I just installed a new furnace and I hooked up the wires according to the instructions .
My furnace has a connection for Yellow White Green Red and a"C" The Instruction say to connect the Compressor to the "C" and one to the Yellow wire .The blower goes on , in fact even when I turn the heat on the blower will go on even if there isn't any flame .
I know it sounds like wiring ,but I connected it per the instructions.
Any ideas?

Normally the Yel=cooling contactor; white=heating; green=fan;red=24V power form transformer;blue=common. The low voltage wiring from the air handler must correspond at the thermostat
