Garage door opener loud grinding noise issue

[FatimaandAhmed]

Hi all!

What could cause a garage door opener to make a loud grinding noise during operation, even if the door seems to function normally? It's a screw drive model, and the door appears balanced. Any ideas on what might be the issue and how to address it?

Hi, here's what you can try:

1. Lubricate the screw drive. Use a silicone-based lubricant made for garage doors.

2. Check the trolley nut (the part that moves along the threaded rod). If it looks worn out, it might need replacing.

3. Clean out any dirt or debris you can see in the mechanism.

4. Look to see if anything seems out of alignment.

The grinding noise is annoying, but at least your door is still working. That's a good sign. Start with these simple steps, and hopefully, that'll quiet things down. Let me know if you need any further assistance.
