My microwave use ceramic line fuse 20A 250V Can I use any ceramic fuse if rating is the same even if it is not a line fuse or do I need to use a line fuse?
Hi @k1love As long as the rating is the same i.e. same volts and amps, that it is a ceramic fuse and that it fits securely into the fuse holder, it will be OK . If you want the manufacturer’s recommended replacement fuse, search online for WB27X10928 to find suppliers of the fuse that suits you best. There is always a reason why a fuse has blown so perhaps get 2 or 3 just in case you haven’t found the reason why the fuse blew as it may happen again soon after you replace it. Be safety aware when working in a microwave oven. The HV capacitor in the oven can store >6000V DC for months even if the power has been disconnected for this length of time. This amount of voltage can seriously injure you. The HV capacitor needs to be correctly discharged as soon as it can be accessed after the microwave’s cover has been removed and before commencing any further work inside the oven.
