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.

My Delta kitchen faucet is putting out small black particles with the hot water. What can I do to stop it?

Is the kitchen faucet the only problem? If not, then the water heater or other problem may exist in the water system.

When you run the hot water, are the particles always coming out or do they go away after while?

Black particles can be caused by carbon water filters. Do you have a filter? Those particles stop over time.

Washers and "O" rings that are wearing out can cause black particles. I would check under the sink to see if you have any slow drips. You may see white, green or black colors along the fittings.

I've also seen black particles from algae in the line. Maybe there's a leak somewhere in the system that dripping and cause the algae to form? Inspect your water lines and checking for leaks anywhere in the system may help. If you turn off all your faucets, washer, hose bibs and check the water meter, is it still moving? I'd check it every 15 minutes for an hour to see if there is a slow leak.

Here's a diagram that shows all the parts:

I'd also take out the aerator and see if it's clogged.

You may have to change the washers and "O" rings.

My Kenmore refrigerator has ice and water dispensers in the door...the problem is that the water that comes out has small white particles in it. The filter indicator light shows that the filter is good....

I would start by changing the filter more regulary. More than what the filter light says. The white particles is hard water deposits. I had the same problem and I just change the filter more that the light tells me and that solved my problem. Good luck.

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.
