The gear switch of the rice cooker is the part that has the longest use and contact time during normal use, and it is also the place where the failure rate of the rice cooker is the highest and it is the easiest to break down. When using the rice cooker, lightly press the gear switch without violent operation, which can effectively prolong the service life of the switch. When the switch has poor contact, it must be replaced in time.
The dry burning temperature of the rice cooker will reach 300 to 400 degrees. Ultra-high temperature will shorten the service life of the thermostat and heating plate, and there will be the possibility of deformation of the base. Don't let the rice cooker burn empty or dry during normal use, which can effectively prolong the service life of the thermostat and the heating plate.
