Suburban Furnace problem

I have a 2013 Puma 35qlb and my furnace won't do anything. I removed the furnace and found a white wire that had come unhooked. I'm not sure where it goes. I have 2 purple wires that go to the red wire on the furnace, a white wire that goes to the yellow wire on the furnace, and the 2 thermostat wires. I thought maybe the random white wire went with the other white wire and yellow wire but it still did nothing....
