Overhead Door Troubleshooting
When your garage door does not open it causes considerable stress more so if you are in a hurry. A garage door has attachments of mechanical and electrical parts which work in perfect synchronization for its proper functioning. A couple of suspension springs on either side of the door, a torque spring at the door top, a chain pull or belt pull system, door rollers, and a guiding track for the door comprise the mechanical parts. These mechanical parts are found in all garage doors and could be operated manually.
Check the power cable connections of the door opener and the electric motor. Usually all connections of your house and garage are of ‘ground fault circuit interrupter’ (GFCI) type, which implies that all appliances are connected to one circuit. All the plug connections should be checked and tightened. Power supply could also be interrupted by circuit breakers. Even after having all electrical connections set up properly the garage door fails to open the defect might lie in the door opener or the electric motor.
The door opener receives impulses from a remote control on to sensors. Any damage in these would cause the opener to become inactive. During such times the opener is to be disengaged by pulling an emergency release system. Until the door opener or the motor is rectified the garage door is to be shut and opened manually.
The mechanical parts of a garage door are the torsion and supporting springs, lifting belts or chain, guiding track and door rollers. The electrical components include a door opener, an electric motor, sensors and a transmitter. All these individual parts need to be functional for smooth operation of your garage door.
It might happen that the door does not open when you press the transmitter. There could be a number of reasons for this. The foremost check is to be done for your door opener. This is an electrical device connecting the motor to the pulley system of your door. On receiving signals from transmitters the door opener activates the motor and the door is lifted up or brought down by the pulley system.
If after trying these basic troubleshooting tips you still cannot get your garage door to open, it is recommended to contact an authorized Sacramento overhead door service contractor.
