I replaced the thermocouple on my gas furnace last night because the pilot light wouldn't light. The furnace worked all night. This morning the pilot light went out again. What do I do now?:( :confused:

What happens when you try to relight the pilot? Have you carefully replaced the small draft door(s) on the water heater?

It's a gas furnace, not a water heater. I relit the pilot, a couple of times today. It seems to be working OK now. But what was happening was that when the burners fired up, I think it was blowing out the pilot light. Because the burners would make a very loud whoomp! Noise when they fired up. Why would the burners make such a loud noise? It was as if there was too much gas or oxygen. I was sure that I put everything back the way it was.
By the way, thanks for your help
