Everytime my mother cooks using the stove, the carbon monoxide detector goes off. It seems like every sunday when she cooks for a long period of time faithfully the detector goes off like an hour after the stove has been shut off. I take it down remove the battery and open the windows. about 20 minutes later i put it back up....no alarm goes off. the battery is new so that shouldnt be an issue. The only thing i am fearing is a possible gas leak. What should i do?


Answer
It could be a couple of things.
How old is the detector? They have a sensor that only lasts so long and they should be replaced every 5 years.
If your mother is cooking with gas is there an exhaust fan that removes the air to the outside of the house? If not it could be caused by the recirculation of the combustion air back into the flames.
A good flame should also be a light blue, if it is a lazy yellow flame then there isn't enough primary air (air that is mixed with the gas before combustion) if that is the case then you should ask someone who knows how to adjust it and they should also check for soot which may be evidence of flame impingement.
Gas, like electricity, it is safe if done properly but can be very dangerous if done wrong and Carbon monoxide is very dangerous and any warnings should not be ignored.

what could this weird gas smell from my gas stove?

the gas company came out and they guy had his detector or whatever. He said that it might be carbon monoxide and it might be incomplete combustion from one of the pilot lights and that they may need adjustment and that it wasn't a natural gas leak. I only smell it when I stand in front of the gas stove. He also recommended I open a door or window when I have the stove or oven on. He also pointed out the debris flakes under the stove cover as fuel debris or whatever. I put a carbon monoxide detector in the kitchen for about an hour and it didn't go off. What should I do? Call an appliance repair company? will it be expensive? Thanks!


Answer
I doubt that it would take a repair person very long, a service call, probably in the $45-$75 area depending on your location, plus time and materials, say another 1/2 hour. I'm guessing $100 total. You might well try this yourself. Go to a store that sells welders and welding supplies and ask for a "welding tip cleaner". It will be in the $5-7 range and is a small aluminum case with a series of round wires in various diameters, which are actually files. They are used to clean gas welding tips which have various sizes of orifices. Shut off the gas valve behind the stove, and use the tip cleaner to clean the pilot light orifices. The small files are flexible and will bend and you can increase to larger sizes until you feel metal to metal contact. Then, turn the gas back on and relight your pilots. If there is no improvement, you aren't out much, and the tip cleaner can come in handy. They are great for cleaning the windshield washer nozzles on your car. Good luck.
