How do I fix Frigidaire Oven Temperature Sensor (RTD Probe) Replacement?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Frigidaire Oven Temperature Sensor (RTD Probe) Replacement — What This Part Does

The oven temperature sensor (also called an RTD probe or sensor thermistor) sends a resistance signal to the control board so the oven knows the actual cavity temperature and can cycle the heating elements correctly. Frigidaire uses this sensor for precise temperature regulation during baking and roasting.

The sensor fails when the internal resistance element degrades, gets contaminated, or breaks open. Damaged wiring, corroded connectors, and poor splice joints also cause temperature-sensing circuit problems. When the sensor reads out of range or intermittent, the control can’t regulate heat properly and you get inconsistent cooking performance or error codes.

Signs It Needs Replacing

Oven temperature is way off or fluctuates during baking Food burns, undercooks, or cooks unevenly because the sensor is sending a bad resistance reading and the control can’t hold the setpoint.
Error codes or flashing display related to temperature The control detects an out-of-range or open sensor circuit and posts a fault code or disables the oven.
Oven won’t heat at all or shuts off early A shorted or open sensor tells the control that the oven is too hot or that no sensor is present, so heating is disabled.
Oven takes much longer to preheat than normal The sensor is reading low so the control thinks the cavity is colder than it is and keeps calling for heat past the actual setpoint.
Oven runs too hot and burns food on the edges The sensor is reading high so the control thinks the oven is cooler and continues to apply full power.
Sensor measures wrong resistance at room temperature With power off and the sensor disconnected, a multimeter reads significantly different from the expected value (about 540 ohms at room temp for some Frigidaire models, or around 1,080 ohms for others).

How to Replace It

Unplug the range or turn off the circuit breaker and the gas shutoff valve if you have a gas model.
Pull the range forward away from the wall so you can access the rear panel.
Remove the screws holding the rear access panel and lift it off to expose the back of the oven cavity and wiring.
Locate the temperature sensor probe (a metal tube sticking through the rear oven wall) and follow its lead to the wire connector.
Disconnect the sensor connector from the oven harness and use a multimeter set to ohms to measure resistance across the sensor terminals (expect approximately 540 ohms at room temperature for many Frigidaire models, though some read around 1,080 ohms).
If the reading is way off or open, unscrew the single retaining screw or bracket holding the sensor to the oven wall and gently pull the probe out of the mounting hole.
Insert the new OEM sensor probe through the same hole from the back, secure it with the retaining screw, and route the lead so it won’t pinch when you reinstall the panel.
Reconnect the sensor plug to the oven harness (some replacement sensors require you to cut the old connector off and splice it onto the new sensor leads using butt connectors, so match wire colors carefully).
Reinstall the rear panel, push the range back into place, restore power and gas, run a test bake cycle at 350°F for 20 minutes, and verify the oven holds temperature without error codes.

When to Call a Pro

If you measure the sensor and it reads correct resistance at room temperature but the oven still won’t regulate temperature or posts error codes, the control board or wiring harness may be at fault and a technician with a wiring diagram and board-level diagnostics is your next step. On gas ranges, if you smell gas during testing or are not confident working near gas connections, call a pro to handle the repair and perform a leak check. If the sensor replacement requires cutting and splicing wires and you’re not comfortable with electrical connections, a service tech can install the new probe and make sure the splice is solid and insulated. For gas line, burner, or igniter work, or if you ever smell gas, stop and call a licensed technician.
