SOURCE: After programming my cars homelink to the genie

I haven't done this in a while, but I think that you have to program all remotes and the homelink at the same time. I believe that when you reprogram, the opener code changes.
Try this and if it doesn't work, don't accept my answer.

I have the same problem. Door does not open or close when press the push button and/or transmitter. The light flashes 5 times. Manually open or close the door is ok. On the manual troubleshoot, it says it's either the opener is overheated or it's on vocation mode. I don't know how to switch of vocation mode. Is it possible the thermal sensor is broken?
Can someone help?

SOURCE: My guardian garage door opener 21230L isn't opening and shutting when using the remote. It's definitely not the remote, as I detached the red cord to manually open and shut it now I always have to ope

If it makes noise and does not move mechanism, then drive gear(nylon) is stripped.

I have a problem with a guardian 21230L garage door opener when you push the button the light flashes but no door movement happens can you help cheers


if your saying that the light on door opener housing is flashing then stopping after a few moments , this is a sign of a fault in door safety's , either the door has to much friction now to move or beam detectors have sensed a problem

How do I remove the lens cover for the light on a Guardian garage door opener 21230L?


Not sure about the Guardian, but it should be in the installation manual which can be downloaded, if you don't have the original. On my "Linear" brand, you just have to press the plastic cover at the right place and it releases.

My Liftmaster garage door won't open or close. I hit the button and it make a sound and clicks but won't close


Remove the cover and check the drive gear. It is a white nylon gear just in front of the motor. It will be obvious if it is bad. Tell me - if it won't open how do you know it won't close?
