It opens with the remote but won't close with the remote while the light is on. After the 4 1/2 minutes are up and the light goes off the remote works fine..
Things I tried:
Wall switch works all the time, light sensors are in alignment, removed the board and touched up some solder joints, regular light bulb, same issue after taking bulb out.
Something about that 4 1/2 minute light timer that disables the remote. Its a 20 year old Liftmaster 1/3 HP 41a4252-7d
