Upon arrival found furnace calling for heat at thermostat but only fan was running found a couple issues. 1st one was high limit was disconnected causing unit to fault out and fan running. Once that was plugged back in correctly I tested unit and fan would still come on first befor inducer due to new ac 2 wire when placed in terminals was stripped to far and old humidifier wires that were still in place causing g to energize. I removed all old wiring to a humidifier that is no longer installed to eliminate any future problems. Warranty no charge install was done today.
