This is a very old mixer that when mixing bread dough for a while ,it shuts off until somethng electrical cools down and it works again until it shuts down again. I replaced the heater relays on the side of the motor starter, still shuts down when something electrical heats up.

I'd say you're most likely overloading the mixer. This mixer, and others similar in size, are frequently overloaded by people making pizza dough. If you are making dough, keep in mind the A-200's capacity is 9 lb. of 40% A.R. pizza dough, mixed for 5 minutes maximum. If you need to mix longer, the batch must be cut down even smaller, but I don't even know if you're mixing dough.
Try running the mixer unloaded (i.e. nothing in the bowl) for ten minutes or more and see if it gets hot. If it still gets hot, the motor's start circuit (varies depending upon age of the A-200; Hobart used numerous motors in the A-200 over the years, incorporating different starting circuits) most likely has problems. If it doesn't get hot when operating unloaded, then you're probably overheating the mixer by overloading it.
A thermal overload is an option on the D300 and is self resetting. Assuming your machine is being operated at it's full rated voltage, you might have to cut down on the amount of dough you are mixing. If I recall correctly, the relay and overload is located in the base or behind the speed selector plate.
The Professional 600 has a metal gear housing with a metal gearing. Because of this, the Professional 600 will generally run louder than other stand mixers that may have a nylon/metal mesh gearing.
How long is the bread dough being mixed for? Kitchenaid stand mixers must be used on speed 2 for bread doughs, using the spiral shaped dough hook, and mixing for no longer than 7 minutes.
If the flat beater is getting caught on the bottom of the bowl, pleasure assure the bowl is being seated correctly. You will place the bowl on the mixer arms on the left and right hand side. You will also want to take your fingers along the back of the bowl, where it butts up against the base of the mixer, and press downward. You will hear an audible click as the bowl falls into a spring latch and allows the bowl to sit flush and secure. If this is not being done, the flat beater may strike the bottom of the bowl.
If this was not the cause of the problem, please consult your Use and Care Guide about the beater to bowl adjustment. This is an easy adjustment made with a flat head screwdriver that can quickly correct the problem of a flat beater hitting the bottom of the bowl.
I'm a hobar tech and repair these often.The problem is the overload contacts are opening so the motor doesnt burn up.I know the mixer is old and the overload has weakend over time or simply the mixer is being overloaded with too much product.Did you just get this mixer?change the recipe?mixing pizza dough and adding ice?Any new employees if it's in a buisness?
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.
