KitchenAid KSM90 Ultra Power Series Stand Mixer - Page 9 - Answered Questions & Fixed issues


VLCMM: You don’t say if you have a ‘tilt-head’or a ‘bowl-lift' mixer, but you can easily download a PDF version of yourOwners Manual from the KA website (http://www.kitchenaid.com/flash.cmd?/#/page/home). Click on Customer Care>Locate Manuals& Guides> and enter the 6 character model number (in your case, use KSM90P)and select the last file listed that appear under Owners Manuals: KSM90PSWW0.pdf (2930.74 KB)and save that file to your PC. You’llneed to have Adobe Reader to be able to open it. Turn to Page 11 and you will find theinstructions for adjusting the mixer head height. I have extracted the instructions below:
Beater to Bowl Clearance
Your mixer is adjusted at the factory so that the flat beaterjust clears the bottom of the bowl. If for any reason, the flat beater hits thebottom of the bowl or is too far away from the bowl, clearance

Tilt-Head models
• Unplug mixer.
• Lift motor head.

• Turn screw (A) SLIGHTLY counter clockwise (left) to raise flat beater or clockwise (right) to lower flat beater.
• Make adjustment with flat beater, so it just clears surface ofbowl.
If you over adjust the screw, the bowl lock lever may not lockinto place.


Bowl-Lift models
• Unplug mixer.
• Place bowl lift handle in down position.

• Turn screw (B) SLIGHTLY counter clockwise (left) to raise flatbeater and clockwise (right) to lower flat beater.
•Make adjustments with flat beater, so it just clears surface ofbowl.

It's the grease that was put there during the manufacturing process. The seal has worn out, it must be replaced.Don't forget to put back the lost grease.

First disconnect the power, and remove the carbon brushes again. They will only go in one way and if incorrectly placed inside the unit, the mixer will not operate even if you fix the problem. If the brushes are correctly placed inside the mixer then this problem will most likely be caused by the main control board. You can check this visually by removing the back panel with the power removed. Once you remove this you can see the main board, visually inspect it for any burn marks and also smelling for ant burned wires can prove useful. Part number for the main control is W10119326. Hope this helps.

Thanks

CCFSILVER - When you say your speed selector is fussy, do you mean fussy in a 'electrical' sense or fussy in a 'mechanical' sense? Also, you didn't say if the short is causing power to the motor to be cut or what specifically the short is doing. For now I'll assume that you mean 'fussy' in an electrical manner. That being said, the speed selector is fixable. If your mixer is under warranty, contact KA and ask them to remedy the problem. If it is not under warranty, then you can attempt to fix it yourself. This will not be for the weak of heart, as you have to disassemble your mixer. It that is not within your capabilty than you should take the mixer to an authorized KA repair shop in your area. If you think you can do it your self, great!
First, do you still have the KSM90 Parts List? If not, you can download a PDF version from the KA website. Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number (in your case, use KSM90P) and select one of the files that appear under Parts List. If you turn to page 6 you will find the exploded view of the motor and the speed control. I suspect your fussy selector issues are being caused by Illus Nos. 24, 25, or 27 (the Governor Assembly, the Control Plate Assembly or Phase Control Board, repsectively). I would order all three parts on the assumption that if one has gone bad, the others aren't far behind. 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 may vary widely between vendors, so do your comparison shopping.
Good Luck, I hope this is helpful. Howard, Burke, VA

sm_schedule, the side bolts you removed were, in fact, the brush holder caps, and if you remove the brushes, you cut off the power to the electric motor (armature). I suspect that one or both of the brushes is (are) not seated properly. Did you remove the brushes to replace them or were you just inspecting them? I'd suggest removing them again and make sure the concave contact face of the brushes are resting completely on the armature. If you've turned a brush 90 degrees too much, it wont' seat properly. As far as adjusting the mixer head so that it doesn?t droop, this should be pretty easy to fix if you?ve got a small blade screw driver and a small hex driver (or jewelers screw driver). First, do you still have the KSM90 Parts List? If not, you can download a PDF version from the KA website. Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number (in your case, use KSM90P) and select one of the files that appear under Parts List. Turn to page 4 - Case, Gearing and Planetary unit, which shows the exploded view diagram and locate Illus. Nos. 29 & 30. Page 5 lists the parts as Adjusting Screw and Set Screw respectively. What?s probably happened is that over 12 years of operation, the vibrations from your mixer has caused the set screw to loosen and drop, hence the lower mixer head. Both screws will need to be ?adjusted? to move the head back to its original position. Now the problem is removing the head from its pedestal. Turn to page 8 and gently remove Illus. No. 7, Hinge Pin, with a hammer and pin driver. With the hinge pin removed the mixer head and pedestal can be separated and you should have access to adjusting and set screws. I would inspect them for wear and tear, and replace them, if you deem appropriate. It may take a few trial reassemblies to get the mixer head back to the original factory position, but once there, everything should be OK. I hope this helps! Howard, Burke, VA

