Question about Heating & Cooling
Cindi, Silly question, but have you verified that there is power to the furnace in the attic? Check the breaker in the fuse or breaker box and verify it is not tripped, and that the furnace is plugged into the receptacle next to it, or that the switch in the box next to the furnace is in the "on" position. That is step 1, If there is power, verify that the doors are all on correctly as there is a safety switch on the blower door that will not allow anything to happen if that door is not on all the way. If the furnace is new enough you should notice a small "window" in one of the doors, (usually round) after you complete step 1 and verify power, look into this small window and you should see a small blinking LED light. It may be red or green and there may be more than one. Verify the led is on. If it has a steady blink and you still have nothing happening, you probably need to get a technician involved.Some of the items that are listed by Travis1024 could cause a "no LED Light" situation, but it could be more involved. If there is no light and you feel comfortable looking at the circuit board (if so equipped) the 5 amp fuse that travis1024 refers to is on the board itself, it is a small tan automotive style fuse. You should be able to pull it out.. AFTER YOU UNPLUG THE UNIT AND VERIFY THERE IS NO POWER and look at it, there is a small "wire" you will be able to see, inside the fuse, that will be melted in half if that is the problem. Keep in mind fuses blow for a reason... the reason must be found and corrected before putting the unit back into operation or you will be right back where you started....sorry for the long post.. good luck, hope this helps!

If nothing is happening at all after the Thernostat has been changed I would say one of two things has happened. #1. The 5 amp fuse in the air handler (heater or indoor unit) has blown #2. The Transformer is bad. Also in the air handler. The only two things I can think of to cause your problem. Your not getting 24 volts to the stat I assume.

Try putting your fan in the on not auto position and see if your outdoor condensing unit cycles on and off. If it does you might have a defective time delay relay to blower. If not your contactor might be stuck or your thermostat could be defective.

Clicking sound is the contactor engaging to start the outside unit. Check for a burnt off wire at the contactor. For some reason you are not getting power to the outside unit. If you find a burnt off wire shut off all power to it then remake the connection at the point of the circuit break.

When the condenser coil is dirty come high pressure and cut out the compressor, you can wash with the garden hose around the condenser coil before disconect the unit for prevent any electrocution or the sistem is overcharged

SOURCE: Blower in Attic not running
inside unit has fan control relay , either on control board or can be separate ,except for the 24 volt transformer and the t-stat the units operate separately concentrate totally on the inside unit this is where the problem lies

The attic fan is not a part of your a/c system, and you should not run it while you are running the a/c. If you are currently using the attic fan, it is possible that someone wired it so that the a/c won't turn on while the attic fan is on. Otherwise if the thermostat is set below room temp, and says it is calling for cool, then the problem is most likely coming from an issue at the outside unit itself. Make sure to check your fuses, at the fuse panel and outside breaker. Hope this helps
FYI.. the only part of the system that might use batteries is the thermostat.
