The answer to 'carbon monoxide detector power surge' is that a power surge can potentially damage or interfere with the operation of a carbon monoxide (CO) detector. This can happen if the surge causes a spike in voltage that the detector is not designed to handle.
Symptoms of a power surge affecting a CO detector may include the device not powering on, giving false alarms, or failing to detect dangerous CO levels. In some cases, the surge could even cause permanent damage to the detector's internal components.
