K45 started smoking while mixing cookie dough

If the motor itself is slowing down, that is one thing. However, if you mean by "dog" that there is what sounds as if a gear is slipping then the solution is straight forward. The worm (follower) gear needs to be replaced.

There are videos on the net which show how to do this and the Service Manual can be found at:

Let it completely cool and then start again. It overheated because your speed was set too low for the heaviness of the dough. I have burned up three kitchenaid stand mixers so far making bread. go up one setting at least; if it is straining, go up another.

Hello Veelec,

As the machine is mixing dough it seems that it is getting sluggish. This is caused by the machine being over loaded. Although it is a 30 qt mixer that is for liquid filled capacity. I do not know what kind of dough you are mixing so I will give you a light to medium dough and then the heavy dough capacity. Also on this machine all dough should be mixed in speed 1 or low to keep from damaging the machine.

You will need to know the Absorption Rate (AR) of you dough, to find this you take the weight of the water divide the weight of the water and multiply by 100.

AR = Water Weight / Flour Weight x 100%

The higher the percent the higher the capacity the lower the percent the lower the capacity. Also the temperature of the water will have to be considered as the colder the water the harder the dough it is to mix the dough the batch should be reduced by 15% to 20% for water temperature between 65-75 degrees.

For a Light to Medium dough with a 60% AR the unit capacity is 45 pounds in first speed.
For a Heavy dough at 55% the units capacity is 30 pounds in first speed.

The above capacities are for bread doughs, if you are doing pizza dough, dough nut dough or wheat dough please post back to this thread and I will help you to find the capacities.

I hope that I have helped you with your problem and would like to thank you for using FixYa to find a solution to your problem.

Your mixer may still be good, let it cool down and then check it out, If it runs OK then there is no problem. The motor in your mixer probably over heated from trying to mix bread dough which will make any mixer work hard. These mixers will get warm when over worked but unless heavy smoke was coming out and you were getting a burning enamel smell it is probably OK. Let it cool and try it but I suggest you not use it for bread any more.

well Kevin your mixer is indeed old and the parts for it are most likely no longer available. I would first visually inspect and wiring in the unit. if this seems okay, it could be that your field winding is gone or the worm gear inside that drives the unit is simply burnt out. hope this helps.

Thanks

The mixer motor has probably overheated, as proper use and care was not being followed with the stand mixer.

Bread doughs are recommended to be mixed on speed 2 only and never for longer than 7 minutes. With the resistance of a bread dough that is provided against the beater, mixing for over 7 minutes may overheat mixer and cause smoking.

Please consult your use and care guide to refresh your memory about how to properly use your mixer for making bread doughs.

Hi. Congratulations for researching mixers. I wish I had before I bought my Kitchenaid HD Pro. All mixer manufacturers over-rate their products. Goto www.consumeraffairs.com and do a search for each mixer you are considering. Most mixer failures are caused by mixing heavy cookie or bread doughs. Although manufacturers claim that their mixers can easily handle these doughs...They cannot! My Kitchenaid self-destructed after 30 batches of bread dough. "For the way it's made"! Indeed! I solved my problem by buying a Hobart N50 mixer. It's a 5qt. and handles anything I throw into the bowl. I bought mine used, and refurbished it myself. New these units cost $2,035.00 USD.

If this solution has assisted you, please rate it. Good luck! ricardok45.

Hi. You should consider a few things. They type of hook you use, can greatly affect your end result. If you're making a yeasted dough with a high protein percentage 12-13%, you should be using an "ED" hook, this is a spiral hook that has a sharp turn at the tip. You can find them on eBay for a competitive price. I believe that Hobart also sells them, but for a higher price. They are very good for mixing pizza type doughs, they also do an excellent job kneading the dough.

Have you checked the flour for lumps before it goes into the mixer? Have you tried sifting the flour?
Are you adding all the liquid and flour at once? If so try adding flour in stages to all the liquid. If you find that this solution helps you, please rate it. Good luck! ricardok45

you fried the motor it is not worth repairing

Hi. Kitchenaid's warranty is 1 year.

Most likely, the plastic transmission housing has failed, causing damage to the working parts inside your mixer. Take it to a local repair place and have them work up a quote to repair it. It will take at least a month to get the parts.
