You can lubricate a screw drive garage door's mechanism using a silicone lubricant. Lithium-based grease can also be used, but it attracts dirt and may need to be cleaned off and reapplied more often. Here's how to lubricate a screw drive garage door:
- Disconnect the garage door from its power source. This is important to prevent the door from moving while you are lubricating it.
- Open the garage door manually. This will allow you to access the mechanism that needs to be lubricated.
- Locate the screw drive. It is usually located at the top of the garage door, near the motor.
- Apply the lubricant to the screw drive. Use a small amount of lubricant, and be careful not to get any on the door itself.
- Open and close the garage door several times. This will help to distribute the lubricant and ensure that it reaches all of the moving parts.
- Reconnect the garage door to its power source.
Here are some additional tips for lubricating a screw drive garage door:
- Do not over-lubricate the door. This can cause the door to become sticky and difficult to operate.
- Lubricate the door at least once a year, or more often if the door is used frequently.
- If the door is making any unusual noises, it may be a sign that it needs to be lubricated.
