Garage Door Opener Issue

[pinkoos]

In the past week or so, our door has been popping back open when it reaches maybe an inch away from the ground. It has been taking more and more open / close cycles before it finally stays closed

However, the last couple of days it just keeps popping open so it feels like whatever the issue is has progressively gotten worse

There are no obstructions that I can see and I've wiped down the sensors

Any ideas what this could be? Just trying to troubleshoot before we have to spend the money for a service call

We did replace the spring maybe a year or so ago so I can't imagine it's failing already though I guess it's possible

Also, this all started out of the blue - we had not made any changes to anything door or opener related

I can try any suggestion once I get back home from work this evening

Thanks
