PROCEDURE

Check the Power Source: Ensure that the rice cooker is properly plugged into a functioning power outlet.
1 Inspect the Power Cord: Look for visible damage such as fraying, twisting, or breaks. You can use a multimeter
to check for current flow. If there’s no current, the power cord is faulty and needs to be replaced.

2 Test the Switch: Use a multimeter to check if the switch is working correctly. If the switch is faulty, it will need
to be replaced.
3 Examine the Heating Element : Unplug the appliance and let it cool. Remove the outer covering and locate the
heating element at the base of the rice cooker. If it doesn’t heat up, it may be damaged and need replacement.

4 Check the Temperature Sensor : This sensor monitors the temperature inside the rice cooker and sends this
information to the control circuit. If it’s faulty, it will need to be replaced.

5 Inspect the Control Circuit : This circuit controls the power supply to the heating element based on the
information it receives from the temperature sensor. If it’s not functioning correctly, it will need to be repaired
or replaced.
6 Look for a Blown Thermal Fuse : The fuse is a protective device that ensures user and appliance safety. If
it’s blown, it will need to be replaced.
