Which is the right partner of T1? IS THE T7? OR THE T4/ OTHER T2.IS THE T8 OR THE T5?

Having 9 wires means it is a 3 phase motor.
For 220 to 240 Volts - L1, T1 and T7 go together. L2, T2 and T8 go together. L3, T3 and T9 go together. T4, T5 and T6 go together.

For 440 to 480 Volts - L1 and T1 go together. L2 and T2 go together. L3 and T3 go together. T4 and T7 go together. T5 and T8 go together. T6 and T9 go together.

Some ...what you may consider silly stuff...
1 check the outlet that you are plugging your mixer into it may be bad. Not the wire but the plug in the wall may be bad, plug a hair dryer in on high if it runs for 60 seconds it ok.
2 check the plug of the mixer make sure it is not bent at the wall pins
3 open the rear of the mixer by removing the round cover at the rear of the mixer look for loose wires, sometimes the socket connectors on the speed switch break off.
4 there are three screws on the speed control switch that control the mixer, sometimes after time these screws can actually turn due to vibration and the mixer will just not start....so.....start with the top right screw and turn it counter clock wise a quarter turn and start the mixer if it starts even for a half a second then the problem is in the switch. and your only problem is the proper timing set by the three screws.
5 gears inside the mixer can strip and freeze the motor so nothing turns...put your ear next to the machine mid way and turn it on ...if you hear a hum from inside then it is a gear problem.
6 If your machine is older then 1978 then it may be the IR filter inside the mixer (hard to find )
7 the carbon brushes that are located on the side of the mixer may have finally worn down (cheap fix) but there are four ways to put the new brushes into the machine and only one way works. You have to be careful with the beveled edge of the new brush and which way it fits back into the housing.
8 Now you are inside the mixer if everything else fails, the motor is the next step and it will require a full tear down, to repair, there are two parts the armature and the winding and each will take about thirty-five bucks to get and either or both will take about 2 hours to repair but if you go all the way down then you need a new gasket and gear grease clean and re-pack too. At this point you are performing an overhaul . let us know if this helps.

Hi Patricia,

Fare. Well. My Lady.

There could be several problems some painful some not so much, the simplest one is bad wall plug or bad plug wire, the hardest is that the motor burned out, but i don't think so. The most likely solution is the speed control switch. There are three scres on the switch in an inverted triangle shape/form. The one on the bottom has probable been turned just enough to stop your mixer from working. The speed control switch that you use pushes against the screw every time you turn your mixer on eventually it can turn by pressure and it will shut your mixer off with just a 1/16th inch turn. It is a very simple fix.
Where is the speed control switch? Glad you asked. It is in the rear of the machine. There is a round bubble shaped cover at the rear of the mixer called the end cover, it has one screw (Phillips head) on the top. Take that screw out, then grasp the cover and lift up and away from the mixer. Be careful there are two fragile hooks on the cover that can break if you twist it left or right, just lift up and pull away. when you have removed the cover you will see a black and copper plate staring back at you (it might be all dusty with flower and food particles) look for the adjusting screws at the top left and right corners and one at the bottom center of the plate. The one at the bottom center is the culprit. Take a Phillips head screwdriver and turn it left an eighth of a turn and turn the machine on, if it doesn't work leave the machine on and turn the screw in the opposite direction . ill bet a steak that the mixer starts. if it does you need to replace the speed control plate or take the screw out and put some lock tight on it. BUT!!!! when you do this you will have to completely re-tune the speed of the machine. So if it starts just leave it and you may have to do this once or twice again in the next ten or twelve years. Let us know if this fixed the problem. there are several other possible causes that could make the mixer stop but they are more painful.

I fixed mine (my wife's). Kitchenaid 3-Speed Hand Mixer KHM3WH. Here's how I did it.
This is a pretty old mixer. My wife bought it at a thrift store for $1. She brought it home, we found the beaters and whisk beaters on eBay. Paid $34.00 for both sets of beaters, but when we received them we found they would not stay in the mixer. Oh we also bought the alternative/replacement beaters from Sears, parts online. I don't think those will work with my fix. However with some $0.92 rubber washers from Lowe's and a heavy duty paperclip I fixed the mixer, and it works flawlessly. Maybe some stainless steel wire would be a better, more permanent fix.

You cannot wire a three phase motor for single phase and you cannot wire a single phase motor for three phase. If you have a three phase dual voltage motor your options are 220 or 440 volts. If you have a single phase dual voltage motor your options are 120 or 240 volts. A 208 volt Hobart motor will only function correctly on 208 volts and is not dual voltage.

It sounds like you get a degrading or bad start capacitor (locate right behind motor cover (see fig 22, page 12 of part catalog, cost $13). Here how you can check if your machine still work properly: 1- Rotate the agitator shaft manually to check for any binding. 2- remove two wires from the capacitor. 3- Use a small jumper, connect one end jumper to one wire and touch the other end jumper to second wire 4- As soon as motor start, remove the jumper. Good luck, If your ,machine have never have preventive mainternance it is a time to do so. (atva)

The ground wire attaches to the ground lug under the top.

Sounds to me like the start switch contacts are welded shut.If you have a multimeter set it to ohms,remove 1 wire from the switch,put your meter leads across the switch and if you get a reading that switch is bad.If you dont get a reading i would check the side switch on the contactor.Im a hobartt tech and repair these mixers alot.Let me know.

I had the same problem. Had to strip the machine down to get to the motor. On the top is a moving plate with various capacitors etc mounted. On the front side there was a Capacitor (At least I think it was) with the wire broken.
I resoldered it and the machine now works fine.

I hope this helps
