Which element has a pungent smell - LG KU990 Viewty

Pungent smells inside can usually be removed with EITHER Chlorine Bleach OR Hydrogen Peroxide, but NOT together. Or Tilex is great for mold.

Also pull the whole thing out and look for deceased rodents or food that has been dropped behind it.

You must be referring to the pungent smell of formic acid. There are safety warnings about exposure to formic acid:

but I have no additional information about acute reactions to the smell. However, here is some painful information about insects:

I would remove the battery from the boat and take it to battery shop to have it tested. You may have a bad cell in the battery that is causing the charger to not shut off as it should.

clean well all the small drainage with bleaching liquid and soap it with scented soap.also at the back of the unit that are having small drainage and through the drain hose

You can try vineger towash it down just pour it in and let it work I would use a gallon. the onlyother thing you can do is chage the media and still wacsh it down with vinegar.. Hope this helps let me know Jon

Probably build up of dust and lint inside cabinet. You need to unplug dryer, remove back panel and vacuum out lint. If excessive lint found, would indicate insufficient cleaning of lint filter or restricted outflow vent or hose. If odour is electrical smell or burning plastic check all electrical connections and insulators for signs of browning or overheating. Strong pungent smell could be motor winding overloading or burning out. Will need electrician.

if its a sweet smell, and white smoke, antifreeze, acrid smell, wiring. oily smell, gray smoke, oil, rich pungent smell, black smoke, fuel. hope this helps!!!

There is a curing process for the foam used to insulate these. It can give off a pungent odor until it is fully cured. Only experienced it a couple times in the last 20 years. eric

the gym sock smell is antifreeze leaking into the compartment through a damaged heater core .

the moisture from a/c without any pungent smell is normal especially during cold mornings, the a/c is at peak performance thats all

If the monitor is working well you need not worry. If any electrolytic capacitor burst out this type smell may come.
