Appliance Doctor

I had a noise and vibration issue with my dryer and called Appliance Doctor who sent out a service technician , of course dryer refused to make the noise while he was there but he spent an hourt taking it apart and in the end showed me a heat element that was defective, I didn't pay much attention to it and told him to replace it assuming that this would fix the problem. A few days later I used the dryer and after 20 minutes the noise and vibration resumed. It got me thinking about the replaced heat element and after examination realized that there was nothing wrong with the part. I called the service and explained the situation and requested another technician be sent as the first technician did not fix the problem and replaced a perfectly good part for no reason that I could see. I wanted them to send a different tech that would be unbiased to look at the replaced part and to fix the original problem. Sending the first tech to me would have been unproductive. I also felt that the tech simply replaced a part in order to pad the bill. They offered to have the first tech come back and remove the replacement part and return the cost of the part but refused to send a different tech. I decided to eat the cost of the service call and hire a different company; as a small business owner myself I would have placed my customer's needs first and sent another tech to see for myself if my customer's fears were justified.
