In reply to purplemonkeyelephant:
The only electric opening metal doors I’ve seen have had their own frame of metal and there was always a gap to deal with the expansion. I guess yours doesn’t and it’s metal closing directly on wood?
If no metal frame, with a wooden garage I wouldn’t be surprised if the whole garage has shifted say with the high winds we have had, or just water penetration, and that is jamming the door. Check the garage all round as to any change in direction or warping of frame (get your spirit level out as it could be subtle). Check if there are uneven gaps around the frame (or none at all in places). Even if the door has it’s own frame has the garage shifted to twist or put a torque strain the frame?
With wooden structures, depending on type and quality of wood there is scope for significant movement with weather IME. My back door for example expands and contracts and it’s depth changes by some 2mm with weather which makes it tight to lock/unlock at times and loose at others.
With the electric mechanism, are there any locking mechanisms for extra security that may have “tripped” into operation? Mine for example has two extra locking points that normally are always open/not used, but could in theory engage if a fault. I wouldn’t be able ever to open my door if they tripped without using a manual override procedure. The are there for if power goes off and the door needs to be locked securely.
