Multi-meter judging good or bad thermostat
There are many types of thermostats. I don't know what kind of thermostats you are talking about. First of all, it is necessary to determine which kind of thermostats are broken. The measurement methods are basically the same. They all use a multimeter to judge whether they are good or bad. For example, the thermostat of an electric rice cooker has two contacts that are connected after being electrified. Only when the temperature reaches the set value, the contacts are disconnected to protect the furnace plate from heating. If it is the thermostat of refrigerator and freezer, it can be turned on by adjusting it to more than 1 gear after power-on. The thermostats of refrigerator and freezer are all mechanical thermostats, with 1-7 gear, 0 gear is off, 1-4 gear is refrigeration gear, and 5-7 gear is strong cold gear. If it hits strong cold gear, the refrigerator will be in a non-stop state, and it will cost electricity to run all the time. Generally, the larger the number, the lower the temperature of the freezer will be. When the temperature is low in winter, you should set the temperature at a high point to make the refrigerator stop for a long time. In summer, because of the high temperature, in order to prevent the food in the box from deteriorating, you should adjust the thermostat to a low level and let the refrigerator press work more and rest less, so as to achieve the best refrigeration effect. Generally, the temperature of the refrigerating room is between 0 and 10, and it will stop when the temperature of the freezing room reaches below MINUS 18 degrees, which is considered good; For example, under normal circumstances, the two ends of the thermostat of a water dispenser are connected, and only when the temperature reaches 85-95 degrees, it will be disconnected, cutting off the power supply and protecting the heater from heating; The thermostat of the footbath is the same as that of the water dispenser. For example, the thermostat of the electric heater is also turned off when the temperature reaches the set value, but it is better to use more than 16A250. For example, the thermostat of gas water heater is 85 degrees 10A250V, just like the thermostat of water dispenser.
