Recently my fridge started making a loud click, followed by buzzing, and ending with a loud click. After some research I thought this was due to the start relay/overload capacitor so I replaced it. Subsequently, the click is now gone but the buzzing is still present. If I had to guess the buzzing is the result of failed attempts of the compressor to star, but I don't know. The fridge continues to operate "normally" and we haven't had any noticeable loss of temperature. Does this mean my compressor is going out? Thoughts? Thanks so much in advance.
