Garage door half open signal.
If the remote works only when held within a few feet of the motor unit rf interference is probably the problem.
When the garage door opener works intermittently the logic board may be experiencing radio frequency rf interference from nearby sources such as security lights ham radios and some electronics.
The antenna on the motor could be damaged or blocked from the signal.
I tested two remotes for this garage door and two other remotes for two other garage doors.
When this unusual problem occurs it means the up limit switch probably needs to be moved away from the motor unit.
If it happens at all it will usually be noticed when you first install the garage door opener.

The interference seems to last for an hour or two.
The remotes work by electronically sending a signal to the motor inside your garage allowing you to open and close the door.

The connection may not be real loose just enough that the small current draw of the receiver will not get through.
Troubleshooting a lost signal on your remote is as easy as resetting the old signal on the motor opener and equipping your transmitters with new signals.

When a garage door won t function properly the source of the problem could be in any number of given areas.
When your garage door won t open with the remote there are few things that can cause this problem.
If the door opens with the wall switch a simple battery change in the remote should do the trick.

In order to fix this you ll want to make small changes to the close limit setting until the door opener knows to stop once the door has reached the floor.
Depress the tabs on the underside of the cover at the back of the unit and remove the cover to expose the antenna connection.
All current genie garage door openers specifically work on 315mhz 390mhz dual frequency to help reduce the likeliness of experiencing radio frequency interference.
If your garage door is closing fully and then reversing to open again then it may be due to a problem with the close limit switch.
Garage door opens but the motor won t stop running.
None of them would work unless inside the garage standing nearly directly beneath the opener.