This is common problem among kitchenaid mixers. If you are hearing no motor sound what so ever, The likely cause is the carbon brushes are worn or gone completely, and will need to replaced, they are located at the left and right sides of the unit and only fit ONE way. part number for both brushes is W10260958 and comes one in a package. These are a wearable part and when gone will not create an electrical field for the motor to run. If however these are visually OK, the next probable cause of this will be the motor control board, this can cause a great deal of electrical burning smell when it goes. part number for the board is W10119326. The board can be replaced but does require some know how of the unit.Hope this helps

Thanks

Tegan, sorry to hear you tilt mixer head is drooping and causing rubbing problems with the mixing bowl. This should be pretty easy to fix, if you?ve got a small blade screw driver and a small hex driver (or jewelers screw driver). First, do you still have the K45SS Parts List?

ambpsg143, Sorry to hear you don't have power. I'm assuming the outlet you're using works and you've already checked your breaker box to make sure the circuit breaker hasn't tripped (or blown a fuse if you still have a fuse box). If all that checks out OK, then it is definitely a power issue inside the mixer, which means it a couple of things could be conspiring against you. My first thought is that It may be a bad controller assembly (the speed knob), or it could be the motor, but either way it's something you can check yourself. I'd start with the controller assembly and inspect that first. It's possible a connection has come loose. 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'. My 'expertise' ends at being able to recognize a resistor from a capacitor, but I don't get much deeper than that. A local small appliance repair shop should be able to determine if the controller assembly is functioning properly or not. The next possibility would be with the motor itself, but electric motors are pretty simple mechanisms and generally don't fail, so my bet's with the controller assembly. I hope this helps.

kazikeva... It's not very clear what stopped working; the motor, the mixer, what, in particular? You don't tell me how old your mixer is and how much it's been used, all relevant towards pointing me to the problem(s). The more detail you can provide, the better my answer will be towards helping solve your problem. Are you getting any sound when you hit the start knob, or is it just dead silence? If you have dead silence, then it is definitely a power issue, which means it a couple of things could be conspiring to make your mixer not run. It may be a bad controller assembly (the speed knob), or it could be the motor, but either way it's something you can check yourself. I'd start with the controller assembly and inspect that first.

A local small appliance repair shop should be able to determine if the controller assembly is functioning properly or not. The next possibility would be with the motor itself, but electric motors are pretty simple mechanisms and generally don't fail. If you?re getting 'noise' from the motor but the mixer won't turn, then you've had a mechanical failure in the transmission box or planetary gear assembly of your mixer. The inspection and troubleshooting of the transmission is a DITY capability, 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. You want Part No. 8212257 for your mixer, which you can download from KA customer service. I hope this helps! Howard, Burke, VA

thebsjunk - I don't know if you've canned the old mixer. If you've bought a new KA, congratulations to Kitchenaid. If you haven't, there's still a possiblilty that you might be able to fix it yourself. (For the price of KA mixers you'd think they's last a 'lifetime', but alas, KA quality is sorely lacking from their current products...but I editorialize.)
It's quite possilbe that you've had a gear tooth break in the transmission, which would lock up and prevent the planetary gear (agitator) from rotating in mixing bowl. This is what happend to my wife's 6 Quart Pro KA mixer. Since it was out of warranty, I decided to troubleshoot myself. First I downloaded the Parts List manual from the KA website so I knew what to expect. Then I easily disassemble the mixer to find that a bevel gear tooth had broken. After ordering the correct parts, and reassembling, it works better than when we first upacked it. The loud whining is absent...
If the motors gone bad, you can still replace that, too. Fixing your mixer yourself is much easier than shipping it off to a repair center, and you have the gratification of doing it yourself.
I hope this helps! Howard, Burke, VA

Well, from the postings on here I don't think kitchen aid is a top quality piece of work. Me? Sun beam mixmaster. One of the very few that has the power, durability and lifespan of a professional tool. Go the difference and.Know the difference.

That is food grade grease separating. Pick some up at an appliance parts store. You may have to split themotor housing to add it if it has no point of greasing.

Hello. Actually, the wisk releases just like the other attachments do......... just lift and twist it 1/4 turn.

KitchenAid KSM90... | Answered on Oct 13, 2009 | 67 views


it is hard to tell you exactly what it could be, but a common problem is after a while the transmission gasket does deteriorate and will begin to leak oil.the gasket is part number4162324. the rattling noise inside your unit is most likely cause by a chipped gear inside, this can happen when the unit is put under heavy loads, such as dough. this problem could get worse as there may be fragments inside that will damage it more.hope this helps

The silver trim piece on you mixer can be reattached by taking the back off your unit. once this is done you will be able to see two screw holes on the left and right of your unit. simply wrap the band around the mixer correclty and use fine threaded phillips screws to attach the trim. hope this helps

With the machine unplugged, remove those two black screws on the side and pull out the motor brushes. Make sure the metal blocks on the ends of the springs are in good shape. These wear out and the screws are there to easily replace them. You can order new ones cheap from kitchenaid. If it's not those brushes then the problem could be in the gearbox and you can't fix it. Are you sure it's not a bent wire whip or mixing paddle banging against an improperly seated bowl?

splash a little water where it comes apart. Water will lube and soften anything holding the attachment. make sure it's unplugged so you don't lose a finger or twoOr pour a few drops of cooking oil on the button and let it run down the sides into the mechabism. good luck
