This AM my heater did not come on. Thermostat clicking at temp, I jumped at the board. Still nothing. No indicator lights coming on.

Bad PC board, no high voltage, burnt fuse, bad transformer? Need to check for 24 volts from R and C thermostat terminals. If so then prob' a bad board. If not you need to see if high voltage is OK.
