What are thermal fuses?
Thermal fuses are a safety device installed in electrical equipment that are designed to interrupt the circuit if the temperature rises to a dangerous level. Heat -producing devices such as stoves, microwaves and hair dryers have often thermal fuses and can also be installed in a number of other electrical circuits such as light switches. These devices are usually determined as a failure that kicks in a place when other electrical safety measures are not operated, such as circuit breakers. When the component is activated, the circuit is open open, which prevents power from being powering. Thermal fuses are a single use device, which means that they need to be replaced after activation, and should never be replaced without finding that the fuse has failed. This may require that the repair services to explore the equipment to solve the problem and in some cases it may be time to completely destroy the device.
If the thermal fuse fails, in addition to examining the device, looking for problems that could lead to overheating, it may be appropriate to explore the circuit to which the device is connected. For example, an electrical problem when connecting the house could cause overheating of the device without burning the circuit breakers, and the problem could develop more serious if it is not solved. If appliances connected to the same circuit repeatedly fail, it indicates that there is a problem with the circuit, not with appliances.
The replacement of thermal fuses is generally very easy, most of the hardware stores supply a number of thermal fuses for this purpose and can be clearly seen in the wiring for the device. For people who are not satisfied with the electrical work, it is good to ask the electricians to do the job, as it can also check the equipment and replace the thermal fuse. As always when working with electric components, people should make sure that the circuit power supply, nAnd that they work are interrupted during work.
The alternative to the thermal fuse known as the thermal switch or thermal resetting is designed for multiple uses. In this case, the device opens the circuit when the temperature is too high and closes when the temperature drops back down. Some types of circuits can naturally warm up, which will have a thermal switch more useful as a safety device.
