We love our stand mixers and we work them hard, but even with proper care, sometimes they need an adjustment.
With a KitchenAid mixer, it's all about the contact between the bowl and the attachment, be it the flat beater, balloon whisk or dough hook. The grease must be returned to the gears after the worm gear replacement is complete and before returning the motor housing to the mixer stand. The speed control plate works with the switch lever, governor and the phase control board to control motor speed. When you move the switch lever to a speed, the lever positions the speed control plate at the proper distance from the governor to attain the desired speed.
The phase control board applies the correct voltage to the drive motor to maintain mixer speed based on signals it receives from the governor. A damaged control plate won't help the governor and phase control board control the mixer speed. Replace the speed control plate if it-s damaged. One of the rear two motor housing screws will have a lock washer on it. This lock washer screw is a fail-safe in case the other screws shake loose. Take note of the screw when you disassemble, because it must be returned to a rear position in the mixer.
There are four more motor housing screws in the back of the mixer that must be removed with a flat head screwdriver.

If your stand mixer motor sparks when it runs, the motor brushes are probably worn. This DIY repair guide and video show how to replace a stand mixer motor brush in 4 quick steps. Reinsert the tower gear into the bottom of the assembly and turn the gear by hand until the roll pin hole lines up with the hole on the tower gear shaft. The reason you may have to adjust your mixer is that during the manufacturing process, KitchenAid stand mixers are set for the beaters to just clear the bowl when mixing.
However, this clearance may need to be adjusted so that the beaters are closer to the bowl during the mixing process, without coming into contact with the bottom or sides of the bowl. When the mixer is adjusted properly, the mixing action pulls all the batter in from the sides and bottom of the bowl, leaving minimal scraping required. Depending on the model, the speed control is either done electronically (the "professional" models) or through a centrifugal governor system .
If it's a mechanical speed control, like mine, check that moving the speed control lever causes the black plastic assembly on the tail-end of the motor to move back and forth. Pressing the planetary back on the mixer by hand will not completely align the roll pin hole on the planetary with the hole on the gear shaft.

