Question

We bought a refrige from Sears two years ago. And with the first one the light in the inside stayed on so much it melted the liner. So they replaced it for free. Now with the replacement it did the same thing and we just had a repair guy come out and say it was going to cost $350 dollars to fix. There is a problem here that we did not cause and we need a solution.
