Tenant says fridge is working, but makes a loud sound. Help!

[Katrina P.]

Hi there, fellow REIs!

I have a tenant who is complaining about her refrigerator. She says the unit is cooling properly, buy makes a LOUD, short, humming/buzzing sound every time it comes back on to cool. Of course, the biggest concern for me is that it cools her food - which it does. However, she keeps saying that she's concerned that it won't come back on at some point. I bought the unit used, & after doing some investigating, I've learned that it was purchased in 1985. So I guess it's far surpassed its life expectancy; but of course, I don't want any premature expenses. Please give me some advice on how to handle this one. Should I just replace it, try and fix it, or tell her she'll just have to deal with the noise?

Thanks, in advanced, for all responses!
