Furnace reignites randomly

[catour]

Hi, with the beginning of this heating season I noticed that my furnace burner sometimes reignites intermittently during burning. This is a high efficiency furnace and other than that strange thing it works well. I've shared a video which shows the issue. You can hear that clicking sound and see the burner goes off for a split second and then on again. This may repeat many times with random intervals until it stabilizes and goes on without interruptions. I would appreciate any suggestions on what it can be. Here is the video: https://youtu.be/ZlJiAyJSh1k

I have never seen that issue before but would suspect it is a control board issue or sensor. I would have a Tech come out and diagnose it to be sure.

Sure, I just want to gather more info on this before calling a technician.

I agree with Shannon, probably a bad pressure sensor.
But it could also be that the gas valve is faulty or clogged .
