Moved thermostat - Now no heat.

I have relocated a thermostat that controls a ComfortMaker Model C9MPV075F12C1. The furnace functioned properly prior to the move. I was very careful in reconnecting the wires the same way they were disconnected. When the thermostat calls for heat, it clicks on, but nothing happens now at the furnace. No exhaust fan, no flame. The board fuse has not blown and I have tried a power off cycle to no avail. The LED diagnostic light is blinking "heartbeat" indicating no problems. Any suggestions?

On Houston204's advice, I rechecked all of the connections and wires for the umpteenth time, it came down to not enough insulation stripped from one wire. Thank you for giving me someplace to start!

I have heat again!!!
