Hi, I couldn't get the 555 in my local stores so I had to order online. If my spare time permits I am planning to get things done this weekend. Will let you know the outcome.
Thanks for getting back to this thread. I'll look forward to your assembly results, and whether it still applies to your application on the fridge.
