    I have a Lennox elite series furnace. The vents are just blow out cold air, not heat.
    I have a Lennox elite series furnace. The vents are just blow out cold air, not heat.
    The theromstat is now working strange.
    I set the digital theromstat at 75 deg. And then place the thermostat on hold.
    The temp. emediately goes to 65 deg. I went into the attic and looked at the system.
    I read the directions. I followed the directions; turn gas to off position, turn themostat to low,
    Turn electricity off to the unit, let sit for 5 minutes to clear, turn gas to on position, turn electricity
    On. The system still blows cold air, not heat? The thermostat is stll going from 75 deg. To 65 deg.
    I went back into the attic to review.. I looked through the plastic circular view glass. I noticed 2 green lights. The green light on the right is on, the green light on the left is blinking. Is this an indication that something is wrong. If so, what can I do the remedy the problem?

    Green light usually mean normal operation. The codes should be on the back of the furnace door, or in you owners manual
