One of my Mother's range hood lights quit working. Take out the hood filters, take out 6 screws which takes the front and cover for fan off. Checked with meter and found that one of the light sockets had gone bad.Located model number on side wall under range hood filter. East to order and easy to install. Unplugged old wiring harness, snapped in new sockets and plugged new wiring harness in. Fixed in five minutes and mom thinks I'm a genius !
