Masseuse Ultimate Chiro - Troubleshooting: Kneading;Tapping Motor Malfunction - Initial Diagnosis; Motor Failure Analysis and Elimination; Wire Harness and Main Board Checks

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 30～80Ω ，if not between 30～80Ω , need change motor.
