I have a carrier furnace with a standing pilot light.
I can get the pilot light lit - no problem, it will stay on forever as long as I don't turn the thermostat up, and get the burners to light up. At first, when I turn up the thermostat, everything works as normal; the burners fire up and the blower comes on. I've replaced the filter and thermocouple, but once the furnace starts, it only stays on for about 5 min. Then it shuts down: first all the burners go out, then about 2 seconds later the pilot light goes out. The blower stays on through all this and will continue to stay on as long as the thermostat is up. I talked to a couple of HVAC guys about the issue. I was told it was either the a bad valve (i guess the main valve that the thermocouple and pilot light are connected to) or that I have a crack in something (can't remember the name of this part) and that it may be leaking carbon monoxide into my house. I don't believe these are the problems. The furnace is so close to working, I'm really hoping for a simple solution.
Any advice would be greatly appreciated, thanks in advance.
