My dryer keeps setting off the carbon monoxide detector. I have checked it for lint buildup and there is none. It vents inside into a water holder and it has been very humid. Is there a problem with the dryer or is it all the humidity?

A common reason for a thermal cut-off fuse to blow is because there is a clog in your venting system.
So before you do anything, unplug the gas dryer from the wall outlet.
Turn off the gas (shut off valve) to the dryer.
Slowly pull the clothes dryer away from the wall; disconnect your vent line from the dryer. Then remove the lint screen from the dryer.
Using a lint screen brush, from the front of the dryer and with a vacuum hose (preferably a shop vac) connected to the back (bottom) end of the exhaust vent - do a thorough cleaning and remove all the lint.
(Note: I own rental property, so besides my own clothes dryer, I vacuum out my tenant\'s dryers at least once a year.using the LintEater Dryer Vent Cleaning System; http://www.rewci.com/lirodrveclki1.html
There\'s an instructional video on the same page- and no, I have no personal or financial interest in this company- just passing on good product information)
You\'ll want to clean the entire length of the duct work all the way out to the exhaust flap on the outside your house.
I\'m telling you this because if it is the thermal cut-off fuse that blew and you replace it while the venting system is still clogged, you\'ll end up with the same problem of blowing the fuse again; and risk the possibility of a fire or carbon monoxide poisoning.
BTW, make sure you are using rigid metal pipe for venting the exhaust from the dryer DO NOT use plastic, thin foil, or non-metallic flexible duct lines. Believe it or not, sometimes the lint fibers act like burning embers in the duct line, so you don\'t want them to burn through the flimsy material- and of course you don\'t want dangerous carbon monoxide gases that should be venting outside, - building up in your home. (As a matter of fact, I even have a carbon monoxide detector system monitored through my alarm company that covers my gas fired furnace, water heater, and dryer. I have seen first-hand the devastating effects from dryer fires; property, life, and limb!)
When you use rigid metal pipe for venting, don\'t screw the pieces together- the screws, when they protrude into the duct work, can catch lint; use HVAC / appliance rated duct tape to join and seal the duct joints together.
When you replace the thermal cut-off fuse you should replace the hi-limit thermostat too! They are usually sold as a set.
You can perform a continuity test on both parts to see if they are defective.
1.) Unplug the dryer. Remove the back panel
2.) Disconnect the wires from the thermal cut-off fuse and the hi-limit thermostat to test them. You\'ll need a multi-meter; you\'ll set the multu-tester to read resistance, measured in Ohms.
Set your multimeter to the R x 1 scale and touch the leads to the thermal cut-off fuse terminals to test for continuity. If you get an infinite reading, replace the cut-off fuse. It\'s the same testing procedure for testing the hi-limit thermostat.
For a visual "how to" testing procedures on the hi-limit thermostat go to:
Every year there are many deaths that could be avoided by a few simple checks, or the addition of a carbon monoxide detector in the home. The worst thing is that many of those people will have never known that they were under attack by a silent killer.
One of the products of the combustion of any fuel is carbon monoxide gas. The concentration of this gas can vary greatly depending on how complete the combustion process is. Many heating systems will check the combustion process and shut themselves down if the flame becomes too unstable and begins to produce harmful gases. There also are many heating systems still in service that do not check and will produce carbon monoxide gases. If carbon monoxide gas can get into your living environment then you and your family could be at risk.
To reduce the risk of carbon monoxide gas affecting your home, you should have your furnace checked every year. Make sure that the venting system of the furnace or boiler is in good condition. Make sure that the safety controls work properly and are not bypassed. Never bypass the safety controls to get heat even temporarily. Make sure that if you are using an unvented appliance in your home that you follow the instructions by opening a window a bit to give the heater fresh air. Many of these appliances have a oxygen sensor in them to protect you. Make sure to clean this device yearly and if the heater keeps going out and you don't know why, it could be because of oxygen depletion in the room.
Plugged chimneys, bad vent piping, wrong gas pressures, faulty, dirty burners, and many other things can cause carbon monoxide to build up in your home. Be careful to have all of these things checked often. If you heating system is not acting right then you need to have it checked immediately.
