I. After the temperature fuse is damaged, the components with the same specifications or similar characteristics should usually be replaced. Generally, the appearance of the thermal fuse is marked, and the mark must be clearly seen before replacement, so as to purchase suitable accessories. However, practice shows that enthusiasts often use ordinary fuses or resistors instead of them because there are no replacement parts for the time being, and some simply omit them and directly short-circuit the temperature fuses. If ordinary fuse or resistor is installed, there is no overheat protection. If the temperature fuse is shorted directly, the overcurrent protection will be lost.
These practices are definitely wrong, which may lead to accidents such as failures, parts damage and even fires, and the losses are likely to be enormous. In recent years, we often read in newspapers and other media news reports about fires caused by malfunctions or improper use of small household appliances such as rice cookers. Most of the losses are great, so we should not treat them lightly. Temperature fuses are usually not replaced by other components, but when purchasing the original model devices, they can be replaced by temperature fuses of different models with similar or identical main specifications and parameters.
Second, the temperature fuse is usually sheathed with a high-temperature resistant plastic sleeve, and then installed on the heating element or metal base of small household appliances with a metal bracket or spring steel plate. When disassembling, it can be disassembled only by unscrewing the fixing screw, and then the insulating sleeve on the temperature fuse can be withdrawn, so that the equipment can be inspected or replaced. When disassembling and assembling some temperature fuses clamped and installed by spring steel plates, they often feel that the clamping is very tight and it is not easy to disassemble and assemble.
At this time, you should be patient and look at the proper disassembly and assembly direction before operating. If necessary, you can use awls or pliers, but don't pry or dial indiscriminately, which may easily damage other parts. When reinstalling, first set the high-temperature resistant sleeve, then set the bracket or reed, and then fix it in the original position. It should be noted that it should be installed in the original position as accurately as possible and cannot be changed at will, otherwise it may weaken or lose the protection effect and even cause other faults.
Iii. the temperature fuse is usually connected with the power cord by clamping or spot welding. Unless it is damaged, generally do not cut off the connection for measurement, so as not to increase the trouble of reconnection. If the damage needs to be replaced, clamped or spot welded nconditionally, you can go to the electrical shop to buy an electrical white magnetic connector for connection; You can also cut off the original first, then separately splice the two leads of the new part and the two leads of the original, and then tin the splicing area.
It should be noted that there is less tin, and no extra solder drips.
