IV. Troubleshoot 2--- Kneading/Tapping motor not work
▲
Analysis reasons why Kneading/Tapping motor not work
1. Motor failure
2. Wire harness not connect well
3. Main board failure
▲
Specific Troubleshoot Analysis and elimination
1. Motor failure Analysis and elimination
Because of motor coil open circuit led to even the driver Board under a DC24V power supply , the motor still not functioning
，
Can use
form 1 as reference, measure the motor resistance if between 30
～
80
Ω
，
if not between 30
～
80
Ω , need change motor
