The answer to 'why is my carbon monoxide detector power surge' is that a power surge can cause a carbon monoxide detector to malfunction or shut off completely. Power surges can be caused by issues with the home's electrical system, severe weather, or faulty wiring. When a power surge occurs, it can overload the detector's internal components and disrupt its ability to properly monitor for carbon monoxide.
If your carbon monoxide detector is experiencing power surges, it's important to address the underlying cause to prevent further issues. This may involve checking your home's electrical panel, inspecting the wiring, or calling in a professional electrician to diagnose and repair any electrical problems.
