What is the role of the thermal fuse in a rice cooker?

It helps avoid further damage to the unit in case of overheating.

It helps us identify if the rice cooker is in cooking or warming mode.

It maintains the temperature at the optimum level during warm function.

It helps reduce the risk of electric shock.

The thermostat limits the temperature during warming mode by:

Disconnecting the heating element from the power source when the desired heat is reached.

Disconnecting the heating element from the power source in case of overheating.

Limiting the amount of current flowing along the heating element.

Limiting the temperature through the magnet and the metal components.

What does the statement " once the water inside the pot reaches its boiling point, the temperature will remain constant" mean?

The temperature of the water cannot increase anymore once it reaches its boiling point.

The temperature of the water will increase until the unit switches to warming mode.

The temperature of the water will decrease after it reaches its boiling point.

The temperature of the water will continue to increase after it reaches its boiling point.

What is the difference between the thermostat and the high-resistance coil?

The thermostat regulates the temperature during warming mode using the bimetallic strip while the high-resistance coil limits the current.

The thermostat regulates the temperature during warming mode by limiting the current while the high-resistance coil uses a bimetallic strip.

The thermostat regulates the temperature during the cooking mode by limiting the current while the high-resistance coil uses a bimetallic strip.

The thermostat regulates the temperature during cooking mode using the bimetallic strip while the high resistance coil limits the current.

Why is it not possible to set the rice cooker to cooking mode without the pan placed inside?

Because the pan must press down the center thermostat for the magnet and the metal to overcome the force of the spring.

Because the pan triggers the cooking mode switch.

Because the pan serves as the current path during the cooking mode.

Because the switch lever pushes the metal and the magnet of the center thermostat apart.

What safety precaution should you observe in repairing a rice cooker?

Make sure the unit is turned off, unplugged from the power source, and let it cool down before performing any repairs.

Which evaporation test result indicates a good rice cooker?

The rice cooker turns off 1 minute before and after steam generation comes to a stop.

The rice cooker turns on 1 minute before and after steam generation comes to a stop.

The rice cooker turns off 1 minute after steam generation comes to a stop.

The rice cooker turns off 1 minute before steam generation comes to a stop.

How would you troubleshoot a rice cooker with cooking function failure, but the cooking indicator is turned on?

Check the heating element for resistance, then replace if found defective.

Check switch lever adjustment, then adjust if necessary.

Check the continuity of the heating element, then repair if found defective.

Check the continuity of the thermal fuse, then replace if necessary.

What is the proper procedure in troubleshooting a rice cooker that burns or overcooks rice?

Check the center thermostat, then replace it if found defective; if good, check if the switch lever is properly adjusted, then adjust it as needed.

Check the thermal fuse for continuity, replace it if found defective; if good, check if the switch lever is properly adjusted, then adjust it as needed.

Check the thermal fuse for continuity, replace it if found defective, if good, check if the switch is properly adjusted, then adjust it as needed.

Check the center thermostat; replace it if found defective; if good, check if the switch button is properly adjusted, then adjust it as needed.

While diagnosing a rice cooker that switches to warming mode too early, you find out that the center thermostat is in good condition and the switch lever is properly adjusted. What could be the possible cause of the problem?

Poor contact between the pan and the sheathed heater.

Defective thermal fuse due to overheating.

Insufficient supply of current along the heating element.

Microswitch contact is dirty, rusty, or corroded.

What should be done first in performing component replacement procedure?

Determine the description and ratings of the individual defective parts.

Install the replacement parts and other components correctly.

Disconnect or remove the electrical and mechanical parts.

Identify the sources of the replacement components.

Why should you not use abrasive materials in cleaning a rice cooker?

Because it may scratch the non-stick coating and the body.

Because it contains toxic materials.

Because it may increase the risk of contamination.

Because it may damage the internal components of the rice cooker.
