My furnace went out. I put on a new thermostat hoping that was the problem. It wasn't.
I think it might need a thermocouple. I have a pilot light, the blower works, just no heat. Can I do this without blowing up my house??? I have no idea where to start. Or should I just call someone?

I would highly recommend you call someone. Natural gas is NOT something you want to experiment with.

I was afraid that would be the answer.
Thanks.

I used to own my own business called the House Doctor, and when it came to messing with old, dirty, natural gas furnaces, most often I would call in an HVAC guy. It's just the safe thing to do. You could level your house and kill people with one mistake.

If you have a pilot the problem is not the thermocouple. From what you describe I'd say It's an electrical component of the furnace (in the brain box) that commands gas to the burner. Of course that's based on limited information and there are several components in this box that control the gas flow to the burner.
If you have no clue call someone and hope for the best.

Someone was called; he didn't call back. I'll keep looking.

This could be a bad gas control valve too. How old is the unit?

It's a Lennox but so far haven't found the model number.
How could it be a bad valve if it's getting gas for the pilot?

Separate port and valve for the burner vs the pilot (all in one unit though) as I understand it. Hope for electrical that's way cheaper than a new gas control.
