August Lock: Troubleshooting a Grinding Motor Sound -... | digitalhomefaults.org

Technical Background:

The August Lock uses a DC motor to drive a worm gear, which in turn rotates the deadbolt. Motor current is regulated by a microcontroller based on feedback from position sensors. Zigbee or Wi-Fi protocols facilitate communication with the August Connect or integrated hub. Cold weather significantly increases battery impedance and lubricant viscosity.

Symptoms:

Motor emits a grinding noise during lock/unlock operation. LED may flash red indicating obstruction or low power. App may report "Motor Error" or "Calibration Failed". Physical resistance felt when manually operating the lock.

Possible Causes:

Mechanical binding of the deadbolt due to warped door frame (seasonal changes).
Insufficient battery voltage under load, especially in cold Canadian winters.
Stripped gears within the motor assembly.
Obstruction preventing free movement of the deadbolt (ice, debris).
Weakening or degradation of the motor drive circuit components.
RF interference causing communication errors and erratic motor behavior (900MHz/2.4GHz).

Solution:

1

Replace batteries with fresh lithium AA batteries, ensuring correct polarity. Verify voltage under load (should not drop below 1.3V per battery). Pre-heat the batteries indoors before installation if temperatures are below -20°C.
2

Inspect the deadbolt and strike plate for proper alignment. Adjust strike plate position if necessary to eliminate binding. Use a file to smooth any rough edges. Consider a longer strike plate screw to increase security.
3

Clean the deadbolt and surrounding area to remove any debris or ice. Apply a small amount of silicone-based lubricant to the deadbolt mechanism. Avoid petroleum-based lubricants as they can attract dirt.
4

Check for RF interference using a Wi-Fi analyzer app. Identify and mitigate sources of interference (e.g., cordless phones, microwave ovens). Consider relocating the August Connect or hub for improved signal strength.
5

Perform a lock recalibration through the August app. Follow the on-screen instructions carefully.
6

If the grinding sound persists, the motor assembly may need replacement. Contact August support or a qualified locksmith.
7

For users with Bell Giga Hubs, ensure the 2.4GHz Wi-Fi channel is set to 1, 6, or 11 to minimize interference.

Safety Warning:

Do not attempt to disassemble the August Lock motor assembly unless you are a qualified technician. Lithium batteries can pose a fire hazard if mishandled. Ensure proper disposal of used batteries. Protect your August account with a strong password and enable two-factor authentication to prevent unauthorized access.

Prevention:

- Replace batteries annually, preferably before the onset of winter. Use high-quality lithium batteries. - Regularly inspect and lubricate the deadbolt mechanism. - Periodically recalibrate the lock through the August app. - Monitor battery health in the August app and replace batteries proactively. - Ensure the August Connect or hub has a strong and stable Wi-Fi connection.

Expert Tip:

If experiencing intermittent motor issues, try performing a three-tap reset by quickly tapping the August logo three times. This can sometimes resolve minor software glitches and recalibrate the motor position.

Frequently Asked Questions

•How do I check the battery voltage in my August Lock?

Use a multimeter to measure the voltage of each battery under load (while the motor is attempting to operate). A healthy battery should maintain a voltage of at least 1.3V.

•Where can I buy replacement parts for my August Lock?

Contact August support directly or search for authorized retailers online. Ensure you purchase genuine August parts to maintain warranty coverage.

•What type of lubricant should I use on my deadbolt?

Use a silicone-based lubricant, as it is less likely to attract dirt and debris compared to petroleum-based lubricants. Avoid using WD-40.
