Howdy folks. I have a Maytag (Whirlpool) under cabinet microwave, model MMV5219DE-1, manufacture date July 2014. The light (on the bottom, not on the inside) no longer comes on. I've checked the bulb and it's OK. Any thoughts? I've got a multimeter and tools to disassemble the thing if necessary but would like some idea of what to look for before going inside. Thanks,
jeff
