When we bought our current fridge, I forget how many years ago, it crapped out within two days of being installed/delivered. They have a sealed system so not like a car where you can easily connect etc.
Tech came out and did exactly as you described. I was upset that our system was no longer 'sealed' at the factory but he assured me it would work just fine.
So far so good. Knock on wood. It probably is as old as yours is Glen, if not older. They don't make them like they used to.
