Check the Door Lock
Step 1: Check the resistance between Pin 2 and Pin 3
with the Slipper Held right as figure below. It should be in
range from 30 to 100Ω. Otherwise, the lock is failure.
Step 2: Hold the Locker Slip Left as figure above. Give a
power pulse to the Lock between Pin 2 and Pin 3. Then
release the Slipper. It should take the place without any
movement. Otherwise, the lock is failure.
NOTE: The power pulse to the Lock should be less
than ONE second. Otherwise, it will be damaged.
Step 3: Give a power pulse to the Lock between Pin 2
and Pin 3 again. The slipper should move back to its
original place immediately. Otherwise, the lock is failure.
Now, the lock can be confirmed OK.
Replace the PCBs.
