KitchenAid K5SS Heavy Duty Commercial Stand Mixer Logo
John Powell Posted on May 14, 2007

KitchenAid K5SS mixer speeds up beyond set speed.

Mixer can be set on slowest speed and will start running at that speed, but then speeds up and sometimes slows back down. I checked the brushes and they look good and are about .75" long, so I don't think that is the problem.

    worked, but not on the lowest speed. Extracted the brushes; they looked fine, reinserted them, now nothing. We were very careful to insert the brushes so they aren't binding.

I have the same mixer and I believe your problem is the governor that is on the back of the motor. You can figure it out by downloading the repair manual here:http://store.mendingshed.com/kitaidparts.html The manual has all the info you need; including a troubleshooting section. The governor is availible from the the same site here:http://store.mendingshed.com/kagovernor.html What tipped me off on my K5SS was looking at the governor as it ran and I could see it moving back and forth; not steady like it should. Good luck!

Funky speed

Could also be a broken wire to the control plate. It's not very often the plate itself. Just looking in there while operating the lever may reveal something. The shaft at the bottom that moves the plate closes a set of points to start the mixer, maybe the points are loose and not closing when they should. Just be careful operating it with the cover off and alive.

Mixer works fine with speeds up to 6, but changing to 8-10, speed stays the same.

Sometimes can be caused by running too fast on the lower speeds. Should be 13 to 15 revolutions in 15 seconds on speed 1 then a slight increase only on speed 2.

SPEED CONTROL ALWAYS ON HIGH

Speed control plate at the back is stuck in the high position or you need a new phase board. That's the small PCB under the back cover at the top.

Model K5SS -- The speed control lever will not stay in the slowest position - STIR - but will pop over to the next position - 2. Can I adjust anything to fix this problem?

Open up the Motor Housing and inspect the Switch Lever with Stud.
The Lower Gearcase has many depressions which allow the stud to
snap into it when the Speed Selection lever is moved. If the Stud
is worn out then there isn't much you can do but replacing it.
3184193 is the Switch Lever And Stud part number for your model.

I could not regulate the speed as usual. Hubby removed the phase control board and a new one was purchased #9706595. It arrived and was installed and now the mixer won't even turn on. HELP please.

The K5SS is very similar to the 5-QT Artisan KSM150.
You need to adjust the mixer speeds. Obtain a copy of the K5SS Repair Part List from Kitchenaid.com. Remove the screw holding the End Cover and locate the three screws from the Control Plate. All three (2 top left and right, and 1 bottom) must all be adjusted. 1. Loosen the lock nuts enough & Turn the 2 top screws clockwise until they cannot be turned
anymore. Leave the bottom screw alone for now.
2. Use a dab of white paint or paper whiteout to mark the positions of the Phillips screws.
3. Plug in your mixer and Set the speed selector to "Stir".
4. Turn each top screw One full turn couterclockwise (alternating between Left and Right)
Keep making one full turn at the time (for both left and right) until the motor starts running.
5. Put your hand near the Agitator shaft and allow it to brush your finger slightly. Use your
watch or clock and start counting the number of times the shaft touches your finger in
60 seconds. The correct count should be 60 RPM (Rounds Per Minute). If it is less
or more than 60, give each screw 1/4 turn counterclockwise or clockwise and start counting
again. Now tighten both lock nuts.
6. Set the speed selector to "6" and turn the bottom screw either clockwise or counterclockwise
to achieve a speed of 180 RPM.

For your reference, the planetary RPM's for the 5-qt. tilt-head Artisan Stand Mixer are as follows:
Stir speed - 60
Speed 2 - 95
Speed 4 - 135
Speed 6 - 180
Speed 8 - 225
Speed 10 - 280

Motor does not start until switch is in 4-5 position, also the arm does not turn.

It looks like you may have two different problems. First, you must adjust the mixer speeds.
Second, if the motor runs at different speeds but the Planetary Assembly does not rotate, then
you may have a stripped Worm Gear Follower.

The kitchenaid k5ss runs at high speed at every setting of the speed control. How is this adjusted?

This is a bad rheostat switch. You will need to visit a repair center to have this fixed or get the part you need.

My Kitchenaid mixer (k5ss lift bowl?) smells hot

I think you have a K45SS. It sounds like there is a problem with one of the gears, probably the worm gear. The worm gear is designed to be the first to fail if the mixer has struggled with a heavy dough or other difficult to mix substance. The best way to establish the cause will be to open the head up and check the gears for signs of damage.
