Common faults of rice cookers and rice cooker maintenance methods

Common troubleshooting methods for rice cooker repair:1. For automatic rice cookers, first check whether the two electrode wires connected to the heating plate are not in good contact or fall off, and then check whether the heating wire in the heating plate is broken.

Find out the fault and replace the corresponding parts. 2.Rice cookers with electronic functions should be inspected according to the first rule.

If it doesn't work, you can change to a good electronic light board. 3. Fault phenomenon: common troubleshooting methods for rice cooker maintenance:

1。Press the rice cooking switch button to power on for ten minutes, the "cooking" and "keep warm" lights are always on, and the magnetic steel switch contacts for cooking rice cannot be closed. Method: Use a blade or sandpaper to scrape off the contact oxide on the metal sheet of the magnetic steel lever and adjust the elasticity of the metal sheet.

2.The magnetic steel thermostat is magnetically aged and can be replaced. Four.

Fault phenomenon: Rice cooker maintenance common rice bottom scorching troubleshooting methods: 1.

Keep the contacts of the thermostat open and move the contacts of the thermostat bimetal away from each other.

After the smart rice cooker is powered on, all the indicators and health can be extended normally, except that there is no heat, and the heat is good, and the heating tube is energized. What went wrong, thank you.

Common fault 1: After plugging in the power plug, the electric key Lingyuan fuse is blown out.

Cause and maintenance method: It may be because of the power supply 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 dried with a hair dryer and continue to be used; It may also be due to the carbonization of the surface of the power socket and plug due to long-term use, resulting in a short circuit on the carbonization layer on the surface, which can be ground off with fine sandpaper and wiped clean with alcohol.

Common fault 2: The rice cooker does not heat.

Cause and maintenance method: the deformation of the inner pot or the deformation of the heating plate causes the temperature to be too high and causes the burning insurance, in this case, the inner pot can be carefully trimmed or replaced by the heating plate; For rice cookers with a selective switch, it may also be caused by a damaged switch, which should be replaced; It may also be because of the internal circuit break, which is just a matter of finding the open circuit and connecting it properly.

Common fault 3: Skip when the rice is not cooked.

Cause and maintenance method: This fault is generally caused by the weakening of the magnetic force of the permanent magnetic ring in the thermostat, which is the thermostat that can be disassembled to check whether the magnetic ring is broken, if the permanent magnetic ring is broken, the same model of thermostat must be replaced, if it is not broken, but the suction is weakened, then the temperature control screw on the thermostat can be adjusted, adjust a quarter of a circle each time, adjust a trial cooking rice once.

Common fault 4: Cooking paste.

Cause and maintenance method: It may be that the normally closed contacts of the insulation switch are sintered and glued together, resulting in the insulation switch continuing to energize the heating pipe after the rice is cooked, so the rice is paste, at this time, the contacts can be separated with a knife, and then the contact surface is cleaned with fine sandpaper.

Common fault 5: You can't keep warm after cooking.

Cause and maintenance method: It may be that the normally closed contact surface of the insulation switch is dirty or ablated, so that the contact resistance of the contact is too large, resulting in the contact closure circuit is not connected, and the heating element is not heated, resulting in the rice cooker can not be kept warm.

Common fault six: The rice cooker always jumps by itself.

Cause and maintenance method: It may be that the water and rice are not properly matched, that is, there is too little water, just add appropriate water.

Common fault 7: The rice cooker is powered off after heating for a period of time, and then automatically energized after a while.

Cause and maintenance method: The temperature control switch is damaged, and only need to be replaced with a new one.
