We have a problem with our garage door popping open involuntarily. We had our house built a year ago and the door has been popping up for at least 7 months out of the year. The builder tells us to call the electic contractor, the electric contractor tells us to call the electric company provider, who then refers us back to the builder. It happens mostly during power outages, but not always. We have 2 seperate garge doors and openers, but only one malfunctions. Can anyone provide some friendly advice on what we could do to stop the problem? Could there be a problem with the wiring?

It is not clear if you are still in the 1 year warantee or not.

But if you are then the BUILDER is the responsible person unless you DIRECTLY HIRED AND PAID the electrical contractor.

Call him dailly until something is done. If that does not work then start calling hourly.

Off hand I can think of 3 things that might cause this.

1. The insulation on the wire to the wall controller is cut. Or the wires where left long at one of th ends where they can touch each other.

2. There fault in the controller board.

3. There is another opener nearby, but not too close that ended up on the same code. With the rolling codes that most operators use today that would be very rare, but possible.

If your unit offers a Vacation mode you can use that to lock out the remotes and see if that helps.

I re-read your comment. It seems that this started well within the 1 year warantee period. If so and the builder let this run out without doing anything then you really need to get on them.

Specially as it might be the opener and they typically have a 1 year warantee on the basic unit.

BTW, there might be other people involved.

The electrican will have wired the ceiling receptacels for the openers. And they may or may not have prewired for the wall switches and the safety sensors.

But there is a good chance that the actual opener was installed by a diffent company. Most likely the company that installed the doors.

Many door operastors are now controlled by integrated circuits which makes the operator closer to a computer than the old fashioned relay/contactor type controlson the older operators.

It could very well be that this problem will be cured simply by changing the control card. The card may be generating a door up command whenever the unit powers back up after an outage.

Another possibility are the photocells that are used to detect obstructions. Normally, they are taken out of the control circuit when the door is within a couple of inches of being completely closed. A mis-adjusted or defective limit switch might allow the photocells to cause the door to open even if it is all the way down. This is easy to check, just block off one photoeye when the door is down. If it stays down, this is not the problem.

As Bill said, keep after the builder until this is fixed.
