I detailed my experience with an out-of-factory-warranty refrigerator repair last month and posted it here.

TLDR: Use the Maine AG's office and submit an on-line complaint. That set the wheels in motion the very next day and my refrigerator was repaired free of charge within a few days. The repair would have cost $800 if I hadn't forced the issue through them.

The person I spoke with at the AG's office was friendly and genuinely interested in getting my problem solved. He even followed up a few weeks later to see if I'd reached a satisfactory resolution with the manufacturer.
