Possible Causes
Shorted NTC temperature sensor on heating plate, Sensor wires shorted together or to chassis, Excessive residue or burnt food on heating plate causing localized overheating, Faulty main control PCB interpreting sensor signal
How to Fix / Troubleshooting
Safety first: Unplug the cooker and let it cool completely.
- Clean the heating plate: Remove the inner pot and thoroughly clean the aluminum heating plate with a soft cloth. Remove any burnt-on food, sugar, or oil that could cause hot spots. Ensure the plate is dry before use.
- Check for pot deformation: A heavily warped or dented inner pot can cause uneven contact and overheating. Replace the Hamilton Beach inner pot if it rocks or does not sit flat.
- Inspect sensor wiring: From the underside, locate the temperature sensor on the heating plate. Check that the insulation on the wires is intact and not melted or pinched against the metal chassis. Separate any wires that appear stuck together.
- Test sensor resistance: With a multimeter, measure the NTC resistance at room temperature. A reading near 0Ω indicates a shorted sensor that must be replaced.
- Replace components: If the sensor is shorted, install a new bottom temperature sensor / NTC. If wiring and sensor are good but E2 persists, the main control PCB may be defective.
