If your trailer is less than 1 year old, Call GE service and they will come out and replace the bulb free. If so, watch the serviceman as he replaces the bulb as ours bulb has blown twice know. Once under warrentry and last time I had to replace the bulb. Its not that hard to replace as bulb is located in top front of microwave. You have to take the wood trim off and the top screws on the top of the microwave. We purchase the bulb at Lowes. Hope this helps.
