7 Common Faults and Maintenance Methods of Electric Rice Cooker

Fault 1: When the power is plugged in, the fuse immediately melts
Reason and repair method:
1. There is water or rice soup in the power socket of the rice cooker, causing a short circuit. The water in the socket can be sucked out with a tissue, then dried with cold air from a hair dryer, and then reused with the socket.
2. The power socket or plug of the rice cooker is short circuited due to surface carbonization due to prolonged use. The carbide layer on the surface can be lightly ground with fine sandpaper and then wiped dry with alcohol.
Fault 2: No power supply
Reason and repair method:
1. If the insurance is burned out, replace it.
2. There is a problem with the circuit, please check the circuit.
Fault 3: The insulation light is on and the cooking light does not turn on
Reason and repair method:
1. The heating plate is not heating, which may be due to poor power cord. Check the circuit.
2. If the heating plate is not heated, it may also be due to the metal plate switch being oxidized by fire, and the oxidized part in contact may be ground off with sandpaper.
Fault 4: Unable to cook
Reason and repair method:
1. The power cord has been turned on. Please use the ohm block of a multimeter to check the wire.
2. Current limiting resistor fuse. At this point, the resistance can be checked using the ohmic gear of a multimeter.
3. The heating tube is burnt out, and the electric rice cooker without a current limiting resistor has been working for a long time, resulting in the heating tube breaking.
At this point, use the ohmic block of a multimeter to check the heating tube. If the circuit is broken, it must be replaced with a heating plate.
Fault 5: Rice cooker
Reason and repair method:
Due to prolonged overload or water intake, the normal closing contacts of the insulation switch are sintered and stuck together. Although the rice has already been cooked and the temperature limiter has jumped down, the insulation switch continues to power the heating tube and continues to heat, causing the pot to burn.
2. The tripping temperature of magnetic steel is not good, and the tripping temperature of magnetic steel for different sizes of pots varies. For example, 700 W and 2500 W magnetic steel are easy to stick and match the corresponding magnetic steel.
3. Due to heat transfer, heat dissipation, and other reasons, iron pots are prone to sticking, rusting, and sand holes. It is best not to choose a heavy looking iron pot liner.
Fault 6: Boiled and mixed with raw rice
Reason and repair method:
1. The rice water ratio is incorrect, there is less water. Adjust the rice water ratio and try again.
This is usually caused by the weakening of the magnetic force of the permanent magnet ring in the temperature limiter. At this point, the temperature limiter of the rice cooker can be removed to check if the magnetic ring is broken.
3. If there are foreign objects on the bottom of the pot and heating plate, remove them.
Fault 7: Cooking time too long
Reason and repair method:
Using a multimeter, check if one set of heating tubes in the heating plate is burnt out. If there is a problem with the hot disk, please replace it with a new one.
