August Lock Motor Errors: Screws Too Tight - Smart Home | digitalhomefaults.org

Technical Background:

The August Lock uses a DC motor and gearbox to extend/retract the deadbolt. Mechanical binding increases the motor's load. Overtightening the mounting screws deforms the lock housing and internal mechanisms, increasing friction. Incorrect alignment affects motor power draw. The control circuit monitors motor current and throws an error if it exceeds a threshold. RF communication is typically Bluetooth LE, but is not the root cause.

Symptoms:

The August Lock motor struggles to actuate the deadbolt. Error messages appear in the August app indicating motor overload or obstruction. The lock may intermittently fail to lock or unlock. Audible grinding or straining noises are present during operation. LED indicator displays a red flashing pattern during attempted operation.

Possible Causes:

Excessive screw torque during system, deforming the lock housing.
Door frame warping due to seasonal temperature fluctuations (-20°C to -40°C) causing binding between the deadbolt and strike plate.
Misalignment of the August Lock with the existing deadbolt mechanism.
Stripped screw threads preventing proper torque application and causing instability.
Incorrect deadbolt cylinder depth or type.
Foreign object obstruction within the lock mechanism.

Solution:

1

Loosen all mounting screws on the August Lock by approximately 1/4 turn. Test lock operation after each screw adjustment. Use a calibrated torque screwdriver set to the manufacturer's recommended value (typically 2-3 in-lbs).
2

Inspect the door frame and strike plate for signs of warping or misalignment. Adjust the strike plate position as necessary to ensure smooth deadbolt operation. Consider using a shim if the frame is significantly warped.
3

Verify the deadbolt cylinder is the correct length for the door thickness. A cylinder that is too long or too short can cause binding.
4

Lubricate the deadbolt mechanism with a silicone-based lubricant specifically designed for locks. Avoid using petroleum-based lubricants, which can attract dust and grime.
5

Check the battery voltage under load. Use a multimeter to measure the voltage while the lock is attempting to actuate the deadbolt. Replace batteries if voltage drops below 4.5V for a 6V system (4xAA).
6

If the problem persists, remove the August Lock and manually operate the deadbolt. If the deadbolt operates smoothly, the issue is within the August Lock mechanism. Contact August support for warranty assistance.
7

Ensure the August Lock is running the latest firmware. Check for updates in the August app.

Safety Warning:

Data privacy is paramount. Securely store all access credentials. Avoid sharing credentials with unauthorized users. Protect the August Lock from physical tampering to prevent unauthorized access. If using a rechargeable battery pack, ensure it is certified to Canadian safety standards (CSA/ULC). Lithium battery malfunctions can cause fires.

Prevention:

- Use a torque screwdriver to avoid overtightening the mounting screws during installation. - Periodically inspect the door frame and strike plate for signs of warping or misalignment, especially after extreme temperature changes. - Check the batteries annually, ideally before the onset of winter. - Clean and lubricate the deadbolt mechanism every six months. - Monitor the August app for firmware updates and install them promptly.

Expert Tip:

Before re-tightening any screws, manually push the August Lock housing flush against the door surface. This can help alleviate stress on the internal motor mechanism and prevent binding. A small shim behind the August Lock can sometimes improve alignment. If you are using a Bell Giga Hub, ensure the 2.4GHz Wi-Fi channel is set to 1, 6, or 11 to minimize interference with Bluetooth LE.

Frequently Asked Questions

•What is the recommended torque setting for the August Lock mounting screws?

Typically 2-3 in-lbs. Refer to the manufacturer's instructions.

•What type of lubricant should I use on the deadbolt mechanism?

Use a silicone-based lubricant specifically designed for locks. Avoid petroleum-based lubricants.

•How do I check the battery voltage under load?

Use a multimeter to measure the voltage while the lock is attempting to actuate the deadbolt. Battery voltage should not drop below 4.5V for a 6V system.
