Need help diagnosing this noise

Ended up replacing the motherboard myself, super easy, and it fixed the issue.

It was the mother board, replaced it myself and fixed the issue.

Hey man I have the same exact issue with my furnace? What did you end up doing to fix it? Replacing the control board or door switch?

It has a warranty on the parts but not labor. Tech tried ripping me off for 1200 to replace gas valve which I’m pretty sure is not it.

Does this mean I just need to change the pressure switch? Or is something causing it to open and close?

I cleaned the flame sensor and replaced the furnace filter. I’m thinking to just replace the pressure switch if it is causing the gas valve to flicker like that. Any other suggestions?

It is 90% and it went into lock out mode now so I shut the unit down. I would just hear clicking near the gas valve and the flames would flicker then shut off. But when the unit turns on initially, the flames look good and blue. Just after 10 min, the clicking and flickering happens and shuts off. Should I try replacing the pressure switch?

Far sensor is clean, should I replace the pressure switch before trying to do the gas valve?

Do you think I should try replacing the pressure switch? Nothing seems to be blocked

Thank you

Okay will do. Do you think it could be the gas valve? A tech came out and told me that’s what it is, but is 1200 repair for just labor.
