Hotpoint Oven Error Code F3
Oven sensor open
Common Causes
- 1Sensor failed open
- 2Connector loose
- 3Wire broken
Self-clean cycles stress the sensor at 900F+. If F3 appeared during or after self-clean, the sensor likely failed from thermal fatigue.
Step-by-Step Troubleshooting
- 1
Access rear of range and locate oven sensor connector
- 2
Reseat the sensor connector firmly — a loose connector is the top cause
- 3
Test sensor resistance — should read ~1080 ohms at room temp
- 4
If resistance reads open (OL/infinite), replace the sensor
Pro Diagnostic Tip
F3 (open) and shorted sensor are opposite failure modes. If you get both codes alternating, the wiring has an intermittent break — flex the harness while measuring to find the break point.
