F3E3 — Oven Temperature Sensor Fault

F3E3 indicates a problem with the oven temperature sensor (RTD) or its associated wiring — the control reads it open or out of range. (Whirlpool does not scope F3E3 to a specific secondary cavity or warming drawer.)

How to fix it

  1. Kill power at the breaker.
  2. Access the back of the affected cavity and locate its temperature sensor connector.
  3. Measure the sensor: ~1080 ohms at room temperature is good; open or near-zero means replace.
  4. Inspect the harness from the sensor to the control for damage and repair as needed.
  5. Replace the sensor if out of spec, restore power, and run a heat test on that cavity.
  6. If F3E3 returns with a known-good sensor and harness, replace the electronic oven control board.

Why it happens

Typical signs: F3E3 on display · Warming drawer or lower oven won't reach temperature · Main upper oven may still work normally

  • Failed temperature sensor in the affected cavity RTD reads out of spec (not ~1080 ohms at room temperature).
  • Broken or shorted sensor harness Wire pinched behind the cavity or melted against an element bracket.
  • Failed control board input for that cavity Less common, but the EOC's secondary sensor channel can fail.
