My garage door opener can open smoothly, but it only closes about half

down around half way. �The system seems fine - springs, cables,
rollers, etc. (I just installed a new SEAS garage door opener two
weeks ago and it worked fine until two days ago. �It's an old door

Any suggestions? �Thank you.

In addition to the other suggestions take a look at the garage door
opener track. If it's a two piece track the connection in the middle
may be misaligned and cause a hiccup in the middle.

whens the last time somone lubed the door tracks rollers etc?

often its never.........
