A properly working garage door is vital for the opener to work effectively. Therefore, it is important to test the two mechanisms independently (garage door opener and garage door) to fully determine the status of the opener.
A slow-moving garage door or loud, obnoxious door are pretty clear signs that your motor is going bad. Electric motors get really loud when they near their end. A garage door motor change will usually quiet things down, but sometimes the entire assembly will need replacing.
If a new motor doesn’t resolve your problems or you need a second opinion before you buy a new system, please contact your local garage door experts.
