my boss said his heat was broken and I work from his house on Wednesdays. I asked him to show it to me. He said it needs a flame sensor bc the flame shuts down immediately. I thought maybe it was an airflow issue and removed the cover to see if I take air was a problem. Nope. But I did notice the flame sensor looks like it’s on the last jet in the gas line, AND that jet wasn’t firing. I rubbed my finger over the jet and got it firing in just a few minutes. And this is after TWO hvac guys had been at his house and didn’t solve the problem. Apparently the first guy did do a cleaning, but it looks to me like the jets might be a little rusty. I’m going to guess maybe it was a rust flake.
Should my boss replace the entire pipe that’s beyond the gas metering device thing? He says he’s already gotten that replaced and has a spare (old?) one in a box.
What else to clean when furnace gas jets clog?

If it is working leave it as is until the weather cooperates. On a warm day I would remove and clean all the burners. Remove the gas manifold with the jets and make sure the manifold is clear nd remove and clean the jets.
Obviously, the tech that was there are useless.
Thank you! That sounds simple enough.
