Trane XE80 blows cold air

[BradGo]

My furnace gets the call for heat from the thermostat, a fan starts (inducer?), a few clicks, the igniter glows for a few seconds, the bigger fan fires up, a few more clicks, the the igniter goes out. Installed a new controller board a few years ago, NO BLINKING CODES. No gas smell. So i assume that one of the control sysems is not allowing the board to send the gas signal to the gas valve (but shouldn’t that throw a blinking code?) or the actual gas valve itself is getting a signal to flow but the valve itself if failing. How to I troubleshoot? Is there a guide for expected behavior of each component? It the weekend, we’re freezing, and a repair guys can’t come out until Monday!!

Thanks!

Yes, you really have to find out the MAKE and MODEL to get good answers. There IS more than one machine made.
