Hello my name isXXXXX will assist you tonight
It sounds as though the switches have come out of alignment or a switch has gone bad
This is typically not a high expensive repair, and with the unit only being a 06 only half of its life has been used, most appliances should last 12 to 15 years
Do you have a listing of available service locations in my area (17545) where I could take the unit?
Im sorry I do not have any contacts in the area. GE will come to your home and service it for you, all you need to do schedule it at www.geappliances.com
