Dwayne H Fort Worth , TX October 06, 2014 Appliance: KitchenAid 30" Built-In Microwave KBMC140HSS02 Kitchenaid Microwave Kbmc140hss02: Inside light bulb burnt out. How to replace Microwave Door Torsion Spring (Right Hand). Removed the Microwave from the wall, then had to almost completely disassemble the sheet metal surrounding the microwave unit itself. Lots of screws and wires to work around. Takes 2 people to remove the microwave and set it on a stand outside of the wall unit. Once you get to the light bulb, the replacement is easy, just very challenging to get to the light bulb. 46 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
