Just picked up a new in (opened) box mixmaster. Bowls still wrapped up in a waxy type paper. Cord was supple, paint and decals perfect. Juicer attachment included. Mint owners manual

Problem is: the motor was seized. I was able to break it free, and got it to turn under its own power. It's certainly not going full speed and I didn't want to continue running in fear of burning something up. Does anyone have any tips or repair manual ? I imagine it just needs cleaned and lubed.

I bought it right as I was walking out the door so no pics yet. I'll post some tomorrow or Monday.

I have the service manual in Automatic Ephemera. I too found a model 11 new in box that was sized up. At some point I'm planning on taking it apart completely, cleaning out the old grease and putting in new grease.

That is the rare model 11

You have the rare model 11 Mixmaster. I say rare because it was only made for two years starting in January 1955. This model also has the distinction of being the first Mixmaster available in colors and chrome (although it has been discovered that they were a small number of chrome model 10’s made in 1954 as pilot models).

Wow!  I absolutely stunned that there are still 'new in box' appliances like this Sunbeam Mixmaster out there still!  Congratulations on this find - it's just gorgeous!!   Can you tell I have a soft spot for the model 11's??  LOL

That Model 11

Is a workhorse!

I'm guessing the grease has hardened over the centuries into a dangerously solid mass.

Along with the rest of kitchen small appliances were and still are the gift of choice for weddings, new house warming, marriage anniversaries, birthdays (wives and mothers), and so forth. As such many women of the Baby Boom years, and their mothers have spares in spades stashed away. *LOL*

Such an Awesome Find!

Congratulations in acquiring a Model 11 Mixmaster! New in the box finds are a rare find, I have a much newer Sunbeam Mixmaster 701-10D that was a NIB find too and it was my second one. The first one I had drove to Houston to in search of a refurbished model that were sold at the Sunbeam Appliance Repair centers. That was back in 1979. There were Repair Centers in Baton Rouge and New Orleans as well but at the time of my visits there, they had no chrome mixers for sale.

I wonder why the Model 11 had such a short production run. When Consumer Reports tested stand mixers in 1956, both Mixmaster Model 11 samples had developed seized bearings during the endurance test. A third mixer was tested and struggled to finish the endurance test as well. CU rated the mixer unacceptable. At that time, recalls were unheard of and it could have possibly bankrupted Sunbeam and really damage their reputation of quality at that time! Ivar Jepson, the creator of the Mixmaster was still with Sunbeam at that time. I am sure there are others that wonder why the Model 11 has such a short production run too. the last MixMaster, Jepson was involved with creating, was the Model 12 and it also had the longest production run, 10 years. Sunbeam also created and sold other less expensive stand mixers offering the 3 speed HMS and the 12 speed EM. I suspect this was done because Dormeyer was doing this and Sunbeam was in fear of losing sales. In 1956, Hamilton Beach introduced their Model H, a far more attractive mixer than their former Model G. Hamilton Beach and Dormeyer also had mixers with stainless steel bowls around 1956. Chrome finishes and stainless steel bowl raised the price about 10 dollars, which was a lot of money, when you consider wages in the mid-1950s. There was a lot of magazine small appliance advertising at this time with some very appealing ads. The Model 12 introduction I suspect, was meant to insure for Sunbeam remain the leader in stand mixer sales. A KitchenAid in comparison, was too expensive at the time for most people to consider.

Interesting how that has changed too.

I have

All the colors of 11s and 12s, I love them all, all my 11s run fine, the only problem with any of the old Sunbeams is a tendency to run slower as they age, especially the portables,the J and the HM are kind of pitiful as is the early Hamilton Beach Mixette,To find a new 11 is fantastic, I have a NIB EM.

So I got the gearcase re greased, The unit is running as we speak. My only concern is that at full speed, it doesnt seem to be a consistent high speed. I pulled the motor out and cleaned up the part where the brushes touch, and I lubed everything. Nothing is mechanically binding at this point.

All I can think of is maybe the capacitor is weak, or the reostat thingy is not behaving properly. Looking for a bit of advice.

While the capacitor is definitely at the end of its life...

It's possible that the brushes have not run in yet. I'd let it run at various 'speeds' for a couple of uses and see if that doesn't seat them.

If not, perhaps the governor is binding?

Post# 931241 , Reply# 13   4/8/2017 at 10:59 by Lorainfurniture (Cleveland )        

Governor is free, the unit is like new in and out. I oiled up everything, the governor spring moves very well. I ran the unit for about an hour, it just seems like the speed fluctuated for no apparent reason. The "reostat" seems deteriorated a bit, the cap is likely a run capacitor, maybe that's the culprit. Anyone know of a plug and play new replacement?
