Amana refridgerator

Question

i live in harvey, la... after katrina i had to replace my refridgerator. i bought an amana bottom freezer fridge... so far the fan that blows air to the refridgerator has gone out... it was covered under warranty since it was just past the time and the repair man said they used cheap plastic fans from the factory at that time... now the water has stopped in the dispencer and the ice maker... i replaced the filter... which i didn't think was the problem... and as it turns out...it isn't... seems the pump that moves water is either bad or clogged... where is the pump...i have not pulled out the fridge to search for it yet and is it easy to get the part??? any help would be greatly appreciated... this refridgerater is less than 3 yrs old.....thanks... kirk
