Oven wouldn't turn on, screen said F2E1

The kitchenaid warranty is exactly 365 days from date of registration "No Questions Asked" on day 366 you have no warranty and you gotta pay.
Now the good news; first check the wall socket, I know it works but check it anyway. then check your plug, did you step on it while you were working on the machine? The plug often falls to the floor during work and can get underfoot, you may have broken the plug it'self. next you will need a parts list for your model from Kitchenaid's website.

My first suggestion is to try a minor adjustment of the speed control switch, they often get out of sync when you do something to the machine. You can find several videos of this on the youtube site. "Adjusting the speed control switch on kitchenaid mixer"
If the two or one of the top 2 screws on the speed control switch move it can shut the machine down just like an on/off switch. Did you remove the back cover during your adjustments? Did you remove and replace the carbon brushes on the side of the machine while working on the machine? If you did you might have put them back in incorrectly, if you did they will also act a a shutoff switch. If you did not take them out then DON"T as there are four ways to put the brushes back in and only one way is correct and there are two brushes to deal with. Has work ever been performed on the mixer before? Because if all you did was to adjjust the beater height screw then nothing should have effected the normal operation of the mixer. So if there is anything that you did but did not include in your description of work you performed then please let us know. We strive to give accurate solutions but... as I am a KA tech I do not have any other solutions with out the machine in front of me. Just so you know you can fix this yourself.

If the mixer died completely and no noise at all comes from the machine you need one of three things.
1. New brushes2. new speed control switch3. a new motor.

The KP26 is a 6 quart mixer of the new design, post 2002, it is easy to work on and relatively inexpensive for parts if it turns out to be the motor that will be about $100.00, the speed control about 30.00, the brushes on this mixer cannot be replaced you have to install a new motor, sry about that. Hope this helps let us know. But first check that the electric outlet you are working from has not tripped the breaker on the circuit too. I know I know it's silly to say but check the outlet first before you spend a dime on anything.

I took mine apart completely and reassembled everything and greased everything and mine is doing the same thing. I'm thinking, also, that it is the tightening of the top lock nut.

If you have already fixed the problem then great and I'm sorry that i didn't see it sooner. If you have not then do this first. BTW if you are under warranty this WILL NOT VOID the warranty.

Solution 1; There is a silver ring around the front of the mixer that you attach your beater or whip to. Take a nonmetalic hammer and a screw driver, place the screwdriver on the top edge of the ring and tap LIGHTLY on the screwdriver. The ring will fall off after a couple taps. DO NOT hit it hard, you can scratch the finish all the way down to the raw Zinc frame and you can knock the ring out of round. The ring is only held on by pressure so if you knock the ring out of round it will not stay on anymore. Onward and upward...turn the mixer upside down (On a Towel or you will scratch the finish) and you will see five screws that are now exposed tighten them down again. They won't turn much so don't worry it only requires about a 16th. of a turn. What you have just done is to tighten up the two parts of the mixer and apply pressure to the gasket / seal that hold the gear head grease in. While you have the mixer in this position (you have probably figured it out by now that someone else is holding the mixer upright while your working on it) you will find 4 more screws that attach to the mixer toward the rear. Give them a little tighten turn also. Now take the silver ring and place it back where you took it off from and tap it back into place. This ring is held in place by pressure only. If you find that the ring is not going on not to worry. You can give it a good whack as long as you hit straight down. If you knock it sideways you can knock the ring out of round and then it will never stay up again. So be careful with the hammer. If you look closely at the inside of the ring you will see what may be called "Stretch Marks" from where the ring was originally move it past those marks and tap it on. going back to the original stretch marks does not always work and the ring falls of so choose a new position for putting the ring back on.


