KitchenAid speed controller replacement
When the mixer only runs flat out, ignores the speed dial, or will not switch off, the speed controller has failed.

Does this sound familiar?
- The mixer runs at full speed no matter where the dial is set
- Only one speed works, or nothing happens at the low settings
- The mixer keeps running after you switch it off
- The speed surges or drifts on its own while mixing
What the repair includes
- Controller tested and the fault confirmed
- Failed speed controller replaced
- Every speed setting checked against the dial after reassembly
- Full run test before the mixer comes back
The speed controller is the board that reads the dial and tells the motor how fast to spin. It is a common failure point on older mixers, and it usually announces itself by refusing to hold a speed.
A mixer that only runs flat out is worth fixing quickly. Running at full speed hammers the gearbox and heats the grease, so a controller fault left alone tends to take gears with it.
I replace the controller, then run the mixer through every setting on the dial so you get it back working the way it should across the whole range.

Common questions
Will a new controller fix every speed problem?
Not always. A mixer that will not turn on at all can be a cord, a switch or a motor fault. If I find something different during the repair I will call you before doing any extra work.
