Hello,

I bought this transformer new 2 years ago and have used it lightly. The thermal coupling has sometimes stuck and was advised by the seller to bang it on a table as they are pretty robust!
Got it out for the festive season and completely dead. Have removed the casing by drilling the 4 plugs but cannot see anything loose. Is there a way to manually reset the coupler or any advice to get it working please?
Normally Marklin stuff lasts for years and only bought this to replace my aging blue transformer.
Advice appreciated

This transformer has two fuses that are instead of the former bimetallic one for 0-B and the other for 0-L

If one of them is burned, will it be difficult to find an adequate replacement?
It is possible to replace an external fuse of adequate strength and bypass the blower in the transformer
