Use proper toolsPrevent damage to components and housing
Keep organizedLabel screws and parts during disassembly
Avoid water contactKeep electrical components dry
Check for warrantyVoid warranty if opened by unauthorized personnel

Tools Required

Essential tools for Kenwood mixer repairs.

  1. Torx screwdrivers (T10, T15, T20)
  2. Phillips screwdrivers (#1, #2)
  3. Flathead screwdriver
  4. Needle-nose pliers
  5. Multimeter for electrical testing

Common Issues & Symptoms

Typical problems encountered with Kenwood mixers and their indicators.

  1. Motor not starting: Check power cord, speed control board, brushes
  2. Unusual noises: Inspect gears, bearings, motor assembly
  3. Speed inconsistency: Test speed control module, motor brushes
  4. Overheating: Clean ventilation, check motor load, inspect bearings
  5. Attachment not working: Examine drive mechanism, coupling

CAUTION! Always diagnose thoroughly before disassembly to avoid unnecessary repairs.

Disassembly Procedures

Motor Replacement

Procedure for replacing faulty motor in Kenwood mixers.

Identification: Check model number (KM020, KM336, etc.) for correct replacement motor.

Removal: Disconnect power wires, remove mounting brackets, extract motor assembly. Installation: Align new motor, secure mounting, reconnect wires following original routing. Testing: Run briefly without load before full reassembly.

Gear System Repair

Repairing and replacing worn gears in transmission system.

  1. Remove gear housing cover
  2. Inspect all gears for wear, chipping, or missing teeth
  3. Clean old grease from housing
  4. Replace damaged gears with OEM parts
  5. Apply food-grade grease to all moving parts
  6. Reassemble housing ensuring proper gear alignment

Tip: Take photos during disassembly for reference during reassembly.

Speed Control Issues

Troubleshooting and repairing speed control problems.

  1. Test speed control board with multimeter
  2. Check variable resistor for consistent resistance
  3. Inspect wiring connections for corrosion or damage
  4. Replace faulty speed control module if necessary
  5. Test all speed settings after repair
  6. Ensure proper heat sink contact for power transistors

WARNING! High voltage present - discharge capacitors before working on control board.

Beater & Attachment Problems

Fixing issues with mixer attachments and beaters.

ProblemCauseSolution
Attachment not rotatingWorn drive couplingReplace drive coupling mechanism
Beater wobblingBent shaft or worn bearingsReplace beater shaft assembly
Difficulty attaching bowlsMisaligned locking mechanismAdjust or replace locking pins
Attachments falling offWorn retention springsReplace attachment springs

Electrical Testing

Using multimeter to diagnose electrical issues.

Continuity testing: Check power cord, switches, thermal cutouts. Resistance testing: Measure motor windings, speed control components. Voltage testing: Verify proper voltage at motor terminals during operation.

Reassembly Guide

Proper reassembly procedure after repairs.

  1. Clean all components before reassembly
  2. Follow disassembly photos in reverse order
  3. Ensure all wires are properly routed
  4. Check gear alignment before securing housing
  5. Test function before final screw tightening
  6. Verify smooth operation of all controls

CAUTION! Do not force components during reassembly - check for proper alignment.
