Possible Causes
Weak or partially open bake element, Faulty oven temperature sensor, Poor door gasket seal causing heat loss, Calibration error in electronic oven control
How to Fix / Troubleshooting
Safety first: Disconnect power before testing components.
- Verify with thermometer: Place an oven thermometer in the center of the oven and compare actual temperature to the set temperature after preheat. Note any consistent offset.
- Inspect bake element: Look for cold spots or uneven glow when heating. Test resistance; replace if high resistance or intermittent.
- Check door gasket: Inspect the door seal for gaps, tears, or flattening. Close the door on a sheet of paper; if it pulls out easily all around, replace the gasket.
- Test sensor: Measure sensor resistance at room temperature (~1050–1100 Ω). Replace if out of range.
- Calibrate control: Many Stoves electronic controls allow temperature calibration (offset) in the user settings. Adjust according to the user manual if the oven is consistently off by a small amount (e.g., ±15°C).
