The sproket broke on my opener I don't know how although it was very cold and my son said it would not open one morning.
I replaced thr gears with a new kit and now the motor runs for about 3 seconds and then turns off. The green light blinks 5 times. I have messed with the limits and force settings yet it does not change. The opener is from 2000 and I don't know if it was something I did or just a coninsidence. Should I just buy a new opener? I seriously don't know what I did wrong. Thank you for your help.
