7 Trace the Circuit : Follow the path of electricity from the power source, through the switch and heating element,
to the control circuit. This will help you identify any breaks in the circuit that could be causing problems.
8 Rectify Simulated Faults : Once you’ve identified the faulty components, replace or repair them as necessary.
Always ensure the appliance is unplugged before attempting any repairs.
Remember, if you’re not comfortable performing these tests and repairs yourself, it’s best to consult with a
professional appliance repair technician.

Check the Power Source: Ensure that the rice cooker is properly plugged into a functioning power
1
outlet.
Inspect the Power Cord: Look for visible damage such as fraying, twisting, or breaks. Use a
2 multimeter to check for current flow. If there’s no current, the power cord is faulty and needs to be
replaced.
Test the Switch: Use a multimeter to check if the switch is working correctly. If the switch is faulty, it
3
will need to be replaced.
Examine the Heating Element: Unplug the appliance and let it cool. Remove the outer covering
4 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.

Check the Temperature Sensor: This sensor monitors the temperature inside the rice cooker and
5
sends this information to the control circuit. If it’s faulty, it will need to be replaced.
Inspect the Control Circuit: This circuit controls the power supply to the heating element based on
6 the information it receives from the temperature sensor. If it’s not functioning correctly, it will need to
be repaired or replaced.

Look for a Blown Thermal Fuse: The fuse is a protective device that ensures user and appliance
7
safety. If it’s blown, it will need to be replaced.
Trace the Circuit: Follow the path of electricity from the power source, through the switch and
8 heating element, to the control circuit. This will help you identify any breaks in the circuit that could
be causing problems

Rectify Simulated Faults: Once you’ve identified the faulty components, replace or repair them as
9
necessary. Always ensure the appliance is unplugged before attempting any repairs.

RESULT : Thus, the all faulty components of electric rice cooker replace successfully.
