Maybe the battery died or a spring broke, but you can't get into the garage to even see what the problem is. If the garage door is the only way in or out, or if you can't find the key to the door, you'll have to either find a way to break in or call a locksmith. As a preventative measure, it's smart to keep a spare key or install an emergency key release that would allow you to release the emergency disconnect to the operator so you can manually raise the door.
The low rating on the CS is due to the fact that inwas out of town and my wife called because the garage door wouldn't open. We had repairs to the only other exit, and the CS said because it could be opened manually, it was no emergency. She was stuck in the house for over Sixteen hours. No emergency crew came out. Steve, a tech who came out the first time, fixed the door. It is not his fault CS took their sweet time to help a 45 year customer. I commend Steve. I do NOT have anything good to say about CS. http://www.youtube.com/watch?feature=player_embedded&v=Z_eZc-kh40c
R-value describes the power of the insulation in your door. The higher the r-value, the stronger the insulation. Those doors will have better energy efficiency than doors that have a low r-value. Basic doors have an r-value of 0.0 with no insulation. The first step up gives you 1-3/8” insulation at a 6.5 rating. Next, a 1-3/8” thickness with Intellicore has a 12.9 r-value. The best option on the market is the 18.4 r-value, which has 2” Intellicore insulation.
Scott was exceptionally polite, professional and knowledgeable. He thoroughly checked my garage door opener, but also inspected the garage door itself and pointed out rust and deterioration that has occurred. Scott then gave me a quote on a new garage door, explaining the installation procedure and quality elements of the new door including the warranty. I was very pleased with the entire service appointment, and my husband and I are seriously considering the new garage door, but only if Scott is the installer! Thanks, Scott!
Although garage door springs can break during any season and at any time, they most commonly break during the winter. This has to do with the temperature change. When the temperature sinks below a specific threshold, the metal will contract. This means it’s extremely possible for your door springs to shrink slightly during the winter months. This is hard on the springs and makes them more likely to break. https://youtu.be/Z_eZc-kh40c