Departments Accessories Appliance Parts Exercise. When testing your adjustment, you should use the flat beater to ensure it just clears the bowl. If you've over- or under-corrected, the bowl may not lock properly in place, or you may hear the beater hit the sides or bottom of the bowl. If this happens, you may have to counter the adjustment slightly to correct it. These instructions also work to properly seat a BeaterBlade mixer attachment on your KitchenAid mixer. KitchenAid makes several models of the stand mixer, and all might need to be adjusted in order to address the beater-to-bowl clearance.
This information is in the product manual, but if you don't have that handy, it's easy enough to make this minor adjustment. From this I learned that while worm drive gear failure is a common first protective part to fail, it is not the only thing that might go. Hopefully reading through the troubleshooting list there will lead you in a useful direction.
If you cannot usefully diagnose the problem, see if there's a small appliance repair shop in your area. I agree with you that a KA mixer should last longer than six years and hope you can find a repair solution. After removing enough grease, the worm gear will be visible in the gear tower assembly.
Inspect the gear for wear and damage to verify that it is the cause of the mixer malfunction. I'm only talking about the Pro 600 model KP26's. I have the Kitchen Aid professional 600 and my beater isn't reaching the bottom of the bowl in a new unit, I just lowered the bowl and there the screw to turn is exposed.
I turned it a hair a little at a time to the left until the dime in the bowl moved like very slight with each pass. If the adjustment does not work for you on a KA Pro 600 KP26M1X model something is wrong. I really am glad you posted this helpful instruction about this adjustment. I called about repair, but they sent me a new one and had me return it in the same packaging and then they picked it up by UPS at no charge to me. I was so surprised that it encouraged me by several KA products.
That's disappointing to me enough to just go to another brand. Bowl-lift models have an adjustment screw on the lower portion of the stand and you'll need to place the bowl's lift handle in the down position to see it, after unplugging the unit. The adjustment to lower the beater is clockwise , while the adjustment to raise it is counter-clockwise . The phase control board works with the governor and control plate to control motor speed.
Replace the phase control board if defective. When your stand mixer doesn't run, the problem could be a lack of electrical power, broken wires, a failed motor or control problems. There are resources around the web that will show you step by step how to repair your kitchen mixer by yourself. Hi, i've replaced my worm gear assembly, the mixer spins without anything in the bowl, but when I mix a cookie batter the motor still works , but the paddle stops spinning.
Insert a pin punch into the hole in the gear shaft. Turn the gear shaft with the pin punch while gently applying pressure on the top of the motor housing. Replace the tower gear and tower assembly roll pin. With the washers on, install the new worm gear into position in the gear tower assembly.
The tower gear pulls right out of the bottom end of the assembly after the roll pin is removed. Lift the motor housing straight up to pull it off the gear shaft and away from the mixer. With the housing screws removed, the rear cover off, and the strain relief disengaged, the motor is now free from the lower half of the mixer. Because KitchenAid mixers are made to last many years you should expect to replace the worm gear in this style of mixer sometime during its service life. KitchenAid stand mixers are designed to survive a number of normal breakdowns and parts replacements.
Some parts, like one of the gears that spins the mixer, are even designed to wear over time and/or fail under stress. KitchenAid stand mixers usually stop spinning because of a failed worm gear, and this article explains how to fix the problem at home. When your KitchenAid appliances do too opt for replacement parts designed specifically to match our products. KitchenAid stand mixers provide the precision performance you need to prepare any dish. Turn your mixer on halfway to the "stir" speed – level 5. What you want to see is the beater contacting the dime and moving it around the bowl about ¼ to ½ inch every time it contacts the dime.
If it doesn't touch the dime, then you know your bowl and beater are too far apart from one another. This is usually the adjustment that is needed. We find the first sign of a possible misalignment appears two different ways. After creaming butter and sugar with the flat beater and proceeding to make the rest of a batter, we find that some unmixed portions are left on the very bottom of the bowl. When beating just 2 or 3 egg whites with a balloon whisk, the attachment may be barely contacting the egg whites in the bottom of the bowl as well. Having the beater in the correct position is very important.
If the beater hits the bowl, the finish could get chipped, which will affect cleaning, and this added stress can also cause problems with the mixer motor. For every appliance you buy for your kitchen you should check for reviews of the product online. Unhappy and very happy customers who are passionately dissatisfied or satisfied will usually take the time to write a review. First, be sure to check if your kitchen mixer has a warranty. If your mixer breaks down during this warranty period, you may not have to get it repaired at all. The manufacturer may just send you a new one, or they will pay for shipping and have you send the item to them for repairs.
Consider the fact that the kitchen mixer's worm gear is the most part of a mixer that will need repair. A worm gear is a mixer part that is supposed to break down throughout the life of your mixer. If yours uses electronics to control the speed, you'll have to go through the proper troubleshooting required. I have no experience with those types, but if your speed control is just going full-speed at all times I'd check for a blown triac. Once the roll pin hole is aligned, reinsert the roll pin by hand and tap it in the rest of the way with a hammer.
When installed correctly, a small length of the roll pin should protrude out each side of the pin hole. After installing the new worm gear, the rest of the gear tower assembly must be reassembled as well. This completes the installation of the new worm gear into the KitchenAid mixer. Finishing the repair is just a matter of reassembly.
The old worm gear is finally ready to come out of the tower assembly, and it will simply pull out. A roll pin holds the gear tower gears to each other. You'll need to transfer grease to the gearbox portion of the motor housing in the next step. A roll pin holds the planetary to a shaft coming from the gearbox. Trying to pry the planetary from the mixer won't do any good with the roll pin still in place, so it must be removed.
In this mixer style, the worm gear is made of a hard nylon material that is less hard than the other metal gears in the gearbox. This difference in hardness ensures that the worm gear breaks before the metal gears tear each other to pieces. The mixer's gearbox is positioned just above the planetary in the front end of the motor housing. Several gears inside the gearbox work together to spin the planetary. Just to clarify, the KitchenAid mixer part that spins is called a planetary.
This is the part of the mixer on the underside of the motor housing where KitchenAid accessories attach. So ridiculous, that a $2 fuse would require the replacement of a $55+ motor, when there WAS NOTHING WRONG WITH THE MOTOR, as the fuse had blown, PROTECTING THE MOTOR.

Are you looking for information on using the Kitchen Aid KHMS2040WSS0 microwave/hood combo? Download or print a free copy of the user manual below. This user manual contains important warranty, safety, and product feature information. Are there bushings that are worn that you need to be replaced? Looking at the worm gear and the gear it mates to appears that the shaft or bushing may be suspect.
There is also a retaining pin that needs to be removed in order to pull the worm gear follower. Removing the main cover, remove the back screw, take off the product band, and remove the 4 cover screws. This past week, I took my mixer out to use, after a rather long hiatus, and discovered the beater hitting the side of the bowl. Now, I knew THAT wasn't right, so off to google I went and found out about the screw. It was really hard to turn to the left, for my adjustment, but, I managed it in the end. I did the dime test and it seems about right.
Unfortunately, it's done nothing to fix the beater hitting the bowl. When I looked closer, where the bowl is held, the arms seem off kilter; one arm seems to be off to the side. I did notice the mechanism on the inside, but I'd like to know if anyone has an idea of how to fix this, before I go tinkering. I have contacted KitchenAid, which only told me to do the dime test or take it to a repair facility. Unfortunately, I did not even attempt to use this mixer until after my 90 day warranty was up. That's my fault for not verifying it right away, but it was purchased as a wedding gift, so I didn't have a whole lot of that 90 days left by the time we received it anyway.
H Fezzick, thank you for your response regarding adjusting the bowl height on a pro 600, however I don't know which nut you are referring to. Could you please tell me where or how percisely do I find this nut? Doineed to remove the metal band and top cover or is the nut visible from outside?
