Narrowing down the specific malfunctioning component could help in assessing the proper garage door openers troubleshooting methods. Many garage door openers problems will keep the door from opening, which may be the result of broken springs or other parts. A worn extension door cable pulley is among one of the hardest garage door components to troubleshoot.

1. Garage door opener refuses to open garage the door at all. The cause of a garage door opener that refuses to open the garage door at all could be one of three problems: a broken torsion spring, broken extension spring or a bent track. Wear the appropriate safety gear before starting the garage door troubleshooting process, such as safety goggles, gloves and steel-toed shoes. Gather the appropriate materials for better accessibility, including the torsion, extension springs, vice grips, an adjustable wrench, winding bars and steel rods. Measure the old and new springs with a ruler or tape measure. Mark the torsion, extension or track shaft with a pen. Unwind the old springs. Loosen the torsion spring hardware with an adjustable wrench. Replace the springs or track as suited. Reinstall the torsion, extension and track hardware. Wind the new springs or track. Lubricate the door and reconnect the garage door opener.
2. Garage door opener refuses to open the garage door completely. The cause of a garage door opener that refuses to close the door all the way could be one of three problems: door binds in the tracks, a bent track or there are worn extension spring cable pulleys. Follow this general guideline to replace a bent hinge or roller. Remove the locking bolts and attach the hinge to the garage door with an adjustable wrench. Remove the hinge and roller at angle, then slide it from the garage door. Install the new hinge and roller. Slide the new roller on to the track. Attach the hinge to the garage door with an adjustable wrench.
3. The garage door opener refuses to keep the door open. The cause of a garage door opener that refuses to keep the garage door open might be due to a spring that has lodged into place. Locate the set spring, then use a pair of pliers to adjust the spring as needed.
