Question about KitchenAid Food Mixers
When doing a second batch of dough it will not run on speeds 1 or 2 but accelerates to high speed. It's no problem when making one batch of dough, or cake batter, or whipped cream though. What is the problem and how can I fix it? Kitchenaid Hobart K45SS Mixer
Usually when the mixer runs only on high speed it is caused by the control plate adjusted incorrectly or the control plate spring unhooked. Remove the trim & end cover on the mixer and check the control plate spring, if unhooked, attach to bottom of the control plate and squeeze the spring end, also check the speed control plate screws,there are 3 screws on this plate, one at the bottom two at the top, see if adjusting the top screws slows your mixer down.
Next check the wiring of the mixer, Insure everything is wired correctly, to get wiring diagram go to the last page of the service manual. Here is a link to the service manual: http://lib.store.yahoo.net/lib/mendingshed/kitchenaidservicemanual.pdf
If neither of those fixes the problem it is probably a bad phase control board, or a shorted phase control board. With the line cord disconnected, pull the t-bar contacts to open and insert a piece of paper between them so they cannot close. Reapply power-the mixer should just run or buzz trying to run, if it operates at full speed the phase control is defective and needs to be replaced.
Use the service manual to aid you in taking apart the mixer, trouble shooting the problem and putting the mixer back together, based on the mixer only running at high speed some of the time I would assume it is the speed control phase board.
If you have any questions let me know.

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.

Hi REEDKL, Merry Christmas and Happy New Year! Based on your mixer’s symptoms, my first thought is that your mixer’s internal controller assembly (the speed knob), has gone bad. 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. Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in this case, KP26M1, and then select the last file: KP2671XWH3.pdf (325.07 KB) that appear under Parts List (21). Check to see that it matches your mixer model.
Turn to page 4, Case, Gearing and Planetary Assembly and locate Illus. #8, Control Assembly. This is what you’re looking for when you get the top (Illus. #1) off the mixer head.
First check to see if any of the connections have come loose. If everything looks tight then you probably need to replace it. Unfortunately the whole controller assembly is on a little PC board filled with resistors, capacitors and diodes, which was not meant to be 'home fixed' and where my ‘electronic expertise' ends. 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.
Although you don’t need to get further inside your mixer to make this repair, here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer that you might want to keep in your ‘toolbox’, should you have to delve inside your mixer in the future. The mixers displayed in the links may be different than your KA model, but the principles are the same.
If you feel this repair 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

Testimonial: "This is great information! I never expected to find help like this. Will move on it. Thanks!"
The problem with your mixer is the speed control switch, this switch is located at the back of the unit. It is usually black and has all of the wires coming into it, the Item # 1394070 and cost $27.95 it can be located at RepairClinic.com he is a link
You will have to adjust after you install you will adjust the two screws at the top of the switch while the machine is running inorder to make sure that you are getting all the speeds. Be careful as there is a possibility of electrical shock if you touch the wronge thing.
Thank you for using FixYa.
