The interior light on our refrigerator was half as bright as normal. Sam looked at the situation and determined that it was the control panel. An $800 part. He told us that if we didn't mind the dimmed light he would recommend not replacing the panel due to the expense. He also let us know under what other circumstances replacing the panel would be necessary. We appreciated Sam's knowledge and professionalism. If it ever becomes necessary, we will call Appliance Works and Sam again.
