Have a Hobart a200n mixer and it won't start even with the hairs closed. My sparky took the cover off and got it to rotate by bypassing the contactor, does it just need a new contactor? Thanks.

Check the coil in the contactor is getting power . If it is the coil is gone and if not a safety switch or switch is not working somewhere.

When I turn the machine on it makes a buzzing noise, (not loud but it might be like an alarm).

If the mixer is still running and making the buzzing noise one of the electrical contactors is making the noise and should be replaced.
If the mixer is not running and just making a buzzing noise it can be because off single phasing, check the incoming supply to the mixer and make shore you get the right voltage to the motor (test on motor connection terminals)if the voltage to the motor is right the motor might be faulty

Motor burned up?

What is the specific issue you are having with the mixer that makes you feel that the motor is burnt up? There is a variety of issues we see with KitchenAid mixers, however the motor being burnt up is actually rare. If you could get me the model of the mixer (that is under the base of the mixer on a label), then I can tell you what to look for in the mixer.

The most common issues in a KitchenAid mixer, depending on the model include: gears, brushes, and electrical components.
The grease is always black, it is actually a dark brown color but looks black, over time it can break down since it is vegetable based and can leak out of the mixer.

However I find that in 90% of the cases the repairs are fairly easy and worth the repair.

If you can get more information, or if you have questions, call our customer service team and they would be happy to help.

Hobart P660 keeps shutting off and tripping the breaker

Sounds like the cable is too small. If you're hooking it up to 15 amp breaker you need the correct diameter size extension cord, and the equipment cannot be rated more than 15 amp or you'll have a problem. I perceive this may be the solution based on the fact that you said that the motor was not coming up to speed.

When i push start button it runs let off button it stops

If you do not have a bowl guard then it is most likely the side switch on the contactor. If you have a bowl guard, it could be the bowl height switch or the contactor side switch. Make sure there are no loose wire connections before you replace parts. The bowl height switch may just need adjustment.

I have a: H-600T. Serial #11-369-290. Is this a 1,2, or 3 phase?

It's either 1 or 3 phase. Check the data plate. If it has a two pole contactor it is three phase, if it has a three pole contactor then it is three phase.

Problem for KitchenAid 300 Watts KSM90 Ultra Power Series Stand Mixer Motor will not operate

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
