Hi all, inexperienced when it comes to this but I need help and have a feeling it's an easy fix. I have a gas furnace and the pilot light has gone out when the heat clicks on about 5x the last month. The furnace continues to run, it just blows out cool air.

To fix it I would take a small piece of copper (from romex) and shove it in where the gray tubing goes that i circled in yellow. I shoved the copper where the tubing GOES, not inside the gray tubing as that was already cleared out.

From what I read online it seems a bad thermocouple could be the issue but most thermocouples I saw had copper tubing attached to it, and I do not see any copper tubing to anything in my furnace. So I was wondering if I needed to replace any of the pieces I circled in red (or if those are actually thermocouples themselves). Thank you guys for any help I appreciate it

That furnace has a flame sensor which sits beside the glow coil/HSI hot surface igniter which sits in front of the right burner.

Is there a LED error code window in the lower blower door with a LED which flashes a code when it acts up?

Clearing that port where the grey pressure switch hose attaches should only have to be done once every few years.

The LED error code should help you. The code should be on a sticker on the back of the door or inside or in the manual.

Check your intake and exhaust pipe for blockages outside as it sounds like a pressure switch problem.

Ive never noticed an LED error code but I will check back tomorrow to see and get back to this forum, thank you!

Flame sensor is on the ride side of burner.

Error light will be on the board in the blower compartment, which I believe is above your burner compartment.
