Open Sesame, close----------------

whatever. As long as the garage door will go up and down. We have had the local "experts" work on the door, at a cost of considerable $$$, several times in past months, and as usual, they would get it adjusted and working long enough to get their tools loaded, and get out of the driveway, and then it was back to it's old tricks. Mainly, that it would go down, the door would stop, bit the chain wouldn't, and then it would go back open again. We have been dealing with it, for a while, by waiting, with finger on button, until it got to the end of the travel, and punch the button the second time to stop it in place.
Except, it only did it part of the time, and then when you hit the button in anticipation, you started it back up yourself, and had to stop it and start all over. On one of the 'experts' last trips, they concluded that the 'eyes' that are required, (HA,) were defective, and sold Carol a new set, (which are mounted up at the ceiling, on the back of the drive, and totally non-functional,) which also did not correct the problem. (They have to be somewhere, to make the computerized controls think the area is clear.) I have adjusted the limits, down-force, etc several times, and within a day or so, it would act up again. Finally, Tuesday morning, when I tried again, the circuit board turned to toast, and the dorr would go down about 8 inches, and back up about 4 inches, each time the button was pushed. The particular opener model is only marginally serviced any more, a new board would have been $60-75, IF it was available at all. Ended up at Lowes, and got a new, screw-drive Genie, for about $200, a model with external limit switches, making adjustment much easier, and mechanical, not digital. Of course, buying it around 4 pm, and getting it installed before dark, (well, almost,) was a challenge, and it was 94 degrees in the carport. Also had a break in the control wire, between the unit and the wall switch, that was a bit of a challenge, but finally sorted that out. The drive is quieter, but not silent. (Never going to be silent, opening a steel door, with steel rollers! Think shaking a piece of sheet metal backstage, to make thunder sound for a stage play. Same effect.) But it is working!! Unit also came with a radio-type opener that mounts outside, with a numerical code, in case you don't have your clicker, plus our previous clickers, used in our vehicles, also are able to operate the new opener, so we have an abundance of clickers now. And I hope not to be climbing up and getting chummy with the opener for a long time!
Never would have gotten it all done so easily, except Princes the cat stayed close by, to supervise and answer questions, during the whole process.
