Customer stated he woke up and found that the house was cold. Found the thermostat blank and a flashing code on the furnace door. Upon arrival found thermostat blank and a flashing code of 24 on the board. 24 is “secondary low voltage fuse open” Found some wires crossed up from install and wiring on humidifier yesterday. Found W wire from thermostat got moved to the Common terminal on the board which caused the thermostat to blown the fuse when the furnace tried to turn on. Fixed wiring, replaced 3 amps fuse. Heat is running now.
