Buzzing sound coming from switching relay?

I have a customer whose R845A (its pretty old) makes a loud buzzing sound. What is the cause of it? Does it need to be changed or is it fine this way?
It is causing the pump to run on a call for heat like it is suppossed to.
Thanks
Joe

The noise will probably only get worse. There is a way to clean the contacting surface that makes that noise, but you are best to just replace it0
