microwave fuse access problem

Hi @capncluster1 ,

Here’s an image showing the location of the fuse in your microwave oven.

There is always a reason why a fuse has blown so the reason for this will have to be found as you may find that if the circuit is not tested as to why this may have happened that when the fuse is replaced it will blow again.

It may be faulty or loose door interlock switches, a faulty HV transformer or perhaps a wiring breakdown. These are just some of the more obvious things to check as it may be something else entirely.

Here’s a link to the wiring diagram which may help.

Be safety aware when working inside a microwave oven. The HV capacitor 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 cover from the oven has been removed and before any further work is done inside the oven. If you don’t know what you’re doing, then don’t do it! It’s not worth it.
