My Freezer-Fridge has a terrible smell, almost smells rotton or like something died. What would cause that smell?

Check to see if the drip tray under or behind the fridge is full of old water of if a mouse died under it.

Hello Heather.
Have you had anything wrong with fridge that caused the smell.
Try charcoal in both fridge and freezer.
Hope it will help.
Fish smell is hard to get read off

first cut a potato in half and push it ion the middle of the freezer, it will absorb the airborne bacteria and reduce the smell . leave in freezer for about 2 hours then take out an throw away. next pour bicarbinate of soda into a bowl and put it into the freezer also leave overnight and smell should be gone

PUT A BOX OF BAKING SODA IN REFRIGE AND 1 INTO FREEZER ALSO. BUT TAKE EVERYTHING OUT, MAKE SURE NOTHING SPILLED AND IS UNDER A DRAW ROTTING. IF ALL IS CLEAN INSIDE, PULL OUT REFRIDGE IN BOTTOM BACK IS AN EVAPORATOR PAN FOR CONDENSATION, SOMETIMES SOMETHING CRAWLS UP INSIDE GETS TRAPPED AND DIES.
YUCKY BUT VERY REAL

Please note when you keep fish in freezer once, the smell will be longer even you remove it. O.K. Now solution for your problem- Please unplug power.Keep fridge door open. Take wet cloth dipped in soap water and clean all compartment including freezer . Keep freezer door also opened.Then clean with dry cloth. Spray room spray in your room not into the fridge. And allow 5 hrs to circulate fresh air to pass thr' your fridge and then close fridge and freezer doors. Plug fridge and run for one hour on empty. After one hour store items in fridge and/or freezer.
Keep all food items in closed style which will avoid odor spreading and also be a hygienic. Thanks.

did you flush out any drain holes with clorine bleach also if you have a drip tray is that clean.....?

You got some thing in the insulation...its done

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?

Not sure if engine coolant smells like rotten egs when it burns inside the cylinders , but it sounds like you may have blown a head gasket. Coolant and/or oil could be getting inside combustion chamber. Another possibility is that the catyletic converter might have broken up and colapsed onto the screen where it goes into the exhaust. Might give the rotten egg smell and block the exhaust enough to cause backpressure sufficient to cause the engine to run poorly too.
Try putting your palm over the exhaust pipe , if the exhaust is coming out in pulses (pop ,pop,pop) thats normal , if it is just slowly flowing out with no noticable pulses , I would check into the cat converter problem.

Hi - we had this problem, and it was in fact where some blood from a defrosting pice of meat drained into the compressor condensation tank and began to decay!

I agree the smell is terrible, so a good clean up is needed but this solves the problem immediately!

Kind regards,

Mike
