Whirlpool Error Code F3
Shorted temperature sensor
Common Causes
- 1Sensor short
- 2Wiring issue
Step-by-Step Troubleshooting
- 1
Access the oven temperature sensor — it enters the oven cavity through the rear wall, secured by one or two screws
- 2
Disconnect the sensor and measure resistance: should be approximately 1080 ohms at room temperature (70F)
- 3
A reading significantly below 1080 ohms (under 500 ohms) confirms a shorted sensor
- 4
Inspect the sensor wire harness inside the oven cavity for insulation damage where wires contact the hot oven walls
- 5
Replace the sensor if resistance is out of specification
Pro Diagnostic Tip
The Whirlpool oven temperature sensor is an RTD (Resistance Temperature Detector) that increases resistance as temperature rises. At room temp (70F) it should read 1080 ohms, at 350F approximately 1500 ohms. F3 (shorted) and F4 (open) are opposite failures of the same sensor. On self-cleaning models, extreme heat degrades the sensor faster — expect replacement every 5-7 years.
