A couple of day ago the furnace fan started cycling on and off avery ten seconds or so. . . usually just before the furnace comes on or after it goes off. I've checked the fan motor and the humidifier and everything seems fine. I thought that it may be running to humidify the house, but the cycles are way to short. . . Could it be a faulty thermostat (Hunter - 12 years old)?? Bad Fan?? Or just my imagination? Thanks!

Place fan to on position

Grab a stool,sit in front of your tstat,place fan to on.Allow fan to run for 2 or 3 minutes,do this several times.If your fan runs with no problem give us a call back.PDF

Type and age of furnace. Could be all three. Watch it work and give us a blow by blow.
