Misterbb I have the same thing happen with the LG in my office. I took the unit out, then took it outside, sprayed the front and back coil will Greased Lighting or dishwashing detergent mixed with water and washed it down with a garden hose. What is happening if like mine is that the dirt and such has built up on your fan blade, condenser coil, and evap coil and the unit just needs a good cleaning. I use to work in a shop in Texas where we did a lot of window units and cleaning was just part of the job. The coils should be bright and blade clean. Also if you take the cover off you should oil the fan motor with a light weight household oil. Hope this helps.

Where can i buy filters


Amcor was bought out, and no longer supports this product or provides replacement parts for it. The unit has two filters:
  • Washable air filter which collects large dust particles and prevents bacteria build-up
  • An activated carbon filter to help remove odor
There is no manufacturer of filters (carbon or air) for this product, however if it were in my possession I would remove the carbon filter and take it into my local Home Depot or Lowes ( or whatever you have in your neighborhood) and see if they have something that might fit that is similar. Many filters work in more than one brand. The air filter should be washable still, if it is damaged you can probably do the same thing I suggested with the carbon filter.

I already sent in a question Order # 29744. Our window air conditioner Frigididaire Gallery blows out black particles about 1/8-1/4 inch in size. What is it? Is it dangerous? Please answer immediately. ...


Probably, what you're seeing is rust from the drain pan under the unit, that has become dislodged and is being picked up by the AC unit's fan or it could be the air intake filter breaking down and being blown in the house. Have you removed and inspected the air intake filter for dirt or clogs or deterioration ?

These are the things you need to inspect and troubleshoot first, to determine where they are coming from. If the unit is continuing to cool, as it should, I suspect that what I mentioned above may be the cause of the particles.

If it's the air intake filter replace it. If the particles appear to be rusty or slick, try flushing the drain pan under the outside of the unit. Be sure the outside of the unit is tiled down at least 1/4". Or it will not drain properly.

Is this a dangerous situation? I don't feel comfortable saying "Yes" or "No". But, it has to be a messy one. Be sure to turn the Master ON/OFF Switch to OFF and unplug the unit, before attempting to troubleshoot anything.

Hope this helps you to troubleshoot and solve the problem. Please let me know. Thanks

Water build up and spew into the room out ofvent


No. It should not spew water into the room. The drain pan is choked up. clean the drain pan and the problem will be solved.

Black particles coming out of the room air conditioner


dirt, dust, or mold. could also be the tubing insulation flaking off. either way, open it up and clean it out. the dirt, dust, and flaking insulation can restrict air flow through the coils and cause the ac to not function properly. if it is mold, it's can cause sickness (legionaire's disease). do not use chemicals on the coils. it might be best to replace the ac alltogether. to prevent mold: when installing the ac, make sure the unit is slightly tipped towards the outside. any condensation that collects on the coils will drain out. failure to do so will result in water pooling inside, and this can cause mold.

Too Hot to bare!


My Kenmore AC - #106-9752570 is also blowing out black particles that resemples felt. I put a new filter in a month ago. The button just above the on/off switch on the left front of unit has 3 settings (to the left/Fresh Air---to the right/Exhaust---and to the Top/Closed) The button is set on Closed & I can't move it to the 2 other settings. Could that be the problem?
