How to Fix / Troubleshooting
Safety first: Disconnect power at the breaker before testing components.
Steps to check:
- Verify correct sensor: Confirm that any previously replaced sensor matches the original Hotpoint part number for your model.
- Measure resistance: Test the sensor at room temperature and compare to specification (~1050–1100 Ω). Replace if out of range.
- Connector and harness: Inspect and reseat the sensor connector at both the sensor and EOC. Repair any damaged wiring.
- Control calibration: Some models allow recalibration of oven temperature in the user settings. Refer to the user manual to perform a calibration reset.
- Replace EOC: If sensor and wiring are correct and F20 persists, replace the EOC.
Tip: After repairs, verify oven temperature with an accurate oven thermometer.
