Call, describe what the door is doing, and one of our local garage door professionals will take it from there. There is no form, email or text option.
Say first: the address, whether the door is open, closed or partly open, and what happened first.
Then give: the spring type if you can see it, the door width, the opener brand and what the sensor lights are doing.
Ask your technician: whether there is a trip or diagnostic charge, when the visit will be and what the warranty covers. The before-you-call list has the full checklist.
