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.
old stand mixer mixing bowl base will not firmly hold newer mixing bowls
With a screw driver remove the screws holding the old base in place. With a flat head screw driver carefully pry and remove old mixer base. With 600 grit sandpaper clean and make smooth any burrs or rough spots in the mixer base recessed area. You can use some light grease and coat the outer edges of new mixer base and place in the now cleaned mixer base recessed area. The new base maybe a tight fit and not be fully seated in the recess. If a tight fit, place the piece of 2x4 piece of wood over the new part that is in the recess and carefully tap the base home using the sledge hammer. Check to see, if the base is fully seated. If not fully seated, tap again When fully seated replace the screws. You may have to adjust the height of the stand mixer head with mixer paddle attached for proper clearance between bowl and paddle. See your mixer manual for adjustment procedure
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 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!
I replaced the phase control board because the mixer had only one speed and was surging. I noticed from other posts that it is important to note the setting of the speed plate before you remove it in order to remove the phase control board. Also be careful removing the associated 'slip-on' terminals as it would be easy to damage the speed plate. If I ever do this again I will go ahead and replace the speed plate, probably the cheapest item to replace. The operation was a success and the mixer is back in business. Thanks.
Simple fix actually. UNPLUG mixer and remove the one screw on top that holds on the back. The Phase control board sits under and behind the paper insulator and "switch" assy. Remove the 4 wires with a pair of needle nose pliers, the one screw holding it to the back of the mixer and install the new one in reverse order.
I watched a YouTube video all the way through, then watched each segment and followed along with the video. It was messier than the professional repair guy, but it worked out fine. This is not a difficult repair when you can watch a video and follow along. It saved me about $130.
short in the wiring had blown the ground plug out,,,contact with a mounting screw head
had to replace the outlet strip and relocate the mounting screw,,,,wiring cord to the mixer was super correct and had to simply follow basic wiring (black to black,,,silver to silver,,,green to ground) ,,, the cord came with the correct mounting bushing already on the cord. Thx a bunch!
The mixer would not spin so I assumed it was a bad worm gear
I watched a video on how to replace the worm gear. When I opened the mixer I noticed a small screw laying in the grease. I removed as much grease as I could and could not find anywhere that the screw would have come from. All the gears turned and looked fine so I replaced the grease put the mixer back together and it worked fine. I am thinking the small screw must have somehow fallen into the mixer when manufactured. So proud of my 70 year old self for getting the job done.
The white enamel coating was breaking off the mixer beater. There was a scrapimg noise when the beater was in motion.
I simply inserted the new beater into the mixer to see if it scraped the sides of the bowl. It fit perfectly and didn't scrape the bowl like the old one did.
