GE JVM1651 Microwave

Question

I changed the hood bulb on this model, and I did not unplug the microwave. This caused me to trip a circuit breaker. Upon putting a new light bulb in, I noticed that the light doesn't work. The microwave works fine except for the hood lights and the vent fan now doesn't work. Any ideas? It seems there must be some common part that these two components share that got burnt out.
