Possible Causes
Overheating triggering thermal cutoff, Loose power cord connection at strain relief, Failing internal fuse or thermal protector, Faulty main board solder joints
How to Fix / Troubleshooting
Safety first: Unplug the cooker and allow it to cool fully before inspection.
- 1. Check ventilation: Ensure there is adequate space around the cooker and that vents are not blocked.
- 2. Inspect power cord and plug: Wiggle the cord gently at the entry point; if power cuts in and out, the cord or internal connection may be loose.
- 3. Access thermal protector (advanced): Remove the bottom cover and locate the thermal cutoff or thermostat on the heating plate. Check for signs of overheating or discoloration.
- 4. Inspect board solder joints: Look for cracked or dull solder joints on the power input and heater relay. Reflowing solder is a job for an experienced technician.
