The light under the microwave that luminates the the stove doesn't work. The switch activates the light but light doesnt come on. Have taken bottom off microwave to expose wiring for light tested wires to see if there is power and got no reading. How do I get access to switch on outside panel that I push to activate light? Is that my issue?

Dave for Model Number lmv1630bb

ANSWER Hello Dave, The switch to activate the lights for the bottom of unit is incorporated into the control board and cannot be replaced individually. If there is no power to the lights then the control board ACM49437018 would be what would need to be replaced.
