For a few days there was a grinding sound whenever the door started moving. Now the motor spins freely and the door stays exactly where it is.
The motor runs, you can hear it working, but the door never moves. When you look up, the sprocket on top of the head is barely turning, and there is a little drift of pale plastic dust on the cover.
Press the remote and the motor runs its full cycle, lights on, the usual whir, but the door does not move a centimetre. Up at the trolley, the belt is hanging loose where a small plastic clip used to hold it.
You want the ceiling back. A storage loft, a vehicle lift or kayak racks would fit if the long rail and motor box were not hanging in the middle of the garage, and the low ceiling of an older house leaves little room for the standard rail anyway.
On bright mornings the door will not close, then by lunchtime it behaves itself. The garage faces the low sun, and the light reaches straight across the floor to one of the little black sensors.
The remote opens the door only when you are almost underneath it. From the end of the driveway you press five or six times and nothing happens.
There is a wireless symbol printed on the opener above the car, and the manual mentions an app, but the head unit has never been connected to anything. You downloaded the app once, it asked for a serial number and a network, and the moment passed.
Your garage is detached and has no side door. The remote is dead, the keypad is dead, and the small round lock in the top panel is meant to be your way in.
