    170-7 needs help

    Post  wstoneking on Mon Nov 08, 2010 1:15 pm

    I have (3) raynor 170-7's. Two work great. third needs TLC. A few days ago, it would open fine from either wall button, or remote, but on closing it only moves a few inches, never reversing, but just stopping. Just prior to that, the only way it would completly close, was to hold in the remote or wall button. I have no manuals, any body hav suggestions?---

    It sounds like the photo-eyes are either out of alignment or have failed. It will be easy to check since you have 2 other R170 openers.

    First check to make sure the photo-eyes haven't been knocked out of alignment. If they look like they're o.k. then remove a pair of photo-eyes from one of the working openers and see if the operator works. If the opener does work then you'll know that the photo-eyes were bad and need replaced.

    Swapped photo-cells with working door. No luck, Other door still works fine,no change in bad one. Alignment looks fine, light doesen't even flicker.I have released door from carrier, still only moves downward a few inches each time, after several attempts, It reverses and goes back to the full up position.

    Well, you've eliminated one possible problem. There are a couple other things to check. Does the operator open the door? If it does then you might want to check the Close Sensitivity. The force sensitivity screws are located at the rear of the powerhead near the top. The Close Sensitivity screw is on the right side (if you're looking at the back of the operator facing the garage door). If you turn the screw clockwise it will increase the down force. You'll only want to turn it a 1/2 turn at time and test the operator.

    If the above doesn't work then it's possible that the close sensitivity switch could be bad. It's also possible that the logic board could be damaged. If you remove the logic board and see any smoke marks on any of the circuits then the board will need replaced.

    It's just going to be trial and error until you can eliminate different scenarios and find the culprit.
