Should I replace my Maytag Performa refrigerator? - maytag refrigerator light bulb replacement

I bought my refrigerator from Lowe's for 6 years. It was new and costs $ 400.00. It worked great until yesterday, and kept refrigerators and freezers at the top. He is 6 years the average life expectancy or should a technician? The light goes on and still hear the engine running. Thank you.
