Thank you for using Just Answer. I will be glad to assist you in your answer. Think about safety when doing repairs, electric, water, gas, ect.
Normally a high pitch noise is a fan motor. Can you pin point where the noise is coming from such as the fridge, freezer, back of unit....ect? Please let me know...thank you
Thank you for getting me started toward understanding what the problem might be. My fridge is in a house about 40 miles from here (I'm renovating it), so I can't tell you right now where the noise might be coming from. I'll visit the house tomorrow and see if I can pinpoint where it is originating.
I'll then provide that information to you. And I'll be happy to "bonus" if it gets me to the point where I understand if this is a 1-off defect or a fundamental flaw of the design of the fridge.
I'll follow up with you tomorrow. Thanks.
