Hi, I have a Kitchen Aid Artisan KSM150PSTE mixer and it only runs at full speed instead of Stir, 1 > 10. Not sure what part I should try to replace?

I would recommend that you first check the Hall Effect sensor which determines the mixer’s speed.  I had this exact problem and I actually went out and bought another Hall sensor for about $13.  I replaced the original sensor and made sure that the connection between the sensor and control board was nice and snug. My mixer worked as good as new! But I was curious to know if my original sensor was defective, so I put it back in mixer and again made sure all of the connections were snug and tight. Guess what?  My original sensor also made my mixer work!  There was nothing wrong with the original Hall Effect sensor except that the connection between the control board and sensor was not tight--unfortunately I didn't check the connection before I decided to buy another sensor. My guess is that the connection between the control board and the sensor probably loosens or comes undone over time from use and vibrations. To fix your problem:
1.  Download the mixer parts and diagrams from the Kitchenaid website to see what the Hall Effect sensor looks like. BTW the part number is 9703312.
2.  You'll need a phillips head screwdriver to open up the mixer gear case cover.
3.  Make sure that the connection between the control board and sensor is absolutely tight and snug.
4.  Also, make sure that the orientation of the sensor is correct.  It's difficult to tell which way the sensor should be connected because the control board has three prongs and the sensor can attach facing up or down. After you've made the connection, run the mixer. If it still doesn't work, disconnect the sensor, reconnect it with the prongs facing the opposite direction and try it again.  I actually found the right sensor orientation through a little trial and error.  But by going through this trial and error, I also had my Eureka moment when I realized that the original sensor probably would also work if it were reconnected with correct orientation.  
5.  This whole process probably takes about 10-15 minutes to perform.
6.  Finally, use your common sense and make sure to unplug the mixer before checking, connecting or disconnecting anything.

Hi. Goto kitchenaid.com and download the parts catalog for your mixer model, these drawings will assist you in the disassembly and reassembly of your mixer.

You'll need to replace the speed control in your mixer. This is a common problem. Be prepared to wait at least a month for your parts to arrive. Unplug your mixer before you open it up.

If you're still under warranty call kitchenaid!

Some of the gears may have broken or slipped off. You'll need t open it up to see why the shaft from the motor will not spin or you will burn out the motor with the power on trying to make it go. It might be a DIY job if you can see an obvious problem like a slipped gear, otherwise take it to a repair specialist.

Hi REDLACQUER. Sorry to hear about the metal shavings. This is probably not to best way to take iron in your diet... My first thought would be to ask if your mixer is still under warranty. If you’ve had the machine less than one year, then I’d let KA replace your mixer with a new one. However, I suspect like many who seek assistance from FIXYA.com, your mixer is out of warranty, so what can you do?
Have you been able to find exactly where the metal shavings are originating? From the symptoms you describe, it appears that the planetary/agitator shaft assembly may be rubbing against its housing and generating the metal shavings at higher speeds. Have you noticed any increased noise levels/squeaking/screeching when the planetary rotates? It’s also possible that the planetary is out of alignment and not rotating true. Could the agitator shaft been jarred or hit hard during set up or moving in or out of you storage cabinet? Or the shavings could be symptomatic of other internal gear problems, but that would be the least likely scenario as the mixers internal gears are pretty much self-contained.
The good news is that this can be troubleshot and fixed quite easily (OK, maybe with a little effort) by yourself if you are a DITY type person, and feel adventurous. However, before you start to disassemble your mixer, be sure you have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case, KP2671, and select the last file, KP2671XWH3.pdf (325.07 KB) listed under Parts List (24) (check to verify that it matches your mixer model).
Turn to pages 4 & 5, titled “Case, Gearing and Planetary Unit”, which provides and exploded view for the disassembly and reassembly of your mixer, along with all the parts. I suspect your Planetary Assembly, Illus No. 15, is rubbing somewhere against its housing, Lower Gearcase, Illus. No. 24.
To gain access to these pieces you’ll need the following tools: a regular or Phillips screw driver, retaining clip pliers, and a small drift pin punch and a small hammer. You need to remove the Transmission Housing (Illus No. 7) and remove all the lubricating grease from the transmission housing and gears (when removing the grease be on the lookout for shavings in the grease which would indicate excessive gear wear). This will allow you to remove Illus No. 25, 21, 18 & 19, Retaining Clip, Bevel Gear, Retaining Pin and Worm Gear Follower, respectively.
Once you remove the Retaining Pin (Illus. No. 18) the Planetary Assembly can be tapped down through the Lower Gearcase Assembly (Illus. No 24). With the Planetary removed, you can inspect it and the inside of the Lower Gearcase to determine where the shavings originated. Be sure to look closely at the Planetary Gear in the lower gearcase as well as the Agitator Shaft Pinion Gear (Illus. No. 12). That will also identify what parts need to be replaced, which you can order online.
You’ll need to replace the grease you removed with new grease. You should use a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call). Do not try to reuse any original grease as it may have ‘debris’ in it.
Here are five potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com (for grease). You should search for ‘food grade grease’. Prices can vary widely between vendors, so do your comparison shopping.
It can be messy but quite gratifying to diagnose and repair your mixer yourself.
Finally, here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer. The mixers displayed in the links are different KA models, but the principles are the same.

By not working to mean that the planetary gear wont move? or does it just make a weird noise when it is on a low setting? If the gear is completely stripped the unit shouldn't run on any speed regardless if there is mixture in the bowl or not. Since I can't see the mixer I would say that there might be a slight tear in the gear which would only allow the mixer to get stuck on a slow speed where as on a high speed it is running fast enough to skip that particular tooth. I understand that the mixer is brand new but when it comes to mixers you can strip a gear right out of the box depending on the consistency of the batter you are mixing. If the machine is under a year old it is under warranty and you are allowed free service by an authorized repair center in your area.
