With the heatwave and stifling humidity, we have a black-type mold appearing on the unit. Does anyone know why that would happen and what to do? Thank you.

SOURCE: ptac fan keeps blowing

Try setting the fan control to "AUTO" this will cause it to cut out with the compressor.

Sounds like if this is a heat pump, maybe it tripped out on high pressure. Maybe just unplugging the system may reset the control boards. This maybe due to a dirty filter or dirty evaporator coil.

How can I know if there is mold growing my air ducts and filters?


If you or your family have been getting sick and there are no real outside signs from where the sickness is coming from, it is possible that you have mold in your air ducts. If you live in a humid climate you will have higher chances of having mold growing in the air ducts. To check you should call in a professional to make sure.

Any solutions for constant black mold growing in GE Monogram refrigerator? It is not a lack of cleaning problem. Never had a refrigerator do this before.


Permanently removing mold from a refrigerator is tricky because mold likes cold dark places (like refridgerators). However, I would try a stonger cleaning solution such as bleach. The attached link explains how to get rid of mold:

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.

Mold inside unit


There is a product on the market that will prevent mold from growing in your air conditioner.You should be able to find it at a refrigeration supply house.Just take the product and place it in the area where the water collects.There is also a product to help you clean your unit of contaminants on the heat exchanger surfaces.It simply sprays on,and can be later rinsed off.Its usually a straight forward matter to remove the cover from an air conditioner.Usually no more than 4 screws.Some units will slide out of their covers,after removing the screws that keep them locked in place,and some covers simply lift off from the rest of the unit once the screws are removed.In either case the rest of the unit minus the cover will remain intact,and can be cleaned.Cleaning the unit will almost always make it work better too,so your killing two birds with one stone.

Leave washer door slightly ajar after use to air out any moisture. Should prevent any future mold.

Moldy smell to air


I have a maytag ac unit that kept smelling moldy. We tried spraying with antifungal, only helped for a short time. I took the unit (ac unit slides out of window case) outside and carefully removed screws only to discover the fan was covered in mold!!!! Oh my what a horrible discovery! I washed the fan blades with bleach and water mix. I completely and carefully washed and wiped down the air conditioner careful around the control box. Then I let the unit sit outside in the sun untill completel dry. Good bye mold and fresh clean cool ac!! I will do this each year now that I saw that ugly mold!! That is definetly a health hazard! I would reccommend you either thouroughly clean your unit or pay someone to do it or get a new unit right away!! Don't use that moldy unit another day!! Good Luck!
