Question about Kidde Nighthawk Combo Gas/co Detector

Open Question

My nighthawk Carbon Monixide detector has been chirping for some time now thru the evening. There is a display that appears that is a picture illustration and is opposite the notation "Sensor>" When I push the test/Reset button I get readings from 150-224. After I reset it does nothing. The battery illustration shows the batteries are fully charged. My home phone is 719-533-1409 and my cell is 719-459-5209. Please help.

A reading of 221 ppm carbon monoxide gas is a dangerous level that should be taken seriously. You could try a new battery and reset the detector. If in doubt, always err on the cautious side and have the apartment checked by a professional or by the local fire department.

A new carbon monoxide detector is a small investment that may prevent carbon monoxide poisoning or death.

If the display shows "Err", push and hold the Peak Level button. Does the display change to "E09"? If so, then you have just been "had" by the grossly under-documented "planned obsolescence feature" called, rather matter-of-factly, "End of Life". This means that ~7 years after first being powered up, the unit will, BY DESIGN, cease to function, forcing you to buy a replacement. Would have been nice of Kidde to include THAT warning on the OUTSIDE of the package. Call their "Hotline" at 1-800-880-6788 and tell them what you think of that policy. If it is still under warranty (5 or 7 years depending on date of manufacture) they should replace it. In any event, buy another one; if they replace your first one you will have twice the protection. Not a bad thing. *Disclaimer: I am not a lawyer, despite the handle. Words to live by: "Every creative act results from a sudden cessation of stupidity." -Edwin H.

Constant problems with these combo detectors. My best suggestion is unplug it from the wall, remove the battery, leave the battery compartment open, then using a can of compressed air that has a straw nozzle (like you clean your computer with) blow the dust and lint out of the unit. Pay particular attention to the grill vents on the front. When doing all of this, hold the can of compressed air as upright as possible. Replace the battery and plug it back into the wall receptacle.

Hopefully, that will clear up the problem. and accumulation of dust and lint will cause them to false at times.

Pressing and holding the test button for 5 seconds is "supposed" to reset the detector.

We have a Kidde Nighthawk Carbon Monoxide detector. Last week our breaker tripped and ever since then our detector has been beeping once every 15-20 seconds. The detector has a code 97 displayed. We can...


Haha, same thing just happened to me and really scared me. Thats not a '97' that is an upside down 'Lb' for low battery. According to the manual: "A 9V battery is needed. If battery is low or missing while the unit is plugged into a 120V outlet, an "Lb" message will display which will blink alternately with a the CO reading every second and the sounder will chirp every 15 seconds."

I have 2 Kidde nighthawk carbon monoxide Manufactured 12/3/03 plugged in same day. They have no battery back up. They both began chirping within 4 hours of each other. Is there a built in expiration...


Yes, there is an expiration monitor. The chemical-based sensor degrades and should be replaced every seven years or so. (It's in the instruction manual). I don't know if the monitor is time-based or actually measures an electrical property of the sensor, but in either case, it's replacement time. At this point, the sensor is no long able to detect carbon monoxide.

From the Kidde support page on this topic:
"For quick replacement options, please email or call the Kidde Consumer Hotline at 1-800-880-6788."

My kidde carbon alarm chirp every 30 seconds and shows L6 on the dispaly, also the red light goes off and on


"L6" display & chirping sound, indicates you need to change the 9 volt battery in the detector.

If you have misplaced your User Guide, I have included a link to it, that you can download and print for future reference.

How long does the nighthawk model carbon monoxide detector last for.


I had 2 and they both did the ERR thing and stopped working within a week of each other and that was about 7 years.

Chirp every 30 second


Hi,

There are 2 things you can do:
1. Check and change batteries.
2. Clean them. Ensure they are completely clean.

If that does not work, you can ask the local fire dept. to look into it free.

Other than that you will have to take it in for servicing/repair.

I have 7 year old smoke and carbon monoxide alarm...I have put a new replacement battery and detector is chirping every 15 seconds or so


Check the expiry date on this unit. The manufacturer recommends replacement usually after 5 to 7 years depending on the model.

You bought a Combo Gas/CO Detector for protection against the hazards of Gas and Carbon Monoxide poisoning. A new unit will give you the peace of mind you are looking for.

Carbon monoxide detector err code


Detecotrs have a limited lifespan of 5-7 years. So sounds like you need new one (It's not worth to buy just a sensor). Take a look on amazon: Amazon com Carbon monoxide detector (watch out on reviews). I hope this was helpful. cheers
