We have a 20 year old sub zero 550 that is VERY loud. What

Resolved Question:

We have a 20 year old sub zero 550 that is VERY loud. What do you think the problem may be and would it be better to fix or replace? Have we maxed the life span of this unit?

The line to the ice maker broke earlier this year and we chose not to fix that.

Hi,Welcome to Just Answer, My name is XXXXX XXXXX forward to helping you today.

is it the compressor thats loud ? or does it sound like a fan? if its the compressor your better off replacing the refrigerator. the biggest problem with this unit is getting parts. i just pulled up the parts list and most of the parts are no longer available. you would need a service tech to see what the issue is and then see if the parts available. 20 years is about all you'll get out of these so it may be time for a new one. hope this helps, thanks Bryan

if someone did have one your probably looking at between $800-$1000 plus the labor and freon recharge. this could run you upwards of $2000.00 or more. you may want to start looking at new ones.
