Back in the days when garage doors was simply made to keep your car under a roof are pretty much trouble free. Everything started to become complicated when they enclosed automatic opening features. Here are the most common problems of garage door openers. For adjustments and repairs that aren’t self-evident, it is best to examine the manual or call a professional.
Garage door opening without control: If the controls are left in the car, make sure nothing is sitting on them and compressing them. Assuming it is not; check if the control is dirty and grungy. A button that is even slightly stuck can trigger the garage door. To clean around the edges try using rubbing alcohol and a cotton swab. Try to remember if you changed the batteries recently if your garage door starts opening by itself. If you did, then take try nudging the battery connectors after taking the battery out because they can move a bit and press against the pad in such a way that the garage door trigger is set off.
Garage door opener only opening part of the way: It is most likely a sign of wearing parts. The springs located on each side of the door can lose tension over time and eventually stops helping the opener with the maneuvering of the door. This can be brought in excessive weight to the opener and it can jam or mistake the weight as a sign the door is closed. The motor and gears are very puny and sometimes even made of plastic, so it will definitely wear out as the opener lugs the door up and down repeatedly year after year. Take off the gunk and grease the gear mechanisms. You can fix it yourself, but a good garage door specialist is always worth bringing in.
Garage Door Opener Automatically Reverses: There are 2 sensors that are located on each side of the interior garage door frame. They send a signal to the motor unit, which will then refuse to close the door when something passes through them. It takes a few seconds to process this instance so the door moves some of the way and then reverses. The best solution is to lightly clean the lens of the sensors because normally the area around the bottom of the garage door is dusty and dirty and remove anything that blocks them.
Garage Door Opener Motor Runs: There might be a problem with the opener itself or with the chain section. Disengage the garage door by pulling on the release cable halfway between the garage door and the opener, making the door come down. Manually close or open the garage door to see if it still works. Click the opener to see if the gear assembly is broken, because they are normally put under a lot of strain every time the door is closed or opened. You can have the opener system fixed or replaced, but when the new gears may be so strong that they’ll immediately overwhelm the small motor and burn it out. To avoid this problem, it is recommended to just buy a new garage door opener.
When a Torsion Spring Snaps: A metal spring that has corroded would mean that the other springs are bound to break as well, and therefore need to be replaced. Call a repairman immediately to replace the springs. Always keep in mind that an ounce of prevention is worth a pound of cure. You can never go wrong with the services of a professional so you better rely on them.
