    • Check the code on the Fuse: it is "T1A L250V". Explanation can be found on this page: https://www.swe-check.com.au/pages/learn...

    • The new fuse must have similar properties to ensure a safe operation. Otherwise the risk of fire occurs due to high currents.

    • The new fuse can be easily put into the holding metals with the pliers

    • Put on the cover again and fix the screws
