I should mention two things.
1. The fridge is 4 years old bought in Aug 2008.
2. The has been a persietent knocking or rapping knock that seems to be around 6-7 knocks in rapid sequence every so often thats been going on for at least 1 year. The knocking appears to come from the dispenser area but I'm never actually very close by when it happens so its more an educated guess on my part.
Other the the leak and the knocking its running OK.
So, any possible ideas on the cause and potential solutions that either I can do as a DIY'er or needing a tech would be much appreciated again.
Hoping its as simple as a frozen or plugged drain line, something I'll look in to soon as I download the schematics and find out where that thing is if it exists..
Again thanks for your help with me and everyone else, you folks are a tremendous resource that is a godsend for all us regular folk..
Tip of the hat.
