Fan blowing out damp odor

Are you loosing radiator fluid. sometimes the heater core will rupture and you will smell burn odor. also check for strange rubbing sounds or screeching coming from the blower fan motor. or engine exhaust manifolds are hot when car is on, make sure nothing is leaning on them which will cause a burn odor. Any odor coming from outside will find it's way inside through the fresh air vents.

Check your inside filter most often behind the glove box or in that area. It may just need changing or something got in it.

I fixed the bad odor problem once and for all!
This problem is caused by mold and mildew growing in a large ventilation hose that runs from the top of the wash drum to a large vent hole in back of the machine.

To correct this problem you can buy a kit from http://washerfan.com/ or do the cheap fix like I did.
Step One: Find the vent grille on the upper left corner of the machine. Remove the machine top, only a couple small screws hold it on.
Step two: Remove the hose clamps that hold the hose to the drum and grille then snap out the plastic grille.
Step three: The grille is convex so I used a belt sander to make it flat then I took a computer case fan that was the same size as the grill and hot glued it to the plastic grille. I wired it to an old 12 Volt phone charger (12V 500 Ma) and made it blow air INTO the vent.
Step Four: Put everything back together and enjoy a stink free washer because the mold can no longer grow in that hose.

Note! You must bleach, clean and scrub that crud out of that large vent hose and it is some kind of gross! If you're allergic to mold please wear respiratory protection. My fan has been blowing air into the washer 24/7 for six months and I have seen those case fans run non stop for years. It it dies just snap the hot glue beads and put another fan on it. Total cost for the entire fix, about $10.00

Also note that you have to leave the door open a little bit for the air that blows in the back to blow out the front door.

check defrost element wire maybe burning

Is it a musty smell or that of something / (rodent) decomposing? If you only smell it when it is running then look for BLACK gunk that will probably appear almost like a paste. Even things like cat or dog hair will collect in damp areas. There should be a white plastic drip pan under your unit. Look for the freezer white plastic drain hose on the rear bottom of your unit on the freezer side and follow that hose to the drip pan. It catches water every time the unit defrosts which is 3 - 4 times a day depending on which defrost timer your unit has.

Usually there is a build up in the drip pan that gets mucky and then stinks like mold. It will of course need cleaned.

Also look at the fan area for the coils. Sometimes there are unwanterd home critters that attempt to get through the running fan blades and end dead up inside the cooling coil metal radiator area.

since it is working ok . i am wondering if you dont have mold growing in the drip pan ... condensation from inside the refrigerator goes down a small tube in the back bottom of the frig ... that tube goes to a pan under the refrigerator and normally the water just evaporates .. if there is a lot of condensate from the frig then the pan may stay wet long enough for mold to get established ... a large amount of condensate from the frig usually indicates a leaky seal around the door .. or a door that doesnt close completely .. you might want to clean everything under the frig including any fans, coils and that pan (unplug first) ... now this all assumes that the smell is coming from the outside not inside the refrigerator .. if the smell is inside then you may have to defrost and clean the evaporator (the coils inside the freezer (somtimes also in the refrigerator) ... there are some kinds of mold that actually grow in that cold environment .. some hot soapy water with a little bleach usually does the job .. or if you have one, a steam cleaner, those do great .. it allows you to get down in the little places and clean everything ... make sure the frig is at room temp first so plastic doesnt crack ..
the refrigerant r22 or r134a have very little smell so even if you had a leak it wouldnt smell strong .. a few refrigerators use ammonia and that would have a distinctive smell easily recognized if there was a leak .

This is a sign of a short and should be looked at immediately. A smell like that is a sign of something burning. I could be the start relay and start capacitor with overload. But I would not sleep with the possibility of a fire. I will look over your model and see if I can find what this could be, Sea Breeze

clean it with baking soda hot water and hair dryer

you might ry removeing hte rear panel of freezer. gain access to the evapotator area, thats where the fan thatcirculates air is as well, if the smells stillback there washing the inside wont do anything. once fully exposed i would saturate area with an odor nuetralizer . I use odo-ban. and be sure to pour asolution of baking soda and water downt the drain assy (under the evaperator) that will allow the baking soda to reamin in the lower drip tray long after teh eater evaporates. once refrig gets vcold again the smells generrally disapate anyway

There is a very bad smell from the bottom of the refrigerator . There is a pan under the refrigerator with a very bad smelly Liquid , How can I clean that pan I couldn`t pull it out ? Thank you
