Just fixed a fridge for a lady who kept a log of every repair for 20 years
I was on a call last week for a noisy Whirlpool side-by-side. The customer, an older woman in a house in Tempe, handed me a small notebook. She had written down every service visit since 2004, with dates, what was fixed, and the cost. She pointed to an entry from 2011 and said, "The last guy said this fan motor would last ten years, and he was right." It was the exact same part failing now. Having that full history made finding the problem take maybe 15 minutes. Has anyone else had a customer come prepared like that, and did it actually help?
