An extension spring counterbalance system consists of a pair of stretched springs running parallel to the horizontal tracks. The springs lift the door through a system of pulleys and counterbalance cables running from the bottom corner brackets through the pulleys. When the door is raised, the springs contract, thus lifting the door as the tension is released. Typically these springs are made of 11 gauge galvanized steel, and the lengths of these springs are based on the height of the garage door in question. Their lifting weight capacity can best be identified by the color that is painted on the ends of the springs.
If the remote works but the wall switch doesn’t, you may need to replace either the wall switch or the switch wires. To determine whether the switch or the wires are bad, first unscrew the switch from the wall and touch the two wires together (don’t worry, the wires are low voltage and won’t shock you). If the opener runs, you have a bad switch. If you have an older-model opener, a cheap doorbell button might work. If you have a newer opener that has a light and a locking option on the switch, buy the one designed for your model. A new one should cost you about $15.
