Question about Heating & Cooling

1 Answer

I have a frigidaire window unit. i cannot recall the exact # of the unit. but, my problem is that the unit still cools, but the smell it emits is similar to that of a wet dog. i opened the unit and cleaned the filter, i noticed there was what appeared to be a second filter, but i did not see a way to get it out. after cleaning the filter, i turned to unit on and got the same results. i think the unit # is something like FAM187STA

    thanks for the solution. i will try it and see if it works out. hopefully i will just find that the drain hole is clogged or something. otherwise to the drill. i feel confident about the solution given because the fact that the fact that the dampness not being able to evaporate makes sense as to the origin of the smell as well. thank you. teri

Hi, you cannot take out the second filter because you are not a tech in that field.
Many times when a wall or window a/c unit is installed the installer levels the unit.It should actually be lower on the outside end than the wall end. This keeps the condensate water from collecting in the pan waiting to evaporate.. There should be drain Hole or knock out at the condensor end of the pan. The condensor is the radiator looking thing outside. If nno hole can be found , one can be made but with extreme caution. A drill will puncture the condenser if it even bumps it..It is better and safer to remove the unit or at lest slide it forward out of the cabinet before drilling. That's the cabinet, now the pan needs a hole . making really no difference where as long as its away from anything the drill would damage. Once the water drains its a mater of keeping the filter clean. Household dirt and such really stinks when damp and the evaporator the filter covers is always damp.. Good luck and Make sure it drains into an area water won't cause damage.

Take care

My Frigidaire oven model feb386wech emits a burning plastic smell when heating up and cooking. What's causing this?

After 16 years of service, the oven may be starting to consume itself. I have found melted light fixtures and scorched, brittle wiring. If you can't isolate the source of the smell, it could be time to replace.

Brand-new window unit emits musty smell when compressor shuts off

It SHOULD NOT ... (smell in... even in WEST TEXAS).

BRAND NEW... Rush on down and get a good
NEW one.

I would suspect the condensate drip pan is plugged...

Common for AC units ..

But NEVER in "brand new"...

Get that (previously owned (my opinion)) UNIT
back from where you bought it ... Trade it in for a CLOSED BOX... and make your sales CLOWN write up why you are returning it.

Mold can be quite dangerous!!

Musty smell coning from window ac unit

You can spray glen 20 or similar into the return air filter with the unit running to kill the mould that is causing the smell, the other thing you can do is runn the unit on "fan only" mode for 20 mins after it has been in cooling mode before you turn it off. This dries the evaporator coil.

Our frigidaire FAC10SPP1a4 air conditioner is emitting a very foul smell. What could be the problem?

Air conditioners work by taking the moisture out of the air, and that water is put in a drain pan. Sometimes, the dirt and pollen will grow mold on that water and cause a foul smell. Bleach will kill it.

I have a Dometic Rm 2862 2-way about five years old.

Ammonia smell means cooling unit is done. Just double check on dometic site in case of any recalls that may apply. (

My Dometic trailer refridgerator is warm but freezer is freezing.


Unfortunately, you have a bad cooling unit in your refrigerator. Then ammonia smell means that you have a leak in the unit. TURN THE FRIDGE OFF!!! Do not use the fridge on AC or Gas until you have the cooling unit replaced or buy a new fridge. Depending on the model number and serial number of the fridge, it may be under recall by dometic and you might be able to have it repaired for free. If you will provide me with the model number, serial number and the serial number of the cooling unit (found on the outside of the unit in the fridge compartment, lower tank of cooling unit), I can then tell you the pricing of the repairs or whether it is under recall.

Again, TURN THE FRIDGE OFF and do not use it...RISK OF FIRE!!!!

Hope this helps,
