sticking garage door

[knowlittle]

Electrical garage doors stick when opening but only in cold or freezing weather all equipment has been greased and free to run, any idea's how to fix.

It freezes because it's very cold. I suggest you throw a wool blanket over it to help keep it warm.

In a more useful vein... allowing for differences in construction, our double overhead (as they're called here in the U.S.) doors require adjustment of the guide rails at the sides (where the rollers run) about each two years or so. You can do it yourself by simply having someone raise the door slowly in manual mode (disconnecting the drive mechanism) and seeing where the rollers bind up as they go up and down. The rollers adjust in and out in their mounting brackets (on the door itself). Sometimes the rails need to be adjusted by loosening them from the garage overhead and retightening when they are level and straight. Levelling is done with a common carpenter's level (the level,not the carpenter being common) and the straightness is done with a chalk line attached to the front of the garage and the other end to the opposite side of the garage (more easily demonstrated than explained) at equal measured distances from a common point.
At any rate, the frequent lubrication can't hurt, but try using a good spray or dry graphite lubricant.
By the way, depending on the spring mechanism, the door should balance about half way up when disconnected from the drive mechanism... this is maintained by adjustment of the spring tension, but this can actually be a dangerous task if you're not familiar with it... most garage door companies provide this service for a reasonable charge... Best of luck!
