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.

fixed. i think we found the issue. rcvd a new logic board and once installed the big door works like a charm. now it slows at the last bit before sealing the door to the floor. i called support and told them and they are sending another board for the second door. this chamberlain support...

well i celebrated too soon i guess. the unit w/out the board problem is now up to the same problem. it worked for 2 or 3 days then started bouncing again....i am bewildered again. i taught the wife how to reset the units but i can't keep doing this everyday. the overhead door guy is...

Update. Today I had a new tech from overhead doors come out and the liftmaster tech support on the phone. The double door has a broken circuit on the board which will be will be replaced when we get the new one. I hope that is the problem. The smaller door seems to work now after some more...

thanks everyone....i am still working on it but having a hard time finding the time with work and all of the other new house chores. it still has me fooled but it will be solved.

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...

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...

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...

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.

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...

what you see in this pic is saw dust, not rust. the rust is on the first floor living area. the first stages of polishing was done before the roof was one so nails rusted after rains. i will give the suggestions a try. tks.

thank you. a friend said to try vinegar as well. What is TSP?

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...

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...

That site seems to put their sticker on a lot of other brands and do a lot of private label with chemical guys. I tend to buy from topoftheline, autogeek.net, autopia, properautocare, danase, finish kare and detailers paradise. have had good luck with all of them. What type of supplies are...

Beautiful. :thumbup: I have wondered about pergo as a flooring option. It is pretty tough stuff. Any problems with it? I love the loft!

I have almost forgot about this thread. Here are some newer pics including my new Wall Control system in powder coated black and red. Highly recommend it.

Your garage looks great my friend! Nice job. I wish I had that much space.

Great job on your garage! :thumbup: Nice monitor too.
