My Kidde Carbon monoxide beeps every 30
L6 is actually "Lb", which is a low battery warning. If the 9V battery is missing, or if the battery's power is low, an "Lb" message will display, which blink's alternately with the current CO reading, while chirping. If this happens, you need to replace the battery.
Gives code l6
Perhaps that might actually be read as "Lb"? If so, it would indicate a low battery.
Model #KN-COPP-3..
1) Does the display show "Err"?
2) When you press 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 them 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.
Code 233 is showing on
According to Kidde, if any Error Code displays that is not referenced in the Owners Manual, you should contact Kidde for possible repair or replacement. You will need your proof of Purchase. Be patient when you call, there are a a lot of folks having this same problem with this combo detector.
