A few months ago I purchased a 3/4-hp craftsman garage door opener for our new house which was under construction. Just recently I installed it for our seven foot garage door. It is a screw drive that I am familiar with with one problem, the door will only open to a maximum height of 6'. The older units had a contact that you could position on the track to set the opening height, this one does not. I am totally at wits end please help.

ONE1IAM - hi, I'm not really familiar with the Craftsman line but the last Genie screw drive garage door opener I installed did have a magnet you placed along the track for setting the door opening height. I'm sure it'd be obvious because it had a wire running from it to the main unit.

Another thought - is the system you have designed for a 7' door? I've seen kits that include an extra length of rail in the big box stores for taller doors. The box your opener came in might not have been labeled with the maximum height of door it could raise, and maybe the sales person didn't know to ask you about that.

Also - can you get the extra foot you need by attaching the opener to the garage door bracket's lowest mounting holes (the ones used to attach the opening mechanism of the screw drive to the bracket)?

Have you checked your unit for door opening adjustments - like small knobs or screws, accessible from the bottom of the unit, labeled UP and DOWN? On some older units, these adjustments set the resistance/pressure the unit would sense before reversing direction. On newer units they set the pressure as well as the height.

If your installation/owner's manual doesn't give you directions/troubleshooting tips, you may need to call the store and speak with someone there. You can also try their 1-800 number. I hope this is of some help to you. Good luck - regards! Jim D/West Point, VA
