Welcome to the Forum from Western NY!
It sounds like there's a short in the wire to the circuit board, or circuit board 'blower' circuit is bad. By any chance, did the battery ever get connected backwards at any time?
Here's a manual that shows wiring to the thermostat. It may contain more info than what you need, but it explains some wiring codes that may be helpful.
