Do not, I repeat NOT grease your garage door. Trust me - it gets too cold here in the winter for the grease to do anything but turn into tarry glue. Then, because I'm a door nut, I make money. Maybe you call my competition and they make money.

Use oil or silicone spray. Plain motor oil will work but will drip. The silicone spray not so much. This process is called lubrication. Moving metal parts need lubrication. Oil the springs, the cables and the rollers. Ball bearings need love too. Put a bit of oil in the curve of the track. Go on out to your garage and look; you'll see what I mean.

Make sure that the screws or teks that hold the hinges to the door are tight. They do loosen up on wood doors particularly.

If your garage door is suddenly REALLY heavy - STOP. You probably have a broken spring. If you try to run the garage door operator with a broken spring on your garage door, I will make MORE money. The electric operators are designed to pick up around six pounds. They break if they are asked to pick up all or half the weight of an overhead door. Lots of times, we can fix 'em, but why spend the money if you don't have to? Get your garage door spring replaced. If the door has 2 springs, you might as well replace 'em both. The other spring will break in a matter of weeks or months.

If your door has torsion springs, above the door around a steel shaft, call a professional. It doesn't have to be me, but call a pro. Torsion springs are dangerous. I pay the workman's compensation insurance here at the door company; everybody who makes a career out of overhead doors gets hurt by a torsion spring at some point. This has nothing to do with carelessness - torsion springs are dangerous. It has to do with torque. Look it up.

This one is rocket science, DO NOT LET YOUR KIDS PLAY WITH THE GARAGE DOOR! Please? If you get hurt messing around with the dern thing, that's your choice, but kids don't deserve to be exposed to this kind of stuff. I know, I got one of the only spankings my father ever gave me for playing with the door. I think I was maybe 4 or 5 years old and I was pushing the wall button and grabbing the rope and riding the door up. WHOOWHEE did I ever get a lickin'! But I never did it again. Overhead doors can kill.

That is enough for today.
