Always check the user manual for the specific carbon monoxide detector model you have since the instructions may vary. For example, you may need to hold the button down for 5–10 seconds to fully reset it. Some carbon monoxide detectors automatically reset. After the alarm has gone off for about 5–10 minutes, it will turn off by itself.
If the alarm ever turns back on within 5 minutes of pressing the Reset button, then there’s a high concentration of carbon monoxide in the area. Get to fresh air immediately to avoid carbon monoxide poisoning.
Learn to recognize the signs of CO leaks in case your detector isn’t working properly, like yellow flames on appliances, condensation on windows, and flu-like symptoms.
Your CO detector may also flash an LED light whenever it sounds. Check the instruction manual to see what the number of flashes and light color mean.
Every model of carbon monoxide detector is different, so check the instructions to learn how to properly test it. If your alarm doesn’t beep, then you may need to replace the batteries.
