Hi Orval, Check the fuse on your 12V fuse panel, if ok, with T'Stat up check for 12V at the the circuit breaker/on off switch on the furnace or if it's tripped, if not ok (power), possible bad thermostat or wire loose somewhere, if ok, check for 12V at the power spade connector (PWR) on the circuit board, if ok, check for power from the blower spade connector (BLO) on the board, if ok, bad motor, if not, bad board. Good luck! |