One of your best defenses against carbon monoxide is a detector. I like the ones that actually give you a digital read out of the level of the harmful gas in your home. You will find that even your gas range or oven will produce carbon monoxide and it is helpful to see when even low levels occur. The other reason is because the detectors that only give a warning on high levels will often not warn you till the gas reaches deadly levels. You want to be aware of these levels long before the reach deadly levels. This gives you time to get a problem identified and fixed. Also time to evacuate if necessary.
For best peace of mind, spend the money to buy a good quality carbon monoxide detector and then make sure you get it out of the bag and install it. Get your heating system serviced by a professional that can check the combustion process to make sure your heating system is burning cleanly and efficiently. By doing a few simple things you can protect yourself and the ones you love.
Water heater vent is supposed to be 4' or more away from any window that can draft air back into house, and never below a window or door opening. BUT. Call local plumber for local codes. Carbon monoxide is odorless gas, and poisonous to humans with headaches as first symptom. Install carbon monoxide detector in suspected areas.
I do not know of any reported problems specific to the Kidde CO/smoke alarm, but I spent a significant part of my career servicing toxic gas sensors and can give you some general advice:
1- Most important: treat an alarm as a REAL alarm and DO NOT suspect that your alarm is a "false alarm". My experience has been that most "false alarms" ARE REAL and the source needs to be identified! With Carbon Monoxide detectors, it is usually a blocked vent for a gas fired appliance- a hot water heater, furnace, or oven. Call your fire department or a service professional to make sure that there is no carbon monoxide. They have portable detectors that will be able to double check your alarm.
My advice to you at this moment is to act as if you have a real alarm condition and do not place you or others in a life threatening situation. Ventilate the room/ apartment/house IMMEDIATELY!
I will post more after I send this because you may be in a life threatening situation!
Hi, The burner may not be burning right and leaving a gas odor but you cannot smell CO it is totally odorless... that is why it is so dangerous... Check for lint build up in the air shutter of the burner...
Check your user manual for issues dealing with beeping alarms.
Your local fire department may be able to help educate you on the proper installation and use of Carbon Monoxide Detectors. A CO detector alarm should be taken seriously and you should follow the manufacturer procedures included in the package.
NEVER dismiss a Carbon Monoxide Detector Alarm for a malfunction.
ALWAYS treat an alarm as an emergency and follow manufacturer procedures.
Some models of Carbon Monoxide Detectors will give an audible beep every 25-30 seconds after it has sounded an alert alarm. This may have happened when there was noone home to hear it. A periodic beeping sound may also indicate it is time to change the battery.
Solution: Install a new battery and check your manual for instructions on how to reset the system. Check the expiry date on your unit, it needs to be replaced after 5 to 7 years, according to the manufacturer specifications.
If you are in doubt that your Carbon Monoxide Detector is not working effectively, REPLACE IT. Your safety and your peace of mind is worth it.

Hopefully you have found a solution for your Carbon Monoxide Detector issue of October 4, 2009. The best solution for a questionable CO dectector is a replacement.
A Carbon Monoxide Detector is the only thing that will read, detect and sound an alert when reads dangerous levels of CO levels in your house. A defective carbon monoxide detector will give you and your family a false sense of security and will give you no protection.
Whenever in doubt, always err on the safe side and replace Carbon Monoxide Dectectors, your life depends on it.
View my website for related information and compare brands and models of Carbon Monoxide Detectors available for sale online.
All carbon monoxide detectors have to be replaced after 5 years of manufacture date. The sensors are not reliable after that time and may give false readings.
A carbon monoxide detector is your only defense against the hazards of Carbon Monoxide Poisoning. I would never recommend installing a used Detector. Ask your local fire department for more professional advice on how and where you should install carbon monoxide detectors.
When a Carbon Monoxide Detector alarm goes off, you should follow the procedures that came with the manufacturer manual. Even when the alarm sounds, you cannot smell, taste, or see this dangerous silent killer known as Carbon Monoxide.
Have your house checked by your local fire department for possible levels of CO gas readings. If this all checks out, you can go online to Kidde Nighthawk website and find the manual for your Carbon Monoxide detector model.
