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!

Hello Cindi,

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.

SOURCE: blower fan keeps shutting on/off,

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.

SOURCE: The outside unit is not working on my Heil Air conditioner

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.

My newly installed Broan-NuTone attic fan worked fine for two days. Now it wont turn off, even though the temperature has dropped well (40 degrees)below the setting(100 degrees).


Hi. The most likly cause of this type problem is the thermostat. Check the thermostat housing is it hot to the touch, is it close to a heat soarse, suchas, a motor or flu pipe for a water heater. If the thermostat has a adjustable heat range setting try setting it to the lowest setting if this shuts the unit off the calibration of the unit may not be set right. If the unit is new this should be covered under warranty.

No the fan out side is for a condensing unit and compressor. The compressor should not run with the heat. I am almost positive that if this is not a heat pump that the compressor unit should not be running.

Hello BWOOD Check the thermostat FAN button is in AUTO position not ON position.That might be it .The relay is in the blower unit but they RARELY become frozen/welded stuck on.

The contactor on the outside unit is sticking and must be replaced. The inside unit cycles off and the outside continues to run causing the refrigerant lines to freeze up.

Goodman compressor cuts off when temp too high


I believe you have 1 of 2 problems going on here your system may be overcharged causing the compressor to cut out on a overload relay circuit internally, or it also could be tripping out a high pressure switch which could be from an overcharged system or a dirty condenser. I would have the tech come out on a 90 degree day and put the gauges on and check the pressures while it is operating under a full load.

Hope this helps you.

Is your unit a Split system where one unit is inside (attic, garage, utility room) and another outside?? Is the outside unit unit running?? Is your thermostat electronic or the regular slide mechanical type??
