Planetary stuttering and stopping while mixing

I would start by taking a look at the bevel gear. Luckily ifixit has a guide to access it. Looks pretty simple to me. Just follow the steps carefully and keep track of the parts. If you see chipped teeth or metal chunks/shavings, ya might need to replace the gears and refill the grease. I’m not sure what kind of grease they use but I’m sure you can find out online.

Maureen,

Usually, we see the mixers will stop spinning under a load. Such as a heavy dough, this is a sign of stripped gears. You can easily open this mixer up and check the gears with very basic tools. There are 4 main gears inside the mixer, and because they are all metal there is a good chance you have stripped more than one gear.

I would start by taking each gear out and cleaning it with WD40 and paper towels (unless you have access to a parts washer) then inspect each gear. Most of the time it's very obvious which gear is stripped as it will be missing several teeth. But any gear showing wear should be replaced.

You should also clean out the entire gearbox and pack it with new grease as little bits of the old gears can be in the grease and cause problems in the future.
