Nordyne Furnace Model # L1RA 045N-08A. Blower runs constantly, whether the thermostat is on; no flame, no ignition, no heat. Have to turn off breaker for furnace to stop the blower. Red status light just steadily blinks on and off, not in a particular cadence. What do we do? Unit is not under warranty. I am an electrician and can repair myself with guidance.
Thanks

Actually it is model #GL1RA 108C-16B. I COPIED WRONG POST. SAME ISSUE THOUGH
