My Kidde carbon monoxide alarm keeps beeping every 30 seconds and we have put new batteries in it but it keeps beeping

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

Are there any reported problems with the Firez 21007624 carbon monoxide detector false alarms?

I do not know of any reported problems specific to the Kidde CO/smoke alarm, but I spent a significant part of my career servicing toxic gas sensors and can give you some general advice:

1- Most important: treat an alarm as a REAL alarm and DO NOT suspect that your alarm is a "false alarm". My experience has been that most "false alarms" ARE REAL and the source needs to be identified! With Carbon Monoxide detectors, it is usually a blocked vent for a gas fired appliance- a hot water heater, furnace, or oven. Call your fire department or a service professional to make sure that there is no carbon monoxide. They have portable detectors that will be able to double check your alarm.

My advice to you at this moment is to act as if you have a real alarm condition and do not place you or others in a life threatening situation. Ventilate the room/ apartment/house IMMEDIATELY!

I will post more after I send this because you may be in a life threatening situation!

My detector is doing the one churp every 30 seconds which is indication of alarm malfunction. I have had it since Sept 2002. Is there anything I can do to correct this or is it beyone repair? I tried...

probably time for a new one. Most instructions for these types of units will tell you if it does the chirp after new batteries are installed, the unit has likely become defective. You got your money's worth from the unit. You can get better ones noew likely cheaper than the original one.

How to fix detector

You don't mention how old the detector is. If it is more than 5 years old the detector may be beeping to indicate the end of its service life. A smoke detector can last much longer but carbon monoxide detectors have a limited life span. If putting in new batteries doesn't fix the problem then most likely you will need to replace it.
