The door has come off its track, or hangs out of line
Why it happens
The door runs on rollers that sit inside a track on each side. A roller that jumps out, or a track that gets knocked out of line, stops the door running true.
Why it matters
A door hanging off its track can drop or jam, and running the opener can make the damage worse. It counts as an emergency.
Response
Stop using the opener and keep clear. Thom takes emergency callouts around the clock, and roller and track lubrication is part of every service.
