My unit seems to knock more and more as times goes on. it is less than 2 years old and has always knock but now knocks more and more and getting louder. the knocking can range from 5 sec to 20 sec long and does it about every 10 minutes. there is no temp problems with the refer or the freezer, no water leaking just noisy.
any suggestions
If it is making this knocking noise when the compressor shuts off, like a clunk, clunk clunk sound... then you need to clean the coils under you unit. but if you got this after 2006, then it probably only has a 1 year warranty on the compressor. it most likely is a broken spring inside the compressor and cant be replaced without replacing the compressor.
check your warranty papers and see if it has an extended warranty, if not then call amana/ whirlpool as they own amana now, and ask if they will help you with the cost of repairs.
this unit is too new to throw away but if you have to pay for the repairs, then you might be better off replacing the unit.
dont throw it away, as it wont stop cooling but is very annoying when it shuts off. it would be a great second unit in the garage or basement if you cant get it fixed for free.
Sounds like the compressor vibration dampers are wearing out. the dampers are the rubber washers that seperate the compressor from the chassis of the fridge. when they start to deteriorate, and the compressor kicks on, it will bounce against something in the chassis, causing a knocking noise.
The knocking noise is a normal refrigerant noise that occurs when the unit starts up. unfortunatley theres not much you can do to quiet it down,
