Kitchenaid Mixer Repair?

Kitchenaid Mixer Repair? (post #56268)

My GF has a big Kitchenaid brand mixer that has problems. I don't have the model number, but it looks like this one:

The problem is that as soon as you slide the speed control to the number "1", the motor comes on at full speed. There is no slow speed for mixing in flour any more.

I thought maybe I'd get her another one like it. But mixers like this seem to go for $200 and up on ebay and they're about $300 new. Spending that much just isn't an option right now.

So I was wondering - Can you fix these things? The Kitchenaid website has nothing about repair parts that I could find.

I know I could fix it if I could get repair parts and knew what to replace.

I was hoping one or more of you had been through this and could point me in the right direction.

Mine doesn't now and has never had a "slow speed" for mixing in flour. I mean, "1" is pretty slow, but there's no "soft start" option and I make do just fine.

I would call Kitchen Aid.  They have been very good about replacing things which are under warranty, and although I'm sure this one isn't, maybe someone there could help you out with what to check and what to repair.


Edited to add that you need to get the model number before you call them.  It should be on the mixer.  Mine has a slow start, but it's probably newer.

In the past I have had mine fixed at an appliance repair center in my town. Look in the yellow pages. I even had the motor rewound on my original mixer.

Thanks for the help.

I had found the manual - Just hadn't had time to read it yet. I may print it out and read it over the weekend.

Hopefully the manual will help troubleshot the problem so I know what part to order.

I've had my KA mixer repaired at a local appliance repair shop. The ads in the yellow pages had listings for authorized service dealers.

Unfortunately our phone book AND yellow pages for the entire county is about 1/4" thick.

One of the drawbacks of living in a rural area - No appliance repair shops.

No two persons ever read the same book.

Yeah, know the problem well. We have some decent sized cities within driving distance, which helps with most things. DH, when he's home, works in one of them, so he frequently gets sent on lunch time errands. ;-)

I also forgot to mention that my GF lives 300 miles away. That also complicates things.

I need to find the parts, then take them up there to install them next time I visit.

Friends may come and friends may go but enemies accumulate.

If it used to have a slow start and no longer does, and if otherwise the motor runs properly, then I think the problem can be narrowed down to the controller board. IIRC, the typical AC motor controller is a Triac-based circuit and they just delay the turn-on of the triac to give partial current to the motor. Progressive reduction in the delay time gives the soft start feature.

The people who gave us golf and called it a game are the same people who gave us bag pipes and called it music and haggis and called it food.

"If it used to have a slow start and no longer does...then I think the problem can be narrowed down to the controller board."

It's not that it doesn't have a "soft start" - It's more like it goes right from "off" to "high".

There are no slow speeds any more. The motor runs at the same speed whether the lever is set to #1 or #10.

Still sounds like controller board to me. The lever really is not a mechanical gear shift. It acts more like a volume control on a radio. Sounds like the circuitry that translates the lever position to motor speed is NFG. Pop the lid off and I think you'll see that there is no direct mechanical connection between the lever and the gears. Since you haven't given us a model number, I don't know how the board is connected in, but I guess it is probably just slip on connectors and not soldering.

I've been told many times that I'm full of it. I am assuming that they meant arcane knowledge.

Basically correct, but it seems that there might have been 3 different systems over the year.

I an gathering that these 2 go together older models.

http://www.goodmans.net/get_item_ka-4162402_kitchenaid-mixer-speed-control-plate-4162402.htm

It has a centrifugal device and some contacts on a movable plate.

That might have had a single speed or arm might have moved springs to control when at what speed the contacts opened and closed.

I think that this is the next generation.

http://www.goodmans.net/get_item_ka-9701268_kitchenaid-mixer-speed-control-board-9706595-97012.htm

Probably a basic triac (similar to a light dimmer) control.

http://www.goodmans.net/get_item_ka-9701268_kitchenaid-mixer-speed-control-board-9706595-97012.htm

And this is the current version.

http://www.goodmans.net/get_item_ka-9703312_kitchenaid-mixer-sensor-9703312.htm
http://www.goodmans.net/get_item_ka-9706650_kitchenaid-9706650-9707220-speed-control.htm

It uses a sensor and separate speed control. My guess is that it is a true constant speed control and might include features use as slow ramp between speeds and shut down if overloaded.

The 2nd one does not include the pot where the control handle would connect so that might be separate device.

The latter one might include that, but can't tell from the picture.

I was slightly wrong.

Looking at the parts list for the 5 and 45 shown here

http://www.goodmans.net/get_dept_933.htm

They use the governor , control plate and phase board (called speed control board).

The diagram does not show how they interconnect, either electrically or mechanically.

The 26 & 25 use the near control with sensor. They don't show it, but my guess is that the control arm connects directly to the control board.

The service manual describes more in detail how it works.

There 3 different signals out the control board to command the phase board to produce 40 volts, 80 volts, or full power.

The spring on the control level balances theforce control board with the force from the governor.

And the trouble shooting section says that this problem is caused by a shorted phase board or a detached spring.

Hey Ron, so you and Bill did not get banned from all Tauntons?


Anyway, if you take the mixer apart, you will likely see what the problem is. 


DW has similar mixer but is one of the things I've never had to repair - still works great after 30 some years.


You may hit it lucky and only have to unstick and file the governor contacts (may be welded together) at least on the older versions. Have fixed a few of the old sunbeams that way - buy the sunbeams at garage sales for a dollar or so, great for mixing paint.

I probably won't be able to get my hands on the mixer for another 3 weeks, so I won't be working on it any time soon.

I did get the service manual downloaded and printed out, so that should help.

I have no idea why Bill and I (and others) were only banned from BT. Your guess is as good as mine.

The mixer you pictured is a K5SS and one thing that can cause high speed running on this mixer is a disconnected or broken control link spring that keeps the control plate snug against the governor. It is by far the most common problem, but speed control issues can also be caused by a faulty phase control board. The manual you downloaded can help you through the procedure.

The old K5SS looks a lot like the newer mixers based on the Professional 600 platform and the causes of high speed running are quite different because the Pro 600 uses an electronic speed control. Besides the name on the trim band, the newer mixers can be quickly ID’d by the fact that they do not have black brush cover screws on the side the of mixer case. With this class of mixer, speed difficulty can often be repaired by cleaning the contacts where the Hall Effects Sensor is connected to the speed control by a ribbon connector or by replacing the $15.00 sensor if the cleaning does not work. If neither of these fixes work, the $60 speed control module will be necessary.
