Next, check to see if your garage door operator is the problem. Do this by pulling the emergency release cord when the door is in the down position (so the door doesn’t come crashing down in case there is a problem). Then, try to lift the door up manually. Does it open easily? If so, your opener is probably at fault. If it still doesn’t move, the problem likely lies with your tracks, springs, or rollers.
How much should a garage door spring replacement cost? The national average is between $200 and $300 for a professional to come to your house and replace two springs. On line sources suggest a higher price of over $700 and that you will save $500 or more by replacing springs yourself. This is simply not true. To find the cost for replacing springs in your area look for a reputable company through Yelp or the Better Busienss Bureau. If clicking a site's BBB logo doesn't take you to the BBB site, we advise purchasing your springs from a different company.
My garage door has been acting up. Not wanting to work sometimes. I noticed the blue light flashing on the opener when I push the remote button. Today it will not open. That is the only way in, so I can't go in the garage from inside the house. I can't pull the cord to release the belt drive. How do I open it now? I never did run wires to the manual button into the house. I have to use the opener. Only have one I can find now. It is not working. I need in there now.

With over 300 independently moving parts, your garage door is a deceptively complex piece of equipment. To help prevent malfunctions and break-downs, it is a good idea to occasionally perform a garage door tune-up to keep all of these parts in good working order. A regular tune-up service by a Sears professional can prevent unexpected door problems and prolong the life of your existing equipment. http://m.youtu.be/Z_eZc-kh40c
