Door does not lock
Check to make sure the wires are securely tightened to the terminal block.
Check that the power supply is connected and operating.
Use a multimeter to check the resistance of coils inside the lock. See below.
Make sure the rubber washer is installed and free from damage.
Door locks, but can easily be forced open
Make sure the electromagnet and armature plate are properly aligned.
Make sure the contact surfaces of the electromagnet and armature
plate are clean and free from rust.
Check the power leads with a multimeter to see if 12 or 24VDC is present.
Use a multimeter to check the resistance of coils inside the lock. See below.
Make sure the rubber washer is installed and free from damage.
Check Voltage Selection Jumper for correct setting.
The electromagnet is fitted with a metal oxide varistor to prevent
interference, so do not install a second diode.

1.
Remove the faceplate from the lock.
2.
Disconnect the wire harness from the circuit board.
3.
Using a multimeter, measure the resistance across:
Red/Green wires, and the Black/White wires.
4.
Each coil should test at
57
±10%.
5.
If one or both of coils shows an open, short, or incorrect
resistance, replace the electromagnet.
