Hobart A-200 mixer (OLD!) runs hot & shuts down.

That's a bargain if it works. Apparently the date is hidden in the last three digits of the serial number, so February 1998 seems likely. The only sure way is to contact Hobart themselves. They have a great service department. I have used many Hobart mixers in my catering career.

I found this;

As the previous poster mentions, you can't decipher Hobart serial or ML numbers. I have about 30 pieces of Hobart equipment ranging from mixers to slicers to reach-ins to dishwashers and I couldn't make heads or tails of the numbers. Finally, I got hold of someone at Hobart who I emailed all the model numbers, serial numbers and ML numbers to and they emailed me back the month and year of manufacture. Even after I got the information, I still couldn't figure out where in the serial and ML numbers the manufacture dates were buried.

The Hobart A-200 is an 80's product. These first came on the market around 1985. There is no way to date the one you have without examining it.

The best estimate is 25-30 years old.

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.

The oil leeking into your bowl is old grease that has broken down into oil and is getting past your oil seal you need to take out all of your old grease and oil replace it with hi-temp grease or a good grade lithium grease and replace your agitor shaft oil seal

on a a200 there is no oil. this mixer requiers grease. if mixer is leaking oil it is because the grease is broken down .you have to pull tpo cover off mixer remove trans. parts clean out old grease clean all trans. parts reassemble put top cover back on .then make sure mixer runs in all 3-speeds before putting 1.5 cans of -47grease back in grease can be bought @any hobart office

Check your recipe against the capacity chart found here: http://www.primasupply.com/images/hobarta200.pdf

You may be overloading the unit. Hope this helps.

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?

What you replaced were the contacts on the overload,correct?These 'heaters' look like springs?If so you have other issues.I'm a hobart tech and repair these mixers often.Are you mixing pizza dough?

Your overloading the mixer with too much product or not enough water,cut the batch down,the motor protection board is doing its job by shutting off.

No, do not swap hot and N.

First, verify rotation. As the attachment shaft rotates, it should push the engagement pin into the keeper slot. Looking down on top of the mixer, the planetary should rotate clockwise.

If the unit runs backwards, does it start slow? Can you get it to run either way by giving it a push start before turning on the power? If so, your start switch is not working properly. (Which is my guess) Check your capacitor.

There is mechanical and electronic start switches. (Metal arms and a contact or a little gold rectangular metal can.)
