Vibrator Troubleshooting
• Check that the vibrator motor is seated properly (correct alignment and
pads are not lifted) and the counter weight is not bent and can rotate
freely.
Measure the resistance across the vibrator, it should be 14ohms +/-
•
4ohms.
Check that E5101 and E5102 are not skewed or damaged.
•
• Check C5105, C5106, C5107 for damage or any process related
defects.
• Check the motor itself by applying 2.4V across the C5105, it should spin
freely and continuously. If the motor spins when 2.4V is applied
externally, but not when driven from CQA app, x-ray U5101 for defects
and replace as needed.
NOTE: If motor does not spin, or if motor stutters, but starts working
normally after turning it manually, it has a "dead-spot". Consider it a
failure and replace the motor.
