Tachometer Error

High severityExpert Guide

What Your Machine Is Actually Telling You

F06 means the MCU isn't getting valid speed signals from the motor's tachometer. The tachometer generates voltage proportional to motor speed — no signal means the MCU is blind.

Common causes:
1. Loose motor connector (30%).
2. Tachometer failed (20%).
3. Carbon brushes worn (15%).
4. MCU board (15%).
5. Wiring (10%).
6. Motor winding (10%).

What You're Probably Seeing Right Now

  • Motor won't start or starts then stops.
  • Motor hums but doesn't spin.
  • F06 only during spin.
  • F06 appeared suddenly.

DIY Fix — From Easiest to Hardest

1

Power Reset (5 minutes)

1. Unplug 5 minutes.
2. Test with small load.
2

Check Motor Connector (10 minutes — Fixes 30%)

1. Unplug.
2. Access motor.
3. Reseat connector firmly.
4. Check for burned pins.
3

Test Tachometer (5 minutes)

1. Disconnect tach leads.
2. Measure: 100-300Ω = good. OL = dead.
3. Replace: $15-30.
4

Check Carbon Brushes (5 minutes)

1. Remove brushes.
2. Minimum length: 15mm.
3. Shorter = replace ($10-25 pair).
5

Test Motor Windings (5 minutes)

1. Measure: 2-8Ω.
2. Ground test: must be OL.
3. Replace motor if failed ($80-200).

When to Call a Pro

  • Motor — $150-$350 installed.
  • MCU board — $120-$300.
  • Brushes + tach — $80-$200.
