[6] Automatic heat preservation rice cookers often cook, and one of the important reasons is that the contacts of their bimetallic thermostats stick together. The treatment method is as follows: firstly, remove the two copper leads from the contacts of the bimetallic thermostat, then remove the thermostat from the base, pass between the two contacts with a sharp knife, and polish the two contacts smoothly and brightly in turn. When repairing components, tighten the fixing screws to facilitate heat conduction. When cooking, press the automatic switch first, and then plug it in.
