Depending on the brand.
Garage door not closing unless hold button.
Here is what happening.
When the door is up the sensor lights are off.
My genie garage door closes fine on all occasions but it won t open unless i hold the wall button down.
If anything interrupts this beam of light the garage door will not close and the ceiling light on the opener mechanism will flash as mentioned in the previous step.
I ve made sure there are no obstacles and that the sensors are aligned properly.
The first was checking and removing the light in the opener certain lights or looseness of fittings can cause frequencies that can disrupt the remote signal and is in play when the door is freshly opened but not when it has been closed for a while which explains the asymmetry.
Turn off the sure lock aka vacation mode on the wall console check if limits are properly set check the door balance condition and door spring check opening force control or force settings.
My garage door will not close unless i hold the button down.
After i hold the button down to close it the sensor lights come back on.
First check the sensor lights.
When this happens your garage door will only close by holding down on the wall button or wall console until the door fully closes.
Clutter or obstructions that block the sensor are the first problems to look for if your door won t close or in extreme cases open at all.
The transmitters remotes will not work to close the garage door.
When it is fully open or close left sensor solid red right sensor solid green.
You will find that the door will only move an inch or so in the close direction and reverse.
