    After I replaced my Humidifier filter my furnace doesn't work, why?
    I swapped out my regular filter and my furnace kicked on nicely. After I swapped out my humidifier filter the furnace doesn't come one. It makes a light buzzing noise and that's it. I have checked the circuit breaker, thermostat, power (everything is good), the light doesn't blink to indicate what is wrong, and the fan works just fine. Any suggestions?

    Most furnaces have a switch in a box on the side of the unit, did you flip your switch by chance?
