Furnace ignitor clicking


Hi there, first post from me. I've got a problem with my Carrier 58GS-075 furnace that I'm trying to nail down. When the thermostat calls for heat from my furnace the pilot lights but the spark ignitor continues to click even after the pilot is lit. I have cleaned the spark electrode (the metal rod with orange tube coming from it) and it didn't seem to help any.

Also and more concerning to me is that occasionally when the burners ignite, they go out immediately, only to relight again. They ignite and go out several times before they stay lit and furnace operates normally then.

Thanks if you can help me out any. I did post a video of the ignition sequence on youtube to help troubleshoot this. Video Link

The device that the 3 wires attach to is a bimetal switch/flame sensor device. It hardens up with age and is not proving the pilot ON and needs to be replaced. They are not cheap $$.

What yuri said, you need to replace the pilot assembly.

Thanks for the response. In your opinion if I replaced that part could I keep the spark electrode with the white casing and orange tube, or does that need replaced as well at the same time?

And just to clarify, I attached a picture of the part that you think needs replaced...is this correct? 3 wire pilot burner. I found it online about $65, that sound about right?

Thanks again.

I've had the new pilot assembly in my furnace for a while now and it works great for the most part. It still clicks a lot though and it happens when the pilot flame is not in direct contact with the sensor. The flame jumps around a good bit and when it isn't contacting the sensor a spark clicks. Can I adjust the pilot flame so it is more steady and doesn't jump so much? Thanks for any help.

Joe
