    Liftmaster 3800 Pro Install Trouble

    OK, I jinxed myself. After two days of working perfectly, it is back to the 12 light error meaning bad logic board. Anyone have an idea? Bad power supply? I will call them tmrw to explain. Very frustrating.

    Liftmaster 3800 Pro Install Trouble

    My overhead light that came with the opener works sometimes but usually doesn't come on. It has never flashed. I checked the collar for tightness and found that they were tightened but the set screws were not so I tightened them a bit. Liftmaster suggests that I mark he collar and the bar...

    Liftmaster 3800 Pro Install Trouble

    just went back out to check the door to see if it slows at closing. It doesn't. Unfortunately, the door came back up when I closed it. Good thing I haven't paid the installer in full yet. They have really given up on it and I think I would pay someone with experience to fix my issues. I will...

    Liftmaster 3800 Pro Install Trouble

    JOHNMAN, Number 2 was an issue. I now have the large door set where it will not bounce off the floor when closing. Thanks for your help. Travel limit was a problem. The remaining issue is when I open the door, it moves up an inch or two and stops. Hit the opener again and it opens fully...

    Liftmaster 3800 Pro Install Trouble

    I forgot to mention that the light on both units blink 12 times after this happens. Liftmaster support can't or won't tell me what this error means. It is not listed in the manual.

    Liftmaster 3800 Pro Install Trouble

    I had the local Overhead Door Co install my 18 x 8 and 8 x 8 insulated doors in my new garage about four weeks ago along with two 3800 jackmount openers. It was their first experience with these openers. My problem in both doors, but mainly the larger one will only stay closed for a few cycles...

    I have a few rust stains on our new polished concrete floors from nails left during the framing stage. What is the safest way to remove. Seems like acids hv the risk of whitening the spots. Do the organics work in a safer manner? I will be posting pics once we move in around 7-11. Hv been...

    Good stuff from Griots?

    I have a pc, cyclo, metabo rotary and a flex 3401. If you want to do paint correction instead of applying waxes and prewax cleaners you should look at the flex. Very well made, safer than rotary and much faster correction than a PC (or griots/meqs polishers). On topic. The only tools I have...
