    HVAC question; DS1 & DS2 blinking .
    My hvac Lenox combo ac/heat (gas) isn't working as of last night. Blower comes on and fan is working as normal as well is the thermostat, however the a/c unit outside is not coming on and is new.2012 or so. On the furnace I located the circuit board and DS1 & DS2 LED'S are blinking non stop at one second intervals. Does this mean the board needs to be replaced? I have already reset the system by powering down and back on and got same results the system was serviced and recharged about two years ago. Please help it is frying hot in Arkansas today. Thanks a million

    Jumper Y to R on the furnace and see if the AC runs.
