Welcome. My name is ***** ***** would be glad to assist.

Let me be sure I understand the situation correctly.

If you push and release the wall button, the door will close normal?

If you push and release the remote button, the door does nothing? No noise or even a quick move and stop or return?

Let me know and we can continue,

Thanks

That's right wall contrill works fine.Remote opens fine but does not close. It you press to close the lift unit clicks in unison with the light going on and off. It's tries to engage and close but it stops.

Ok, thanks.

If the wall button works with only ONE push and release and not having to hold it down the whole time, then the issue is not associated with the safeties, so lets look further as it is an very extreme rarity for this to be taking place.

What is the Make and Model of the opener?

Thanks

Hi.....the wall button does not work with one push. you have to keep it depressed to open and close
Expert:  AssuredElectrical replied 1 year ago.

Ok,

So did this change or something?

The post prior stated the wall button worked fine?

Holding the button is not working fine, that is not normal.

Look at the safety eyes on each side of the door and see if either or both have small LED's lit?

Look on the opener and get the actual make and model number off the nameplate, on the front or rear. Look for a section labeled M or MOD or Model.

Thanks

Just for information, unless the opener is a commercial type the wall buttons only get a one push and release to operate.

All residentials work this way.

Will give you the information on what we perform in this situation on site with customers and you can follow the steps.

The symptom you are describing is usually related to a failure in your

safety sensors (photo eyes).When the (photo eyes) or associated wiring are malfunctioning,
the door will often open as normal with the remotes,and wall buttons however,
will not close with the remotes or keypad and will only close by keeping
constant pressure on the wall button.

The safety sensors are located at the door with one on each side facing
each other. Normally Each should have its own indicator light.
If one is amber and one green.
Amber is usually the sending unit and the green is the receiver.
So, if there is no green light, the sensor does not sense the area clear because of mis alignment, dirty lens, wires etc.

The safety sensors may be dirty. Wipe lenses with a damp cloth

They can easily become mis-aligned due to bumping,twisting and loose mounting and
can easily move when the door is moving along the track as it twists the rail slightly.
The safety sensors may be misaligned (This is the most common issue with
Garage Door openers). Make sure that all mounting brackets are tight.

Moving one of them just slightly can bring them into alignment, so caution on moving them too much at one time.
Watch the led lights on each one as you attempt to get them aligned, you will see one one of them light up if it
was out and that is the spot to hold it in place.

Test.
Open garage door, then look at the safety sensors. If they both have lights on then continue.
Then take an object large enough to set between the 2 sensors, and see what
the sensors do.-One turns off?
The key here is to see a change.

If there is a change, then remove the object and see that the lights
are back to normal.
Once back to normal, press the button on the remote and WATCH the sensor eyes
for even a FAST blink which will activate reverse and not allow the door to close

It only takes a split second blink on the sensor eyes to activate the reversing mechanism.
Many times it takes 2 people to watch, one on each side in order to catch the blinking.

Just reply after verifying and testing, hopefully the problem is cured with one of the two and the wiring is ok.

If that does not solve your problem,

Follow the wire from the ceiling opener terminals
all the way to the sensors to be sure they are not broken or damaged

Again, just an instant flicker will make the door reopen, so you must watch
very closely.
