GE Spacemaker Microwave (JVM1630BH003) hood light...

Question

I have a GE Spacemaker Microwave (Model # JVWM1630BH003) that recently blew a bulb in the range hood light. Since that bulb blew, I have been unable to toggle the lights off (they are locked in the "on" position). I have tried replacing the bulbs and unplugging the unit and pluggin it back in - no luck. Toggling the light switch does evoke an audible "beep" each time (normal) and the display toggles between "Light On" and Light Off" (normal). I am thinking a relay is cooked (no pun intended). Any thoughts? Obviously I'd prefer to fix it myself.
