There is an upscale condo complex a couple of towns over that was built about 4 years ago. They all used a particular brand of exhaust fan/ microwave over the range and all were tripping the AFCI. Most of the problems with today's equipment is from not building equipment to established parameters. It could be component substitutions or making the equipment cheaper. I believe the resolution was to replace the power cord with one that had a filter of some sort. It was either that or remove the AFCI.
