It is not the battery problem, you need to get a replacement.
the circuite board is bad.

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.

I have a KIDDE / NIGHTHAWK Combo Smoke / CO Alarm (Model #KN-COSM-IB). It is "chirping" once every 30 seconds. I understand this is an indication of alarm malfunction. My question is: what do...


Normally, that means the battery(s) need changing.. But, hundreds people have had problems with this combo detector, it's hard to predict what it is.

But, as I said earlier, "Normally that means the battery(s) need changing." The keyword here is "Normally".

Good luck. I hope that solves your problem.

1. Change batteries.
2. Clean it.
3. Swap it with another location if you can.

If it still does not work properly consult the local fire dept. for free.

You may have to take it in repairs if all fails.

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.

My Kidde Model # KN-COEG-3 keeps going off and lists 217 now 205 now again 217 and this is with the door open and fresh air coming into my place ??


I took the following from the Kidde website. They only answer the phone Mon-Fri, from 8-5, EST. I checked it out because my almost new Kidde CO detector is showing an Error code.
The next time your carbon monoxide alarm has ERR on the display, push and hold the Peak Level button.You will see an E and an O followed by a number.Contact our hotline at 1-800-880-6788 and provide us the error code, along with the model number, assembly number and date of manufacture from the back of your unit.If your unit is under warranty, a replacement will be mailed to you.

My CO detector is chirping every 30 seconds or so, there is no battery to change and receiving error code 09


depending on what model number you have .. if its a model kn-cosm-b then is actually has 3 AA batteries inside ... the model kn-cob-lcb-a, while it runs on 120 volts, still has a 9 volt battery inside .. in fact most models have a battery backup so that they still work if there is a power outage .. the chirp indeed tells you that the backup battery needs changing .. if you cant find the battery give us the model number and we can help ... sometimes they are hard to find ..

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
