The F3E2 error on your GE Oven means the control board has detected a problem with the oven temperature sensor (RTD probe) circuit. Most of the time this is fixed by checking the sensor and its wiring, or replacing the sensor if it has failed.

Error code F3E2
Meaning Oven temperature sensor (RTD) circuit is open, shorted, or reading outside the normal range
Severity Medium — the oven will usually disable heating or shut off until the fault clears
Time to fix 15–40 minutes
Tools needed Multimeter, screwdriver

What the F3E2 error means

GE ovens use a temperature sensor (also called an RTD probe) mounted at the back of the oven cavity to send temperature readings to the control board. The F3E2 code appears when the board receives a signal from this sensor that falls outside the expected resistance range, which usually points to a wiring fault, a loose connection, or a failed sensor.

When this happens, the oven control typically locks out the heating elements as a safety measure and displays the error on the front panel, sometimes with a beep.

Common causes

  • Faulty or degraded oven temperature sensor (RTD probe)
  • Loose, corroded, or disconnected wiring at the sensor connector
  • Sensor probe touching the oven wall, causing inaccurate readings
  • Damaged wiring harness from heat exposure over time
  • Failed control board (less common, but possible if the sensor tests normal)
  • Moisture or food debris interfering with the sensor connection

How to fix the F3E2 error

  1. Power down the oven: Turn off power at the breaker for at least 1 minute, then restore it to see if the code clears on its own.
  2. Inspect the sensor probe: Open the oven and check that the RTD probe, usually at the back wall, is not touching the oven wall or damaged.
  3. Check the wiring connection: Access the rear of the oven and confirm the sensor’s wire harness is firmly connected with no corrosion or fraying.
  4. Test the sensor with a multimeter: A working GE oven sensor typically reads around 1,080 ohms at room temperature; consult your model’s manual for exact specs. Replace it if the reading is off or shows no continuity.
  5. Replace the sensor if faulty: Order the correct RTD probe for your model number and swap it in, making sure the connector clicks in fully.
  6. Call a technician if the error persists: If the sensor and wiring both test fine, the control board itself may need replacing, which is best handled by a qualified appliance repair professional.

FAQ

Can I keep using my oven if it shows F3E2?
It’s best not to. The oven may cut off heating unexpectedly or cook inaccurately, so it’s safer to power it down until the sensor is checked.

Is the oven temperature sensor expensive to replace?
No, sensors are generally an inexpensive part and a straightforward DIY repair if you’re comfortable working with basic hand tools and a multimeter.

Does F3E2 mean the same thing as F3 on older GE ovens?
They’re related — both point to the oven temperature sensor circuit, but the E2 sub-code gives more specific detail used in newer GE control boards for diagnostics.
