Hi

I have a Kenmore side by side refrigerator. We have had it since 5 years. In these 5 years we have had problems with it at least twice with very expensive repair costs. Now, though the fridge is working properly(meaning cooling and freezing) it is very noisy. Every time it turns on the loud noise starts and stops when the thermostat reaches the right temperature.
Even though it is working fine I think there is a problem imminent.
Any suggestions as to what the noise is about?

Thanks

Where is the noise coming from?
