Possible Causes
Shorted main heating element under the pot, Damaged insulation on heater leads touching chassis, Faulty triac or relay on main PCB driving the heater
How to Fix / Troubleshooting
Safety first: Immediately unplug the cooker. Do not use it again until inspected. Risk of electric shock and fire.
- Visual inspection: Remove the bottom cover and inspect the circular heating element and its wiring. Look for burn marks, melted insulation, or signs of arcing.
- Check heater resistance: Disconnect the heater leads from the board and measure resistance with a multimeter. Compare with typical values (often 20–60 Ω depending on model). A very low resistance or visible short to chassis indicates a failed heater.
- Inspect control board: Examine the PCB area around the heater triac/relay for burns or cracked solder joints.
- Replace faulty parts: Replace the heating element assembly if shorted. If the heater is fine but the triac/relay is damaged, the main PCB should be repaired or replaced by a qualified technician.
Due to mains voltage exposure, this repair is recommended for professionals only.
