It safeguards the high voltage circuit by breaking the circuit during faults, preventing damage to key components like the magnetron. Compatible across multiple brands, it enables cost-effective repairs by replacing just the glass tube, but must be installed by experienced personnel due to high voltage risks. ## Description Replacement type high voltage fuse tube for modern microwave ovens. This high voltage fuse is wired in series with the high voltage feed from the high voltage transformer to the magnetron. The fuse will fail if there is a fault in the high voltage circuit. Such a fault could be a short circuit magnetron or a short circuit high voltage rectifier. In our experience however this fuse commonly fails for no apparent reason. The fuse just gets stressed everytime the magnetron starts which eventually leads to the demise of the fuse. The fuse however may also fail if the microwave cooking cycle is started with no food or metal objects in the oven cavity. The fuse can be replaced as a complete holder assembly though in this case the glass tube only is offered. This will alow a cheaper and equally as effective repair. In most instances the glass tube can simply be pulled from the end caps of the fuse holder. Please refer to the photographs in this listing.The fuse holder is opened by twisting each end in opposite directions. Some high voltage fuse assemblies are smaller and rectangular in shape but in most cases after clipping apart a fuse tube, as shown here, is fitted inside. It is not relevant if your fuse tube does not have the coiled spring inside as ours do.This type of fuse is fitted to many brands of microwaves and this particular type of fuse is suitable for replacement in any brand. Check the rating of the original fuse and replace with the correct value. To fit this fuse it is necessary to remove the outer casing so replacement should only be attempted by those who have experience in the repair of electrical appliances. High voltages are present in a microwave oven and it is important that the appliance is disconnected from the mains before any servicing work is carried out.
