Our Kitchen Aid Accolade 400 has developed the equivalent of a stuck accelerator. When set on 'stir' or any of the low-speed settings, the RPMs increase rapidly, then the motor shuts off.

The solution for both of these is a large screw that sits at the base of the head where the head and the base meet - you'll see it when you tilt the head up. This screw should not be all the way in. You can adjust how low the head goes- in the case of your blades hitting the bowl you'll want to let the screw out a bit; in the case of the locking, you'll want to screw it in a bit more.

Why not just buy a power converter for the mixer and other electronics on Amazon. They are cheap and can be adjusted for
110 - 240 and can be used anywhere in the world.

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 JENNY, Merry Christmas and Happy New Year! Do not despair; there is a way to fix your KA mixer. From the symptoms you’re describing is sounds like your mixer’s (speed) Control Assembly and/or the Hall Effect Sensor has gone bad and either one or both parts need to be replaced.
As your mixer is out of warranty, the inspection and troubleshooting of the control assembly is something you can do yourself, particularly if your mixer is out of warranty. Just be sure to have the correct Part List manual around when you start to disassemble your mixer.
If you're lacking one, you can download it from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home
Click on Customer Care>Locate Manuals & Guides, and enter the 6 character model number, in this case, KN15E1X, and then select the first file, KN15E1XBW0.pdf (335.24 KB) that appears under Parts List (17). (check to see if this matches your mixer model).
Turn to pages 4 & 5 titled, "Case, Gearing and Planetary Assembly", which provides an exploded view for the assembly and disassembly of the mixer and locate Illus. Nos.8 & 9, Control Assembly and Hall Effect Sensor, respectively. I suspect one or both of these parts that are the cause of your mixer’s speed woes. Since the (speed) Control Assembly is the more complicated of the two, that’s where I’d focus my attention. The Hall Effect sensor is a very simple device and rarely goes bad.
First check to see if any of the connections have come loose from your Control Assembly. If everything looks tight then you need to replace it. Unfortunately the whole controller assembly is on a little PC board filled with resistors and capacitors, which was not meant to be 'home fixed' and my 'expertise' ends there. A local small appliance repair shop should be able to determine if the controller assembly is functioning properly or not. Or you can just order replacement parts without the testing.
As far as parts go, here are four potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com. Prices for the same part can vary widely between vendors, so do your comparison shopping.
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.

SOURCE: Kitchen aid mixer drops metal shavings in the

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.
