garage door openers and/or springs..
my garage door is the old type solid folding door, not the newer fiber or sheet metal.. it's heavy.
one of the springs broke and that took out the door opener, as the nylon gears didn't stand a chance..
the springs are marked yellow, and I'm told that the painted mark is it's strenth .
is there any harm in using the next stronger spring to make manual opening easier?
and I've heard but never seen what they call safty cables that contain the springs incase they fail.. any insight there??
if I buy another opener whats better for a heavy door screw or chain drive..
I might see if sears can get replacement gears and if so, use what I have..
but it's at least 20+ years old..
thanks for any help.. as opening this with only one spring is back breaking
