Technician named Allen came out today to service a request through Lowe's extended warranty plan. I've had 3 other technicians come out to resolve the same issue with no success (from another company). He immediately recognized the issue was and was able to replicate the sound. First tech that's come out and ACTUALLY PULLED THE FRIDGE FROM THE WALL! Novel concept apparently. He did a great job and was friendly and efficient. Also spoke with the office staff this morning about having the tech come early in the afternoon and they happily obliged. I'm very happy with my experience.
