Samsung 1500w microwave trips arc fault

Hi all, I’ve got a couple units where the Samsung 1500w microwave is tripping the 15 amp arc fault breaker. I’m assuming the microwave is drawing too much power during the spike. Any fixes besides rewriting or replacing microwave?

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.
