Anyone has Carrier HVAC units with pilot light? (furnaces, heating, gas)

[Ghost Town]

Hello!
Freezing temperatures are coming but I am still not ready for this nightmare. I have Carrier furnaces that have older design with pilot light.
The problem is that I cannot ignite pilot light on both furnaces. I followed the instructions and heard sound of gas passing through the main line but it didn't want to ignite. Seems like the small pilot light tubes are clogged on both units.
I tried to clean it but without luck. What would be the best way to do this? Does anyone have experience with Carrier furnaces? I'm not sure if I can reach those tiny holes (where the gas is supposed to pass through) without disassembling the whole thing.
Any recommendations on how I can do it myself? I know it is an easy way to call a contractor but I need to learn those small HVAC things myself.
Thanks in advance!

Thermal coupler is probably them problem. They are replaceable.

Thanks. But the gas just doesn't want to ignite. I am not sure if this is thermocouple related at all. As I see in that link, a thermocouple related issue is when the pilot ignites but then doesn't stay on. In my case it doesn't ignite at all.

Having the same problem on two machines at the same time implies that the problem lies
outside of the machines... things like fuel but most commonly the operator.

I followed the instructions and...

Invite your handiest neighbor over and have them try.
Be sure before you start taking things apart.

Once you're sure then start and yeah, the thermocouple is the weak link.
Many people will keep a $5 spare one around because eventually it will be needed.

Did you have the gas shut off for an extended period of time. If so it might take a while for the gas to get to the pilot to hold a flame. Just because you hear it (the gas) doesn't mean it has gotten that far yet.

Yes it was shut off for an extended period of time.
I will try again today, will see.
