frigidaire with mold in water and ice cubes

[Rick52768]

 My frigidaire frig has a problem with floating black seaweed looking pieces (mold?) that come from both the water dispenser and the ice maker.  I am the original owner of both the frig and the house (4 yrs old) and have always replaced the PureSource2 water filter when the frig indicated it was time.  I added a whole house filter on the main house line to stop the frig filter from getting clogged from hard water which solved that problem, but did nothing to stop the floating black pieces.  The frig filter would ask to be replaced after 1-2 months with only two people in the house, so hard water was a very big issue.  The faucets do not show any issues when I clean the aerators, but the shower heads with rubber tits and the washing machine rubber door gasket show signs of darkening due to mold.  Is there I way to clean out the frig line, will this help and will it come back?  The problem is not new and we just lived with it, but seems to be worst than before.  What can I do to stop it?

The coating on the icemaker is coming off. May be cheaper to buy an add on icemaker for your frig.

[Rick52768]

Not that I doubt you know more than I will ever know about frigs, but the material is too thin and slimey to be a coating in my mind.

[theoldstoveguy]

Look at the sides of the icemaker and see if the coating has peeled off.(where the cubes are made)

[Rick52768]

Lucky or not I took the ice down where I can see the ice molds and I have no peeling. I was wondering I would see the film in the water dispenser if it was a problem with the ice maker. Any other ideas where to look? Thanks for help no matter what.

The only other thing to check would be the line behind the refrigerator going to the icemaker. I have seen slime in the lines as it can get warm and after the filter (removes chlorine) it can build up in the lines.

[Rick52768]

I will check that out. Are you talking about the line outside of the frig or inside the frig?

[theoldstoveguy]

Outside on the back wall. Use a flashlight and check the line for clairity.

[Rick52768]

The line is clear/green in color which leads me to believe that it has antimicrobial properties and when I put the flashlight behind the line I can see that it is clear of any material.  I think the problem is happening inside the unit.  I guess my next step is the remove the back cover from the inside rear of the freezer and see if that line is clear of material.  The rust coming from the some of the screws at the freezer back plate has me wondering if the humidity is too high in the freezer.  The frig is just over 4 years old but that plate looks like it is 15 years old due to the rust.  I cannot find a service manual to download on my PHS67EHSB6 to guide me, but I think I should be able to figure out how to remove the covers to expose the water line. Thanks

   Not that I have any idea what I'm talking about    but that is definately mold. Clean everything with a solution of baking soda and hot warer. Keep the Clorax away as some people say to use it 

[Rick52768]

Off subject somewhat, I have been told that mold loves the salts in bleach. I have to find the source of the mold to clean it.

[Icehouse]

Mold is from fungi and loves moisture and darkness 

[theoldstoveguy]

Mold usually needs warmth to grow. Never seen mold alive in a refrigerator.

[Icehouse]

What do you think clogs most drain lines?

[theoldstoveguy]

Warm air from the bottom of the line moves up, I've mostly found it plugged at the bottom with mold where it hits the tray.
