    Will it come back on if you immediately turn the thermostat up? If so, it could be a poorly calibrated thermostat. You may need to set it on 80 or something to hold the typical 72.

    Otherwise it could be a bad limit switch or relay. If you need help with them, post back giving more details of the furnace. I need more to go on than a Carrier Weather Maker.

    The furnace is a58sxc080-gg high ef. Carrier weathermaker furnace. It seems to cycle on and off a lot before reaching thermostat temp. We had a flood a while back so I had to replace motherboard and blower motor. The water came up as high as the vent motor but it still works. I have a new thermostat on now and have same problem.
