    Furnace Blower won't stay on
    I have a problem with my furnace blower not staying on. I can set my thermostat for say 74 degrees and the furnace will come on normally. I can hear and see the furnace on, but it takes roughly one minute (ive timed it) before the blower comes on. I know the minute delay is pretty normal; however, the problem is that the blower will stay on for exactly one minute then go back off for 30 seconds before coming back on. It will repeat this over and over again. The furnace stays on the whole time so I don't think "Cycling" as I read somewhere is the problem. I do not have much A/C Heating knowledge, but I'm pretty sure it should it stay on for longer periods. Am I correct?

    Thanks

    It definitely should stay on until after the furnace cools off when the gas goes off. It could be the relay that controls it, but I would look first at the temperature limit switch that controls it and any electronic control board.
