I have been having similar issues with my door but it is 10 yrs old with a 1
yr old opener. The friction is not an obvious obstruction and did get better
for a couple days after I re-lubed the hinges and rollers. Turns out the
bearing are going bad in a couple rollers which causes enough resistance that
it sets off the down pressure safety reverse . I replaced all the rollers
(only about $20) my self and no more problems. Nylon rollers are a good option
if you like a more quiet door operation.
