Thanks a lot everyone for all the explanations and photos.
I struggled to remove the fridge because of these screws (see the pics attached). After lifting half the way, the fridge was stuck because of them. I had to move on each side to be able to pull it eventually.
I’ve just completed the catch assembly replacement on our T6.1. The fridge came out half way and stopped. I removed the two Phillips head screws from inside the wardrobe to release one end of the the kitchen front top extrusion. It can flex out a small amount and the fridge then came out. When the fridge was out I realised it was one of the protruding screws that was catching on the metal plate at the bottom of the fridge insulation.
Once the catch assembly was out I found it would have been very easy to replace the
Small broken spring instead of buying the whole catch assembly. I wonder if would be possible to obtain some spare springs?
As I can see this happening again, the small spring takes a lot of punishment every time you need a cold beer from the fridge.
I also removed the tips of the protruding self tapping screws with angle grinder before putting the fridge back to make it easier for next time the spring break in half.
