Foul odor coming from freezer.

Well an old remedy is to put a box of opened arm and hammer baking soda in the freezer and fridge to keep it from having bad odors.If that doesn't work you can try some charcoal it is perfect for absorbing odor, just don't use the matchlight kind or it will smell like lighter fluid.

If the odor is only present from the bottom of the fridge, and not inside the freezer or when it is shut, it is most likely spoiled something. Put everything in a few coolers, cover with ice and close up, spray out the fridge with some cleaner and let the freezer defrost if there is ice buildup on racks or surfaces. After the fridge is clean, I suggest using a box of baking soda to keep odors out of your fridge. Arm & Hammer recommends replacing these boxes every 30 days, but I've had mine in there for 6 months or so and it helps.

If your sure about spoiled food. Spoiled lemons are one of the worst, and the machine has not been abused, it's a problem of the selling dealer. Fan motors have been known to create an odor when their windings start to burn. Plastic items that become detached from the interior cabinet and wind up laying on the defrost heater which gets very hot during defrost is another, however, I would demand a service call (free) since everything on it is under warranty. Make sure it's creating the odor when the tech shows up.

you could possible be right on if your frig has an electronic disp control put your nose their and sniff if seem close to what you earlier smelled you solved your problem pcb control '

I had the same problem, but just fixed it. I have a maytag bottom freezer and when the fan blower comes on, there was a foul/stale smell that permeated the kitchen. There is no drip pan that I could remove to clean.

I just removed four screws from the back cover of the fan blower area, reached in with a small cup of organic odor remover and poured it into the drip pan just under the fan blower.

Any odor remover would work. probably vinegar or enzyme odor remover would work, too.

I now have fresh smell when the fan blower comes on.

I'm sorry that I don't have a solution, but we have the exact same problem with an older model KitchenAid side-by-side. Did you get this problem solved? If so, can you share what you did?

clean it with baking soda hot water and hair dryer

Clean the refrigerator thoroughly fresh food and freezer under all drawers. Then place charcoal briquettes in each 8 or 10 total. 4 or 5 in the bottom of the fresh food section. leave the for several days. If that doesnt take away the smell consider if a mouse may have gotten into a fan blade and well that can create a really bad smell.

There are a couple of methods to help remove odors from a fridge. The first is a cookie sheet with baking soda spread across it left in the fridge for several days. The other is something called Activated Carbon. Most stores sell it as a carbon odor filter and it is pretty cheap. It actually works better then the baking soda so I recommend you pick some up and just leave it inside the fridge. You can also put this behind your fridge or wherever you have foul odors. Hope this helps.

If the icemaker motor or heater short out it will cause a foul odor. I have never heard it described as cooked broccoli, but it can be pretty bad. Remove the icemaker and inspect the bottom of it where the heater element is and remove the white cover of the motor and look in there. You can take the three screws out of the motor module and see if anything is burned on it.
If you can rule out the icemaker, the next things to check would be the evaporator fan motor and defrost heater. Generally, if a fan motor starts causing an odor it will stop running completely and if a defrost heater goes out it will quit defrosting. It is possible, but unlikely, that something has gotten into the evaporator area and is sitting on the defrost heater so that it is "cooking" during the defrost cycle.
Check the icemaker first, it is the most likely cause of the odor. Post back with complete model number if you need further assistance and we will go through checking everything else.
