Central Heater does not work in Auto


Hi, I live in Florida and have a forced air central AC unit with 15kw heat. The AC works ok but the heater and air handler won't come on. All I hear is a relay or something that clicks like the heat is beginning come on. The air handler does not come on and I can see that electrical load is becoming lighter after a few seconds followed by another click. If I select the fan to run and I slide the heat on, it comes on running very well.
Incidentally, while running the heat in manual mode, I put the Auto/fan switch into auto and the fan speed dropped to half. I'm not sure if the airhandler is two speed or not. I seem to have both both phases working.

Thanks

Could be a bad sequencer.