Solution 2 THIS WILL VOID YOUR WARRANTY. If you proceed with this step and your mixer is under warranty you will void the remaining time on your warranty and you will be doing a basic tear down of your mixer. So first you need to order two parts, a gasket and some food safe grease. do a search for kitchenaid grease and kitchenaid gasket and you will find both at several sites including Amazon, so check pricing and shipping as both vary widely between sites. The next thing to do is go to kitchenaid.com and download a parts list for your mixer by clicking on the support tab and then click on download manuals and user guides. This will give you a working diagram of your mixer so that you can follow along with your work. The next thing to do is go out on the internet and search for a video that is out there that will walk you through it step by step. Change grease in kitchenaid mixer will take you there. To do a write up step by step would take a long time and a lot of space. It is basically eleven separate steps of dissassembly to get to the gear case grease then you have to clean out the old and re-pack with new grease and put it all back together. during the process you can knock your mixer out of "Speed" and then you have to re- tune the mixer speed. again, not hard but another step to do and there is a video on the internet for that too. You can check with Kitchenaid Customer Service and they will put you on to the nearest Factory authorized sevice center, If you are close you can drop it off if it is far away you will have to ship. the mixer weighs 25-30 pounds and will cost $25-30 dollars to ship. they will get return shipping. the cost of the re-pack also varies by state and location. In Orlando Florida it costs $110.00 to have it done plus shipping. In Miami if you haggle you can get it for $90.00 and if you don't have to ship at all it will be less. the job is not hard but it will require your time (2 Hours for the novice) and lots of patience and a work area that you don't mind getting dirty. DO NOT do this on your wife's kitchen table she WILL shoot you when the grease gets all over the place. good luck.

I am not sure what has happened to your mixer but, select
different speeds from Stir to 10. If it runs OK, then there is
nothing to worry about, otherwise do the following to re-adjust the mixer's speeds:

Get a copy of the Repair Part List of your model from Kitchenaid.com
Remove the screw holding the End Cover and locate the three screws from the Control Plate.
All three (2 top left and right, and 1 bottom) must be adjusted.

1. Loosen the lock nuts enough & Turn the 2 top screws clockwise until they cannot be turned
anymore. Leave the bottom screw alone for now.
2. Use a dab of white paint or paper whiteout to mark the positions of the Phillips screws.
3. Plug in your mixer and Set the speed selector to "Stir".
4. Turn each top screw One full turn couterclockwise (alternating between Left and Right)
Keep making one full turn at the time (for both left and right) until the motor starts running.
5. Put your hand near the Agitator shaft and allow it to brush your finger slightly. Use your
watch or clock and start counting the number of times the shaft touches your finger in
60 seconds. The correct count should be 60 RPM (Rounds Per Minute). If it is less
or more than 60, give each screw 1/4 turn counterclockwise or clockwise and start counting
again. Now tighten both lock nuts.
6. Set the speed selector to "6" and turn the bottom screw either clockwise or counterclockwise
to achieve a speed of 180 RPM.
For your reference, the planetary RPM's for the 5-qt. tilt-head Artisan Stand Mixer are as follows:

Stir speed - 60
Speed 2 - 95
Speed 4 - 135
Speed 6 - 180
Speed 8 - 225
Speed 10 - 280

Don't worry about the Worm Gear for now. You have to make sure that the Motor
is fully functional by itself: Remove the Transmission Housing Cover (4 screws) and
the two screws holding the Motor down. Lift the Motor off the Worm Gear and set it
on the side (be careful of AC voltages from the Motor and Control Assembly).
Select Stir setting and observe the motor shaft. Is the Motor running? If it is,
Select other speeds to see how the motor performs.
With the motor now fully functional, you can now check the Worm Gear Follower
for worn out/broken teeth. Remember the motor drives the Worm Gear, it then in
turn drives the Worm Gear Follower (you may have to remove the grease to see it)
The Bevel Gear sits right on top of the Follower and drives the Attachment Gear.

Two things you can do for a 24-year old machine:

1. Replace both motor brushes (Black large plastic Caps on each side
of the Moto Housing). Without these, the motor wouldn't even run.
2. Replace the Worm Gear (the cause of the Rough Loud noises)

your model KSM90.

Also don't forget to tighten all the screws inside the mixers and use
fresh Kitchenaid Grade Food Grease for all the gears.

Unfortunately, the Kenmore mixer sounds louder than freight train due to a poor planetary gear design. I had to take mine back so that the neighbors wouldn't **** me. I hooked up two identical models at the store to get the same, painfully loud, experience. I think I prefer the sound of a bandsaw to the grating noise it produced.
