I've a whirlpool american fridge. About 3-4 times per hour it gives off a loud "ticking" sound for about 30 seconds.
I thought originally it was connected to the water filter (which needed to be replaced around the time that this started), but am still experiencing the problem.
We had the same problem with ours. Then there would be a loud clicking noise when you used the ice maker. Then the freezer defrosted! The problem was the control board. We bought the fridge in 2003 and it is on its 3rd Control Panel. The last one was fitted in June 2007 and the 4th is to be fitted next week sometime. Has anyone else had the same problem with the control panel?
