Some Professional Advice
These tried and true tips can help you avoid a lot of garage door related problems.
The most common opener problems
If you own a chain drive garage door opener, you must lubricate the chain often according to the unit's manual. You must check the wires and make sure the opener's sensors are well connected. Check the remote controls, too. Sometimes they need to be reprogrammed.
Change components before they break
Every main part of your garage door could potentially start to malfunction eventually. It's always preferable that you replace them all before this happens. Your manual should mention the expected lifespan for each component of your system, and although regular maintenance can keep them strong for longer than expected, it's impossible to completely avoid the gradual accumulation of wear and tear damage.
Check the reverse mechanism regularly
To make sure the reverse mechanism is operating properly, place a broomstick or a cardboard crate in the door's path. Now try to close it using your remote. If the door reverses the instant it touches the object you've placed in its path, the mechanism is likely in good working order. If it doesn't, you must avoid using your door until you get it professionally checked. Your safety could be in jeopardy.
