Diagnosing a Blown Thermal Fuse in Your Microwave
Microwaves are an essential kitchen appliance and may stop working when its thermal fuse is blown. If you are experiencing a sudden malfunction with your microwave, you should know how to easily diagnose a thermal fuse failure and determine if that is the cause of the problem.
When a microwave is heated up and the internal light is turned on, the thermal fuse will automatically turn off if the temperature goes above a certain level. If the microwave gets overly hot, it may indicate that the thermal fuse is blown and needs to be replaced. To determine if that is the case, the following steps should be taken:
- Unplug the microwave and remove the outer casing.
- Locate the thermal fuse and check that it is in one piece. If it is not, then it is likely the cause of the problem.
- Test the fuse with a multimeter to be certain that there is no electricity running to it.
- If necessary, replace the fuse with one of the same rating.
In some cases, a blown thermal fuse could be just one of several problems with a malfunctioning microwave. To get reliable results, it is best to have the appliance serviced or inspected by a professional. An experienced technician can frequently identify and fix underlying issues, potentially saving you time and money.
It is important to note that some microwave models require a professionally installed thermal fuse to be replaced. In such a situation, it is always better to trust a technician with the job.
