Carbon monoxide

[Toddm316]

Any known issues with carbon monoxide detectors just going off....for no reason

[rdrector]

Yes. Aerosols sprayed inside tend to dirty the sensor real fast. Hair spray, cooking grease etc. Once the sensor is dirty they go off intermittingly. Once dirty, they need replacing. I just use household carbon detectors now. A lot cheaper.

Try gently blowing out or vacuuming the sensor. Very likely it is a CO and LP combo sensor and you should check before replacing. Also, check the expiration date. Might have to take it off and look on back but they only last 5 years or so and will start alarming when their lifetime is over.

Please post make and model Rv for best advice.
