The microwave heats fine in the cook mode, but when I try to use the popcorn or potato button error F3H is displayed. It seems the humidity sensor needs to be tested and perhaps replaced. I'm not sure how to access humidity sensor? I see it on a parts diagram, but none of the diagrams who how/where to access the sensor. Is it accessible from the inside or from the top?
