Whirlpool Oven F3 E0 Error Code — What It Means
F3 E0 means the oven control sees an open circuit in the temperature sensing system. The oven temperature sensor, called an RTD, has lost continuity or its wiring has broken.
Whirlpool notes the problem can be the sensor, the control, or the wiring between them. A healthy sensor reads around 1080 ohms at 70 degrees F, so testing it tells you fast whether the part has failed.
Common Causes
- Open oven temperature sensor The RTD element has gone open circuit, which is the most common reason for F3 E0.
- Broken sensor wiring A wire from the sensor to the control can break or burn open, especially near the hot rear wall.
- Loose sensor connector The plug behind the rear panel can back out and break the circuit.
- Damaged harness from heat Years of oven heat can crack insulation and open a conductor in the sensor harness.
- Failed control board Less often the control itself cannot read a good sensor and posts F3 E0.
Step-by-Step Fix
- Cut power at the breaker for one minute, then restore it to clear a one-time trip.
- If the code returns, pull the oven out and remove the rear panel to reach the sensor connector.
- Unplug the sensor and set a meter to ohms across its two terminals.
- Read the resistance. A good sensor measures about 1080 ohms at room temperature.
- Replace the oven temperature sensor if it reads open or far from 1080 ohms.
- Inspect the harness and connector for burned or loose pins and repair as needed.
- Reassemble, restore power, and confirm the oven heats without the code.
Parts Often Needed
| Part | Notes |
|---|---|
| Whirlpool oven temperature sensor (RTD) | Amazon | Should read near 1080 ohms at 70 degrees F, sold by model number. |
| Oven sensor wire harness | Amazon | Replace if the wiring is burned, brittle, or broken at the connector. |
When to Call a Pro
If the sensor reads correct but F3 E0 stays, the fault is in the wiring or control board. A technician can trace the circuit and confirm which part to replace.
