The Arm-A-Dor needs to be reset. The Arm-A-Dor unit is having an issue with one of it's microswitches.
Please reset the Arm-A-Dor unit. There are three microswitches that need to be examined. One under each end cap and one on the sub assembly next to the circuit board. Check and make sure the the end cap microswitches are not broken. Remove the push bar to check the last microswitch next to the circuit board. If the microswitch is good make sure that the switch actuator is properly engaging when the door is in the locked position.
