However, it is definitely not cost-effective to maintain such a rice cooker. Its maintenance cost can even exceed the price of a rice cooker, so it is more appropriate to buy a new one.

You can also try to fix it yourself. The steps are as follows:

Fault 1: As soon as the power supply is plugged in, the fuse will blow out immediately. Reasons and maintenance methods:

1, short circuit caused by water or rice soup in the power socket of the rice cooker. In this case, the water in the socket can be sucked out with a paper towel, and then the socket can be dried by the cold air of a hair dryer for reuse;

2. The power socket or plug of the rice cooker has been used for too long, and the surface carbonization leads to short circuit. In this case, the carbonized layer on the surface can be gently ground off with fine sandpaper, then cleaned with alcohol and dried.

Fault 2: Reasons for power failure and maintenance methods:

1, the safety is burnt out. Insurance replacement (300W- 1000W means 10A insurance, 1600W-3950W means 15A, 20A insurance or replacement of connecting wires);

2. There is something wrong with the line. Check the wiring.

Fault 3: the heat preservation light is on, but the cooking light is not on. Reasons and maintenance methods:

1, the heating plate is not heating, and the power cord may be broken. Check the line;

2. The heating plate does not generate heat, or the contact of the metal switch may be ignited and oxidized. Use sandpaper or small file to polish off the oxidized part of the contact;

3. The heating plate is hot. Check the lamp plate. If it is broken, replace it with a new one.
