SOURCE: No power after replacing worm gear in Kitchenaid KSM90 Mixer

Remove the rear cap from the unit. Power comes in from the black wire with the white being common. Hold a voltmeter lead on the white and check for power on the black. Power goes across the bottom of the speed control unit via a buss bar. Check for power on the right side, I think it is a red wire (may be a white one). Power is taken into the motor via that wire, goes thru the windings and the brushes and then out the other brush wire and back to the board. Check for power on the return wire. If it is dead then either the windings in the motor are burned out or one of the brushes is dirty and needs to be cleaned and reseated prpperly [note there is one and only one way the brush goes in!!!! Install it incorrectly and the brush will not touch the commutator.

Try that and see if it runs after cleaning the brushes.

How to replace power cord on kitchenaid k4-b?

Take the four screws off that separate the top of the mixer from the stand,they are just above the handle that locks the bowls up when mixing.once you get the top off you will see where the wires connect to,simply disconnect the wires,remember which colors go where,because when you put the new cord on you will need to know where each color goes,it pretty straight forward,once cord is screwed in,put top of mixer back together and the screws are evenly tight.plug it in and mix away,if there's no power orbit sparks unplug right away and check wires ,to make sure you got in right spot and they are tighten down all the way.

Kitchenaid mixer K4-B cord replacement

Well you did well for never taking a mixer apart before, the only thing i would say is that you made a serious mistake with the lithium grease. KA uses a food safe grease that will not get anybody sick when it drips into the food being mixed. As to replacing the cord on current mixers (since 1978) all is done right at the rear opening now.

I have a old model K4-B. It runs well but makes a

Hi SCS7896, Merry Christmas & Happy New Year! Yes, the ‘large black screw looking things’ on the sides of your mixer head are the Brush Holder Caps, and they provide access to the electric motor’s carbon brushes, but they are not for adjusting. If you (or your husband) are DITY type person, and feel adventurous, and your mixer is not under warranty you can troubleshoot it yourself.
Since your mixer is a vintage KA mixer manufactured by Hobart, I doubt you will have your original Parts Manual on hand, but you might want to download the model K45SSW Parts List manual. The two mixers should be similar. You can download it from the KA website
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in this case use K45SSW, select the file K45SSWH0.pdf (341.41 KB) listed under Parts List (1) and then check to see how closely this matches your K4-B model.
Turn to pages 6 & 7, titled “Motor And Control Parts” for the disassembly and reassembly of the electrical components of your mixer, along with all the parts. Locate Illus. No. 32, Bush Holder Assembly, which includes Illus. Nos. 18, 19, 21, 22, 23, & 31.
Your husband would need to remove Illus. No. 23, Brush Holder Cap, in order to remove the brushes for inspection and/or replacement. If the brushes are chipped or excessively worn down they should be replaced. (NB: When replacing brushes make sure the new brushes are correctly oriented to contact the armature. The concave contact face should rest completely on the armature’s commutators. If you've turned a brush 90 degrees too much, it wont' seat properly and you'll get no 'juice' to the electric motor, so it won't start.)
I am more concerned that the growling sound you’re hearing is not a brush issue but it is more indicative of a transmission gear issue. You don’t say how old your mixer is or how hard it’s been used or if any preventive maintenance has ever been done on it? It may be time for some TLC maintenance, to include checking the quality of the gear grease inside the mixer head and inspecting the gears, particularly Illus No. 38, Worm Gear Bracket and Gear.
Turn to pages 4 & 5, titled “Case, Gearing And Planetary Unit” for the disassembly and reassembly of your mixer, along with all the parts. For starters, you should consider reordering the gasket (Illus. No 19) and O-ring (Illus. No 34). Once apart you can check for any other unseemly wear and tear on the gears, etc.
If you really feel the need to re-grease your transmission, you should use a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call).
If you need to re-grease your transmission, you should use a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call).
Here are five potential vendors in no particular order:;;;; and You should be search for ‘food grade grease’. Prices can vary widely between vendors, so do your comparison shopping.
Finally, here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer.
Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble and reassemble your mixer, should you decide to go that route.
If you feel troubleshooting and repairing 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
