With the mixer being over 30 years old we believed it has going to have to be replaced. However, my husband jumped on uTube and looked at reviews for the problem. Motor was only running on high speed. Reviews said to replace the phase control board. Repair was very quick by just taking off the cover. Removing the old board and connecting the new. Mixer is working awesome once again. In such a disposable society it is great to be able to fix vs trash. Happy Baker.
The mixer broke the worm gear(the only plastic gear inside the mixer) and needed replaced.
I took apart the mixer housing and removed all the screws. The most difficult part was the two pins that needed to be removed with a metal punch. They were in fairly tight. The mixer came apart pretty easily and it was obvious which part needed to be replaced as it was broken and missing teeth. After replacing the gear and applying new grease for smooth operation, I simply put it back together and it has worked like new ever since.
You tube has great instructions! I would suggest when you buy a part to let customer know that they need a food grade gear grease ordered to complete the reinstall of all gears and body parts!
SPEED WENT CRAZY, VERY VERY FAST. NO CONTROL AT ALL EXCEPT OFF
INSTALLED PHASE CONTROL BOARD AND SPEED CONTROL PLATE, BOTH AT SAME TIME Your DYI video was helpful, especially holding the spring with a cloth. Also good for fine tuning to get the speed exact
I am not handy, but was able to follow this YouTube video and do this repair easily and successfully: https://www.youtube.com/watch?v=1QsgPIL9FpA
I did take the mixer apart first to verify that the worm gear was the issue, then ordered the part from you site. I received it quickly and was able to do the repair and get back to mixing in a few days!
Plastic worm gear gave way (as designed) when the grain mill over-worked it.
I did exactly what the PartSelect video demonstrated after watching other DIY videos on the Internet, thus I did not remove the stand which seemed like a little too much for a simple straight forward repair. This is the second time I have replaced this gear. The first time was about 10 years ago when the bakelite gear broke on a 30 year old KitchenAid K -45. That mixer made hundreds of loaves of bread after grinding many pounds of wheat berries. The only reason we had to replace it was that it walked off the flour dusted counter and landed on its head when my wife had her back turned. Otherwise we would still be using it. :-) Thanks for the excellent service and instructions.
The shield works sufficiently. Note that the shield is not a continuous circle as shown in the picture. This actually can be an asset because it can be installed or disassembled without stopping the mixer of having to lift the head while running.
Damaged gears in both machines. Been setting around for a few years broken. Gears broke way too soon.
Simply removed damaged gears. Very simple to do. Ordered gears. Replaced gears. Both working well ( so far. ) Machines are easy to dismantle. Just be sure to put the screws back in the holes you took them out of when dismantling...no lost screws. On the smaller model, took pictures of the wire positions to be sure they were replaced in the proper order. Larger model had no wires to remove.
