Garage entrance is pretty large in size and so there are many complication involved in troubleshooting and repairing parts of a garage door. The two main types of garage doors are the traditional one-piece door and the sectional door. Both the types require heavy-duty springs that are capable of counterbalancing the heavy weight of the gate, enabling it to open and close easily. One-piece doors have a single pivot that is accountable for opening and closing of the door, whereas sectional doors have built-in parts that are pulled together with the aid of rollers and hinges. There are metal tracks that slide vertically. Large torsion springs are fixed on a duct above the entrance. Any of these parts can function improperly due to several factors. Some common issues have been discussed as follows: * Noisy rollers or hinges - Rollers and hinges can get clammy over time and make noises when operated. Such issues can be dealt with the application of a good quality lubricant (white lithium or silicone are commonly used). * Defective lock - Garage locks can operate improperly due to misusage and over usage. * Damaged springs - Springs that are used for garage doors usually have to withstand a lot of pressure. That is why, broken and defective springs need immediate replacement. Only technicians should undertake a task of repairing or replacing a garage door spring.. * Precariously balanced door - A door that is extremely difficult to open or close or the one that falls down immediately when released, should be checked by an expert technician without any delay. * Rollers off the tracks - This is a common problem that can have risky consequences. Faulty rollers can lead to imperfect functioning of your garage gate. * Optic sensor - If you are facing issues with closing of the door, you must check the infrared detector. With time, the lens of an optic sensor gets dirty or blocked by any object. If there is no trace of dirt then you must check the alignment of the sensor. * Loose metal tracks - Years of operation can make the metal tracks loose and unstable. Do check the tracks to ensure that they are capable to withstand the navigation of the heavy garage door.
