My mixer master (Accolade 400) will only run at top speed
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.
Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble and reassemble your mixer.
If you feel troubleshooting and repairing is beyond your capability, then I would seek out a local small appliance repair shop in your area. KA Customer Care can give you names of local KA authorized repair shops in your area, but you can also do an online search to supplement what KA may provide you. Call to explain your circumstances and find out their hourly rate and get an estimate of what they think it would cost to repair your mixer. Also, always obtain three or more estimates – do some comparison shopping. Good luck and have fun. I hope this helps. Howard, Burke, VA

The planetary assembly fell off
My wife has the same model and the planetary unit fell off shortly after we bought it. Since we had moved overseas to a remote pacific island, getting it fixed under warranty was out of the question.
Since the rotary unit is a pressue fit, I pressed it back into place and it worked fine for about 3 months before I had to repeat the process. After that it became a monthly ritual.
I finally decided to fix it for good. What I did was drill a 3/8" hole in the center of the nub in the middle of the inverted rotary cover plate. I then drilled a 5/16" pilot hole in the center of the grooved shaft that the rotary cover plate presses onto. I then tapped that hole with a 18 NC tap. I was careful to tap it just a little shy of the depth of the cap screw that I was going to insert into the threaded hole so that it would jam as I tightened it. I then greased all the gears with a white machine grease and pressed the roary cover plate back onto the shaft. I then put a washer on a 5/16"-18 x 1" socekt head cap screw and clamped the thing together. It hasn't come off in the last 2 years.
While I am moderately skilled in this sort of thing it wasn't a precision operation. Since I was living in a fairly remote location with no shop, I did the entire operation on the kitchen counter using a handheld electric drill. Probably the hardest part was determining how deep to tap the shaft. I did it by trial and error. You can adjust the depth by using a washer or two of varying thicknesses.
I'm really surprised how lame a design using a press fit for this assembly is. They could easily prevent the problem by using my approach or even putting a cotter pin through the shaft and reciever tube in the rotary cover plate (a small hole would be needed in the side of the tube to set the cotter pin).
From what I've seen on the internet while looking for a solution, this is a fairly pervasive problem.
We thought we were buying a high quality machine that we thought would be reliable in our remote situation. Fortuantely, other than the falling rotary cover issue, the machine has worked great.
