The answer to 'why is my carbon monoxide detector circuit overload' is that the circuit has too much electrical current flowing through it, causing it to overload and potentially trip the circuit breaker. This can happen if the carbon monoxide detector is malfunctioning, drawing too much power, or if there is a wiring issue in the circuit.
Some common causes of a carbon monoxide detector circuit overload include a faulty or defective detector, a problem with the power supply, loose or damaged wiring, or an issue with the circuit breaker. Symptoms may include the detector not working, the circuit breaker tripping, or the detector beeping or flashing erratically. To resolve the issue, you may need to replace the detector, check the wiring, or reset the circuit breaker. If you are not comfortable troubleshooting electrical issues, it's best to call a licensed electrician to diagnose and repair the problem.
